No one knows why we sleep, but it’s certain that we need to. People who are prevented from sleeping begin to suffer obvious effects after a few days—they think less clearly, and they fall asleep during the working hours; some may have hallucinations(幻觉).
There are no rules about sleep. Generally speaking, grown-ups sleep about 7 and a half hours each night and probably more than 60 per cent get between seven and eight hours. But perhaps eight per cent are quite happy with 5 hours or less, and four per cent or so find that they want ten hours or more. If you feel all right, you’re probably getting enough sleep. The important thing is not to worry how much other people get—their needs may be different. Exercise doesn’t seem to increase the need for sleep—office workers, for example, sleep for about as long as people doing physically active work.
Children sleep more than grown-ups—perhaps 14 to 18 hours soon after birth, going down to grown-up levels by early teenage. Sleep patterns also tend(倾向) to be different in the elderly, who may sleep less at night than they did when younger, find sleep getting more broken, and often make it a rule to sleep during the daytime.
1.According to the passage, some people are unable to think clearly because ___________ .
A. they have hallucinations
B. they feel sleepy during the working hours
C. they don’t have enough sleep
D. they are certain to be kept from going to bed
2.Which of the following is TRUE?

B. Most of grown-ups sleep for seven or eight hours.
C. Quite a few people need only 5 hours or less for them to sleep.
D. No grown-ups sleep more than ten hours.
3.Whether you have got enough sleep is judged by__________.
A. how many hours you have slept
B. how many hours you need to sleep
C. whether you do exercise and physical work
D. whether you feel fresh and energetic
4.According to the passage, a boy of 14 years old sleeps__________.
A. as long hours as a grown-up
B. much longer hours than a grown-up
C. for 14 hours each night
D. for less than 8 hours per night

Some inventions are so useful, but seem so simple, that we wonder why no one thought of them long ago. Post-it Notes, the pieces of paper that you can stick almost anywhere and then remove without leaving any sign that they are there, are an example of such an invention.
Post-it Notes were invented about twenty years ago by Art Fry, a scientist at 3M Corporation. The idea for the product came from an upsetting experience he often had while singing in his church choir. Fry used pieces of paper as bookmarks to mark the places in his book of songs, but these bookmarks were always falling out. He knew he needed a bookmark that would stay where he put it, but that he could remove without damaging the pages.
Around that time, Fry heard about a new adhesive(粘合剂) that a colleague, Dr. Spence Silver had created. This adhesive was special because it was sticky, but not too sticky. It was strong enough to hold papers together, but weak enough not to tear the paper when it was removed. Fry saw that the new adhesive could help solve his bookmark problem. One morning, Fry put some of the adhesive on the edge of a piece of paper. Just as he hoped, it made a perfect bookmark.
A short time later, Fry realized that his new invention had even more uses than being a great bookmark. He came to this realization when he wrote a note on one of his new “bookmarks” and attached it to a report he was going to give to a colleague. Soon, co-workers were asking Fry for more sample of his invention so that they could use the new type of notes themselves.
Fry and some other people at 3M believed so much in the new product that they persuaded the company to give away thousands of the sticky pieces of paper for trial use. When some salespeople at 3M went to offices and showed workers just how helpful the new type of notes could be, they immediately received many orders. As more and more people discovered how useful Post-it Notes could be, the product took off.
1.The invention of Post-it Notes showed that Art Fry _____.
A. had a lot of knowledge. B. was very hard-working.
C. was good at creative thinking D. loved his job in the church
2.In what way did Dr. Spence help Art Fry?
A. They worked together and often discussed science.
B. His invention of a special adhesive made Art’s invention possible.
C. He persuaded 3M Corporation to give away lots of Post-it Notes for trial use.
D. He cooperated with Art by providing the new adhesive for Art.
3.Which of the following is a possible use of Post-it Notes?
A. A note on a friend’s door. B. An e-mail to a friend.
C. a postcard from abroad. D. An ad in a newspaper.
4.The biggest advantage of Post-it Notes is _____.
A. it can stay anywhere and leave no sign when removed.
B. it is very cheap to use.
C. it is good to write notes on
D. it is very thin and beautiful

It doesn't matter when or how much a person sleeps, but everyone needs some rest to stay alive. That's what all doctors thought, until they heard about Al Herpin.
Al Herpin, it was said, never slept. He was 90 years old when doctors came to his home in New Jersey. They expected to find out that he needed sleep of some kind. But they were surprised. Though they watched him every hour of the day, they never saw Herpin sleeping. He did not even own a bed. He never needed one.
The closest that Herpin came to resting was to sit in a rocking chair(摇椅) and read some news papers. The doctors were puzzled by this strange continuous sleeplessness. Herpin offered the only probable explanation of his condition. He remembered some talk about his mother having been injured several days before he was born.
