其原由是参加这两种蛋白质合成的()A.tRNA 种类不一样B.mRNA碱基序列不一样C.核糖体成分不一样D.同一密码子所决定的氨基酸不一样1.B [ 分析 ]本题考察细胞的分化,考察学生的理解、剖析能力。
细胞合成蛋白质过程中,mRNA碱基序列直接决定着氨基酸摆列次序,而同一物种中的两类细胞内tRNA 种类和核糖体成分均同样,同一密码子决定的氨基酸也是同样的,所以本题选B。
2. [2012 ·课标全国卷 ]以下对于细胞癌变的表达,错误的选项是()A.癌细胞在条件适合时可无穷增殖B.癌变前后,细胞的形态和构造有显然差异C.病毒癌基因可整合到宿主基因组引发癌变D.原癌基因的主要功能是阻挡细胞发生异样增殖2.D [ 分析 ]本题考察细胞的癌变,考察学生的理解、剖析能力。
细胞癌变的原由就是致癌因子(包含物理致癌因子、化学致癌因子和病毒致癌因子)使原癌基因或抑癌基因发生突变,致使正常细胞的生长和分裂失控而变为癌细胞。
癌变后的细胞在形态构造上与正常细胞有显然的差异,所以A、B、C选项是正确的。
原癌基因的作用主假如负责调理细胞周期,控制细胞生长和分裂的进度;抑癌基因的作用主要是阻挡细胞发生不正常的增殖,所以D错误。
3.[2012 ·课标全国卷 ] 哺乳动物因长时间未饮水致使机体脱水时,会发生的生理现象是()A.血浆浸透压降低B.抗利尿激素分泌增添C.下丘脑浸透压感觉器遇到的刺激减弱D.肾小管和会合管对水的重汲取作用减弱3.B [ 分析 ]本题考察哺乳动物内环境稳态及其调理,考察学生的理解能力。
哺乳动物脱水时,细胞外液的浸透压会高升,血浆浸透压也会高升,对下丘脑浸透压感觉器的刺激加强,进而产生更多的抗利尿激素,促使肾小管和会合管对水分的重汲取,所以 B 正确。

2012年考研英语阅读Part A答案及解析

2012年考研英语阅读Part A答案及解析(Text 1第一篇文章出自 2011年3月24日的时代周刊(Times)上的一篇文章有关Herd Mentality的文章,维基百科上关于Herd Mentality的定义是:Herd mentality(从众心态) describes how people are influenced by their peers to adopt certain behaviors, follow trends, and/or purchase items. (从众心态描述的是人们怎样受到同辈人的影响去接受某些行为,追随潮流或购买东西),通俗的讲就是讲述人们的一种从众心态。
/time/magazine/article/0,9171,2061234,00. html21. According to the first paragraph, peer pressure often emerges as 根据第一段,来自同龄人的压力通常会变成为:[A] a supplement to the social cure 对社会治疗的一种补充[B] a stimulus to group dynamics 对团队活力的一种促进[C] an obstacle to school progress 对学校进步的一种阻碍[D] a cause of undesirable behaviors 不良行为的起因正确答案[D]理由:本题属于段落推理题,依据题干关键词peer pressure often emerge as=become回到原文查找到第一段第三句It usually leads to nogood---drinking, drugs and casual sex.(它指代前面的同辈人的压力通常不会导致任何好处,比如喝酒、毒品和乱性),由此可见同辈人的压力通常会给人带来坏处,也就是说带来消极的结果,属于贬义的方向,因此选项[D]中的cause 和原文的lead to, undesirable behaviors属于不好习惯的上义词,但都属于同义替换的命题技巧。

The research indicates that genetic factors influence some of the difference in the levels of salt we like to eat.Those conclusions are important because recent, well-publicized efforts to reduce the salt content in food have left many people struggling to accept fare that simply does not taste as good to them as it does to others, pointed out John Hayes, assistant professor of food science, who was lead investigator on the study.Diets high in salt can increase the risk of high blood pressure and stroke. That is why public health experts and food companies are working together on ways to help consumers lower salt intake through foods that are enjoyable to eat. This study increases understanding of salt preference and consumption.The research involved 87 carefully screened participants who sampled salty foods such as soup and chips, on multiple occasions, spread out over weeks. Test subjects were 45 men and 42 women, reportedly healthy, ranging in age from 20 to 40 years. The sample was composed of individuals who were not actively modifying their dietary intake and did not smoke cigarettes. They rated the intensity of taste on a commonly used scientific scale, ranging from barely detectable to strongest sensation of any kind."Most of us like the taste of salt. However, some individuals eat more salt, both because they like the taste of saltiness more, and also because it is needed to block other unpleasant tastes in food.” said Hayes. "Supertasters, people who experience tastes more intensely, consume more salt than do nontasters. Snack foods have saltiness as their primary flavor, and at least for these foods, more is better, so the supertasters seem to like them more.”However, supertasters also need higher levels of salt to block unpleasant bitter tastes in foods such as cheese, Hayes noted. "For example, cheese is a wonderful blend of dairy flavors from fermented milk, but also bitter tastes from ripening that are blocked by salt," he said. "A supertaster finds low-salt cheese unpleasant because the bitterness is too pronounced."Hayes cited research done more than 75 years ago by a chemist named Fox and a geneticist named Blakeslee, showing that individuals differ in their ability to taste certain chemicals. As a result, Hayes explained, we know that a wide range in taste acuity exists, and this variation is as normal as variations in eye and hair color."Some people, called supertasters, describe bitter compounds as being extremely bitter, while others, called nontasters, find these same bitter compounds to be tasteless or only weakly bitter." he said. "Response to bitter compounds is one of many ways to identify biological differences in food preference because supertasting is not limited to bitterness.”41. John Hayes points out in a recent study thatA. it is healthy to eat food without salt.B. many people reject low-salt food completely.C. food with less salt tastes better.D. many people accept low-salt tasteless food reluctantly.