注：野生动物是 part of wildlife 以下是Wildlife:Wildlife includes all non-domesticated plants, animals and other organisms. Domesticating wild plant and animal species for human benefit has occurred many times all over the planet, and has a major impact on the environment, both positive and negative. Wildlife can be found in all ecosystems. Deserts, rain forests, plains, and other areas including the most developed urban sites, all have distinct forms of wildlife. While the term in popular culture usually refers to animals that are untouched by human factors, most scientists agree that wildlife around the world is impacted by human activities.Humans have historically tended to separate civilization from wildlife in a number of ways including the legal, social, and moral sense. This has been a reason for debate throughout recorded history. Religions have often declared certain animals to be sacred, and in modern times concern for the natural environment has provoked activists to protest the exploitation of wildlife for human benefit or entertainment. Literature has also made use of the traditional human separation from wildlife.

例文Dear WWF,I am writing to express my concerns about the protection of elephants. As we all know, elephants are one of the most magnificent creatures on earth and play an essential role in maintaining ecological balance. However, their populations have been declining in recent years due to various human activities such as poaching and habitat destruction.Therefore, I urge you to take action to protect these beautiful animals. One way to do this is by raising public awareness of the importance of elephant conservation. This can be achieved through education programs and media campaigns, which can educate people on the devastating effects of elephant poaching and encourage them to take action.Additionally, it is crucial to collaborate with governments, organizations, and local communities in conservation efforts. By promoting sustainable tourism and livelihoods for local people, we can help reduce the demand for ivory and protect elephant habitats.In conclusion, I hope that WWF will continue to work tirelessly to protect elephants and preserve their habitats. Every effort counts, and together, we can make a difference in saving these magnificent animals.Sincerely,Li Hua重点词汇：1. Magnificent (adj.) - 壮丽的，宏伟的2. Ecological balance (n.) - 生态平衡3.

Common Name Elephant ; Elephant (Fr); Elefante (Sp) Scientific Name Elephas maximus (southern Asia), Loxodonta africana (Africa) Location Africa, Asia These large and magnificent creatures need a lot of food and freedom if they are to survive. They wander in small to large herds over sometimes incredibly large areas while consuming up to several hundred kilogrammes of plant matter in a single day. Elephants, in fact, place such great demands on their own environment that in order to survive, it will frequently bring them into conflict with man who is competing for many of these same, often scarce resources. On the ground on two continents In all, the problems facing elephants in Asia and Africa are varied and complex. To this end, WWF is involved in their conservation through 2 key programmes which address local key issues, the realities faced on the ground, and this ever present conflict with man. These programmes are: Asian Rhinos and Elephants Action Strategy (AREAS): This ambitious Programme brings together cutting edge conservation biology with trade monitoring, socio-economic analysis, and policy advocacy, promising new hope for dwindling populations of these threatened pachyderms. WWF African Elephant Programme: The Programme aims to conserve forest and savanna elephant populations across Africa by supporting projects that improve protection and management, build capacity within range states, mitigate human-elephant conflict and reduce illegal trade. Physical Description Species Description Elephants are identified by their massive bodies and their trunk, which is used to pick a variety of objects, including food. The head is large in relation to the rest of the body and the African species is noted for its very large ears. Hair is sparse. The Asian elephant has four hooves (occasionally five) on the hind foot and five on the forefoot, and the African elephant has three on the hind foot and five on the forefoot. Size Living members of the order Proboscidea have a maximum height of nearly 400 cm and a weight of up to 7,500 kg. Habitat Biogeographic realm Indo-Malayan, Afrotropical Geographical Location Africa, Asia The giant panda has a very distinctive black-and-white coat, and adults measure around 1.5m long and around 75cm tall at the shoulder. Males can weigh up to 115 kg (253 pounds). Females are generally smaller than males, and can occasionally weigh up to 100 kg (220 pounds). Giant pandas live in mountainous regions, such as Sichuan, Gansu, Shaanxi, and Tibet. While the Chinese dragon has been historically a national emblem for China, since the latter half of the 20th century, the panda has also become an informal national emblem for China, and its image is found on many Chinese gold coins. Despite being taxonomically a carnivore, the panda has a diet that is primarily herbivorous, which almost exclusively consists of bamboo. This is an evolutionarily recent adaptation, or perhaps just a very awkward one; pandas lack the proper enzymes to digest bamboo efficiently, and thus derive little energy and little protein from it. While primarily herbivorus, the panda still retains decidedly ursine teeth, and will readily eat meat, fish, and eggs when available, but their sluggish speeds, a consequence of their mainly bamboo diet, ensure that these more energy-rich foods are seldom available to them outside of captivity. In captivity, zoos typically maintain the pandas" bamboo diet, though some will provide specially formulated biscuits or other dietary supplements. Unlike most bears, but like most subtropical mammals, the giant panda does not hibernate. For many decades the precise taxonomic classification of the panda was under debate as both the giant panda and the distantly related red panda share characteristics of both bears and raccoons. However, genetic testing suggests that giant pandas are true bears and part of the Ursidae family, though they differentiated early in history from the main ursine stock. The giant panda"s closest bear relative is the Spectacled Bear of South America. (Disagreement remains about whether or not the red panda belongs in Ursidae; the raccoon family, Procyonidae; or in its own family, Ailuridae.) Giant pandas are an endangered species, threatened by continued habitat loss and by a very low birthrate, both in the wild and in captivity. Poaching is uncommon; killing a panda was punishable in China by death until a 1997 law changed the penalty to 20 years imprisonment. The giant panda has an unusual paw, with a "thumb" and five fingers; the "thumb" is actually a modified sesamoid bone, which helps the panda to hold the bamboo while eating. Stephen Jay Gould wrote an essay about this, then used the title The Panda"s Thumb for a book of essays concerned with evolution and intelligent design. The giant panda has a short tail, approximately 15 cm long. The giant panda has long been a favorite of the public, at least partly on account of the fact that the species has an appealing baby-like cuteness that makes it seem to resemble a living teddy bear. The fact that it is usually depicted reclining peacefully eating bamboo, as opposed to hunting, also adds to its image of innocence. Though the giant panda is often assumed docile because of their cuteness, they have been known to attack humans, usually assumed to be out of irritation rather than predatory behavior. Giant pandas can usually live to be 20-30 years old while living in captivity. Until recently, scientists thought giant pandas spent most of their lives alone, with males and females meeting only during the breeding season. Recent studies paint a different picture, in which small groups of pandas share a large territory and sometimes meet outside the breeding season

