Scientists have known for decades that having measles (麻疹）suppresses kid"s immune systems for several weeks or months, leaving them ill-equipped to fight off pneumonia, bronchitis and other infections.Now a team of researchers has suggested that the measles vims may also leave a longer-lasting sort of “immune-amnesia” that makes it harder for people to stave off other illnesses for two years or more.That re-emphasizes the importance of vaccination (疫苗)，said biologist Michael Mina, lead author of a paper that was published in the journal Science.“There may be a long-lasting impact that you can"t undo if your child gets measles,M he said. “I hope this stu% can impress upon people the danger measles poses.”The rearchers used what Mina called “an unconventional approach" to search for the long-lasting immune system effects. Previous work in monkeys suggested that monkeys with the disease lost white blood cells their bodies had trained to fight off other illnes^s, leaving them more likely to be infected.To test if a similar thing may occur in humans, the group mined historical data to find out the relationship between measles incidence (发病率)and deaths from other infectious diseases.and deaths from infectious disease both before and after the introduction of the measles vaccine in the U.K. in the 1960s，Mina and the team saw a sort of shadow effect, where deaths from a variety of non-measles infectious diseases closely tracked measles incidence. The more measles in a population, the more deaths from other illnesses in the 28-month period that followed.“Really it didn"t matter what age gj*oup, what decade or what country, said Mina. “They all showed consistent results ... what we"re suggesting happens over the long term is that your immune system works fine，but it has forgotten what it previously learned.”Some researchers who were not involved in the work questioned whether the reductions in deaths as measles cases declined may have had more to do with improving nutrition and smaller family size than with prolonged immune suppression.Others thought the paper"s opinion of years-long suppression was seemingly reasonable but said they could not comment on the mathematical models the group used.To know for certain what was behind the effect the group saw, Mina agreed, scientists would need to look at immune cells and observe their behavior. He said he would like to push the work in a more traditional direction: back into the laboratory.

小题1:B小题2:A小题3:C小题4:C试题分析：本文叙述了科学家的一种想象，在地球的上方放一面60英里宽的镜子，它可以用来为城市延长照明的时间，它的能量可以融化霜冻，以防霜冻冻坏庄稼。还可以融化冰山，能够改变云的运动以便在需要雨的地方降雨。小题1:细节理解题。根据Itmightbesixtymileswide.故选B。小题2:细节理解题。根据Itwouldbeusedtocatchtherays(光线)ofthesun.Itwoulddirectthesun"sraysupontheearthasachildmightdotomakesunlightdanceonthewallwithahandmirror.镜子能反射阳光，故选A。小题3:细节理解题。根据Theycouldlightupcitiesbynight.故选C。小题4:细节理解题。根据Scientistswouldliketoplaceahugemirrorinspaceabovetheearth.Itmightbesixtymileswide.这是科学家的想象出来的，故选C。点评：细节题为阅读考题的重头戏，所占比例高达80%，相对而言较简单，因为这类题虽然要求理解准确，但基本上限于字面意义的理解，范围也限于局部，因此是我们可望得高分的部分。细节题绝大部分体现“中心思想是解”这一原理。本文都是细节理解题，在文中比较容易找到答案。

