11、ollowing four texts. Answer the questions below each text by choosing A, B, C or D. (40 points) 21 However important we may regard school life to be, there is no denying the fact that children spend more time at home than in the classroom. Therefore, the great influence of parents cannot be ignored

12、or discounted by the teacher. They can become strong allies of the school personnel or they can consciously or unconsciously hinder and frustrate curricular objectives. Administrators have been aware of the need to keep parents informed of the newer methods used in schools. Many principals have cond

13、ucted workshops explaining such matters as the reading readiness program, manuscript writing and developmental mathematics. Moreover, the classroom teacher, with the permission of the supervisors, can also play an important role in enlightening parents. The informal tea and the many interviews carri

14、ed on during the year, as well as new ways of reporting pupils progress, can significantly aid in achieving a harmonious interplay between school and home. To illustrate, suppose that a father has been drilling Junior in arithmetic processes night after night. In a friendly interview, the teacher ca

15、n help the parent sublimate his natural paternal interest into productive channels. He might be persuaded to let Junior participate in discussing the family budget, buying the food, using a yardstick or measuring cup at home, setting the clock, calculating mileage on a trip and engaging in scores of

16、 other activities that have a mathematical basis. If the father follows the advice, it is reasonable to assume that he will soon realize his son is making satisfactory progress in mathematics, and at the same time, enjoying the work. Too often, however, teachers conferences with parents are devoted

17、to petty accounts of childrens misdemeanors, complaints about laziness and poor work habits, and suggestion for penalties and rewards at home. What is needed is a more creative approach in which the teacher, as a professional adviser, plants ideas in parents minds for the best utilization of the man

18、y hours that the child spends out of the classroom. In this way, the school and the home join forces in fostering the fullest development of youngsters capacities. 21 The central idea conveyed in the above text is that _. （ A） home training is more important than school training because a child spen

19、ds so many hours with his parents. （ B） teachers can and should help parents to understand and further the objectives of the school. （ C） there are many ways in which the mathematics program can be implemented at home. （ D） parents have a responsibility to help students in doing homework. 22 The aut

20、hor directly discusses the fact that _. （ A） parents drill their children too much in arithmetic. （ B） principals have explained the new art programs to parents. （ C） a parents misguided efforts can be properly directed. （ D） a father can have his son help him construct articles at home. 23 It can r

21、easonably be inferred that the author _. （ A） is satisfied with present relationships between home and school. （ B） feels that the traditional program in mathematics is slightly superior to the developmental program. （ C） believes that schools are woefully lacking in guidance personnel. （ D） feels t

22、hat parent-teacher interviews can be made much more constructive than they are at present. 24 We may infer that the writer of the article does not favor _. （ A） suggestions by the teacher to a parent in regard to improving the students scholastic average. （ B） written communications to the parent fr

23、om the teacher. （ C） having the parent observe lessons which the children are being taught. （ D） principal-parent conferences rather than teacher-parent conferences. 25 The author does not directly state, but implies that _. （ A） participation in interesting activities relating to a subject improves

24、 ones achievement in that area. （ B） too many children are lazy and have poor work habits. （ C） school principals do more than their share in interpreting the curriculum to the parents. （ D） teachers should occasionally make home visits to parents. 26 In 1575 over 400 years ago the French scholar Lo

25、uis Le Roy published a learned book in which he voiced despair over the changes caused by the social and technological innovations of his time, what we now call the Renaissance. We, also, feel that our times are out of joint; we even have reason to believe that our descendants will be worse off than

26、 we are. The earth will soon be overcrowded and its resources exhausted. Pollution will ruin the environment, upset the climate and endanger human health. The gap in living standards between the rich and the poor will widen and lead the angry, hungry people of the world to acts of desperation includ

27、ing the use of nuclear weapons as blackmail. Such are the inevitable consequences of population and technological growth if present trends continue. The future is never a projection of the past. Animals probably have no chance to escape from the tyranny of biological evolution, but human beings are

28、blessed with the freedom of social evolution. For us, trend is not destiny (fate). The escape from existing trends is now facilitated by the fact that societies anticipate future dangers and take preventive steps against expected changes. Despite the widespread belief that the world has become too c

29、omplex for comprehension by the human brain; modern societies have often responded effectively to critical situations. The decrease in birth rates, the partial prohibition of pesticides and the rethinking of technologies for the production and use of energy are but a few examples illustrating a sudd

30、en reversal of trends caused not by political upsets or scientific breakthroughs, but by public awareness of consequences. Even more striking are the situations in which social attitudes concerning future difficulties undergo rapid changes before the problems have come to pass witness the heated arg

31、uments about the problems of behavior control and of genetic engineering even though there is as yet no proof that effective methods can be developed to manipulate behavior and genes on a population scale. One of the characteristics of our times is thus the rapidity with which steps can be taken to

32、change the orientation of certain trends and even to reverse them. Such changes usually emerge from grass root movements rather than from official directives.

