英语作文clever.and.foolish

Is the servant clever or foolish? This is an old story. It was first told long ago. A rich man wanted to make a journey to another town. He was a businessman. He wanted to take things to sell. He also wanted to take some gold to buy some things with. He decided to take ten servants with him. They would carry the things to sell and the food to eat on the journey. He was a kind man. He said to one of his servants, "You are the smallest, the thinnest and the weakest of all my servants. You cannot carry a heavy load. You may choose the lightest load to carry." The servant thanked his master. He pointed to the biggest load. This was bread for them to eat on the journey. "You are foolish," said his master. "That is the biggest and heaviest load." But the servant lifted up the load cheerfully and the journey began. They walked for four hours. Then they stopped for a rest. They all ate some of the bread. Then there was less bread for the servant to carry. The servant"s load grew smaller and lighter every day. At the end of the journey, the smallest servant had nothing to carry.

有关于北极概况的英文介绍

Climate change has led to a rapid melting of permanent ice in the Arctic. According to the latest research, in September 2011, the total area covered by ice in the Arctic Ocean had decreased by 40 percent compared to 1979. Based on calculations by scientists, the ice in the Arctic Ocean is estimated to disappear completely by the middle of this century. This means the once ice-covered area will change into a sea where ships can come and go freely without icebreakers. This revelation tells the economic value of the North Pole. New navigation routes linking East Asia, Europe and North America will be opened, allowing for quick routes for maritime transport linking the three regions. According to the exploration and evaluation conducted during the United States Geological Survey in 2008, the North Pole has 30 percent of the world"s undiscovered natural gas and 13 percent of the world"s undiscovered oil. All these resources are concentrated in the offshore continental shelf region and suitable for exploration. Scientists are worried that a melting North Pole will bring a series of disastrous effects to the Earth. In the global climate system, the North Pole and the South Pole are the two switches that control the ocean currents and the atmosphere. Once destroyed, disasters beyond imagination will occur. Therefore, how to explore the North Pole? How to protect it? How to distribute the resources? All these questions make the North Pole a question beyond a regional affair and a matter of international concern. Salary Increase For Public Servants Beijing Youth Daily January 21 In the latest session of Guangdong Provincial People"s Congress, some deputies from Shenzhen, Guangdong Province, called for a salary raise for public servants. They claimed public servants are paid less than enterprise employees. The comparison is too simple to be credible. In the business sector, employees" salaries are decided by the market. If the market goes into recession, the pay of enterprise employees will fall. But salaries for public servants are paid by governments, which are steadier than industries. People think public servants are well paid and have opportunities to receive “grey income.” In fact, this is a misunderstanding. The salaries of most public servants are meager. Despite low pay, public servants have better welfare, such as insurance and pensions. Public servants don"t need to pay endowment insurance. Moreover, after retirement their pension payments are higher than other people, and governments manage to offer officials houses. With the skyrocketing housing prices in China, this is a major form of welfare. That is why so many young graduates rush to become public servants every year. 来源:Beijing Review

中英文阅读《渔夫和他的妻子》(2)