小题1:C小题2:B小题3:C小题4:A 试题分析：文章是一篇说明文，说明全世界不同地区的人，有不同的饮食习惯，不论怎样，最重要存在两大问题，一是消除饥饿，二是吃出健康。小题1:推理判断题。由文章第一段科学家列出的每天应吃的食物种类，包括蔬菜、水果、谷物，鱼肉蛋、奶、坚果，要均衡饮食，可推断出C答案中包含的种类多，所以选C。小题2:细节理解题。由此句It doesn"t matter whether food is eaten raw or cooked,“食物是生吃还是熟吃都没关系。”可知raw和cooked应该是对应词，cooked在此的意思是，做熟了的，所以raw是“生的”。故选B。小题3:细节理解题。由第二段最后一句话The important thing is what you eat every day.“最重要的事情是你每天吃什么。” 可知选C。小题4:主旨大意题。由第二段第四行It doesn"t matter whether food is eaten raw or cooked, cool or hot.，推出B不正确；由最后一段第二句话The first is to find some ways to feed the world"s population so that no one in hungry.可知C不对，再根据全文的中心意思，故选A。

For years scientists have been worried about the effects of air pollution on the earth"s natural conditions. Some believe the air inside many houses may be more dangerous than the air outside. It may be one hundred times worse.Indoor air pollution can cause a person to feel tired, to suffer eye pain, headache and other problems. Some pollutants（污染物）can cause breathing disorders, diseases of blood and even cancer. Most scientists agree that every modern house has some kind of indoor pollution.People have paid more attention to the problem now. It is true that when builders began making houses and offices they did not waste energy. To do this they build buildings that limited the flow of air between inside and outside. They also began using man-made building materials. These materials are now known to let out harmful gases.As the problem became more serious, scientists began searching for a way to deal with it. They discovered a natural pollution control system for building—green plants. Scientists do not really know how plants control air pollution. They believe that a plant"s leaves absorb or take in the pollutants. In exchange the plant lets out oxygen through its leaves and tiny organizations on its roots. Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square meters of space. Studies of different plants show that each absorbs different chemicals. So the most effective way to clean the air is to use different kinds of plants. Having green plants inside your house can make it a prettier and more healthy place.多年来科学家们一直担心的影响,空气污染对地球的自然条件。一些人认为许多房屋内空气比外面的空气可能更危险。这可能更糟一百倍。室内空气污染会使人感到疲劳,出现眼痛、头痛和其他问题。一些污染物(污染物)可导致呼吸疾病、血液疾病,甚至癌症。大多数科学家一致认为每个现代的房子都有某种形式的室内污染。现在人们更加关注的问题。的确,当建筑工人开始房屋和办公室他们不浪费能源。为此他们建造建筑物,有限的内部和外部之间的空气流动。他们也开始使用的人造建筑材料。这些材料目前已知放出有害气体。问题变得更加严重,科学家们开始寻找一种方式来解决它。他们发现了一个天然绿色建筑工厂的污染控制系统。科学家不知道植物如何控制空气污染。他们认为,植物的叶子吸收或污染物。在交换植物让氧气通过它的叶子和小组织在其根源。科学家建议,所有的建筑都应该有一个大的植物或一些小植物内每9平方米的空间。不同的植物的研究显示,每吸收不同的化学物质。所以清洁空气的最有效的方法是使用不同类型的植物。有绿色植物在你的房子可以使它成为一个更漂亮,更健康的地方。

Scientists recently discovered that pictures on cave walls at Creswell Crags are the oldest known in Great Britain. But they didn"t find out in the usual way.Archaeologists often date cave art with a process called radiocarbon dating. The technique can measure the age of carbon found in charcoal（木炭）drawings or painted pictures. Carbon is an element found in many things, including charcoal and even people. But in this case, there was no paint or charcoal to test. People carved the pictures of animals and figures into the rock using stone tools. The scientists had an “aha!” moment when they noticed small rocks stuck to the top of the drawings. The small rocks must have formed after the drawings were made.