Caused by desertification every year in direct economic losses amounted to more than 540 billion yuan. And the rate of annual expansion of 3,436 square kilometers. According to reportsmanagement, by 2010, China will strive to achieve the basicwho can basically be governed. Then caused the causes of north-western region, accounting for 34.6% of land area. 80% of the land has occurred in varying degrees of desertification. Resulting in about the causes of desertification in China, Ma Wenyuan, researchers believe that, with increasingly frequent dust storms, desertification has drawn increasing attention. The continuous , deforestation, excessive grazing, excessive, indiscriminate exploitation of water resources and hunting, And while many factors are usually additive effect, making China"s the growing trend of desertification. First, the abuse of Ken. Because of population growth and short-term benefits, many parts of the unplanned, uncontrolled for reclamation, weed cutting forests, but also not prepared soil and water conservation and ecological maintenance, leading to desertification, but also accelerate the desertification process in ecologically fragile areas, "opened a year pasture, RBI two years the amount of sand beams become three to five years, "occurs frequently. Second, deforestation. Because the main source of energy for the burning of arid areas of fuelwood, with the increase of population, residents cut down trees, and even used sand-fixing in the shelter were not spared. Third, and overgrazing. Because long-term overuse, such as desertification, Grassland overload rate of 50%, in part, I even up to 300%, not only caused large-scale grassland degradation, desertification, degradation of an annual rate of expansion of two or three Qianwan Mu, and grassland productivity than five decreased by about ten years on behalf of the 30% to 50%. Prairie "waist deep without the fifties and sixties did not hip, knee seventies and eighties did not ankle," the jingle vividly illustrate this dilemma. Fourth, excessive. Spring and autumn every year, the influx of large numbers of people in Inner Mongolia, Gansu and other exploitation of high economic value of licorice, seaweed and herbs, plus various types of large-scale deforestation, mining engineering weeding, removal of vegetation, resulting in large areas of forest, grassland desertification. Fifth, the abuse of water resources. As the Chinese way of irrigation, flood irrigation is still a serious waste of water resources, while the Northwest and North China drought, coupled with no rational allocation of water resources and management, excessive use of water upstream of the river, causing downstream water shortages, large areas of dead vegetation, land desertification . The local residents have over-grazing sheep, but also accelerates the grassland degradation, desertification rate, the current desertification area has reached sixty thousand square kilometers, to provide endless sources of sand dust storms; other use of water resources is not enough, a lot of exploitation of groundwater has resulted in ground vegetation withered, so large areas of dead ground vegetation, land degradation. VI hunting abuse. Economic value of wildlife-rich because of habitat destruction or by a large number of poaching, the number dropped, to maintain the ecosystem balance of the food chain imbalance, indirectly causing desertification. Such as the Qinghai vole was originally the hunting falcon eats a lot, due to a large number of stolen fishing, so that the proliferation of rodents, a large area grazed grassland, leading to desertification

Siberian Tiger (东北虎) The Siberian tiger (also known as the Amur, Korean, Manchurian, or North China tiger) is the largest and most powerful subspecies of naturally occurring feline. The Siberian tiger is almost totally confined to a very restricted part of eastern Russia, the Amur-Ussuri region of Primorye and Khabarovsk, a location it shares with the Siberian leopard, where they are now being actively protected. About 10% of Siberian tiger populations reside in China. The tiger population in the Sikhote-Alin was 250 in 1992, increasing to 350 as of 2004, despite significant losses of cubs due to car accidents on the single road that crosses their territory. Illegal poaching has been brought under control thanks to frequent road inspections. It is rumoured that there are still around 20 of these tigers in the Mount Changbai area of China. As the total population of these tigers fell to 150 in the wild, many subpopulations are possibly not genetically viable, subject to potentially catastrophic inbreeding. However, Russian conservation efforts have led to a revival of the subspecies, and the number of individuals in the Primorsky region of Russia has risen from 450 to 500 in the past decade, indicating positive growth.

Tigers (Latin:Panthera tigris, of Iranian origin: tighra) are mammals of the Felidae family and one of four "big cats" in the Panthera genus. They are predatory carnivores and the largest and most powerful of all living cat species. The Indian Subcontinent is home to more than 80% of the wild tigers in the world. Tigers breed well in captivity, and the captive population in the United States may rival the wild population of the world. Most tigers live in forests and grasslands (for which their camouflage is ideally suited). Among the big cats, only the tiger and jaguar are strong swimmers; tigers are often found bathing in ponds, lakes, and rivers. Tigers hunt alone and eat primarily medium-sized herbivores such as deer, wild pigs, and buffalo. However, they will also take larger or smaller prey on occasion. Humans are the tiger"s only serious predator and often kill tigers illegally for their fur or penises. Their bones and nearly all body parts are used in Chinese Medicine for a range of purported uses including pain killers and aphrodisiacs. Poaching for fur and destruction of habitat have greatly reduced tiger populations in the wild, and it has been placed on the endangered species list.

Title: The Amazing Giant PandaThe giant panda, also known as Ailuropoda melanoleuca, is one of the most beloved and iconic animals in the world. Native to the mountainous regions of central China, the panda is easily recognized by its distinct black and white fur pattern.Giant pandas have a unique and fascinating diet. They are primarily herbivores, with bamboo comprising 99% of their diet. They have a special adaptation in their digestive system to process bamboo efficiently. Despite being classified as carnivores, pandas have a thumb-like appendage, known as a "pseudo-thumb," which helps them grip and strip bamboo shoots.In terms of physical appearance, pandas have a stout body with round faces and expressive eyes. Their black ears, eye patches, legs, and shoulders contrast beautifully with their white torso. The panda"s friendly and innocent expression makes it incredibly adorable.Another interesting fact about pandas is their low reproductive rate. Females are fertile for only a few days each year, and the chances of successful mating are quite low. As a result, conservation efforts play a crucial role in ensuring the survival of these magnificent creatures. Giant pandas are considered an endangered species due to habitat loss and poaching.Efforts to protect pandas and their habitat have shown positive results. Conservation organizations work tirelessly to preserve bamboo forests and create protected areas where pandas can thrive. Breeding programs in captivity have also contributed to increasing the panda population.Beyond their conservation significance, pandas hold a special place in Chinese culture. They are often regarded as symbols of peace, friendship, and harmony. Giant pandas are beloved by people worldwide and have become ambassadors for wildlife conservation.In conclusion, giant pandas are extraordinary animals that captivate us with their unique appearance and gentle nature. They have become a symbol of conservation and inspire us to protect the natural world. Let us continue to appreciate and preserve the remarkable beauty of the giant panda for future generations to enjoy.