  Then the man went home, and when he arrived there, the palace had become much larger, with a tall tower and magnificent decorations. Sentries stood outside the door, and there were so many soldiers, and drums, and trumpets. When he went inside everything was of pure marble and gold with velvet covers and large golden tassels. Then the doors to the great hall opened up, and there was the entire court. His wife was sitting on a high throne of gold and diamonds. She was wearing a large golden crown, and in her hand was a scepter of pure gold and precious stones. On either side of her there stood a line of maids-in-waiting, each one a head shorter than the other.渔夫於是回家去了。来到宫前时,他发现宫殿大了许多,增加了一座高塔,塔身上有漂亮的雕饰。一排警卫守卫在宫殿门口,附近还有许多士兵,门前还有一支乐队,敲着锣打着鼓。他走进宫殿,只见样样东西都是金子和大理石做成的;桌椅上铺着天鹅绒,垂挂着很大的金流苏。一道道的门忽地打开了,整座王宫处处体现着富丽堂皇。他的老婆就坐在镶嵌着无数钻石的高大的金宝座上,头戴一顶宽大的金冠,手握一根用纯金和宝石做成的"王仗。在宝座的两旁,六名宫女一字排开,一个比另一个矮一头   "Oh, wife, are you now king?" 。   渔夫走上前去对她说:「喂,老婆,你现在真的当上了国王吗?」   "Yes," she said, "now I am king."   「是的,」妻子回答说,「咱现在就是国王啦。」   He stood and looked at her, and after thus looking at her for a while he said, "Wife, it is very nice that you are king. Now we don"t have to wish for anything else." 他站在那里上上下下地打量着妻子,过了一会儿说:「哎,老婆,如今你当了国王,多么称心如意啊,往后咱们就不用再要甚么了吧?」   "No, husband," she said, becoming restless. "Time is on my hands. I cannot stand it any longer. Go to the flounder. I am king, but now I must become emperor." 「当家的,那可不行,」妻子回答说,情绪开始烦躁起来,「我已经感到无聊得很,再也无法忍受了。快去找比目鱼,告诉他说我要当皇帝。」   "Oh, wife" said the man, "Why do you want to become emperor?"   「哎呀,老婆,」丈夫说,「你干嘛要当皇帝呢?」   "Husband," she said, "go to the flounder. I want to be emperor."   「当家的,」妻子说,「快去找比目鱼。说我要当皇帝。」   "Oh, wife," said the man, "he cannot make you emperor. I cannot tell the flounder to do that. There is only one emperor in the realm. The flounder cannot make you emperor. He cannot do that."  「哎,老婆,」丈夫回答说,「比目鱼没法使你当皇帝,我也不想对他提出这个愿望。整个帝国就一个皇帝呀,比目鱼哪能随便使谁当皇帝呢?他确实不能。」   "What!" said the woman. "I am king, and you are my husband. Are you going? Go there immediately. If he can make me king then he can make me emperor. I want to be and have to be emperor. Go there immediately." 「你说甚么!」妻子大声喝道,「我是国王,你不过是我的丈夫而已。你去不去?给我马上去!他既然可以使我当上国王,他也能使我当皇帝。我一定一定要当皇帝,马上给我去!   So he had to go. As he went on his way the frightened man thought to himself, "This is not going to end well. To ask to be emperor is shameful. The flounder is going to get tired of this."  渔夫不得不去了。他走在路上时,心里感到非常害怕,边走边想,「这不会有好下场的。要当皇帝!脸皮真是太厚啦! 到头来,比目鱼就会恼怒啦。」   With that he arrived at the sea. The water was all black and dense and boiling up from within. A strong wind blew over him that curdled the water. He stood there and said:  他就这样一边想着一边走,来到了海边。只见海水一片墨黑,混浊不清,不仅汹涌翻腾,泡沫飞溅,而且旋风阵阵,令渔夫感到心惊胆战。不过,他还是站在海岸上说:   Mandje! Mandje! Timpe Te! Flounder, flounder, in the sea! My wife, my wife Ilsebill, Wants not, wants not, what I will「比目鱼啊,你在大海里,恳请你好好听我说仔细,我捉你放你没提愿望,老婆对此却不饶又不依。」   "What does she want then?" said the flounder.   「她想要甚么呀?」比目鱼问。   "Oh, flounder," he said, "my wife wants to become   emperor." 「唉,」渔夫回答说,「她要当皇帝。」   "Go home," said the flounder. "She is already emperor." 「回去吧,」比目鱼说,「她已当上了皇帝。」   Then the man went home, and when he arrived there, the entire palace was made of polished marble with alabaster statues and golden decoration. Soldiers were marching outside the gate, blowing trumpets and beating tympani and drums. Inside the house, barons and counts and dukes were walking around like servants. They opened the doors for him, which were made of pure gold. He went inside where his wife was sitting on a throne made of one piece of gold a good two miles high, and she was wearing a large golden crown that was three yards high, all set with diamonds and carbuncles. In the one hand she had a scepter, and in the other the imperial orb. Bodyguards were standing in two rows at her sides: each one smaller than the other, beginning with the largest giant and ending with the littlest dwarf, who was no larger than my little finger. Many princes and dukes were standing in front of her. 於是,渔夫往回走,到家时一看,整座宫殿都由研磨抛光的大理石砌成,石膏浮雕和纯金装饰四处可见。