“It is rare to be able to scientifically date rock art,” said Alistair Pike, an archaeological scientist at Britain"s University of Bristol. “We were very fortunate that some of the engravings were covered by stalagmites（石笋）.When a test proved that the stalagmites formed 12,800 years ago, the scientists knew the art underneath them had to be at least that old. And some of the animals shown, like the European bison, are now extinct--another tip-off that the art is quite old.The artists came to Creswell Crags, This place is one of the farthest points north reached by our ancient ancestors during the Ice Age. At that time, much of the North Sea was dry, so people could move about more easily.Some tools and bones found there are 13,000 to 15,000 years old. They show that the travelers hunted horses, reindeer, and arctic hare. Their artwork is similar to art in France and Germany. It tells scientists that the Creswell Crags artists must have had a close connection to peoples several thousand kilometers away－another important clue to understanding how humans spread out across the world.62. Which of the following can be used as the best title of the passage?A. Cave Art About Animals Is Most BeautifulB. Cave Art Found in an Unusual WayC. Cave Art Turns Out to Be Britain"s OldestD. Cave Art in Britain63. The underlined word “archaeologists” in this passage probably means people ________.A. who study things left behind by people in the pastB. who have rich experience in paintingC. who are interested in wild animalsD. who are good at using stone tools64. Why do scientists say the art is quite old?A. The art was carved into stone with stone tools.B. The animals carved in the stone are beautiful.C. The cave is one of the farthest point in the world.D. Some pictures were covered by stalagmites more than 10,000 years old.65. By studying the cave art, scientists know something about _________.A. how ancient people crossed the North SeaB. why some of the animals have died outC. how humans spread out across the worldD. what kind of animals people hunt at that time答案 CAD

　　题目找不到，但是找到原文。　　Scientists hope that if we can discover how the brain works, the better use wewill be able to put it to. For example, how do we learn language? Man differs most from all the other animals in his ability to learn and use language but we still do not know exactly how this is dine. Some children learn to speak and read and write when they are very young compared to average children. But scientists are not sure why this happens. They are trying to find out whether there is something about the way we teach language to children which in fact prevents children from learning sooner. Earlier scientists thought that during a man"s lifetime the power of his brain decreased. But it is now thought thatthis is not so. As long as the brain is given plenty of exercise it keeps its power. It has been found that an old person who has always been mentally active has a quicker mind than a young person who has done only physical work.