Major Threats to the Panda 1. Destruction of the panda"s natural habitat. In the eleven years from 1973 to 1984, suitable panda habitat shrunk by 50 per cent in six isolated, but otherwise ideal, areas. A 1998 logging ban implemented by the Chinese government helped to slow the habitat destruction, but poaching and illegal logging are still a problem. 2. Interruption of migration routes. Bamboo, the Panda"s main food, flowers (produces seeds and dies) once every 10 to 100 years depending on the species. When the bamboo in one area flowers, pandas have to move to areas that have not flowered. Historically, it was easy for pandas to move from one area to another, but now it is not. Human population has expanded, roads and settlements have been built, and forests have been cleared for agriculture, fuelwood, and timber. These changes make panda migration difficult, often leaving pandas restricted to "islands of forest."3. Consumption of Wild Meat Although pandas are occasionally hunted for their pelts, most pandas that are injured or killed by poachers are inadvertently harmed when the pandas are caught in traps meant for musk deer, takin, bear, and other animals. Wild meat is sold in the markets and restaurants in cities nearby the reserve. Eating wild meat in China is a threat to panda survival. (Note, pandas are not sought for use in traditional Chinese medicine.)Wanglang Protects the Giant Panda by:· Patrolling the Reserve for poachers and sick or injured pandas.· Protecting the forests as a key habitat area.· Educating visitors about panda protection and environmental issues.· Supporting panda research.· Providing a corridor for panda migration between adjacent panda habitats.· Educating local residents about the value of conserving pandas.· Supporting economic development of local communities to minimize their need to use panda habitat for to provide for their livelihood.How You Can Protect Pandas· Know and follow the regulations of the Reserve.· Don"t purchase or eat any kind of wild meat.· Make a donation to panda conservation at Wanglang Nature Reserve· Purchase souvenirs at the Reserve, a portion of which supports panda conservation programs at Wanglang.· Join an environmental organization to protect wildlife.· Tell a friend about Wanglang and panda protection.

1. 以东北虎为题写一篇400字作文 东北虎因为起源于亚洲的北部，所以又被称为西伯利亚虎。在历史上，东北虎又是位老寿星，有三百万年的进化史。东北虎是大型捕食性猛兽，身长体重，强悍凶猛，与其它虎种相较，个体最大，体色最美，堪称“百兽之王”。 东北虎是典型的林栖动物，在我国长白山区，主要生活在针阔叶林和阔叶林中的山崖间和山坡多石砬子的地方，也常到灌木丛和高草中觅食。 东北虎爪子长达十厘米，比钢刀还锋利，犬齿长达六厘米，犹如尖刀利剑。东北虎体型庞大，平均体长为2。8米左右，尾长0。9~1米。虎身条纹常为赤褐色，背毛长44~45厘米，腹毛长55~65毫米；夏毛较深，较短。东北虎的平均寿命约为20岁。 东北虎以捕猎动物为食，捕猎对象为狍子，鹿，野猪等有蹄动物；东北虎性极机警，走起路来和猫一样，毫无动静，行走能力很强，一昼夜能走八十至九十公里，跳跃高度达两米；东北虎还会游泳，但不会爬树。 在二十世纪初，我国长白山地区的东北虎有百头之多，但由于后来人类大面积砍伐森林，大量捕杀野生动物，处于食物链顶端的东北虎的食物被剥夺。此外，人类为取虎骨，虎皮而乱补滥杀的行为，目前，野生东北虎在中国的分布已退至松花江南岸，集中在中俄边境地带，数量仅为十只左右。 目前对东北虎的保护分两种方式，一种为栖息地保护，一种为异地保护。我国 *** 为保护东北虎建立了长白山自然综合保护区和黑龙江省七星砬子东北虎保护区，进行栖息地保护。而各个动物园，主要进行异地保护。 世界野生动物基金会已将东北虎列为全球十大濒危动物之首。 2. 以东北虎为题目,写一篇英语作文,写它少的原因以及解救它的措施 Siberian tiger is the largest subspecies of tiger.

