Part II. Reading Comprehension (30%)
Passage One:
When John and V ictoria Falls arrived in New Y ork City for one-year stay, they did not bring very many things with them. They had planned either to live in a furnished apartment or to buy used furniture. But they soon learned about a new system that more and more people are using. The renting of home furnishings (bed, tables, dishes, and so on) has become one of America’s fastest growing businesses.
What kinds of people rent their home furnishings instead of buying them? People who are international business or government officials, foreign students, airline workers, young married couples --- people whose job or business may force them to move frequently from one city to another. They save a lot of trouble and the cost of moving their furniture each time. They simply rent new furniture when they reach their new homes. Y oung people with little money do not want to buy cheap furniture that they may soon dislike. They prefer to wait until they have enough money to buy furniture they really like. Meanwhile, they find they can rent better quality furniture than they could afford to buy.
One family, who now have a large, beautiful home of their own, liked their rented furniture so much that they decided to keep renting it instead of buying new things. But usually people don’t like to tell others about it. The idea of renting home furnishings is still quite new, and they are not sure what their neighbors might think.

businesses?
A. Selling home furnishings.
B. Renting furnished apartments.

A.Because the furniture they get in this way is new.
B.Because it saves them a lot of money.
C.Because it saves them much trouble and money.
D.Because they can always get better quality furniture in this way.
3.What can you infer from the passage?

B.Renting furniture is not popular in the couple’s home tow n.
C.Only those who don’t have enough money rent furniture.
D.People usually grow to like the furniture they have rented.
4.Which of the following can best serve as the title of the passage?

C. The new furniture is of good quality.
D. They don’t have much money and don’t want to buy the cheap furniture.
Passage Two:
For the most part, rapid economic development has been a boon. But there is a down side to development –health problems such as overweight are all becoming more prevalent, as more people take taxis to work instead of riding their bicycles, and other labor-saving devices become more popular.
An increasing fast pace of life makes it difficult for people to spend time working out or playing sports. “I know exercise is good for your health,” a young lady said. “But afte r a busy work week, the only thing I want to do is watch some TV and go to sleep.” That attitude may explain the results of a recent nationwide study, which suggested 15 percent of urban adults I China are overweight, a large number of people over the age of 40 suffer from high blood pressure and cardiac ailments.
Local researchers found that 31.2 percent of elderly respondents were getting enough exercise, but less than 9 percent of youngsters and the middle-aged got an adequate amount of physical activity.
Elderly people understand the importance of protecting their health. The young people, however, are busy working and use this as an excuse to avoid exercise. In fact, physical exercise doesn’t require much time, money or a special gymnasium. People can make use of any time and any place at their convenience to take part in sports. Walking quickly, cycling, climbing the stairs and dancing are all helpful methods to enhance one’s health.
The benefits of adding a little more activity to your lift are priceless. “There is no need to be an athlete, however,” a local doctor said. People should walk for 30 minutes a day and take part in other physical activity three to five times a week. He warns, however, that people in poor physical shape should start slowly, and build up over time.
China has taken the need for more exercise to heart, with the government running several activities last Sunday, which was the designated World Health Day. Pamphlets and posters based on the theme“Move for Health” wer e distributed nationwide, encouraging people to develop a positive and healthy lifestyle.
6.Rapid economic development has resulted in all the following except ____.
A.an increasing number of taxi passengers
B.the wide use of labor-saving devices
C.an increasingly fast pace of life
D.people’s awareness of the importance of exercise
7.Some people are getting overweight because ____.
A.they are too busy to have any time for exercise
B.they are ignorant of the benefits of exercise
C.they are too weak to participate in physical activity
D.they are short of money to pay for different exercises
8.According to the passage, who need regular daily exercise most?
A.People taking taxis to work.
B.Urban adults with full-time jobs.
C.Elderly people suffering from high blood pressure.
D.Y oungsters dreaming of becoming professional athletes.
9.What is the main idea of the last paragraph but one?
A.Many people are still unable to afford the cost of physical exercises.
B.Nobody should take part in physical activity in order to be an athlete.
C.Moderate physical exercise is usually enough for ordinary people.
D.Old or sick people should only take part in physical exercises of the
slowest type.
10.By referring to rapid economic development as “a boon” at the beginning of
the passage, the author means that ____.
A.it has benefited the general public greatly
B.it has done harm to people’s health nationwide
C.it is going faster than anyone could have imagined
D.it has helped to establish a positive and health lifestyle of the public
Passage Three:
Every human being, no matter what he is doing, gives off body heat. The usual problem is how to dispose of it. But the designers of the Johnstown campus of the University of Pittsburgh set themselves the opposite problem –how to collect body heat. They have designed a collection system which utilizes not only body heat, but the heat given off by such objects as light bulbs and refrigerators as well. The system works so well that no conventional fuel is needed to make the campus’s six buildings comfortable.
Some parts of most modern buildings –theaters and offices as well as classrooms –are more than amply heated by people and lights and sometimes must be air-conditioned even in winter. The technique of saving heat and redistributing it is called “heat recovery”. A few modern build ings recover heat, but the University’s system is the first to recover heat from some buildings and
reuse it in others.
Along the way, Pitt has learned a great deal about some of its heat producers. The harder a student studies, the more heat his body gives off. Male students emit more heat than female students, and the larger a student, the more heat he produces. It is tempting to conclude that the hottest prospect for the Johnstown campus would be a hard-working, overweight male genius.
11.Until recently, body heat has caused problems because it_____.
A. was difficult to collect
B. came in variety of forms
C. was difficult to get rid of it
D. tended to be absorbed by physical objects
12.Which of the following is true of the heating system of the Johnstown
campus?
A. The heat is supplied by human bodies
B. The heat is supplied by both human bodies and other
heat-emitting objects
C. The heat is supplied by both human bodies and conventional fuel
D. The heat is supplied by human bodies, other heat-emitting objects, and conventional fuel
13.At the Johnstown campus, how many of the buildings are heated entirely by
the heat collection system?
A. None
B. Two
C. Four
D. Six
14.According to the passage, which of the following would produce the
LEAST amount of heat?
A. A fat female who studies hard
B. A thin female who does not study
C. A fat male who does not study
D. A thin male who studies hard
15.In the last paragraph, the “hottest prospect” means the____.
A. most intelligent student
B. most desirable student
C. most diligent student
D. most learned student
Passage Four：
The resources of the library can be helpful even when we are doing something very informal, such as trying to devise a better way to measure attitudes toward music or looking for a better way to teach mathematics. The library can be equally helpful when we are doing something very formal, such as writing a dissertation (学位论文) or preparing an article for publication in a professional journal. In either case, our goal should be to use the library as a useful tool to help us understand and solve our problem.
The following sections of this chapter will describe specific resources available in many libraries. In some cases you may already be aware of a resource and may use it frequently and successfully. In other cases you may be completely unfamiliar with a resource. Y our goal should be to become aware of what is available and to know how to use each of these resources to help you solve the problem they are designed to solve.
When educators have a piece of information that they want to share with their colleagues, they often make this information available in professional journals or at professional meetings. It would often be useful to have access to such information, and this chapter will describe the special services that enable us to locate such information.
16.The library resources can be helpful when we ______.
A. want to find a better way to measure attitudes toward music
B. are preparing a paper for a professional journal
C. are writing a dissertation
D. All of the above
17.Readers’ familiarity with different resources ______.
A. is more or less the same
B. varies slightly
C. differs greatly
D. should not be different
18.The author believes that ______.
A. library resources should be used frequently and completely
B. library resources cannot be made good use of if they are not available to
us
C. one is supposed to be aware of the library resources that are usually not
available
D. one is supposed to have good knowledge and make good use of library
resources
19.When educators wish to share some information with their colleagues, they
often ______.