It is reported that the activity will last a week. The purpose of this activity is mainly through the expert panel and a series of experience activities to let the youth feel the charming of science. In the spot, the scientists share the knowledge of astronomy in an easy way and the youth asking questions actively. After the activity, the youth said that this activity is very meaningful and widen their vision. The activity also inspire them to study harder in order to bee a scientist in the future. Besides, they said that the informative activity also support them a meaningful holiday. 　　科学家英语作文篇2 　　There is a scale in the picture with some nature factors on it"s left tray and some nurture factors on it"s right tray. And in the top of the picture, “The making of a successful scientist—nature or nurture?” reads 　　We can infer from that what counts more to make a successful scientist is nature but not nurture. 　　As we all know, interest leads to success. So, I think if a scientist is successful in one field, he or she must be much more interested in the field than others. Let"s take Einstein for example, if he were not so interested in physics, he would not have been so successful in its field. Thus, we can say the making of a successful scientist is nature. 　　However, the only nature is not enough, the nurture is also absolutely necessary. First, you must be in favor of the field, next, you must learn the knowledge connected with it, only in this way can you keep in up with the scientists who are researching in it and transcend them. During the course, you must learn from others, and so on. Finally you are likely to be a scientist. Imagine it, someone is very very interested in math, but he even doesn"t know what we can get if we add 1 to 1. Do you really think he can be a scientist, a successful scientist? 　　In a word, to make a successful scientist, nature and nurture are both important. 　　科学家英语作文篇3 　　It is generally agreed that society benefits from the work of its members. pare the contributions of artists to society with the 　　contributions of scientists to society. Which type of contribution do you think is valued more by your society? Give specific reasons to support your answer. 　　Artists and scientists both make valuable contributions to our society. It may seem sometimes that artists are more valued. That"s because those artists who are famous make a lot of money. However, they are relatively few. The fact is that scientists are more valued. They get more respect from society for the work they do. 　　Artists reflect their times and their culture. A painter or a writer shows us in pictures and words what we"re like as a people. They record our culture for future generations. Actors and other performers, like singers and dancers, entertain us. They take our minds off our troubles, and 　　remind us how beautiful and exciting our imaginations can be. Artists also help keep their societies mentally and emotionally healthy. For example, children that participate in the arts, such as painting or music, in school do 　　better in their other studies. Art of all types is necessary to the human spirit. 　　