And we should try our best to protect them.。 8. 关于东北虎的说明文 东北虎是现存体重最大的猫科亚种（除了杂交动物 狮虎兽），其中雄性从头到尾体长可达3.2米左右，尾长约1米，体长1.6~2.1米，一般体重150~250公斤，有记录的最大野生东北虎体重达到450公斤，为原苏联捕获。 东北虎主要分布于中国的东北地区，国外见于西伯利亚。体色夏毛棕黄色，冬毛淡黄色。 背部和体侧具有多条横列黑色窄条纹，通常2条靠近呈柳叶状。头大而圆，前额上的数条黑色横纹，中间常被串通，极似“王”字，故有“丛林之王”之美称（另一说法：“汉字‘王"，是根据虎头斑纹之状所造的象形文字”）。 耳短圆，背面黑色，中央带有1块白斑。犬栖居于森林、灌木和野草丛生的地带。 独居，无定居，具领域行为， 夜行性。感官敏锐，性凶猛，行动迅捷，善游泳。 捕食大中型哺乳动物， 偶食小型哺乳动物和鸟。[编辑本段]分化 在朝鲜半岛分布的虎，曾被认为是一个单独的亚种-----朝鲜虎（KOREAN TIGER）。 据说毛色和普通东北虎不同，而且体型要更小。朝鲜虎学名为Panthera tigris coreensis ，由Brass于1904年定名。 由于朝鲜半岛的虎几近灭绝，所以无从考证。在没有十分确切的证据下，国际上普遍把朝鲜半岛产的虎列类东北虎。 [编辑本段]生活习性 东北虎主要分布在我国东北的小兴安岭和长白山区。它体魄雄健，行动敏捷，肩高1米以上，身长2.8米左右，尾长约1米，体重可达350多公斤，有“丛林之王”的称号。 东北虎的毛色鲜明美丽，虎爪和犬齿利如钢刀，锋利无比，长度分别为6厘米和10厘米，是撕碎猎物时不可缺少的“餐刀”，也是它赖以生存的有力武器。它还有条钢管般的尾巴。 东北虎捕捉猎物时常常采取打埋伏的办法，悄悄地潜伏在灌木丛中，一旦目标接近，便“嗖”地窜出，扑倒猎物，或用尖爪抓住对方的颈部和吻部，用力把它的头扭断；或用利齿咬断对方喉咙；或猛力一掌击到对方颈椎骨，然后慢慢地吃。 东北虎一般住在600—1300米的高山针叶林地带或草丛中，主要靠捕捉野猪、黑鹿和狍子为生。 它白天常在树林里睡大觉，喜欢在傍晚或黎明前外出觅食，活动范围可达60平方公里以上。 常言道：“谈虎色变”，“望虎生畏”。 在人们心目中，老虎一直是危险而凶狠的动物。然而，在正常情况下东北虎一般不轻易伤害人畜，反而是捕捉破坏森林的野猪、狍子的神猎手，而且还是恶狼的死对头。 为了争夺食物，东北虎总是把狼赶出自己的活动地带。东北人外出时并不害怕碰见东北虎，而是担心遇上吃人的狼。 人们赞誉东北虎是“森林的保护者”。[编辑本段]生长繁殖 东北虎一年大部分时间都是四出游荡，独来独往，没有固定住所。 只是到了每年冬末春初的 *** 期，雄虎才筑巢，迎接雌虎。不久，雄虎多半不辞而别，把产仔、哺乳、养育的任务全部推给雌虎。 雌虎怀孕期约3个月，多在春夏之交或夏季产仔，每胎产2—4仔。雌虎生育之后，性情特别凶猛、机警。 它出去觅食时，总是小心谨慎地先把虎仔藏好，防止被人发现。回窝时往往不走原路，而是沿着山岩溜回来，不留一点痕迹。 虎仔稍大一点，母虎外出时将它们带在身边，教它们捕猎本领。一二年后，小虎就能独立活动。 东北虎的寿命一般为28年左右。 大约是人类的50到60岁。 [编辑本段]爆发力和攻击力 东北虎如传说的山神一样，拥有火一样的神灵目光。它的身体厚实而完美， 背部和前肢上的强劲的肌肉在运动中起伏，巨大的四肢推动向前，是那样的平稳和安静，看起来就象在丛林中滑行一样，它相对地拥有尖硬的锯牙钩爪，拥有5个非常锐利的虎爪，使用时伸出，不用时缩回爪鞘避免行走时摩擦地面。 它生性内向，胆小孤独、多疑、凶猛、强壮有力，动作敏捷，在丛林中出没无常，一般人很难亲眼目睹野生的东北虎。传统看法其它虎种均为东北虎向地球其它地区扩展分化出来的。 在生态环境中也处于顶层的王者地位。 中国科学家在解剖东北虎的时候，发现它的肌肉一打开之后，比最好的健美运动员的肌肉还要好看，还要结实，肌纤维极为粗，浑身上下，很少能找到多余的脂肪，几乎很难见到脂肪，强壮的骨骼附有强大的肌肉，证明这种动物有极强的爆发力。 虎的爆发力有过实证，在北京动物园狮虎山兽舍的水泥地面上有一道被东北虎抓裂的裂痕。剥掉皮的狮虎惊人的相似。 [编辑本段]种群现状 东北虎的经济价值极高，传统看法认为虎的肉和内脏可入药治疗多种慢性疾病，一只成年虎的价值相当于30多张黑貂皮，也只因为这样，东北虎遭到无情的捕杀。虎的繁殖率也较低，它的寿命一般为25年左右，三四岁时性成熟，每年12月至翌年2月 *** ，怀孕期105~110天左右，每胎一般产三四仔。 幼虎吮吸母亲乳汁长大，要跟随母虎一二年才独立生活。想想看，人们对东北虎的捕杀率大大超过它的繁殖率，这是东北虎濒临灭绝的直接原因。 滥伐森林、乱捕乱杀野生动物，严重地破坏生态平衡，也是造成东北虎濒临灭绝的另一个重要的间接原因。我们知道，森林是虎的生存环境，在这个环境中也包含着虎的猎食对象——野猪、鹿等。 近年来由于偷猎者甚多，致使虎的捕食动物也大为减少，因此，维持野猪、鹿等有蹄动物与虎之间的生态平衡是很重要的。据考查，在一。 9. 介绍老虎的作文250~300字以内 你养猫吗？老虎是猫科动物，但比其它猫科动物更具有猫科动物的特征，老虎很像猫。如果你在猫的额头画个“王”字，再把它放大几倍，就可以大致看到老虎的样子了。有个成语叫“照猫画虎”，很形象地说出了猫与老虎在外貌上的相似性。当然，老虎一般是黄色的，皮毛上有斑斓的条纹。白虎黑虎但闻其名，不见其物，流于传说罢了。 俗语说“猫是老虎的老师”，但显然老虎青出于蓝而胜于蓝了。老虎的威势不是猫能比滴。我们看到小猫发怒作势只会觉得可爱，不会感到恐惧，而老虎作势欲扑却能让人肝胆欲裂，魂飞魄散。即使在动物园，一只老虎瞪视着你，也能让你感到压力，浑身不自在。虎视眈眈，岂可小看？ 10. 介绍老虎的作文250~300字以内 你养猫吗？老虎是猫科动物，但比其它猫科动物更具有猫科动物的特征，老虎很像猫。 如果你在猫的额头画个“王”字，再把它放大几倍，就可以大致看到老虎的样子了。有个成语叫“照猫画虎”，很形象地说出了猫与老虎在外貌上的相似性。 当然，老虎一般是黄色的，皮毛上有斑斓的条纹。白虎黑虎但闻其名，不见其物，流于传说罢了。 俗语说“猫是老虎的老师”，但显然老虎青出于蓝而胜于蓝了。老虎的威势不是猫能比滴。 我们看到小猫发怒作势只会觉得可爱，不会感到恐惧，而老虎作势欲扑却能让人肝胆欲裂，魂飞魄散。即使在动物园，一只老虎瞪视着你，也能让你感到压力，浑身不自在。 虎视眈眈，岂可小看？。

If they are going to focus on something, they should do it on civil rights. 　　A: Yes, but we canu2019t deny that animals are vulnerable(脆弱的，易受伤的), defenseless(无防备的), and are completely at the mercy of human beings. 　　B: I understand your point, but we continue to have transgressions(违反，违法) against human rights. If so much attention werenu2019t devoted to the topic of animals, we would then concentrate more on saving a human being instead of protecting a koala. 　　A: You canu2019t compare apples and oranges; I believe that both topics are important and that we canu2019t ignore them, the mistreatment of animals can cause a great environmental imbalance. I believe that governments should prohibit activities like poaching. 　　B: Well, you are right on that point. This is the reason that I donu2019t buy leather and I try to buy synthetic(人工合成的) products. 　　A: At least youu2019re doing your part(帮助完成某个目标). My contribution is to have a pet in the house that I treat like a member of the family. 　　B: As long as you donu2019t treat it better than your wife, itu2019s fine. 　　关于保护动物英语对话2 　　保护野生动物 　　A; what do you think of the way people use and treat animals? 　　B: I think most people treat animals well, but we are often cruel to animals. When we raise animals or food, the conditions they live in are often poor. 　　A; perhaps people should stop eating animals. We could grow more crops. 　　B; what would you do with all the animas? You couldnu2019t just let them go. Besides, some people would still hunt them. Meat has become an integral part of our diet. 　　A; we could provide them with better conditions anyway. We should certainly try to improve the conditions at zoos. We should try to recreate the natural conditions as much as possible. 　　B: thatu2019s true. I think zoo are a good idea, because they allow people to get close to animals. I think itu2019s good for kids to see wild animals. 　　A; I agree. Iu2019m an adult and I love going to the zoo. I donu2019t like animals experiments though. I believe that we can do tests in other ways. 　　B; I read that the number of animals being used in experiments is falling dramatically as new techniques are being introduced. 　　A: thatu2019s good news. The good thing is that most people treat their pet well. 　　B; sometimes you read about people who have been cruel to pets or other animals, but those stories are rare. 　　A: have you every given money to any of the charities that take care of animals. 　　B: yes, I have. They do an excellent job. 　　A:你怎么了人们使用和对待动物的看法? 　　B：我想大多数人对待动物很好，但是我们经常残忍的动物。当我们提高食用动物方面，他们的生活条件往往很差。 　　A:也许市民应停止食用动物。我们可以种植更多的作物。 　　B:你会怎么做所有阿尼马斯?你不能只是让他们走。此外，一些人还会捕捉。肉已成为我们的饮食的一个组成部分。 　　A:我们可以提供更好的条件他们。我们当然要设法改善动物园的条件。我们应该努力创建尽可能的自然条件。 　　B：这是事实。我认为，动物园是一个好主意，因为它们让人们亲近动物。我认为，孩子们高兴地看到野生动物。 　　A:我同意。我是一个成年人，我喜欢去动物园。我不喜欢的动物实验，但没有。我相信我们可以在其他方面的测试。 　　B:我读的动物的数量正在实验中使用的是急剧下降的新技术正在实施之中。 　　A：这是好消息。令人欣慰的是，大多数人对待自己的宠物好。 　　B:有时你阅读的人谁被残酷的宠物或其他动物，但这些故事是罕见的。 　　A:每给你钱的慈善机构的任何照顾动物。 　　B:是的，我有。他们表现非常出色。 　　关于保护动物英语对话3 　　A: I do think people are consuming more and more habitat region of wild life. As authority has provided the number of wilds are decreasing, I think it due to man kind. 　　B: I couldn"t agree with you more. Last time I went to Sichuan, pandas can be found everywhere in the bamboo forest. But only 10 years has passed, panda merely can be found in zoos or protecting regions there. I think animal extinction is more and more common now. 　　C: I can only partly agree with former two, because I think animal"s termination is not to blame human only. Enviormental changes really matters to animals. Even global warming is not totally ours fault, it is reported by Australian researcher, herts of cows can leave tons of waste gases into the air daily which is tested out most CO2. That"s much more than human can produce a day. 　　D: Yes, I surpport C for evolutional theory of Darwin"s reason. I think species is developping their genes when passing down, maybe those extincting animals are those who don"t fit the surroundings?