【答案】:D42. The fourth paragraph describes brieflyA. the purpose of the study.B. the analysis of the research results.C. the research methodology.D. the conclusion of the study.【答案】:C43. The article argues that supertastersA. like snack foods as saltiness is their primary flavor.B. like the taste of saltiness to block sweet tastes in food.C. consume less salt because they don't like intensive tastes.D. like to share salty cheese with nontasters.【答案】:A44. In paragraph 6, the word "pronounced" is closest in meaning toA. weary.B. strong.C. weak.D. strange.【答案】:B45. The last two paragraphs illustrate that taste acuity isA. developed over time after birth.B. related to one's eye and hair color.C. still unknown to scientists.D. genetically determined.【答案】:D第5部分:补全短文(第46~50题,每题2分,共10分)下面的短文有5处空白,短文后有6个句子,其中5个取自短文,请根据短文内容将其分别放回原有位置,以恢复文章面貌。

For example, mice, rabbits, and deer eat plants. owls eat mice and rabbits. Mountain lions eat rabhits and deer.These five species are parts of food chains that together form a food web.The first link in a food chain is always a green plant. Only organisms with chlorophy11, such as green plants can make food. for example, the first link aquatic food chains is algae. Most algae are microscopic green plants that produce food by photosynthesis. In photosynthesis, energy from sunlight converts carbon dioxide and water to sugar. Tiny fish in lakes, streams and oceans eat algae. In turn, these tiny fish are eaten by larger fish. The larger fish are eaten by still larger fish. The food supply for fish is made by algae. This food is then passed through the food chains as one animal eats another.Organisms may be divided into three groups based on how they obtain food. These groups are producers, decomposer and consumer. Organisms containing chlorophyll are producers. thus, green plants are producers. Animals that eat other animals and plants as consumers. Microbes, one-celled organisms that cause the decay of dead plants and animals are decomposers. Since decomposers cannot make their owm food, they are also consumers.1. The main purpose of the passage is to .A. determine which food chain is the most efficientB. describe the food network among plants and animalsC. explain the process of photosynthesis in green plantsD. appeal to conservationists to protect endangered plant specics2. According to the author, what is a "food web?A.A complicated system of several food chainsB.A society that distributes foodC. The relationship of one ereen plants to anotherD. The device that spiders use to catch food3. Which of the following would most likely be the first link in a food chain?A. TermitesB. FishC. LionsD. Grass4. The author divides organisms according to , A. how they use up energy B. how they obtain foodC. how much energy they require in order to moveD. whether they live on the land or in the sea5. Which of the following organism could not be a consumer as described in the passage?A.a microbeB.a rabbitC.a treeD.a fish(2) Lichens can be spectacular for anyone who cares to look, but few people take the trouble. Often modestly colored and seemingly two-dimensional as they cling to whatever surface they find, they grow in the background: as though designed to be ignored. Yet they hold a special fascination for botanists, partly because they present mysteries still to be solved and partly because they do so many things so well.No casual observer of a lichen would ever suspect that it was a composite of interacting life forms. The seemingly uncomplicated lichen is actually composed of afungus