Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the center.Questions 41 to 45 are based on the following passage:As supplier of most of the food we eat and of raw material for many industrial processes, agriculture is clearly an important area of the economy. But the productive performance of agriculture is even more important than this, because in nations where the productivity of farmers is low, most of the working population is needed to raise food and few people are available for production of industrial goods or for other activities required for economic growth. Indeed, one of the factors related most closely to the per capita income ( 人均收入) of a nation is the number of its population engaged in farming. In the poorest nations of the world, more than half of the population lives on farms. This compares sharply with less than 10 percent in Western Europe and less than 4 percent in the United States. In short, the course of economic development in general depends in a fundamental way on the productive performance of farmers. This performance, in turn, depends on how agriculture is organized and on the economic environment, or market structure, within which it works. In the following pages the performance of American agriculture is examined. It is reasonable to begin with a consideration of its market structure.41. This passage is most probably part of ______.A) a news item B) an advertisement C) a lecture D) an article42.

In the schools of ancient Greece and Rome, testing usually consisted of saying poetry aloud or giving speeches.In the European universities of the Middle Ages, students who were working for advanced degrees had to discuss questions in their field of study with people who had made a special study of the subject. This custom exists today as part of the process of testing students for the doctor's degree. Generally, however, modern examinations are written. The written examination, where all students are tested on the same questions, was probably not known until the nineteenth century. Perhaps it came into existence with the great increase in population and development of modern industry. A room full of students for a state examination, timed exactly by electric clocks and carefully watched over by managers, resembles a group of workers at an automobile factory. Certainly, during examinations teachers and students are expected to act like machines.One type of test is sometimes called an objective test. It is intended to deal with facts, not personal opinions. To set an objective test the teacher writes a series of questions, each of which has only one correct answer. Along with each question the teacher writes the correct answer and also three statements that look like answers to students who have not learned the material properly.46. In the Middle Ages students______.A) took objective tests B) were timed by electric clocksC) specialized in one subject D) seldom took written exams47. Nowadays a student working for the doctor's degree ___A) has to take a kind of oral examinationB) must ask a number of questionsC) has to write a poemD) must take an advanced examination ^48.

It may be concluded that examinations ______,A) should test only opinions B.! have changed since the Middle AgesC) should always be written D) are also given in factoriesQuestions 51 to 55 are based on the following passage;Crime has its own cycles, a magazine reported some years ago. According to the police records that have been studied for five years from over 2400 cities and towns, a surprising link is shown between changes in the season and crime patterns. The pattern of crime has varied very little over a long period of years. Murder reaches its high during July and August, as do other violent attacks. Murder, moreover, is more than seasonal: it is a weekend crime. It is also a nighttime crime: 62 percent of murders are committed between 6 p. m. and 6 a. m.Unlike the summer high in crimes of bodily harm, robbing has a different cycle. You are most likely to be robbed between 6 p. m. and 2 a. m. on a Saturday night in December, January, or February. The month with least crimes of all? May - except for one strange fact. More dog bites are reported in this month than in any other month of the year.Apparently our seasonal cycles of knowledge are completely different from our tendencies for crimes. Professor Huntington made extensive studies to discover the seasons when people read serious books, attend scientific meetings and get highest results on examinalions. In all cases, he found a spring high and autumn high separated by a summer low.Possibly, high temperature and high humidity (®jg) cause our strange and violent summer actions, but police officials are not sure. "There is. of course, no proof of a connection between humidity and murder," they say. "Why murder's high time should come in ihe summer time we really don't know. " 17251.