The Tibetan antelope is a medium-sized bovid which is about 1.2 metres (4 feet) in height. It is native to the Tibetan plateau including China"s Tibet Autonomous Region, Qinghai province, and Xinjiang province; India near Ladakh and formerly western Nepal. The Tibetan antelope is also known commonly by its Tibetan name chiru. The coat is grey to reddish-brown, with a white underside. The males have long, curved-back horns which measure about 50 cm (20 inches) in length.Despite its classification in the Antilopinae subfamily, recent morphological and molecular evidence suggests that the Chiru is more closely allied to goats and the subfamily Caprinae (Gentry 1992, Gatesy et al. 1992, Ginsberg et al. 1999).Tibetan antelope are gregarious, sometimes congregating in herds hundreds strong. The females migrate up to 300 km yearly to calving grounds in the summer where they usually give birth to a single calf, and rejoin the males at the wintering grounds in late autumn (Schaller 1998). Chirus live on the high mountain steppes and semi-desert areas of the Tibetan plateau such as Kekexili, where they feed on various forb and grass species. The average life span is about eight years.Tibetan antelope are listed as endangered by the World Conservation Union and the United States Fish and Wildlife Service due to commercial poaching for their underwool, competition with local domesticated herds, and the development of their rangeland for gold mining. The Chiru"s wool, known as shahtoosh, is warm, soft and fine. The wool can only be obtained by killing the animal; Its numbers have dropped accordingly from nearly a million (estimated) at the turn of the 20th century to less than 75,000 today. The numbers continue to drop yearly. The struggle to stop illegal antelope hunting was portrayed in the 2004 film, Kekexili: Mountain Patrol.

ExtinctionExtinction is a natural process. Many species had ceased to exist before humans evolved. However, in the last 400 years, the number of animals and plants becoming extinct has reached crisis point. Human population levels have risen dramatically in the same time period and man"s predatory instincts combined with his ruthless consumption of natural resources are directly responsible for the situation. DodoThe Dodo is a classic example of how human behavior can cause irreparable damage to the earth"s biological diversity. The flightless Dodo was native to the Island of Mauritius in the Indian Ocean. It lived off fruit fallen from the island"s trees and lived unthreatened until humans arrived in 1505. The docile bird became a source of food for sailors and lacked the ability to protect itself from animals introduced to the island by humans such as pigs, monkeys and rats. The population of Dodos rapidly decreased and the last one was killed in 1681.Endangered AnimalsIn 2002 many animals remain threatened with extinction as a result of human activity. The World Wildlife Fund works tirelessly to raise awareness of the predicament facing these animals and find ways to protect them. By focusing on a number of high profile, "charismatic icons" such as the rhino, panda, whale and tiger, the WWF aims to communicate, "critically important environmental issues". The organization"s ultimate goal is to, "stop the degradation of the planet"s natural environment and to build a future in which humans live in harmony with nature".RhinosThe Rhino horn is a highly prized item for practitioners of Asian medicine. This has led to the animal being relentlessly hunted in its natural habitat. Once widespread in Africa and Eurasia, most rhinos now live in protected natural parks and reserves. Their numbers have rapidly decreased in the last 50 years, over half the remaining rhinos disappeared in the 1970s, and the animals remain under constant threat from poachers.The Giant PandaThe future of the WWF"s symbol is far from certain. As few as 1000 remain in the wild, living in small isolated groups. These groups have been cut off from each other as a result of deforestation and human expansion in to their natural habitat. The Chinese government has set up 33 panda reserves to protect these beautiful animals and made poaching them punishable with 20 years in prison. However, the panda"s distinct black and white patched coat fetches a high price on the black market and determined poachers still pose one of the most serious threats to the animals continued existence.WhalesThe International Whaling Commission meets every year. The agenda covers ways to ensure the survival of the species and the complex problems arising from countries such as Japan, wishing to hunt certain whales for "scientific" purposes. Despite the fact that one third the world"s oceans have been proclaimed whale sanctuaries, 7 out of 13 whale species remain endangered. The plight of the North Atlantic Right Whale is particularly serious. Hunted for their rich supply of oil, their numbers have dwindled to just 300. Collisions with ships, toxic pollution and becoming entangled in fishing nets are other major causes of whale deaths.TigersThe last 100 years has seen a 95% reduction in the numbers of remaining tigers to between 5000 and 7000 and The Bali, Javan, and Caspian tigers are already extinct. The South China tiger is precariously close to disappearing, with only 20 to 30 still alive. Like the Rhino horn, tiger bones and organs are sought after for traditional Chinese medicines. These items are traded illegally along with tiger skins.Take ActionThe WWF is actively involved in many areas of the world fighting to protect the natural habitats of endangered animals from further damage and curb the activities of poachers. They also work to influence governments and policy makers to introduce laws aimed at reducing the threat of pollution and deforestation. Our own individual efforts at home and in the workplace can also make a difference. By reducing waste and pollution, saving water, wood and energy, and reusing and recycling whenever possible, we can reduce the possibility of even more animals being lost, never to return.Your turnDo you think enough is being done to protect animals? If not, what else could be done? Send us your opinions.Far out into the ocean to the north and west of Britain are the cold wild islands of the Outer Hebrides of Scotland. They make a line of beautiful beaches 150 miles long. Further west is the small group of islands called Saint Kilda. They are cold and wild too, but without beaches. The islands are tall volcanic rocks hundreds of metres high. For thousands of years, people lived on these islands. In 1930 the last people, there were only 36 of them, had a meeting and decided to leave. The biggest island in the group is called Hirta. Sheep still live there without any people. When you arrive by boat, you see very tall black rocks all around. Some big rocks make their own small islands. This true story happened on the tallest of the rocks – “Stac An Armin” in 1840.In those days, people still lived on the islands of Saint Kilda. Their stone houses were all in one village by the ocean at the bottom of a tall dark hill. The houses only had one room – for people and sheep, which used to live with them in the winter and spring. Two men from the village, McDonald and McKinnon, were on the rock. It was their work to collect birds – some for food, some to make shoes or hats with. Some dead birds they put in the earth to help their vegetables grow. They found one strange big bird. It was sleeping. They decided to bring it home to the village.I think people in the village were interested in the bird. We now know that this was a Great Auk, a kind of swimming bird that lived in many parts of the North Atlantic. It was big and strong and had a loud cry. They began to talk with the other people in the village about what they should do with it. After two days, the weather got worse and then there was a terrible storm. The people in the village decided that this was because of the bird and they killed it. This was the last example of the Great Auk in Britain. Four years later, the last Great Auk in the world died in Iceland.We know the Great Auk died out because of people. But where did the people of Saint Kilda go? This is more difficult to explain. Some say that they were bored living on the island so far from modern cities. Other people think that the problem was tourists, who began to visit Saint Kilda at the end of the 19th century. A new theory says that using too many dead birds as fertilizer made their food unhealthy. I think it was a mistake to kill the auk.mistake that resulted in killing this bird. The day after the people brought the bird home, the weather got worse and worse. At that time, they had less knowledge about nature, they could only believe in God to help them decide what was wrong and what was right. So it was so easy to make mistake about what they didn"t know and it happened by mistake. The article is very clear about that. But at the first they thought they should bring it home and kill it for food. That is not good. Unfortunately, it was the last bird.”Oswaldo Herrera writes “This article is very interesting, and we need to think about it. Nowadays we are destroying our world and furthermore, the animals and plants that exist in it. There are a lot of warnings but most of the time we do not care about them - I think that this articles helps us to reflect and to be conscious about all the animals and plants that we are destroying with all the pollution that we generate nowadays.”