宫殿门前,士兵们正在列队行进,号角声,锣鼓声,震耳欲聋。在宫殿里,男爵、伯爵走来走去,个个一副奴才相。纯金铸造的房门为他一道道打开,他走进一看,妻子正坐在宝座上,宝座用一整块金子锻造而成,有数千英尺高。她头戴一顶宽大的金冠,足有三码高,上面镶嵌着无数珠宝;她一只手里握着皇仗,另一只手托着金球。在她的两侧,站着两列侍从,一个比一个矮,最高的看上去像个巨人,最矮的是个小侏儒,还没有他的手指大。她的面前侍立着不少王孙贵族。   The man went and stood among them and said, "Wife, are you emperor now?渔夫走了过去,站在他们的中间,说道:「老婆,你这回真的当皇帝啦?」   "Yes," she said, "I am emperor."   「是的,」她回答说,「我真的当皇帝了。」   He stood and looked at her, and after thus looking at her for a while, he said, "Wife, it is very nice that you are emperor." 渔夫往前移动了几步,想好好看看她。看了一会儿,他说:「哎,老婆,你当上了皇帝,真是太妙啦!」   "Husband," she said. "Why are you standing there? Now that I am emperor, and I want to become pope." 「喂!」她对渔夫说,「你还站在这里发甚么呆?我现在当上了皇帝,可是我还想当教皇。快去找比目鱼告诉他。」   "Oh, wife!" said the man. "What do you not want? There is only one pope in all Christendom. He cannot make you pope." 「哎呀,老婆,」渔夫说,「你到底想当甚么呀?你当不了教皇。在整个基督教世界教皇只有一个呀,比目鱼无法使你当教皇。」   "Husband," she said, "I want to become pope. Go there immediately. I must become pope this very day."  「   我的丈夫呀,」她说,「我要当教皇。快去吧!我今天就要当教皇。」   "No, wife," he said, "I cannot tell him that. It will come to no good. That is too much. The flounder cannot make you pope." 「不行呀,老婆,」渔夫回答说,「我可不想再去告诉比目鱼这个啦,那不行,那太过分啦。比目鱼无法让你当教皇的呀。」   "Husband, what nonsense!" said the woman. "If he can make me emperor, then he can make me pope as well. Go there immediately. I am emperor, and you are my husband. Are you going?" 「好啦,别再胡说八道啦!」她说,「他既然能让我当上皇帝,他当然也就能够让我当教皇了。马上去!我是皇帝,你只不过是我的丈夫而已,你马上就去!」   Then the frightened man went. He felt sick all over, and his knees and legs were shaking, and the wind was blowing over the land, and clouds flew by as the darkness of evening fell. Leaves blew from the trees, and the water roared and boiled as it crashed onto the shore. In the distance he could see ships, shooting distress signals as they tossed and turned on the waves. There was a little blue in the middle of the sky, but on all sides it had turned red, as in a terrible lightning storm. Full of despair he stood there and said: 渔夫胆战心惊,只得去了。他走在路上,感到浑身发软,两腿哆嗦。颤抖不止,海岸边的山上狂风呼啸,乌云滚滚,一片昏黑。树叶沙沙作响,海水像开锅了似地汹涌澎湃,不断拍打着他的鞋子。他远远地看见有些船只在狂涛中颠簸跳荡,燃放着求救的信号。天空一片火红,并且越来越红,只露出中间一点儿蓝色,好像一场暴风雨即将来临。渔夫站在那里,浑身颤抖,说道:   Mandje! Mandje! Timpe Te! Flounder, flounder, in the sea! My wife, my wife Ilsebill, Wants not, wants not, what I will 「比目鱼啊,你在大海里,恳请你好好听我说仔细,我捉你放你没提愿望,老婆对此却不饶又不依。」   "What does she want then?" said the flounder.   「她想要甚么呀?」比目鱼问。   "Oh," said the man, "she wants to become pope."   「唉!」渔夫回答说,「她要当教皇」   "Go home," said the flounder. "She is already pope."   「回去吧,她已当上了教皇。」比目鱼说。   Then he went home, and when he arrived there, there was a large church surrounded by nothing but palaces. He forced his way through the crowd. Inside everything was illuminated with thousands and thousands of lights, and his wife was clothed in pure gold and sitting on a much higher throne. She was wearing three large golden crowns. She was surrounded with church-like splendor, and at her sides there were two banks of candles. The largest was as thick and as tall as the largest tower, down to the smallest kitchen candle. And all the emperors and kings were kneeling before her kissing her slipper. 於是,渔夫往回走,到家时一看,一座大教堂矗立在那里,周围是几座宫殿。人们正潮水般拥挤着往里走。大教堂里燃着上千支蜡烛,照得四处通明雪亮,他老婆浑身上下穿戴着金子,坐在更高更大的宝座上,头上戴着三重大金冠。教会中的众多显贵簇拥在她的周围,她的两侧竖立着两排大蜡烛,最大一根大得就像一座高大的宝塔,而最小的一根则跟普通的蜡烛差不多。天下所有的皇帝和国王都跪在她的面前,争先恐后地吻她的鞋子。   "Wife," said the man, giving her a good look, "are you pope now?"   「老婆,」渔夫看着她说,「你现在真的是教皇了吧?」   "Yes," she said, "I am pope."   「是的,」她回答说,「我是教皇。」   Then he stood there looking at her, and it was as if he were looking into the bright sun. After he had looked at her for a while he said, "Wife, It is good that you are pope!" 说着他凑上前去,好好打量了一番,感觉她像耀眼的太阳一般,光辉灿烂。看了一会儿之后,他说:「老婆,你当了教皇,这可真是太了不起啦!」   She stood there as stiff as a tree, neither stirring nor moving.   可她呢,坐在那里泥雕木刻一样,一动不动。   Then he said, "Wife, be satisfied now that you are pope. There is nothing else that you can become." 接着他又说:「老婆,你已经当上了教皇,这回可该满足了,不可能还有比这更高的甚么啦。」   "I have to think about that," said the woman.   「这个嘛,我还得想一想,」妻子回答说。

