We begin this topic by discussing the region of the United States known as the Northeast. This region includes 11 states and a small area called the District of Columbia， which is the home of the national government.

The Northeast is a very important part of the United States， for although it covers only about six percent of the nations area， it contains around one-fourth of the countrys population. New York， the most popular city in the United States， and several other large cities lie in this region.

Why are these 11 states so important？ In the first place， the Northeast was one of the first sections of the country settled by Europeans. Busy cities developed there when most of America was still sparsely （稀疏地） settled. Many important events in the nations early history took place there， such as the Boston Tea Party in 1773， which took place immediately before the Revolutionary War broke out.

Today the Northeast is a great manufacturing （制造业） and trading region. Thousands of factories produce a wide variety of goods and provide other regions of the country with items they need. Many large manufacturing firms have their head offices here. Some of the countrys largest banks， investment agencies， and publishing houses are found in the Northeast. Several of its cities are noted for their fine museums. Some of the countrys best known colleges and universities are also found in this region.

Finally the Northeast is where the major part of the countrys inter-national trade takes place. In the heart of this region， in New York city， is the home of the United Nations.

Going to sleep may seem pretty boring compared with all the fun things you do while you are awake. But theres a lot going on in your mind and body while you are sleeping.

Sleep， in fact， is as important to your survival as eating and drinking. Sleep improves your mood， makes you a better athlete， and helps you remember and understand what you learned during the day.

During sleep your temperature drops. Your heart rate slows. Down goes the pressure of the blood moving through your veins （血管）. A chemical that controls growth （called a hormone） moves into your bloodstream. Scientists think that sleep brings back energy and improves your immune （免疫）system. We know what happens while were asleep because scientists study volunteers who sleep in laboratories. The sleepers are connected with machines that measure brain waves， eye movements and muscle activities.

Sleep is like a school day： its divided into different periods， or stages. When you are awake， your brain waves fire rapidly. As you begin to relax and drift into （不知不觉陷入） the first stage of sleep， your brain produces slower-moving waves and you lose awareness of your surroundings. As you slide to deeper sleep， your body repairs itself from the normal wear and tear of daily life. Then， as you begin to drift back up to a lighter sleep， your mind becomes more alert， and your dreams begin. You are in REM sleep.

REM is the name for the rapid eye movement that happens while you are dreaming. During REM sleep， your eyes move back and forth behind your eyelids， as though you were watching a movie. During other stages， you might move in bed， but during REM sleep youre still. Thats probably because if you could move， your body would act out your dreams. As you get close to morning， you spend more time in REM than in deep sleep， so you dream more. Researchers know that during REM sleep the part of the brain that deals with learning and thinking is very active.

Getting too little sleep can affect your personality. Experts recommend that children get at least nine hours sleep a night.

5. In which part of the course of sleep do you have more dreams？

A. Light sleep.

B. Deep sleep.

C. REM sleep.

③your dream begins

④you lose awareness of surroundings

A. ①③②④ B. ②④①③

C. ④①③② D. ④③①②

7. What does the underlined word “recommend” in the last paragraph mean？

A. Suggest. B. Order.

C. Wish. D. Ask.

8. Which of the following is TRUE about sleep according to the passage？

A. Hormone has nothing to do with your growth.

B. The whole brain is as active at night as in the day.

C. The closer to morning， the more dreams you have.

D. You move a little while you are in REM sleep， dreaming.

One dark and stormy night， an elderly man and his wife entered the hall of a small hotel in Philadelphia， hoping to get shelter for the night.

The clerk， a friendly man with a beautiful smile， explained that there were three conferences in town. “All of our rooms are taken，” the clerk said， “but I cant send a nice couple like you into the rain at one oclock in the morning. Would you perhaps be willing to sleep in my room？ Its not a suite， but it will be good enough to make you comfortable for the night.” The couple agreed.

As the elderly man paid the bill the next morning， he told the clerk， “You are the kind of person who should be the boss of the best hotel in the United States. Maybe someday Ill build one for you.” The clerk looked at them and smiled. The three of them had a good laugh.