至此粉红电影进入了它最为辉煌的年代，直到1973年。这一时期粉红电影无论从创作的数量还是水准上都是极为成功的。粉红电影数量占到了整个日本国内电影数量的一半以上。仅日本东京就有大约500家的成人影院播放粉红电影。进入70年代后，迫于经济困难的原因，早些时候制作粉红电影的电影公司从5家变成了3家。其中两家日活和东映开始制作成人电影。20世纪70年代中期日活又出现了新的电影类型SM Pink，代表作是小沼胜导演的《受辱的妻子》，该片是日活第一部取得巨大成功的SM影片 。又一位代表人物田中登则以Angel Guts 系列开创了Violent Pink电影的先河。另外一家公司东映所拍摄的相同题材的电影叫做Pinky Violence，代表作包括铃木则文的《兽欲学园》。粉红电影和早期的浪漫色情电影应该是很相似的，影片拍摄的媒质都是胶片，可以称为电影。有剧本，需要后期的声音合成，影片时长都控制在1个小时左右。粉红电影有着严格的预算限制，但Roman pornography的制作费用是十分可观的。这一点是与粉红电影最大的不同之处。Roman pornography通常的制作周期为一周到十天。粉红电影中的性爱场面是一种形式，没有真正发生的。而在后期的Roman pornography和AV中性爱场面大部分是确实发生的。这些场面由于日本电影制度的要求是要打码的。直到今天AV也都是要求有马赛克的，无论是薄码还是厚码。而我们看到的无码AV其实是违法的。在粉红电影中我们是看不到马赛克的，一个原因是源于导演对镜头的处理和把握。另外制作公司没有足够的资金去后期处理增加马赛克。后期的Roman pornography是日本AV的雏形，AV的拍摄媒质是录映带，不能视为电影。不过在时间长度上依然继承着1小时作用的传统。随着20世纪80年代后AV的风靡，Roman pornography这一类型电影也逐渐消失，而粉红电影则逐渐发展为主流电影，电影长度由60分钟，增加到90分钟，一部标准电影的时长。日活公司粉红电影时代和浪漫色情电影时代的代表分别是若松孝二和若松孝二有粉红电影教父之称，是日本电影历史上最为坚挺的导演。不仅内容广泛，题材也极具争议。除了宣扬porno之外，命运，人性，政治，暴力等诸多元素也使得他的电影极为绚烂但也极为晦涩。他是日活公司早期的代表人物之一。1965年若松离开了日活，因为日活不支持他颇具争议的电影Secret Act Behind Walls参展柏林国际电影节。不用受到电影公司体制的约束之后，若松孝二开始了他对立的创作，他的个人风格的特点更加突出。甚至变得有些狂野。这一时期的作品耸人听闻，离奇古怪，超现实超自然。比如Contemporary History Of Rape In Japan　，When The Embryo（胚胎） Goes Poaching（水煮） ，Ecstasy Of The Angels都是最好的体现。若松孝二是至今仍然活跃在日本影坛的老导演之一。最近的一部作品是《完全饲育之赤色杀机》。 神代辰巳是日活Roman porno绝对代表人物，有着日活porno之王的美誉。神代是一位游走在日本主流和非主流之间最成功的一位导演，他的作品无论是在日活系中，还是在百年日本佳片中都很有代表性。

