    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.

56. The point of this story is that _______.

 A. We needn't feel surprised to find someone who doesn't sleep

 B. one person was found who actually didn't need any sleep

C. everyone needs some rest to stay alive

 D. not sleeping may help one to live longer

57. After watching him closely, the doctors believed that Al Herpin _______.

 A. needed some kind of sleep    B. slept while one was watching

 C. needed no sleep at all     D. nearly slept in a rocking chair

58. One suggested explanation of Herpin's sleeplessness was _______.

 A. his old age     

B. his not having a bed

 C. his magnificent physical condition

 D. his mother's injury while carrying him

59.The writer of the story obviously thinks that Al Herpin's sleeplessness ___.

 A. could be cured     B. could be explained

 C. was healthful      D. was uncommon  

Personal computers and the Internet give people new choices about how to spend their time.

Some may use this freedom to share less time with certain friends or family members, but new technology will also let them stay in closer touch with those they care most about. I know this from personal experience.

E-mail makes it easier to work at home, which is where I now spend most weekends and evenings. My working hours aren’t necessarily much shorter than they once were but I spend fewer of them at the office. This lets me share more time with my younger daughter than I might have if she’d been born before electronic mail became such a practical tool.

The Internet also makes it easy to share thoughts with a group of friends. Say you do something fun—see a great movie perhaps—and there are four or five friends who might want to hear about it. If you call each one, you may tire of telling the story.

With E-mail, you just write one note about your experience, at your convenience, and address it to all the friends who you think might be interested. They can read your message when they have time, and read only as much as they want to. They can reply at their convenience, and you can read what they have to say at your convenience.

E-mail is also an inexpensive way to stay in close touch with people who live far away. More than a few parents use E-mail to keep in touch, even daily touch, with their children off at college.

We just have to keep in mind that computers and the Internet offer another way of staying in touch. They don’t take the place of any of the old ways.

The purpose of this passage is to ________.

explain how to use the Internet       

describe the writer’s joy of keeping up with the latest technology

tell the merits(价值) and usefulness of the Internet

introduce the reader to basic knowledge about personal computers and the Internet

The use of E-mail has made it possible for the writer to ________.

  A. spend less time working         B. have more free time with his child

  C. work at home on weekends      D. work at a speed comfortable to him

According to the writer, E-mail has an obvious advantage over the telephone because E-mail helps one ________.

A. reach a group of people at one time conveniently

B. keep one’s communication as personal as possible

C. pass on much more information than the latter

D. get in touch with one’s friends faster than telephone.

The best title for this passage is _________.

Computer: New Technological Advances

Internet: New Tool to Maintain Good Friendship

Computer Have Made Life Easier

Internet Have helped us to communicate

The huge Florida wetland known as the Everglades is a slow-moving river 80 kilometres wide but only a few centimeters deep. People call the Everglades a “river of grass” because sawgrass covers most of it. Sawgrass is not really grass. It is a plant that has leaves edged with tiny sharp teeth that can easily cut through clothes—and skin!

Travel in the Everglades is difficult. You cannot walk through shallow water because the sawgrass will cut you. The water is too shallow for regular boats. So, we use an airboat. An airboat is a flat, open boat. Like an airplane, it has a big propeller to move it. The propeller is fixed on the rear of the boat. It makes a tremendous noise, but it does the job. The boat skims along the water’s surface. Although we can still get lost in an airboat, at least we are above the alligators(短吻鳄).

   While hundreds of different kinds of animals live in the Everglades, the most famous is surely the alligator. Once endangered, alligators are now protected within Everglades National Park. Visitors are likely to see them both on land and in water.

   For a long time, dangers have threatened the Everglades. Around 1900, some people felt this precious wetland should be drained (排干). They said it was just a big swamp and not good for anything. In the 1920s, there was a land boom in Florida. People wanted to build homes everywhere, including in the Everglades. They built canals, levees (防洪堤) , and other water systems that stopped the rivers flowing into the Everglades. Factories were built near rivers that flowed into the wetland. These factories dumped poisonous waste that damaged the Everglades ecosystem.

? People are now working to preserve the Everglades National Park for the future. Right now, one big problem is the paperbark tree. This tree is an invader from Australia.

    Paperbark trees soak up a lot of water. In the early 1900s, people brought them to Florida because they thought they would help drain the Everglades. However, the invaders adapted too well. Paperbark trees have taken over hundreds of thousands of acres of the Everglades and killed other trees. Scientists are cutting down these invaders or spraying them with herbicides (除草剂) to kill them. ?

Which helps to explain why it is difficult to travel in Everglades?

     A. Airboats may make a very big noise.

     B. You may get lost when passing through.

     C. Paperbark trees soak up too much water there.

     D. Many different kinds of animals are to be protected.

Why do people use airboats instead of normal boats?

     A. They have big propellers to move them faster than alligators.

     B. The propeller makes loud noise so as to scare alligators.

     C. Their flat bottom can skim along the water surface.

     D. They can watch alligators without hurting them. ?

The following measures were taken to drain the Everglades except that people______. ?

     A. built canals and levees to stop the rivers flowing into Everglades?

     B. built factories near rivers that flowed into the wetland?

     C. brought Paperbark to soak up water in Everglades?

     D. are cutting down these Paperbark trees?

The underlined word "invader" probably means something______. ?

     A. that moves in from another place     B. that enters and takes control?

     C. that has been brought in?                     D. that is in danger?
