1、大学英语三级 A 级-187 及答案解析(总分：100.00，做题时间：90 分钟)一、Reading Comprehensio(总题数：0，分数：0.00)二、Text 1(总题数：1，分数：20.00)It would be difficult to have a society like ours without public goods such as defense, transportation, and other services. A public good is one that a person can use without reducing the use of it

2、 for another person. One of the best examples of a public good is national defense. One person can benefit from our national defense without reducing another person“s benefits. In fact, it is difficult to keep any person in our society from enjoying the benefits of national defense. The market syste

3、m does not work well in producing public goods. This is because a person who refuses to pay for a public good cannot be kept from using it. Suppose that the neighbors in a high crime area decide to hire a police force. Each neighbor, except Mrs. Smith, agrees to pay $100 a year for it. Mrs. Smith re

4、fuses to pay because she knows that if all the others pay the $100, the police will guard the area anyway. So Mrs. Smith can enjoy the services of the police force without paying $100. The market system has no way to deal with this type of problem. For this reason, we cannot ask each person to make

5、a direct payment in the form of product price. Therefore, we collect money for public goods by using taxes.（分数：20.00）(1).According to the passage, public goods are _.（分数：4.00）A.the products that we make for national defenseB.what we can buy and sell in publicC.the services enjoyed by all peopleD.the

10、everyone on a mass basis or to find the gifted few and take them as far as they can go, our task would be fairly simple.

11、 produce specialists in many fields. Because we live in a democratic nation, whose citizens make the policies for the nation, large numbers of us must be educated to understand, to support, and when necessary, to judge the work of experts.

12、cientific services. In education, there should be a good balance among the branches of knowledge that contribute to effective thinking and wise judgment. Such balance is defeated by too much emphasis on any one field. This question of balance involves not only the relation of natural sciences, the s

13、ocial sciences, and the arts but also relative emphasis among the natural sciences themselves. Similarly, we must have a balance between current and classical knowledge. The attention of the public is continually drawn to new possibilities in scientific fields and the discovery of new knowledge; the

14、se should not be allowed to turn our attention away from the sound, established materials that form the basis of courses for beginners.（分数：20.00）(1).According to the first paragraph, the task of education is fairly complicated because _.（分数：4.00）A.the current public school system is too complicated

15、to be understoodB.the public school system has no such choice of what to teachC.it is difficult to decide whether elementary science should be taught in public schoolsD.the educators have to take care of both ordinary and gifted students(2).The word “defeated“ (Line 2, Para. 2) most probably means _

17、ized in public schools.D.In order to teach effectively, educators are requested to lay emphasis on one particular field.(4).It can be inferred from the passage that _.（分数：4.00）A.students should learn more up-to-date knowledgeB.lack of scientific knowledge will lead to poor relation between the produ