The contributions scientists make to society are more obvious. They include the cars we drive, the puters we use at home and at work, and the appliances that help us cook our meals and clean our houses. All of these e from the ideas and hard work of scientists. Because of scientific discoveries, we"re living longer and more healthful lives. 　　Scientists also contribute to the arts. Movies are the result of science. So are television, radio, and the recording of music on CDs. 　　Generally, scientists don"t make as much money as famous artists like film stars, opera singers or successful painters. However, our society gives them more respect, and they generally make a good living. 　　Scientists are considered to be serious professionals, while artists are sometimes viewed as flaky, irresponsible people. So overall, I"d have to conclude that we value scientists more. 》》》》下一页更多精彩“科学家英语写作范文”

Researchers at the University of California found that exposure to the cold increases levels of a protein that helps form brown fat—the type of fat that produces heat and keeps us warm. Brown fat burns energy, ___42____helps us lose weight. White fat stores extra energy, which results___43___weight gain. The researchers said that because air conditioning and heating give us constant,___44_____(comfort) temperatures, our body"s need for brown fat has decreased. They found that: "Outdoor workers in northern Finland who ___45____(expose) to cold temperature have ____46___ significant amount of brown fat when ___47___(compare) to same-aged indoor workers."The research was conducted on two different control groups of mice. ____48_____ group was injected with the protein that helps create brown fat. This group later gained 30% less weight after both groups were fed high-fat diets. The researchers say this could be good news in the fight against obesity（肥胖症）.

Some people immediately think of intelligence, IQ, to a class of things, because to reveal the mysteries of nature, to capture the fortress of science, near the sea to catch turtle, shoot for the moon...... Must, have great magic power, prowess, if there is no clever mind, not keen powers of observation, a quality of the imagination, butdon"t forget the memory, and no outstanding imagination and rigorous reasoning ability, is absolutely out of the question. To be aware of, this point of view, this argumentalthough mainly from non scientific workers, but in societyhas a great market. So, what actually is? Let us listen toscientists their sound.The Belgian cell biologists, biochemists Dedive (C.deDuve) said: "usually the scientists described asknowledgeable people, this idea is a grain of truth. In order to do scientific research, at least you have to accept a science training...... We need to learn moreknowledge, accept more