Concepts of reading have changed (26) over the centuries. During the 1950s and 1960s especially, increased attention has been dev

17、oted to (27) the reading process. (28) specialists agree that reading (29) a complex organization of higher mental (30) , they disagree (31) the exact nature of the process. Some experts, who regard language primarily as a code using symbols to represent sounds, (32) reading as simply the decoding o

18、f symbols into the sounds they stand (33) .These authorities (34) that meaning, being concerned with thinking, must be taught independently of the decoding process. Others maintain that reading is (35) related to thinking, and that a child who pronounces sounds without (36) their meaning is not trul

19、y reading. The reader, (37) some, is not just a person with a theoretical ability to read but one who (38) reads.Many adults, although they have the ability to read, have never read a book in its (39) . By some expert they would not be (40) as readers. Clearly, the philosophy, objectives, methods an

20、d materials of reading will depend on the definition one use. By the most (41) and satisfactory definition, reading is the ability to (42) the sound-symbols code of the language, to interpret meaning for various (43) , at various rates, and at various levels of difficulty, and to do (44) widely and

21、enthusiastically. (45) , reading is the interpretation of ideas through the use of symbols representing sounds and ideas.（分数：20.00）A.substantivelyB.substantiallyC.substitutivelyD.subjectivelyA.define and describeB.definition and descriptionC.defining and describingD.have defined and describedA.Altho

25、ral kinds of fish are able to do this. Even more strangely, this curious power has been acquired in different ways by fish belonging to very different families.Perhaps the best known are the electric rays, or torpedoes (电鳐), of which several kinds live in warm seas. They possess on each side of the

26、head, behind the eyes, a large organ consisting of a number of hexagonal shaped cells rather like a honeycomb. The cells are filled with a jelly-like substance, and contain a series of flat electric plates. One side, the negative side, of each plate, is supplied with very fine nerves, connected with

27、 a main nerve coming from a special part of the brain. Current passes from the upper, positive side of the organ downwards to the negative, lower side. Generally it is necessary to touch the fish in two places, completing the circuit, in order to receive a shock.The strength of this shock depends on

28、 the size of the fish, but newly born ones only about 5 centimetres across can be made to light the bulb of a pocket flashlight for a few moments, while a fully grown torpedo gives a shock capable of knocking a man down, and, if suitable wires are connected, will operate a small electric motor for s

29、everal minutes.Another famous example is the electric eel. This fish gives an even more powerful shock. The system is different from that of the torpedo in that the electric plates run longitudinally (纵向) and are supplied with nerves from the spinal (脊骨) cord. Consequently, the current passes along

30、the fish from head to tail. The electric organs of these fish are really altered muscles and like all muscles are apt (likely) to tire, so they are not able to produce electricity for very long.The power of producing electricity may serve these fish both for defence and attack.（分数：10.00）(1).It can b

31、e seen from the passage that _.（分数：2.00）A.the capacity to generate electricity is the distinctive characteristic of the fishB.the current travels in an upward direction from the positive side to negative side in torpedos electric cellsC.some fish can produce enough electricity to drive a number of e

32、lectricmotorsD.the torpedos electric cells have a shape with six sides(2).Usually you will not get a shock by touching the electric ray in one place only because _.（分数：2.00）A.the current in one place is not strong enough to give a shockB.the fishs electric cells are filled with jelly like substanceC

33、.to complete the circuit, you have to touch the fish in two placesD.a torpedos electric cells contain more than one electric plates(3).The main idea of the third paragraph is that _.（分数：2.00）A.a mature torpedo is capable of producing enough electricity to knock down a manB.the mass of the fish decid

34、es the intensity of electric power it generatesC.the strength of shock given by a young electric ray can only light the bulb of a pocket flashlightD.to make full use of the energy produced by electric fish, suitable wires should be available(4).The reason why the electric eel is able to give more po