33、oot 群众。 26 According to the first two paragraphs, if present trends continue, which one of the following situations will not occur? （ A） An overpopulated earth will be unable to sustain its inhabitants. （ B） The rich will become richer and the poor will become poorer. （ C） New sources of energy will

34、 be substituted for oil and natural gas. （ D） The effects of pollution will pose a dreadful threat to mankind. 27 The best illustration of the meaning of “trend is not destiny“ in Para. 3 is that _. （ A） human beings are blessed with the freedom of social evolution. （ B） the world has become too com

35、plex for human beings to modify. （ C） preventive steps against catastrophes are difficult to be adopted. （ D） the earth will soon be overcrowded and its resources exhausted. 28 According to the text, evidences of the insight of the public into the dangers which surround us can be found in all of the

36、 following EXCEPT _. （ A） a decline in birth rates. （ B） opposition to the use of pesticides. （ C） pressing for better power production and energy use. （ D） a rapid increase in the funding of environment research. 29 The author is in favor of the opinion that _. （ A） the reversal of trend caused by

37、scientific advances is out of the question. （ B） nuclear weapons wont play a prominent role in dealings among peoples. （ C） the public is aware of the future dangers and ready to take immediate action. （ D） the trend of rapid development of science and technology seems irresistible. 30 The logical o

38、rganization of the text is that _. （ A） an assertion is made, followed by a few examples to illustrate it. （ B） future dangers are stated and relative measures are to be adopted. （ C） a historical trend is stated and evidence is then provided to prove it. （ D） examples of risks are given and reasons

39、 are then advanced to clarify them. 31 Within 80 years, some scientists estimate, the world must produce more than eight times the present world food supply. The productiveness of the sea raises our hopes for an adequate food supply in the future. Aided by men of science, we have set forth to find o

40、ut that 70 percent of the earth remains unexplored the ocean depths. Thus, we may better discover and utilize the seas natural products for the worlds hungry. It is fish protein concentrate that is sought from the seas. By utilizing the unharvested fish in United States waters alone, enough fish pro

41、tein concentrate can, be obtained to provide supplemental animal protein for more than one billion people for one year at the cost of less than half a cent per day per person. The malnutrition of children is terribly tragic. But the crime lies in societys unrestrained breeding, not in its negligence

42、 in producing fish powder. But wherever the population projects are carefully considered, the answer to the problem is something like this: There are few projects that could do more to raise the nutritional level of mankind than a full-scale scientific effort to develop the resources of the sea. Eac

43、h year some thirty million tons of food products are taken from the sea, which account for 12 percent of the worlds animal proteins. Nations with their swelling populations must push forward into the sea frontiers for food supplies. Private industry must step up its marine research and the federal g

44、overnment must make new attacks on the problems of marine research development. There is a tone of desperateness in all these designs on the sea. But what is most startling is the assumption that the seas are an untouched resource. The fact is that the seas have been, and are being, hurt directly an

45、d indirectly, by the same forces that have abused the land. In the broad pattern of ecological relationships the seas are not separable from what happens on the land. The poisons that pollute the soil and the air bring in massive doses into the “continental shelf“ waters. The dirt and pollution that

46、 spills from our urban sewers and industrial out falls despoil our bays and coastal waters. All the border seas are already heavily polluted by the same exploitation drives that have undermined the quality of life on land. Notes: sewers 下水道。 31 According to the text, which of the following statement

47、s is true? （ A） Though the situation is not urgent, we should press forward with our marine research. （ B） Nations throughout the world must be provided with fish, fresh or frozen, for needed protein. （ C） There are enough fish in the U.S. seas to allow for the annual protein needs of a quarter of t

48、he worlds 5 billion people. （ D） The oceans are the major source of the worlds protein supply. 32 The authors primary concern is that _. （ A） the oceans will help to provide enough food for the world in the future. （ B） thirty million tons of food products are taken from the sea every year. （ C） cit

49、y sewers are pouring forth polluted matter into bays and coastal waters. （ D） a steady increase in population will result in more hungry mouths to feed. 33 The author of the text is most probably of the opinion that _. （ A） the sea is an inexhaustible resource of food supply. （ B） the shortage of food supply mainly results from unrestricted population growth. （ C） the inadequate food supply is chiefly caused by the negligence in exploratio