不一样，丙烯是CH2=CH-CH3聚丙烯是丙烯的高聚体聚丙烯（PP）作为热塑塑料聚合物在塑料领域内有十分广泛的应用，因所用催化剂和聚合工艺不同，所得聚合物性能，用途也不同。PP有很多有用的性能，但还缺乏固有的韧性，特别是在低于其玻璃化温度的条件下。然而，通过添加冲击改性剂，可以提高其抗冲击性能。 1. PP均聚物 聚丙烯（PP）作为热塑塑料聚合物于1957年开始商品化生产，是有规立构聚合物中的第一个。其历史意义更体现在，它一直是增长最快的主要热塑性塑料，2004年它的全国总产量达到300万吨。它在热塑性塑料领域内有十分广泛的应用，特别是在纤维和长丝、薄膜挤压、注塑加工等方面。 1.1 化学和性质 PP是在金属有机有规立构催化剂（Ziegler－Natta型），如δ-TiCl3-(C2H5)2AlCl或TiCl3-（C2H5)3Al（效率300～900克聚丙烯／克TiCl3）作用下，使丙烯单体在控制的温度和压力条件下合成的。因所用催化剂和聚合工艺不同，所得聚合物的分子结构有三种不同类型的立体化学结构，数量也不一样。这三种结构是指等规聚合物、间规聚合物和无规聚合物。在等规聚丙烯（最常见的商品形式）中，甲基原子团都处在聚合物骨架的同一侧，这一结构很容易形成结晶态。等规形式的结晶性赋予它良好的抗溶剂和抗热性能。在前十年期间所用的催化剂技术使非等规异构体的生成达到最少程度，消除了对无价值的无规组分进行分离的必要性，简化了生产步骤。生产聚丙烯的工艺主要有两种：一种是气相法；一种是液体丙烯淤浆法。此外，还有一些老式淤浆工艺装置在运行，它们采用一种液态饱和烃作为反应介质。 比较而言，高密度和低密度聚乙烯都有较高的密度，相当低的熔点和较低的弯曲模量即刚度。这些性能差异导致了最终用途不同。刚度和易定向性使聚丙烯均聚物适合制作各种纤维和用于延展带，而它们较高的耐热性使它们能用于制作硬的高压容器和器具及汽车的模塑部件。 影响聚丙烯均聚物的加工性能和物理性能的主要因素包括：分子量（通常用流速表示）；分子量分布（简称MWD）；有规立构性和助剂。聚丙烯平均分子量范围从约200 000到 600 000。分子量分布通常用聚合物的重均分子量（）与数均分子量（）的比值表示， 。该式又称为多分散性指数。 一个聚合物的分子量分布对它的加工性能和最终使用性能有举足轻重的影响。这是因为熔融态的聚丙烯对剪切敏感，即当施加的压力升高时，其表观粘度降低。分子量分布范围宽的聚丙烯比分布窄的更对剪切敏感，因而具有宽范围分子量分布的材料在注塑过程中更易于加工。某些特定的用途，特别是纤维，则要求窄范围的分子量分布。分子量分布与催化剂体系和聚合反应工艺都有关系。常用过氧化物在反应器后面的挤压过程进行化学裂解，使分子量分布范围变窄。这一过程称为控制流变学（CR）过程。 与聚乙烯相比较，等规聚丙烯其独特的分子结构及螺旋状晶体导致其分子链更易受光和热而氧化降解。在通常的加工和最终使用条件下，聚丙烯要经受无规的断链作用，导致分子量降低和流速升高。所有的商品级聚丙烯都含有稳定剂，以便在加工时保护材料，提供令人满意的最终使用性能。对于特别的用途，除了加抗氧剂和紫外线抑制剂外，还须加其它添加剂。例如：在薄膜配方中加入润滑剂和防粘剂，以减少摩擦系数并防止薄膜自身粘连。在包装材料中添加抗静电以消除静电荷。为了提高透明度或缩短模型周期，则需用成核剂。均聚物树脂通常按流速和最终用途分类。流速取决于平均分子量和分子量分布两者。某些特殊用途要求流速高达400分克／分钟，而普通商品均聚物的流速则在0.5-50分克／分钟的范围以内。流速通常是确定加工特性最主要的因素。 1.2 加工和应用 聚丙烯极好的流动性能和宽范围的流速，以及其它独特的聚合物特性相结合，使它具有优异的加工性能。较低的流速能满足挤压带、带状长丝和单丝等的加工要求，还能使成品有抗张强度和低延伸性，同时保持足够的横向完整性，使卷丝机导向装置上的劈裂和粉尘飞扬的情况达到最低程度。为了抵消它们特有的低横向强度和断裂倾向（原纤化），定向程度更高的薄膜到纤维产品，如：粗纤度纺织品、细绳和绳子，通常要求流速在7～20的范围内。含有发泡剂的装饰带条产品是由流速接近于10的聚丙烯挤压而成的，这样才能使熔体强度和定向能力达到适当的均衡。这种聚合物经中等程度的定向，能产生光滑的类似缎于一样的表面效果，产品有足够的横向强度可以延缓断裂。非织布和多丝产品的挤压需要一种低粘度、自由流动的材料，因此，流速极高的聚丙烯用于这些用途。 浇铸PP薄膜大量用于绘图艺术品方面。另外，薄膜可以双轴取向和热变定，使具有极好的机械性能和热性能，应用于各种性能层合材料和包装材料方面。使用管式水冷激工艺可以把PP加工成共挤出吹制薄膜以及单层薄膜。热成型用的挤塑片材要求使用低流速配方的材料，使具有足够的熔体强度。当使用PP挤塑型材时，较低的流速加工性能总是要好些。型材挤压通常限于较小的截面以便能用水急冷保证产品具有足够的韧度。PP还可以挤塑成管状产品，如饮料吸管和饮用水管。PP在线缆涂层方面也有用途。 在用量方面仅次于挤塑的注塑加工很适应聚丙烯的特性。PP良好的流动性能和强韧机械特性，被利用来生产许多种不同类型的具有内在的强韧机械性能的产品。良好的加工性能与极好的抗应力断裂性能产生了优良的模塑成型的密封罩。一般而言，低流速配方材料用于生产厚壁产品和那些要求韧性的产品。高流速的材料用于生产薄壁部件和要求快速加工的产品。 1.3 市场 PP均聚物可使用各种加工工艺，生产范围很宽的产品。 挤塑制品是消耗PP的最大市场，而纺织纤维和单丝又是其中最大的部分。长期以来，PP一直是制造纤维的主要原料，这是因为它的着色能力、耐磨损、耐化学品性能以及有利的经济条件。定向和非定向薄膜占据挤塑制品市场的第二大份额，并且是继续保持增长的领域。 接下来，注塑品是PP均聚物的第二大市场，包括容器、密封器、汽车方面的应用、家庭用品、玩具及其它许多消费品和工业方面的最终用途。许多吹塑容器选用聚丙烯，是因为它的良好的隔潮性能和足够的清沏度。鉴于对未来塑料制品的新需求，PP均聚物将继续保持增长。良好的经济方面的条件、良好的机械性能以及重量轻、着色能力强和易于加工等特性，将使PP继续成为本世纪众多应用领域的首选材料。 2.抗冲击型PP共聚物 PP有很多有用的性能，但还缺乏固有的韧性，特别是在低于其玻璃化温度的条件下.然而，通过添加冲击改性剂，可以提高其抗冲击性能。传统改良性为弹性体，通常为乙丙橡胶。普遍认为，遍布于半结晶态聚丙烯基体内的橡胶粒子，能在界面上形成许多应力集中点，防止局部形变，和断裂扩展。抗冲击改性剂一直是在共混时添加进去的，最近，弹性体组分的现场合成已经具有商业重要性。而且，正在宣传用一种新系列的冲击改性剂来代替乙丙橡胶，即Flexomer聚烯烃、Exact塑弹体和Insite聚合物。这些都是烯烃聚合物，它们填补了极低密度聚乙烯和传统乙丙弹性体之间的空白。 2.1 化学和性能 等规PP均聚物，是在Ziegler-Natta催化剂体系催化下，由丙烯聚合而成的。乙丙橡胶组分在一系列反应器中合成的，或是预先购买，然后在挤压机内与PP均聚物共混。生成的抗冲击聚丙烯经粒化后出售。现场生产的抗冲击PP共聚物，可以通过选用合适的催化剂组成及反应器条件，来精确地控制其重要的性能。催化剂组成和反应器条件决定基体树脂的结晶度、橡胶组分的组成和数量及总体分子量分布。 抗冲击PP是最轻的热塑性塑料之一，其密度低于1，每磅产品的价格低于PET、PBT、高抗冲击聚苯乙烯和ABS。按比容计，抗冲击PP的单位体积成本低于上述那些树脂和聚氯乙烯（PVC）。仅有HDPE在这方面堪与匹敌。抗冲击型PP通常在适中的温度下加工，范围为350～550°F。抗冲击聚丙烯共聚物具有广谱的熔体流动速率，通常范围为从小于1到约30。具有最高熔体流动速率的树脂，通常是由熔体流动速率较低的材料“减粘裂化”制得。也就是对从反应器出来后的材料进行一步反应，降低平均分子量，从而制得熔体流速更高的产品。抗冲击聚丙烯共聚物对化学品和环境应力断裂有很高的抵抗力。经处理后，材料可具备优良的悬臂梁式冲击强度和较低的加纳尔冲击性能。悬臂梁式冲击强度范围在0.5到大于15英尺·磅／英寸；在-40°F下，加纳尔冲击强度范围为15到300英寸·磅以上。 橡胶组分为聚丙烯提供了冲击强度，却使抗冲击聚丙烯相对于均聚物而言，降低了刚度和热变形温度。加填料的抗冲击聚丙烯共聚物能够忍受更高的温度而不变形。填料一般为玻璃纤维。云母、滑石和碳酸钙。这些聚合物的最终用户应该知道对每一种规格的产品，在不同的熔化强度、熔体流速、刚度和热变形温度之间需作出权衡。 2.2 用途 抗冲击聚丙烯的主要商业用途是用在汽车、家用品、器具中的注塑件。它的抗冲击能力、低密度、着色能力和加工性能使它成为理想的材料。具有较高熔体流速的中等抗冲击树脂品级有较高的流动性能，这个特点在注塑大型部件如：汽车面板时特别有用。 高抗冲击能力具有较低熔体流速的树脂（一般小于2），可以转化成抗穿刺性极好的薄膜，这种薄膜的抗冲击能力和耐蒸汽杀菌能力，适合做一次性医疗废品袋。挤压片材可以用热成型法加工成大而厚的部件，如：汽车工业中的护板和汽车车尾行李箱衬里。弹性体组分改良聚丙烯抗冲击性能的机理，在材料受冲击时，可诱导应力白化。大多数用途是以弹性组分在聚丙烯基体中的分散度为基础的。基于与此相反的概念，正在开发新型的保险杠。其结果是形成了一个分子复合结构。 注释 聚丙烯 丙烯的聚合物 英文名称polypropylene缩写PP均聚物 由一种单体聚合而成的聚合物称为均聚物。 高分子 高分子就是那些分子量特别大的物质。常见的分子,我们称它们为小分子,一般由几个或几十个原子组成，分子量也在几十到几百之间。如水分子的分子量为18、二氧化硫的分子量是44。高分子则不同，它的分子量至少要大于1万。高分子物质的分子一般由几千、几万甚至几十万个原子组成，它的分子量也就是几万、几十万、甚至以亿来计算。高分子的“高”就是指它的分子量高。 聚合物 高分子分为天然高分子和人工合成高分子，天然橡胶，棉花等都属于天然高分子。人工合成高分子主要包括：化学纤维、合成橡胶和合成树脂(塑料)，也称为三大合成材料。此外，大多数涂料和粘合剂的主要成分也是人工合成高分子。人工合成高分子又被称为聚合物(Polymer)。 如：聚丙烯、聚乙烯等。 共聚物 两种或两种以上的单体或单体与聚合物间进行的聚合称为共聚，共聚得到的产物即为共聚物。分嵌段共聚物、接枝共聚物、无规共聚物、有规共聚物等。