35、werful shock is that _.（分数：2.00）A.the working system of the electric plates in the eel is the most effectiveB.the working system of the electric plates in the eel is far inferior to those in the torpedoC.compared with those in the torpedo, the working system of electric plates in the eel is more dir

36、ect and efficientD.compared with other electric fish, the eel possesses much more electric plates(5).The ideal title for this passage is _.（分数：2.00）A.The EelB.TorpedoC.Electric FishD.Electric Power八、Text 2(总题数：1，分数：10.00)Nowadays, a standard for measuring power has changed. These changes foretell a

37、new standard for measuring power. No longer will a nations political influence be based solely on the strength of its military forces. Of course, military effectiveness will remain a primary measure of power. But political influence is also closely tied to industrial competitiveness. Its often said

38、that without its military the Soviet Union would really be a third-world nation. The new standard of power and influence that is evolving now places more emphasis on the ability of a country to compete effectively in the economic markets of the world.America must recognize this new course of events.

39、 Our success in shaping world events over the past 40 years has been the direct result of our ability to adapt technology and to take advantage of the capabilities of our people for the purpose of maintaining peace. Our industrial prowess (杰出才能) over most of this period was unchallenged. It is ironi

40、c that it is just the prowess that has enabled other countries to prosper(繁荣) and in turn to threaten our industrial leadership.The competitiveness of Americas industrial base is an issue bigger than the Department of Defense and is going to require the efforts of the major institutional forces in o

41、ur society-not be a strong force in the process because we will. But we simply cannot be, nor should we be, liked upon by others as the savior (救星) of American industry.（分数：10.00）(1).Now a nations political influence depends on _.（分数：2.00）A.the strength of its military forcesB.its ability to compete

42、 in industryC.economic marketsD.both A and B(2).The Soviet Union was not being listed as a third-world nation just because of _.（分数：2.00）A.its industrial competitivenessB.its vast landC.its powerful military forcesD.its contributions to world peace(3).The author indicates that _ is threatening Ameri

43、can political power.（分数：2.00）A.other countriesB.less advanced technologyC.a new standard for measuring powerD.the declining U.S. industrial base(4).America succeeded in shaping world events over the past 40 years probably because of _.（分数：2.00）A.its ability to adapt technologyB.its ability to take a

44、dvantage of the capabilities of its peopleC.its ability to compete in the world marketsD.both A and B(5).The purpose of writing this article is _.（分数：2.00）A.to draw the readers attention to a new standard for measuring powerB.to demonstrate American political influence in the worldC.to emphasize tha

45、t effort must be made to strengthen the declining U. S. industrial baseD.to show American industrial prowers九、Text 3(总题数：1，分数：10.00)Greek mythology is largely made up of stories about gods and goddesses, but it must not be read as a kind of Greek Bible, an account of the Greek religion.According to

46、the most modern idea, a real myth has nothing to do with religion. It is an explanation of something in nature; how, for instance, any and everything in the universe came into existence: men, animals, this or that tree or flower, the sun, the moon, the stars, storms, eruptions, earthquakes, all that

47、 is and all that happens. Thunder and lightning ale caused when Zeus hurls his thunderbolt. A volcano erupts because a terrible creature is imprisoned in the mountain and every now and then struggles to get free. The Dipper (大熊星座), the constellation (星座) called also the Great Bear, does not set belo

48、w the horizon because a goddess once was angry at it and decreed (命令) that it should never sink into the sea. Myths ale early science, the result of mens first trying to explain what they saw around them.But there are many so-called myths which explain nothing at all. These tales are pure entertainm

49、ent, the sort of thing people would tell each other on a long winters evening. The story of Pygmalion (皮格马利翁) and Galatea is all example; it has no conceivable connection with any event in nature. Neither has the Quest of the Golden Fleece (录找金羊毛), nor Orpheus (奥菲士，竖琴圣手) and Eurydice, nor many another. This fact is now generally accepted; and we do not have to try to find in every mythological heroine the moon or the dawn and in every heros life a sun myth. The stories are early literature as well as early sc