凝胶层析法为什么能测出蛋白质的分子量?原理是什么?

原理简单说就是分子量不同通过凝胶柱的速度也不同凝胶是一种具有多孔,网状结构的分子筛.利用这种凝胶分子筛对大小,形状不同的分子进行层析分离,称凝胶层析 .凝胶层析的应用范围:凝胶层析法适用于分离和提纯蛋白质,酶,多肽,激素,多糖,核酸类等物质.分子大小彼此相差25%的样品,只要通过单一凝胶床就可以完全将它们分开.利用凝胶的分子筛特性,可对这些物质的溶液进行脱盐,浓缩,去热源和脱色.凝胶层析的优点凝胶层析具有设备简单,操作方便,分离迅速及不影响分子生物学活性等优点.目前已被广泛应用于各种生化产品的分离和纯化.-,凝胶层析的基本原理凝胶层析的原理l 分子大小不同混合物上柱; 2 洗脱开始,小分子扩散进人凝胶颗粒内,大分子被排阻于颗粒之外;3 大小分子分开: 4大分子行程较短,已洗脱出层析柱,小分子尚在进行中凝胶是一类多孔性高分子聚合物,每个颗粒犹如一个筛子.当样品溶液通过凝胶柱时,相对分子质量较大的物质由于直径大于凝胶网孔而只能沿着凝胶颗粒间的孔隙,随着溶剂流动,因此流程较短,向前移动速度快而首先流出层析柱;反之,相对分子质量较小的物质由于直径小于凝胶网孔,可自由地进出凝胶颗粒的网孔,在向下移动过程中,它们从凝胶内扩散到胶粒孔隙后再进入另一凝胶颗粒,如此不断地进入与逸出,使流量增长,移动速率慢而最后流出层析柱.而中等大小的分子,它们也能在凝胶颗粒内外分布,部分进入颗粒,从而在大分子物质与小分子物质之间被洗脱.这样,经过层析柱,使混合物中的各物质按其分子大小不同而被分离.

高效液相色谱与高效凝胶色谱是一回事吗

高效凝胶色谱是液相色谱的一种。高效液相色谱法(High Performance Liquid Chromatography HPLC)又称“高压液相色谱”,是以液体为流动相,采用高压输液系统,将具有不同极性的单一溶剂或不同比例的混合溶剂、缓冲液等流动相泵入装有固定相的色谱柱,在柱内各成分被分离后,进入检测器进行检测,从而实现对试样的分析。分类有反相色谱法,正相色谱法,分子排阻色潽法等。凝胶色谱法又称分子排阻色谱法。凝胶色谱主要用于高聚物的相对分子质量分级分析以及相对分子质量分布测试。高效凝胶色谱法即用现代高效液相色谱法所使用的高压流路系统,将分离凝胶装填到金属色谱柱中形成封闭液相系统进行分离的色谱法。实际上凝胶色谱在本质上就是液相色谱,只不过其分离原理是用凝胶对分子大小的排阻,而不是常规液相色谱法常用的利用物质极性。

凝胶色谱法测得的数均分子量为什么与核磁波谱法

凝胶色谱法测得的数均分子量为什么与核磁波谱法凝胶色谱法又称分子排阻色谱法。分离依据是目的物分子量的大小。主要用于高聚物的相对分子质量分级分析以及相对分子质量分布测试。形象来说更像是“分子筛”。大分子物质先流出,小分子物质后流出。凝胶电泳的原理比较简单。当一种分子被放置 在电场当中时 , 它们 就会 以一定 的速 度移向适当的电极 , 这种电泳分子在电场作用下的迁移速度 , 叫做电泳的迁移率。它同电场的强度和电泳分子本身所携带的净电荷数成正比。也就是说 ,电场强度越大、电泳分子所携带的净电荷数量越多 ,其迁移的速度也就越快 , 反之则较慢。由于在电泳中使用了一种无反应活性的稳定的支持介质 , 如琼脂糖凝胶和聚丙 烯酰胺 胶等 , 从而降低了对流运动 , 故 电泳 的迁移率又是同分子的摩擦系数成反比的。已知摩 擦系数 是分 子的大 小、极性及介质 粘度 的函数 , 因此根据分子大小的不同、 构成或形状的差异 , 以及所带的净电荷的多少 , 便可以通过电泳将蛋白质或核酸分子混合物中的各种成分彼此分离开来。形象来说更像是“马拉松”。不过影响因素不仅仅是分子量了。测DNA往往使用电泳技术,凝胶色谱一般用于提纯大分子物质。