and a colony of algae(or blue-green algae, which some scientists now consider to be bacteria).A few species even include all three of these diverse forms of life.A complete lichen is strikingly different from its separated partners in both appearance and biochemistry; many produce unique compounds which cannot be made by the component organisms alone.Lichens grow in almost every natural habitat imaginable, from deserts to tropical rain forests-even on the back of certain beetles in New Guinca and inside rocks(along with algae) in the otherwise barren dry valleys of Antarctica.Many species can not tolerate extreme heat, cold or dryness. Very few, however, can survive heavy air pollution, and many live only where the air is very clean. The disappearance of lichens from an area gives warning of a threatened environment.1. Which of the following would be the best title for the passage?A. The versatility and complexity of the lowly lichenB. The hidden characteristics of algae coloniesC. The disappcarance of the lichen speciesD. The habitats of spectacular fungi2. The author states that lichens grow "as though designed to be ignored"because they are A. not totally understood by botanists B. troublesome to collect for the purposes of study C. uncomplicated in their intemal structure D. not easily noticed by observers3. According to the author, most people are unaware that lichen is a.A. lcafy plantB. class of simple bacteriaC. two-dimensional life formD. Combination of organisms4. The"unique"compounds mentioned in the second paragraph are produced A. through the cooperative efforts of the lichen's parts B. only under laboratory conditions C. through one of the three possible processes D. once in the lichen's life cycle5. The author implies that lichens might be used to.A. find water sourcesB. destroy unwanted plant lifeC. test for air purityD. provide food in remote areas(3) Insects' lives are very short and they have many enemies, but they must survive long enough to breed and perpetuate their kind.The less insect like they look, the better their chance of survival.To look "inedible"by resembling or imitating plants, is a deception widely practiced by insects. Mamals rarely use this type of camouflage, but many fishes and invertebrates do.The stick caterpillar is well named. It is hardly distinguishable from a bromn or green twig. This caterpillar is quite common and can be found almost anywhere in North America. It is also called "measuring worm"of "inchworm". It walks by arching its body, then stretching out and grasping the branch withits front feet, then looping its body again to bring the hind feet forward. When danger threatens, the stick caterpillar stretchesits body away from the branch at an angle and resains rigid and still, like a twig, until the danger has passed.Walkingsticks, or stick insects, do not have to assume a rigid, twiglike pose to find protection, they look like inedible twigs in anyposition. There are many kinds of walkingsticks, ranging in sizefrom the few inches of the North American variety to some tropicalspecies that may be over a foot long. Then at rest their front legs are stretched out. Some of the tropical species are adorned with spines or ridges, imitating the thorny bushes or trees in which they live.leaves also seem to be a favorite object for insects to imitate. Many butter flies can suddenly disappear from viem by folding their wings and sitting quietly among the foliage that they resemble.6. What is the main subject of the passage?E. Catepillars that live in treesF. The feeding habits of insectsG. How some insects camouflage themselvesH. Insects that are threatened with extinction7. In lines 1, the word "enemies"refers to E. other creatures competing for space F. extreme weather conditionsG. creatures that eat insects H. inedible insects8. According to the passage, how does the stick caterpillar make itself look like a twig?E. By holding its body stiff and motionlessF. By looping itself around a stickG. By changing the color of its skinH. By laying its body flat against a branch9. Which of the following is