1、考博英语-541 及答案解析(总分:100.00,做题时间:90 分钟)一、Part Reading Compr(总题数:5,分数:20.00)The opposite of adaptive divergence is an interesting and fairly common expression of evolution. Whereas related groups of organisms take on widely different characters in becoming adapted to unlike environments in the case of a
2、daptive divergence. We find that Unrelated groups of organisms exhibit adaptive convergence when they spot similar modes of life or become suited for special sorts of environments. For example, invertebrate marine animals living firmly attached to the sea bottom or to some foreign object tend to dev
3、elop a sub- cylindrical or conical form. This is illustrated by coral individuals, by many sponges, and even by the diminutive tubes of bryozoans. Adaptive convergence in taking this coral-like form is shown by some brachiopods and pelecypods that grew in fixed position. More readily appreciated is
4、the streamlined fitness of most fishes for moving swiftly through water; they have no neck, the contour of the body is smoothly curved so as to give minimum resistance, and the chief propelling organ is a powerful tail fin. The fact that some fossil reptiles (ichthyosaurs) and modem mammals (whales,
5、 dolphins) are wholly fishlike in form is an expression of adaptive convergence, for these air-breathing reptiles and mammals, which are highly efficient swimmers, are not closely related to fishes. Unrelated or distantly related organisms that develop similarity of form are sometimes designated as
6、homeomorphs (having same form).(分数:4.00)(1).Organisms that could be classified as homeomorphs are _.(分数:1.00)A.whale and dolphinB.halibut and whaleC.ichthyosaurs and dolphinsD.invertebrate marine animals and vertebrate marine animals(2).Adaptive convergence and adaptive divergence are _.(分数:1.00)A.m
7、anifestations of evolutionB.biological phenomenaC.ways in which plants and animals adjust to a common environmentD.demonstrated by brachiopods and pelecypods(3).Ichthyosaurs are _.(分数:1.00)A.mammals that live in the seaB.closely related to fishesC.fossil reptilesD.air-breathing animals(4).Invertebra
8、te marine animals are _.(分数:1.00)A.homeomorphsB.conical in formC.coralD.without bonesThe great question that this paper will, but feebly, attempt to answer is, What is the creative process?Though much theory has accumulated, little is really known about the power that lies at tile bottom of poetic c
9、reation. It is true that great poets and artists produce beauty by employing all the powers of personality and by fusing emotions, reason, and intuitions. But what is the magical synthesis that joins and arranges these complex parts into poetic unity?John L. Lowes, in his justly famous The Road to X
10、anadu, developed one of the earliest and still generally acceptable answers to this tantalizing question. Imaginative creation, he concludes, is a complex process in which the conscious and unconscious minds “jointly operate.“ “There isthe deep well with its chaos of fortuitously blending images; bu
11、t there is likewise the Vision which sees shining in and through the chaos the potential lines of Form, and with the Vision, the controlling Will, which gives to that potential beauty actuality.“The Deep Well is the unconscious mind that is peopled with the facts, ideas, feelings of conscious activi
12、ty. The imaginative vision, an unconscious activity, shines through the land of chaos, of lights and shadows, silently seeking pattern and form. Finally, the conscious mind again, through Will, captures and embodies the idea in the final work of art. In this way is unity born out of chaos.Though the
13、re can be no absolute certainty, there is general agreement that the periods in the development of a creative work parallel, to some extent, Lowes theory of Well, Vision, Form, and Will. There are at least three stages in the creative process: preparation, inspiration, work.In a sense, the period of
14、 preparation is all of the writers life. It is the Deep Well. It is especially a period of concentration which gives the unconscious mind an opportunity to communicate with the conscious mind. When remembrance of things past reaches the conscious level of the writers mind, he is ready to go on with
15、the process. Part of this preparation involves learning a medium-learning a language, learning how to write, learning literary forum. It is important to note here that form cannot be imposed upon the idea. Evidence, though sparse, shows that the idea gives birth to the form that can best convey it.
16、It is the Vision, according to Lowes, “which sees shining in and through the chaos the potential lines of Form /(分数:4.00)(1).When remembrance of things past reaches the conscious level, the poet has reached the stage called _.(分数:1.00)A.WellB.VisionC.FormD.Will(2).Which of the following statements i
17、s true?(分数:1.00)A.The form determines the subject matter.B.The idea determines the form.C.Vision makes beauty an actuality.D.A writers period of preparation is spent at school.(3).Fortuitously in the third paragraph means _.(分数:1.00)A.accidentallyB.luckilyC.thoroughlyD.unconsciously(4).The remembran
18、ce of things past is carried on in the _.(分数:1.00)A.Deep WellB.VisionC.chaotic lights and shadowsD.FormSince the Hawaiian Islands have never been connected to other landmasses, the great variety of plants in Hawaii must be a result of the long-distance dispersal of seeds, a process that requires bot
19、h a method of transport and an equivalence between the ecology of the source area and that of the recipient area.There is some dispute about the method of transport involved. Some biologists argue that ocean and air currents are responsible for the transport of plant seeds to Hawaii. Yet the results
20、 of flotation experiments and the low temperatures of air currents cast doubt on these hypotheses. More probable is bird transport, either externally, by accidental attachment of the seeds to feathers, or internally, by the swallowing of fruit and subsequent excretion of the seeds. While it is likel
21、y that fewer varieties of plant seeds have reached Hawaii externally than internally, more varieties are known to be adapted to external than to internal transport.(分数:4.00)(1).The author of the passage is primarily concerned with _.(分数:1.00)A.discussing different approaches biologists have taken to
22、 testing theories about the distribution of plants in HawaiiB.discussing different theories about the transport of plant seeds to HawaiiC.discussing the extent to which air currents are responsible for the dispersal of plant seeds to HawaiiD.resolving a dispute about the adaptability of plant seeds
23、to bird transport(2).The author mentions the results of flotation experiments on plant seeds most probably in order to _.(分数:1.00)A.support the claim that the distribution of plants in Hawaii is the result of the long distance dispersal of seedsB.lend credibility to the thesis that air currents prov
24、ide a method of transport for plant seeds to HawaiiC.suggest that the long-distance dispersal of seeds is a process that requires long periods of timeD.challenge the claim that ocean currents are responsible for the transport of plant seeds to Hawaii(3).It can be inferred from information in the pas