凝胶层析的原理是什么?在操作中应注意哪些问题

高效液相色谱法(High Performance Liquid Chromatography HPLC)又称“高压液相色谱”、“高速液相色谱”、“高分离度液相色谱”、“近代柱色谱”等。高效液相色谱是色谱法的一个重要分支,以液体为流动相,采用高压输液系统,将具有不同极性的单一溶剂或不同比例的混合溶剂、缓冲液等流动相泵入装有固定相的色谱柱,在柱内各成分被分离后,进入检测器进行检测,从而实现对试样的分析。该方法已成为化学、医学、工业、农学、商检和法检等学科领域中重要的分离分析技术。高效液相色谱法按分离机制的不同分为液固吸附色谱法、液液分配色谱法(正相与反相)、离子交换色谱法、离子对色谱法及分子排阻色谱法。1.液固色谱法 使用固体吸附剂,被分离组分在色谱柱上分离原理是根据固定相对组分吸附力大小不同而分离。分离过程是一个吸附-解吸附的平衡过程。常用的吸附剂为硅胶或氧化铝,粒度5~10μm。适用于分离分子量200~1000的组分,大多数用于非离子型化合物,离子型化合物易产生拖尾。常用于分离同分异构体。 2.液液色谱法 使用将特定的液态物质涂于担体表面,或化学键合于担体表面而形成的固定相,分离原理是根据被分离的组分在流动相和固定相中溶解度不同而分离。分离过程是一个分配平衡过程。 涂布式固定相应具有良好的惰性;流动相必须预先用固定相饱和,以减少固定相从担体表面流失;温度的变化和不同批号流动相的区别常引起柱子的变化;另外在流动相中存在的固定相也使样品的分离和收集复杂化。由于涂布式固定相很难避免固定液流失,现在已很少采用。现在多采用的是化学键合固定相,如C18、C8、氨基柱、氰基柱和苯基柱。 液液色谱法按固定相和流动相的极性不同可分为正相色谱法(NPC)和反相色谱法(RPC)。 正相色谱法:采用极性固定相(如聚乙二醇、氨基与腈基键合相);流动相为相对非极性的疏水性溶剂(烷烃类如正已烷、环已烷),常加入乙醇、异丙醇、四氢呋喃、三氯甲烷等以调节组分的保留时间。常用于分离中等极性和极性较强的化合物(如酚类、胺类、羰基类及氨基酸类等)。 反相色谱法:一般用非极性固定相(如C18、C8);流动相为水或缓冲液,常加入甲醇、乙腈、异丙醇、丙酮、四氢呋喃等与水互溶的有机溶剂以调节保留时间。适用于分离非极性和极性较弱的化合物。RPC在现代液相色谱中应用最为广泛,据统计,它占整个HPLC应用的80%左右的时间。适用于分离非极性和极性较弱的化合物。RPC在现代液相色谱中应用最为广泛,据统计,它占整个HPLC应用的80%左右。

高中生物选修3关于凝胶色谱法的说法

根据我学到的生化知识。正确的应该是凝胶色谱是根据分子大小(也就是体积形状来分离的),说它是根据分子质量大小分离只是因为被分离的东西一般是蛋白质,而蛋白质的分子质量一般和其大小成正相关。 当不同分子大小的蛋白质流经凝胶层析柱时,比凝胶孔径大的分子不能进入凝胶珠内网状结构,被排阻在凝胶珠之外,随着溶剂在凝胶珠之间的孔隙向下移动,并最先流出柱外;比网孔小的分子能不同程度的自由进出凝胶珠的内外。这样由于不同大小的分子所经的路径不同而得到分离,大分子先被洗脱出来,小分子后被洗脱出来。 这个在高等教育出版社,王镜岩老师编的《生物化学》第301页 蛋白质的分离纯化原则上有详细解释。 至于你看到的练习和书本上为什么这样写,为了你考试能考高分,建议你拿我的答案和书上的区别去请教你们生物老师,得到他肯定的说法。
