考题 Animals other than humans have not developed communications comparable to human language. But is it possible that other animals have the capacity to learn a language if they are adequately taught? Obviously, this is a fascination notion. The idea of communicating directly with another species has long been a part of human folklore and children’s fantasies. But on a scientific level, the question of whether animals can learn a language is important primarily because it relates to the controversy()between the cognitive and the learning approaches to language. If language is dependent on and is actually an outgrowth of the intellectual structure of the human mind, there is the strong supposition that only humans are capable of using language. Therefore, Noam Chomsky and other psycholinguists have argued that only humans can learn a language, while most behaviorists feel that with sufficient patience it should be possible to teach an animal some sort of language. Although the two schools of thought clearly differ on this point, it is not really a crucial test of the two theories. If a chimpanzee can master a simple language all it would mean is that the chimp’s intellectual capacity and brain structure are more similar to ours than we thought. It would not necessarily imply that our intellectual structure is unimportant in our own mastery of language. Thus, teaching an animal language is an impressive demonstration of the power of learning techniques, but it is not evidence that language is developed entirely through learning.On the other hand, the question of whether other animals can learn a language is fascination in its own right, aside from its value as a test of the two theories of language development. Accordingly, whatever one’s position on the theoretical dispute, we must consider training an animal to use language a dramatic accomplishment.36.Which of the following statements is the view of psycholinguists?A. The cognitive view of language learning says that only human beings can learn language because it is an outgrowth of the structure of the human mind.B. Other animals simply could master a language.C. The animals intellectual capacity is much better than human beings.D. Language is developed by learning.37.The behaviorists’ view is that __________.A. language is actually an outgrowth of intellectual structure of the animal’s mindB. animals have not developed communications systemC. given enough patience, a man should be able to teach an animal some sort of languageD. only human beings can learn language38.That an animal can master a simple language means that __________.A. human’s intellectual structure is not importantB. animals’ intellectual capacity and brain structure are more similar to the humans’C. the learning techniques are much more importantD. language is developed completely by learning39.The main idea of paragraph two is ___________.A. teaching a chimp language is not crucial test of the two theoriesB. their brain structure is not similar to humanC. using various methods to let the chimp master a languageD. training a nonhuman to use language is an amazing accomplishment40.The best title for this passage would be _________.A. Animals’ languageB. Human’s languageC. Teaching Animals’ LanguageD. Can Other Animals Acquire Language?

考题阅读理解There is no doubt that man is a member of the animal kingdom.Anyone who has thought about this fact seriously must have wondered how it has come about that man has achieved a position so supreme(最高的) among the myriad(无数的) kinds of animal life.Two characteristics of man, in comparison with all other animals, that stand out above all others are the creation and use of tools and the development and use of language.Since no other animals have achieved these abilities, it must be assumed that man’s evolutionary development led to his capacity to create and use tools and to devise and use language.Once these abilities and practices evolved, they probably became driving forces in the further evolution of man.Those members of the species who become most proficient(精通的) in the fabrication of tools and in the command of language and thought would tend to survive and maintain their kind for good, at the expense of those of lesser ability.11.Which of the following statements best expresses the main idea of the passage?()A.Tools and language are either the effects or the causes of human evolution.B.No other animals have achieved human abilities.C.Among the animals, only man is able to use tools and language.D.Man owns his capacity to making use of tools and language.12.“Animal kingdom” in the passage refers to ().A.the place where all animals liveB.the animal societyC.all kinds of animals, including manD.the forest with animals13.One important condition for man’s evolution is() .A.the animal kingdomB.a supreme positionC.the myriad kindsD.his natural capacity14.The phrase “come about” in the passage is likely to mean ________.A.happenedB.appearedC.arrivedD.succeeded15.The last sentence suggests that() .A.those of lesser ability would be very expensiveB.in order to survive, man has to sacrifice some other animalsC.those who become proficient in making tools can speak wellD.language and thought could be acquired by man

