1、专科专科大学英语下大学英语下总共 7 题共 170 分一. （共 7 题,共 170 分）1. Part I Reading Comprehension (40%) Directions:There are four reading passages in this part. Each passage is followed by five questions. For each question there are four suggested answers marked A, B, C and D. Please choose one best answer Passage One Q
2、uestions 1-5 are based on the following passage: Usually a student must attend a certain number of courses in order to graduate, and each course which he attends, gives him a credit which he may count towards a degree. In many American universities the total work for a degree consists of thirty-six
3、courses each lasting for one semester. A typical course consists of three classes per week for fifteen weeks; while attending a university a student will probably attend four or five courses during each semester. Normally a student would expect to take four years attending two semesters each year. I
4、t is possible to spread the period of work for the degree over a longer period. It is also possible for a student to move between one university and another during his degree course, though this is not in fact done as a regular practice. For each course that he follows a student is given a grade, wh
5、ich is recorded, and the record is available for the student to show to prospective employers. All this imposes a constant pressure and strain of work, but in spite of this some students still find time for great activity in student affairs. Elections to positions in student organizations arouse muc
6、h enthusiasm. The effective work of maintaining discipline is usually performed by students who advise the academic authorities. Any student who is thought to have broken the rules, for example, by cheating, has to appear before a student court. With the enormous numbers of students, the operation o
7、f the system does involve a certain amount of activity. A student who has held one of these positions of authority is much respected and it will be benefit to him later in his career. (288) Passage Two Questions 6-10 are based on the following passage: Many people believe they are supposed to drink
8、eight glasses of water a day, or about two liters. Why? Because that is what they have been told all their life. But a new report offers some different advice. Experts say people should obey their bodies; they should drink as much water as they feel like drinking. The report says most healthy people
9、 meet their daily needs for liquid by letting thirst be their guide. The report is from theInstituteofMedicine, part of the National Academies. This organization provides scientific and technical advice to the government and the public. The report contains some general suggestions. The experts say w
10、omen should get about two-point-seven liters of water daily. Men should get about three-point-seven liters. But waitin each case that is more than eight glasses. There is an important difference. The report does not tell people how many glasses of water to drink. In fact, the experts say it may be i
11、mpossible to know how many glasses are needed to meet these guidelines. This is because the daily water requirement can include the water content in foods. People do not get water only by forcing themselves to drink a set number of glasses per day. People also drink fruit juices and sodas and milk.
12、They drink coffee and tea. These all contain water. As you might expect, theInstituteofMedicinesays people need to drink more water when they are physically active. The same is true of those who live in hot climates. Spending on heat and activity, people could need two times as much water as others
13、do.（270） Passage Three Questions 11-15 are based on the following passage: Trees are useful to man in three very important ways: they provide him wood and other products; they give him shade; and they help to prevent drought (干旱) and floods. Unfortunately, in many parts of the world, man has not rea
14、lized that the third of these services is the most important. In his eagerness to draw quick profit from the trees, he has cut them down in large numbers. Two thousand years ago, a rich and powerful country cut down its trees to build warships, with which to gain itself an empire. It gained the empi
15、re but, without its trees, its soil became bare and poor. When the empire fell to pieces, the country found itself faced by floods and starvation. Even where a government realizes the importance of a plentiful supply of trees, it is difficult sometimes to make the people realize this. They cut down
16、the trees but are too careless to plant and look after new trees. So, unless the government has a good system of control, or can educate the people, the forests slowly disappear. This does not only mean that there will be fewer trees. The results are even more serious: for where there are trees, their roots break the soil up, allowing the rain to sink in, and also bind the soil. This prevents the soil from being washed away. But where there are no trees, the rain falls on hard ground a