exercise....... But, "know everything" is not sufficient to be considered as artcollectors conditions -- scientists is not necessarily artist.The true measure of scientists, is to see whether it cangenerate new knowledge, or more precisely, to see whether it has engaged in scientific needsunderstanding." Please note: this "will", "whether" is crucial, because then he also said: "most of us lack ofinsight into the mysteries of the universe"s extraordinarytalent, but just do not only do what little one can to helpscience building work...... In this case, a person is engaged in science or a scientist is mainly driven by curiosity. When you face the fact, the phenomenon ofstrange, always be overcome by one"s feelings to explor it." Actually, Dedive hinted that everyone, curiosity uorperhaps solve "will", "whether" key, because there is noscientific curiosity, the extraordinary wisdom and understanding may be lost.Bardeen is a famous physicist two times won the Nobel Prize, people called him a remarkable talent of many ages. He gave the impression that the people around,have a curiosity about the physics problems as childrenthings of interest, it is the curiosity that he is full of passion. Bardeen likes physics and math very much, andsoon learn to focus on the problem, and hard work are often brought him great spiritual return. So, curiositybrings passion was the cause of his miracles. In view of this, Gopnik (Alison Gopnik), the scientists compared to the growing of children, Gardiner (Howard Gardner) thenecessary for creative work attachment with the childcuriosity about the outside world around together.Moreover, such a point of view we Einstein in the autobiography also can see.Admittedly, intelligent, IQ intelligence factor plays an important role in scientific research. However, if the stressover the head, as if also does not accord with the facts,because many famous scientists in the history, not onlywhen reading performance is not outstanding, but at the time of the scientific research consciousness to some oftheir own lack of. In "Memoirs of Darwin" one book, weread as follows: "memories of him in a clear and conciseexpression of their ideas, I still as usual, very difficult; thedifficult to me a lot of time consumption; but in this regard will have a compensation benefits, it is: I have to thinklong and intently to every sentence, so I can be ininference, as well as in their own and other people"sobservations, and find out the mistakes and oversights.""I have no understanding of extremely sharp, not very witty: a few intelligent people, such as Huxley, has thegood quality. Therefore, I am just a clumsy critic: I firstread an article or a book, usually to praise...... I follow alengthy abstract thinking route -- this ability, there is a limit to me; therefore, I am in metaphysics and mathematics did not get any achievement. My memory,extensive range, but vague...... My memory is in some ways a poor: any date, or a sentence, in a few days, will be forgotten by me."So, what is the most important qualities of scientists? To sum