Passage 1
The home computer industry has been growing rapidly in the United States for the last ten years. Computers used to be large, expensive machines that were very difficult to use. But scientists and technicians have been making them smaller and cheaper while at the same time they have been made easier to use. As a result, their popularity has been increasing as more people have been buying computers for their homes and business.
Computers have been designed to store information and compute problems that are difficult for human beings to work out. Some have voices that speak with the operators. Stores use computers to keep records of their inventories（库存货物）and to send bills to their customers. Offices use computers to copy letters, record business and keep in touch with other offices. People have been using computers in their homes to keep track of the money they spend.
One important new use for computers is for entertainment. Many new games have been designed to be played on the computers. People of all ages have been playing these games. People also have been buying home computers to play computer games, watch movies and listen to concerts at home. They have become very popular indeed.

Passage 2
Do you find getting up in the morning so difficult that it becomes painful? This might be called laziness, but Dr. Kleitman has a new explanation. He has proved that everyone has a daily energy circle.
During the hours when you labor through your work you may say that you are “hot”. That’s true. The time of day when you feel most energetic is when your cycle of body temperature is at its peak. For some people the peak comes during the forenoon. For others it comes in the afternoon or evening. Not one has discovered why this is so, but it leads to such familiar monologues（自言自语）as “Get up, John! You’ll be late for work again!” The possible explanation to the trouble is that John is at his temperature-and-energy peak（最高点）in the evening. Much family quarrelling ends when husbands and wives realize what these energy cycles mean, and which cycle each member of the family has.
You can’t change your energy cycle, but you can learn to make your life fit it better. Habit can help, Dr. Kleitman believes. Maybe you’re sleepy in the evening but feel you must stay up late anyway. Counteract（对抗）your cycle to some extent by habitually staying up later than you want to. If your energy is low in the morning but you have an important job to do in the day, rise before your usual hour. This won’t change your cycle, but you will get up steam（鼓起干劲）and work better at your low point.
Get off to a slow start which saves your energy. Get up with a leisurely yawn and stretch. Sit on the edge of the bed a minute before putting your feet on the floor. Avoid the trouble some search for clean clothes by laying them out the night before. Whenever possible, do routine work（常规工作）in the afternoon and save tasks requiring more energy or concentration for your sharper hours.
11.If a person finds getting up early a problem, most probably _________.
A.he is a lazy person
B.he refuses to follow his own energy cycle
C.he is not sure when his energy is low
D.he is at his peak in the afternoon or evening

完形填空（共10小题，每小题3分，满分30分）
Picture this situation. It is late afternoon and you are   21   . You have an important dinner engagement that evening so you   22   to take an hour nap. Instead of setting your alarm you ask a friend who is visiting to wake you in an hour. He   23   .
Two hours later, your friend wakes you. You ask, “Why didn’t you wake me after one hour?” He   24   that he thought you asked him to wake you in two hours and that is what he said. You then have to run around and get ready quickly, muttering to yourself about how you   25   have set the alarm rather than asking your friend to wake you.

Your conclusion is correct. Your analysis of what happened looked at the system you used. Your friend’s   27   to wake you resulted from a miscommunication.   28   he didn’t hear you correctly or you misspoke.

34.要求在30分钟内，根据下面所给的题目和中文提纲用英语写出一篇不少于80词的短文。
My Roommate
1. 和我的室友相处很愉快/很不愉快。
2. 和我的室友相处愉快或不愉快的原因。

【参考例文】Living with my ex-roommate was unbearable. First, she thought everything she owned, from clothes to cosmetics, was the best. If someone complimented my pants, she’d point out that her designer jeans looked better and would last longer because they were made of better material. If she borrowed my shampoo, she’d let me know that it didn’t get her hair as clean and shiny as hers did. My hand cream wasn’t as smooth; my suntan lotion wasn’t as protective; not even my wire clothes hangers were as good as her padded ones! But despite her pickiness about products, she had numerous filthy habits. Her dirty dishes remained in the room for ages before she got the incentive to wash them. Piles of the “best” brand of tissues were regularly discarded from her upper bunk and strewn about the floor. Her desk and closets overflowed with heaps of dirty clothes, books, cosmetics, and whatever else she owned, and she rarely brushed her teeth (when she did brush, she left oozes of toothpaste on the sink). Finally, she constantly acted immaturely by throwing tantrums when things didn’t go her way. A poor grade on an exam or paper, for example, meant ashtrays, shoes, or any other small objects within her reach would hit the wall flying. Living with such a person taught me some valuable lessons about how not to win friends or keep roommates.