期末考试注意事项 尊敬的各位家长，大家下午好！史诗级大片《期末考试》即将上演，此时是学生最兴奋，却也是最紧张的时候。如何做好考前准备，温馨提示如下： 一、考前准备 (1)早睡 为了保证精力充沛，一定要早睡。这样可以保证第二天早起。时间充足，准备充分，心不忐忑。 (2)早饭 以清淡为主，辅以鸡蛋面包火腿，能量要够就可以。 (3)如厕 建议饭早吃，在上学前上好厕所。 (4)文具检查 铅笔最少四支，橡皮两块，尺子一把(语数连线)。 (5)准备一本道德与法治之类的书，垫在卷子下面，防止写破或者擦破卷子，影响卷面美观。 (6)心态 告诉孩子像平时一样只不过是做一份卷子而已，家长切记絮絮叨叨，千叮咛万嘱咐，这样会增加孩子的心理负担。 二、考中 (1)在卷子的上方写清楚自己的班级、姓名。
(2)发下卷子后，在老师的提醒下，检查自己的卷子有没有少印漏印现象，如果有要及时举手和老师报告换卷。 (3)一定要在老师的带领下做题。老师读一道，孩子做一道，即使后边的题型自己会，也不要贸然去做。一定要和老师读题速度同步。 (4)每当自己完成一道题后要养成随时检查的好习惯。 (5)认真规范书写，不急不躁。因为老师会等待书写慢的同学。 (6)老师读题时，如果没有听懂，大胆举手要求老师再读，直到自己明白题的意思和要求。 (7)学会倾听，老师读到难题时语气声调会有变化，也会有侧重点地去读，考场上尤其要学会静心倾听。 (8)无论数学还是语文连线题一定要用直线型，不要用折线和曲线。 (9)无论语文数学一定要认真看图。尤其数学要认真观察，才不会出现数错数这样的低级错误。还有从左数，还是从右数，一定要听清楚前提条件。 (10)语文组词类型的题，最好组自己确定会写的字，如果不确定最好标注拼音。 (11)一年级孩子们因为不会写的字多，所以千万要记得音节之间要空开一个字的距离，卷子上没有拼音的四线三格，字数不宜长，只要能说清楚图上的意思，一两句即可。 (12)试卷写完后，一定要紧跟老师的步伐，一道一道检查，不可懒惰。多数一年级的小家伙们，一次成型，不喜欢检查。所以，如果时间允许，一般监考老师会提醒孩子们检查一到两次。