up, shall not IQ, EQ, is unlikely to be theperseverance, courage, the pursuit of a kind of quality.The only way out, is also looking for. In the variousqualities of human one one excluded, in recent years is quite considerable in scientists interviewed two words in the report: "curiosity" and "interest" has attracted myattention. The butcher looked for his knife and it was in his mouth. Mr. Bian Yulin in a popular science article in paragraph confirmed and strengthened the author:Gamow, science is the source of human pursuit fornature and own understanding. Scientists the most important quality is the most common curiosity. Gamow wrote: "some people say: "curiosity can kill a cat", but I say: "curiosity creates a scientist.""These words have two non identical not. The first relates to what is curiosity; second points that curiosity very ordinary, but it can make a scientist. To get to the bottom of this two points and reach a consensus, not only toanswer "what is the most important quality?" Problems,but also of great significance. What is the curiosity? Whyare scientists the most important quality? Length of be confined to, the following simple reasoning to prove this assertion: embarked on the road of scientific researchpeople, curiosity will interest; interest will be good thinking; good thinking will be found, that can create theinvention. The interlocking logic chain is a true portrayal of scientific research activities, but in the field of scientific research, and its source -- scientists curious, as the most important quality is tenable. It not only for the numerousscientific facts have proved repeatedly, but did produce agreat scientist.

蜱(pí)也叫壁虱，俗称草扒子、草鳖子、狗豆子、牛虱、扁虱、草蜱虫。蜱虫属于寄螨目、蜱总科。成虫在躯体背面有壳质化较强的盾板，通称为硬蜱，属硬蜱科，主要种类有全沟硬蜱、草原革蜱、亚东离眼蜱等；无盾板的，通称为软蜱，属软蜱科，软蜱寿命可达15~25年。全世界现已发现蜱约800多种，硬蜱科约 700多种，软蜱科约150种，纳蜱科1种。中国已记录的硬蜱科约100种，软蜱科10种。蜱是许多种脊椎动物体表的暂时性寄生虫，常常寄宿于牛、羊、狗、猫、老鼠等牲畜动物皮毛间，也蛰伏在浅山丘陵的草丛、植物上，爱躲在茶叶背面。蜱虫本身并无毒素，但它能携带和传播病毒，是一些人兽共患病的传播媒介和贮存宿主。目前中国已知蜱虫可携带83种病毒、14种细菌、17种回归热螺旋体、32种原虫等。多种病原体可引发“发热伴血小板减少综合征”，包括无形体感染和病毒感染等。不吸血时，小的蜱如干瘪绿豆般大小，也有极细如小米粒的；吸饱血液后，饱满的如黄豆大小，大的可达指甲盖大。蜱虫携带的病毒，叮咬人时能侵染人的末梢血中性粒细胞，引起发热伴人体血小板、白细胞锐减和多脏器功能损害。目前，还从有的病人检测物中发现布尼亚病毒（Bunia virus）。布尼亚病毒是一种RNA（RiboNucleic Acid 核糖核酸）病毒。像引起流行性出血热汗含钾病毒，引起新疆出血热，（即克里米亚—刚果出血热 Crimean-Congo hemorrhagic fever）病毒，都是布尼亚病毒。到现在为止，病毒唑等抗病毒药已证明对布尼亚病毒类疗效确切，但目前真正的有效治疗该病毒的药物很少。布尼亚病毒自然感染多见于脊椎动物和节肢动物，如蚊、蜱、白蛉等，可感染小鼠，并能在一些哺乳类、鸟类和蚊细胞培养中生长，对人可引起类似流感或登革热的疾病、出血热，立夫特谷热和克里米亚—刚果出血热及脑炎，加利福尼亚脑炎。有蚊媒、蜱媒、白蛉媒3种传播类型。有些病毒在其节肢动物媒介中，可经卵、交配或胚胎期传播。人被蜱虫叮咬后，患者大多起病急而重，主要症状为高烧 40℃以上、伴全身不适、头痛、 眼眶痛、腰痛乏力、肌肉酸痛，以及畏寒、恶心、呕吐、腹泻、厌食、精神萎靡等。患者的面颊、鼻、颈部、前胸、上臂等处发红长红疹或有出血点，重者便血、尿血（酱油尿）、大小便失禁、 尿内出现膜状物并危及心、肺、脾、胃、肾、脑垂体、肾上腺等多处脏器，出现如败血症、中毒性休克、中毒性心肌炎、急性肾衰、呼吸窘迫综合症、有些还有广泛的微血栓形成，极易出现严重的水电解质酸碱平衡紊乱。发生在幼儿身上，表现为急性上行性麻痹，可因呼吸衰竭致死。患病的初期症状类似感冒，潜伏期可达1-2周（平均9天），易被误诊。蜱叮咬人时分泌一种麻醉抗凝剂，让人的血液不凝固以便顺畅吸血，它将头埋在皮肤内吸血，发散的抗凝剂是一种对人体有害的神经毒素，毒物由此注入人体内，唾液中的毒素可导致被叮咬者运动性纤维的传导障碍，引起上行性肌肉麻痹现象，可导致呼吸衰竭而死亡，称为蜱瘫痪。被蜱虫咬不能立刻打死虫子，因蜱虫在受到外界刺激后，会通过爪分泌更多毒素。钻入人体的头部需及时取出， 蜱虫的头钻入皮肤后，头有锯齿状倒钩刺越拉越紧，不妥善取出，易将头留在皮肤内继续感染，导致病毒扩散，轻者，数年后遇阴雨天气，便瘙痒难忍。