不少爱喝咖啡的人，或者是爱吃小零食的人，可能都会在食品包装标签上见过植脂末这个名字，植脂末又叫做奶精，主要是以氢化植物油为原料加工制作而成，在食品中应用十分广泛，常常添加在咖啡、蛋糕、饼干、巧克力、冰激凌以及饮料等食物中，主要用来替代奶制品，可以大大改善食品的口感，同时又可以降低生产成本，在食品工业中的应用已经有几十年的历史。氢化植物油的生产过程中会产生反式脂肪酸，这种物质对人体有较大危害，可以使人体血液中的低密度脂蛋白增加，高密度脂蛋白减少，诱发血管硬化，增加心脏病、脑血管意外的危险。美国哈佛大学医学院经过研究发现：反式脂肪酸摄入大大增加了患心脏病的风险，不但如此，它还会干扰必要脂肪酸的代谢，影响儿童的生长发育及神经系统健康，增加2型糖尿病的患病风险并导致女性不孕和罹患乳腺癌。氢化植物油在自然界是不存在的，也就是说在自然情况下，人体是无法吸收消化这种油脂的。食用后会对肝脏产生伤害，进而破坏人体细胞膜，造成细胞的缺陷，影响细胞未来的复制与再生，对人体的害处是显而易见的。所以，对于含有植脂末的食品，要尽量少吃，以避免植脂末造成的对人体的危害。

在刚使用Masonry的时候，会碰到需要将单独的图层Layer添加到View上，而CALayer是不可以调用Masonry方法的，这对于在使用Masonry的情况就比较尴尬，下面我们来直接用一种比较简单的解决办法，后边会简单讲一下原因。 我们可以通过获取View的frame来解决这一问题，而通过Masonry添加约束后是不会及时更新相对应的frame的。 这个时候我们可以通过layoutIfNeeded来调用layoutSubviews这个方法来解决，这么说可能有点蒙，举个例子看一下 这时我们看到当我们调用[self.view layoutIfNeeded]时，- (void)layoutSubviews方法被调用了，并且得到了约束后View的frame。 有的时候，会发现我们调用了layoutIfNeeded,但- (void)layoutSubviews方法却没有被调用，我们可以在调用layoutIfNeeded之前先调用一下setNeedsLayout 这样- (void)layoutSubviews方法一定会调用，下面来简单讲一下原因。 Masonry是对Autolayout的一个封装，当通过Autolayout对控件添加约束后，系统会调用layoutSubviews来对所有VIew更新frame，但我们通过Masonry对View添加完约束后不是马上就会调用layoutSubviews方法。 这时我们就可以调用layoutIfNeeded和setNeedsLayout方法来对layoutSubviews方法进行调用。但为什么有时只需要调用layoutIfNeeded而有时还要现调用一下setNeedsLayout呢，下面简单讲一下这两个方法 如果我们不管什么时候都想强制调用layoutSubviews方法的话就同时调用