考题 Most animals have little connection with animals of different kind, unless they hunt them for food. Sometimes, however, two kinds of animals come together in a partnership ( 伙伴关系 ) which does good to both of them. You may have noticed some birds sitting on the backs of sheep. This is not because they want a ride, but because they find easy food in the parasites (寄生虫 ) on sheep. The sheep allow the birds to do so because they remove the cause of discomfort. So although they can manage without each other, they do better together.Sometimes an animal has a plant partner. The relationship develops until the two partners cannot manage without each other. This is so in the corals ( 珊瑚 ) of the sea. In their skins they have tiny plants act as "dustman", taking some of the waste products form. the corals and giving in return oxygen which the animal needs to breathe. If the plants are killed, or are ever prevented from lighting so that they cannot live normally, the corals will die.1、Some birds like to sit on a sheep because ( ).A、they can eat its parasitesB、 they depend on the sheep for existenceC、 they enjoy traveling with the sheepD、 they find the position most comfortable2、The underlined word "they" in the last sentence of the first paragraph refers to ( ).A、birds and parasitesB、birds and sheepC、parasites and sheepD、sheep, birds and parasites3、What does the second paragraph mainly discuss? ( )A、Some animals and plants depend on each other for existence.B、 Some animals and plants develop their relationship easily.C、 Some plants depend on each other for fooD、 Some animals live better together.4、What does this article talk about? ( )A、Two kinds of animals for a partnership.B、Most animals only have connection with animals.C、The connection between the living things.D、Corals have some connection with plants.

考题问答题Practice 2　　Transgenic plants and animals result from genetic engineering experiments in which genetic material is moved from one organism to another, so that the latter will exhibit a characteristic. Business corporations, scientists, and farmers hope that transgenic techniques will allow more cost-effective and precise plants and animals with desirable characteristics that are not available using up to date breeding technology.　　Transgenic techniques allow genetic material to be transferred between completely unrelated organisms.　　In order for a transgenic technique to work, the genetic engineer must first construct a transgene, which is the gene to be introduced plus a control sequence. When making a transgene, scientists usually substitute the original promoter sequence with one that will be active in the correct tissues of the recipient plant or animal.　　The creation of transgenic animals is one of the most dramatic advances derived from recombinant DNA technology. A transgenic animal results from insertion of a foreign gene into an embryo. The foreign gene becomes a permanent part of the host animals’ genetic material. As the embryo develops, the foreign gene may be present in many cells of the body, including the germ cells of the testis or the ovary. If the transgenic animal is fertile, the inserted foreign gene (transgene) will be inherited by future progeny. Thus, a transgenic animal, once created, can persist into future generations. Transgenic animals are different from animals in which foreign cells or foreign organs have been engrafted. The progeny of engrafted animals do not inherit the experimental change. The progeny of transgenic animals do.　　The techniques for creating a transgenic animal include the following: 1) picking a foreign gene, 2) placing the foreign gene in a suitable form called a “construct” which guides the insertion of the foreign gene into the animal genome and encourages its expression, and 3) injecting the construct into a single fertilized egg or at the very early embryo stage of the host animal. Much genetic engineering goes into the choice of a foreign gene and building a construct. The construct must have promoters to turn on foreign gene expression at its new site within the host animal genome. By choosing a particular promoter and splicing it in front of the foreign gene, we can encourage expression of our transgene within a specific tissue.　　One of the most important applications of transgenic animals is the development of new animal models of human disease. Transgenic animals can serve as models for many malignant tumors. Mice have been the most frequent hosts for transgenic modification, other domestic animals have also been used. One idea has been to create transgenic cows which secrete important pharmaceutical substances in their milk. Other attempts are being made to express human interferon in the milk of sheep.　　A transgenic crop plant contains a gene or genes which have been artificially inserted instead of the plant acquiring them through pollination. The inserted gene sequence (known as the transgene) may come from another unrelated plant, or from a completely different species: transgenic BT corn, for example, which produces its own insecticide, containing a gene from a bacterium. Plants containing transgenes are often called genetically modified or GM crops although in reality all crops have been genetically modified from their original wild state by domestication, selection and controlled breeding over long periods of time.