true of stick insects?E. They resemble their surroundings all the time.F. They make themselves look like other insects.G. They are camouflaged only when walking.H. They change color to make themselves invisible.10. Which of the following are not mentioned in the passage as ob jects that are imitated as a means of protection?A. ThornsB. FlowersC. leavesD. Sticks6. In which paragraph does the author describe the way in which stick caterpillars move?A. Paragraph oneB. Paragraph twoC. Paragraph threeD. Paragraph four(4) Wide-ranging research on tooth decay has recently produced some surprising findings, one indicates that cheddar may actually inhibit the tooth-decay process. It seems to have decay-slowing effect on human teeth if it is eaten immediately after sugar. Thy cheese should have such an effect is unknown. It is speculated that the food might interfere with the acidthat decays teeth or with bacteria that produce the acid. If so, it would be the first common food found to have this useful property. The other suprprising research finding was that heavily sweetened cereals proved ahout equally potent in causing decay whether they contained eight percent,sugar or almost eight times that much.1.According to the passage,how many of the test results were unexpected?A.OneB.TroC.ThreeD.Eight2.According to the passage,what effect does cheddar cheese seem to have?E.It interferes with the function of teeth.F.It makes sugar taste sueeter.G.It decreases the rate at which teeth decay.H.It helps in the digestion of food.3.It can be inferred from the passage that the research on the relationship between cheese and tooth A.has been discredited B.will be slowed considerablyC.has been found to be conclusiveD.will be continued4.Researchers discovered that sweetened cereals were A.important nutritionally B.all surprisingly heavy in sugar C.more expensive than cheese D.all equally harmful to teeth.四、短文翻译(第1题英文短句翻译成中文,每小题2分,共20分,第2题中文翻译成英文,20分,共40分)1.英文短句翻译成中文(1)A1l eukaryotic cells contain most of the various kinds of organelles,and each organelle performs a specialized function in the cell.(2)Photosynthesis occurs only in the chlorophyl1-containing cells of green plants,algae,and certain protists and bacteria.(3)A pictorial display of an organisms chromosomes in thecoiled,condensed state is knon as a karyotype.Karyotype reveal that in most cells all but sex chromosomes are present as two copies,referred to as homologous pairs.(4)An organism that inherits identical alleles for a trait from each parent is said to be homozygous for that traits:if different alleles for a trait are inherited,the organism is heterozygous for that trait.(5)The leading strand is synthesized continuously,while the lagging strand is synthesized in short stretches known as Okazaki fragments.(6)Taxonomy reveals a great deal about the evolutionary relationshipsamong organisms.A clade is a taxonomic unit whose mesbers are derived from a common ancestor.(7)A11 fungi carry out extracellular digestion:they secrete enzymes that digest organic matter,and then they absorb the resulting nutrients.(8)The organs and tissues of the embryo arise during organogenesis,as cells inside the embryo and on its surface become specialized.(9)Populations of a species that are spread out over a broad geographical range are often arrayed in a cline-a gradual change in one or more characteristics as each population evolves adaptations to its own local environment.(10)Just as competition,predation,and other elements interact todetermine the size of a population within a comsunity,population distribution is the result of many interrelated factors.2.短文翻译(中译英)蛋白质很难说明蛋白质在生命系统中有多么重要。

2.Sensitivity. Almost all living things respond to stimuli. Plants grow toward light, and animals retreat from fire. Not all stimuli produce responses, however. Imagine kicking a redwood tree or singing to a mushroom. Different kinds of organisms often react to the same stimuli in different ways. This criterion, although superior to the first one, is still inadequate to define life. 四、cloning (20分) You should write at least 100 words, and