重者，高烧不退、全身瘫痪无力不能自行站立、深度昏迷、抽搐，出现心力衰竭、肺肿、可引发森林脑炎（Russian spring-summer encephalitis）、Q热（Q Fever ）、北亚蜱传斑疹伤寒（North-Asian tick-borne typhus）、新疆出血热、莱姆病（Lyme Disease）、蜱媒回归热(tick-borne relapsing fever) 又称地方性回归热等细菌性疾病和自发性肾破裂严重并发症， 发病后第6～9天死亡。蜱叮咬携带病原体的宿主动物后，再叮咬人体时可随之进入人体引起无形体病，或称“发热伴血小板减少综合症” ，主要症状为持续高热，可达40℃以上，全身不适、乏力、头痛、肌肉酸痛，以及恶心、呕吐、厌食、腹泻等。部分患者伴有咳嗽、咽痛。体格检查可见相对缓脉，少数病人可有浅表淋巴结肿大及皮疹。可伴有心、肝、肾等多脏器功能损害状况。无形体病属传染病，人对此病普遍易感，应对病人的血液、分泌物、排泄物及被其污染的环境和物品，进行消毒处理。与危重患者有密切接触、直接接触病人血液或带菌动物的血液等体液的医务人员或其陪护者，如不注意防护，可导致疾病传播和交叉感染。“无形体病”并不是一种新病，最早于1994年在美国被发现。无形体病的全称为“人粒细胞无形体病”(Human granulocytic anaplasmosis, HGA)，最初，病原体被认为是查菲埃立克体，后来发现病原体是嗜吞噬细胞无形体。 无形体病是人兽共患病，上世纪90年代，美国和欧洲就都有过报道。美国每年报告的病例约600-800人，法国、英国、德国、澳大利亚、意大利及韩国等国家也多有发病。由于病原体的分离和鉴别难度很大，迄今为止，只有美国和欧洲的一个国家从蜱虫咬伤患者体内分离出病原体，2001年将病原体定名为“无形体”。 所谓“无形体”，是一种寄生于细胞内的寄生菌，主要通过蜱虫叮咬传播。2006年中国安徽省首次发现该病。随后在山东、河南、湖北、北京等地也有该病病例报告。根据卫生部通报，截至2009年9月，全国报告人粒细胞无形体病例92例，死亡3人。近年来，湖北、河南、山东、黑龙江、内蒙古、新疆、天津、海南、四川、云南、江苏，都出现过病例。截至2010年9月，中国有12个省份发现疑似无形体病例，这些地区的特点都是山区或水域丰富的地方，全国至少已有33人因蜱虫叮咬染病死亡。目前，对蜱虫病尚未确定病原体。蜱传疾病是一种常见疾病，以前就有，此次特点为传播了新的病原体。无形体病发病时间主要集中在5－10月，其中6－8月为发病高峰，发病年龄以40～70岁居多。老年患者、免疫缺陷患者及进行激素治疗者感染本病后病情多较危重，尤其是激素类药物会加速病原体在人体内的繁衍，导致病情恶化，应慎用！为防控无形体病，应少在草地、树林等环境长时间坐卧，避免被蜱叮咬。进入有蜱地区要穿防护服，扎紧裤脚、袖口和领口，可在领口、袖口、裤脚等处喷涂0.2％敌百虫水溶液或0.5％拟除虫菊乙醇溶液。 尤其是野外垂钓者，要扎紧裤管。蜱虫较喜欢在山区的针叶林活动，尤其是云冷杉林和油松林。旅游者入山，要穿长衣长裤，勿轻易入杂草丛中 。村民下田，不管是晴天还是阴天，都要穿高筒雨靴，扎紧裤脚和上衣袖口。颈、手等外露部位要涂驱避剂，如避蚊胺（DEET）、避蚊酮、邻苯二甲酸二甲酯、前胡挥发油，或用驱避剂喷涂衣服。对野外游离蜱可采用局部火烧，对蜱类栖息及越冬场所喷洒倍硫磷、毒死蜱、顺式氯氰菊酯等，对附着在畜舍、畜体上的蜱，可采用敌草隆、茅草枯、毒莠定等杀虫剂进行灭除。在林区使用烟雾剂灭蜱。杀虫剂中加入蜱的性外激素与聚集激素可诱蜱而提高杀灭效果。绿色环保治蜱方法：白僵菌、绿僵菌及烟曲霉菌等对蜱有致死作用。跳小蜂可产卵于蜱体内，待发育为成虫可致蜱死亡。禽畜的窝舍应远离民房，并经常打扫干净，墙面缝隙也要填平。禽畜的窝舍和活动处所要喷药处理。为防止蜱虫侵入室内，可将松节油、蓖麻油黏胶涂在20厘米宽的长纸条上，放置于靠近门窗附近的墙基地面，对蜱进行粘杀。 在公园草坪或小区绿地遛狗时应注意，遛狗之前，最好喷一点抗虫喷剂，常规的即可，长毛犬较易招蜱虫，会将其带入家中。蜱虫主要是叮咬狗狗的3个部位，一是耳孔；二是脚趾间，掰开狗狗的两个脚趾，可看到密密麻麻的蜱虫吸在红肿的皮肉间；三是耳朵外沿，这里的蜱虫特别细小，但数量多得惊人，寄生于狗狗身上的硬蜱主要有血红扇头蜱、二棘血蜱、长角血蜱、草原革蜱和微小牛蜱等，常见的是羊蜱。 软蜱吸血，大量寄生时能使狗狗消瘦，贫血，衰弱，甚至造成死亡。软蜱还能传播各种犬的疾病，如焦虫病、布氏杆菌病、钩端螺旋体病和野兔热病等。尽量避免抱猫、狗狗等宠物上床睡觉的行为 。 爱犬如被蜱虫叮咬，可用虱癞螨虫一喷净或灭害灵一天喷一次，连续几天，或使用专门杀灭蜱虫的福来恩滴剂或安万克滴剂，用福来恩滴剂的时候前后48小时不要给狗狗洗澡，只需一支滴在狗狗的颈部，被皮肤吸收后就会起效，寄生虫会在24小时内清除，并且80天之内不会再有虫虫光顾！简单！安全！适用于4周龄以上的幼犬及怀孕哺乳期的母犬。 也可采用多个国家使用的苏云金杆菌微生物制剂--内晶菌灵，涂洒于犬的体表，能使蜱死亡率达70~90％。它在内晶芽孢菌细胞内可形成一种毒性很强的结晶，称为内毒素。当毒素随同食物进入蜱的肠道后，破坏其肠道内pH值的稳定性，使其消化紊乱，停止采食，虫体麻痹，进而使虫体内共生的其他微生物具有致病力，使其染病死亡。此外，定期给宠物药浴杀蜱可有效降低病毒传播效果。蜱易附着在人体的头皮、腰部、腋窝、肚脐眼、腹股沟及脚踝下方等部位。如果叮在耳根下、胳肢窝或裆部，毒性很易扩散，发起病来较难医治。发现蜱附着在身体上， 可用氯仿、乙醚、酒精、煤油、松节油、旱烟油涂在蜱虫的头部，或在蜱虫旁点蚊香，数分钟后蜱虫被“麻醉”，就自行松口;或用液体石蜡、甘油厚涂蜱虫的头部，使其窒息松口。然后立即用镊子等工具将蜱除去，不要直接用手将蜱摘除或用手指将蜱捏碎。如头部口器断入皮内应尽快采取手术方式取出，如能在24小时内拔除，感染的比率约三成，若超过48小时，感染率100%。伤口周围可用0.5％普鲁卡因局部消毒。出现全身中毒症状时使用抗组胺药和皮质激素甲基强地松龙救治。同时，一旦出现疑似体征，要立即就医，应主动将相关被叮咬的情况告知医生。 疫区的变异蜱已成为一种很危险的毒虫，但就如同蚊子一样，明知道它会传播疾病，人们现在却无法将它们灭绝。对早期被蜱虫叮咬病人不细心鉴别，很容易误以为是“感冒”，白细胞减少、血小板降低、肝酶升高是感染无形体病菌的几个显著特征。在就诊时，一定要告诉医生被虫叮咬过，一般在叮咬处会局部充血、水肿，有圆形的焦痂。通常，四环素类多西环素（强力霉素）、喹诺酮类左氧氟沙星和利福平为治疗无形体病的有效药物。治疗疗程不少于7天。一般用至退热后至少3天，或白细胞及血小板计数回升，各种酶学指标基本正常，症状完全改善，最后可完全治愈。早发现、早诊断、早隔离、早治疗，救治及时，病情明确，是染病后生存的关键。此病重在早期的发现，防止误诊!SO,咬你的虫虫不蜱虫。。。。不会有事

外汇是货币行政当局(中央银行、货币管理机构、外汇平准基金及财政部)以银行存款、财政部库券、长短期政府证券等形式保有的在国际收支逆差时可以使用的债权。包括外国货币、外币存款、外币有价证券(政府公债、国库券、公司债券、股票等)、外币支付凭证(票据、银行存款凭证、邮政储蓄凭证等)。截至2015年，中国位居世界各国政府外汇储备排名第一。但美国、日本、德国等国有大量民间外汇储备，国家整体外汇储备远高于中国。
