阅读理解。    Although man has known asbestos for many hundreds of years, it was not until 160 years ago that it was
mined for the first time on the North American continent.H.W.Johns, owner of a New York City Supply Shop
for roofers, was responsible for (对…负责) the opening of that first mine.
     Mr. Johns was given a piece of asbestos which had been found in Italy. He experimented with the material
and then showed its surprising powers to his customers. After putting on a pair of asbestos gloves, which
looked much like ordinary work gloves, he took red-hot coals from the fireplace and played with them in his
hands. How astonished the customers were to discover that he was not burned at all.You can well imagine that
he had increasing business in asbestos roofing materials. However, because it was very expensive to transport
(carry) them from Italy to the United States, Mr. Johns sent out a young scientist to seek a source nearer home.
This young man found great vein (岩脉), in the province of Quebec in Canada.
    Ever since 1881 Quebec has led the world in the production of this unusual mineral, which is made up of
magnesium, silicon, iron, and oxygen.When it is mined, the asbestos is heavy, just as you would expect a
mineral to be. When it is separated, a strange thing happens; the rock breaks down into fine, soft, soapy
fibres (纤维).
    Scientists do not know why the rock can be separated easily into threads (线), but they have found
thousands of uses of this fireproof material, of the so-called "cloth of stone". 1. Which title best expresses the main idea of this passage? [     ]
A. Asbestos mined in Canada
B. Fireproof matter
C. A "wonder" mineral
D. A new roofing material 2. Johns proved his ability as a salesman by _____. [     ]
A. going into roofing business
B. carrying asbestos from Italy
C. sending a trained scientist
D. showing the use of asbestos gloves 3. Which is the most important character of asbestos that the author wants to show us? [     ]
A. It is like thread.
B. It feels soapy.
C. It burns easily.
D. It is unusually heavy. 4. The author"s main purpose in writing this passage was to _____. [     ]
A. show the need for more scientists
B. compare asbestos with other minerals
C. increase the sales of asbestos
D. present facts about asbestos

Reading comprehension.

    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 easy 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 young 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 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.

1. The purpose of this passage is to _____. [     ]
A. explain how to use the Internet
B. describe the writer"s joy of keeping up with the latest technology
C. tell the merits (价值) and usefulness of the Internet
D. introduce the reader to basic knowledge about personal computers and the Internet 2. 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 3. 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 telephone
D. get in touch with one"s friends faster than the telephone 4. The best title for this passage is _____. [     ]
A. Computer: New Technological Advances
B. Internet: New Tool to Maintain Good Friendship
C. Computers Have Made Life Easier
D. Internet: a Convenient Tool for Communication

阅读理解。    Wild animals seem to have escaped the Indian Ocean tsunami (海啸), adding weight to
ideas they possess a "sixth sense" for disasters, experts said on Thursday.
    Sri Lanka wildlife officials have said the giant waves that killed over 24,000 people
along the Indian Ocean island"s coast seemingly missed wild beasts, with no dead animals
found.
    "No elephants are dead, not even a dead hare or rabbit. I think animals can sense
disaster. They have a sixth sense. They know when things are happening," H.D. Ratnayake,
deputy director of Sri Lanka"s Wildlife Department, said on Wednesday.
    The waves washed floodwaters up to 3 km (2 miles) inland at Yala National Park in the
southeast, Sri Lanka"s biggest wildlife reserve and home to hundreds of wild elephants.
"There has been a lot of evidence about dogs barking or birds migrating before volcanic
eruptions or earthquakes. But it has not been proven," said Matthew van Lierop, an animal
behaviour specialist at Johannesburg Zoo.
    "There have been no specific studies because you can"t really test it in a lab or
field setting," he said.
    Other authorities agreed with this conclusion.
    "Wildlife seem to be able to pick up certain phenomenon, especially birds. There are
many reports of birds detecting coming disasters," said Clive Walker, who has written
several books on African wildlife.
    Animals certainly rely on the known senses such as smell or hearing to avoid danger
such as predators (食肉动物).
    The idea of an animal "sixth sense" is a lasting one that the evidence on Sri Lanka"s
damaged coast is likely to add to. 1. This passage is mainly about ______. [     ]
A. the damage that was caused in the Indian Ocean tsunami
B. why animals can save them from natural disasters
C. how to protect the wildlife when disaster happens
D. the different opinions about animals" natural power 2. Which of the following is true according to the text? [     ]
A. It has been proved that animals have a "sixth sense".
B. Research has been made on the special movements of animals before disasters.
C. It"s generally considered that animals can sense the coming of disasters.
D. Animals have depended on the known senses to escape the Indian Ocean tsunami. 3. What does the term "sixth sense" in the text means? [     ]
A. It is the natural ability of animals that can save them from danger.
B. It is the animal"s imagination in the brain.
C. It is some hidden power to say in advance that something will happen.
D. It is a kind of sense that is the same as smell or hearing. 4. Which section does the text most probably appear in a newspaper? [     ]
A. News Report.
B. Discovery.
C. Science Fiction.
D. Culture.

阅读理解。    We often hear people say, "I have a good memory for things like that" or "I can remember
names". But do you know memory is the single most important thing and it has played a very
important part?
    For early men, there were dangerous all around them-bad weather, wild animals. The keys
to keep on living lay in man"s ability to remember these dangers and the ways he had dealt with
them in the past. In order for memories to be stored, the human brain became more complex.
And as man learned how to deal with them, he became civilized (文明).Surprisingly, scientists
today understand little about memory and how it works. They havenot yet found a way to open
up the brain and observe its function without destroying it. Perhaps there are two types of
memory: short-term and long-term. Short-term refers to those facts that stay with us for a few
seconds to a few hours. For instance, when you stay at a hotel, you remember the room number
and forget as soon as you leave. Long-term memory, on the other hand, means you remember
things for a long period of time. If you spend your honeymoon in a particular hotel, it"s likely that
you"ll remember your stay quite clearly.
    Scientists also believe that a short-term memory can become a long-term memory through
consolidation (巩固). A lot of chemical and physical changes take place in the part of the brain.
Although the human brain weighs three pounds, it contains 30 billion nerve cells (神经细胞) acting
like a computer. When those changes strengthen the links (联系) in certain nerve cells, a though
becomes a part of the long-term memory. 1. According to the author, without the development of man"s memory there would be _____. [     ]
A. no modern world
B. no recorded history
C. no animals
D. no dangers 2. Scientists" knowledge about the function of brain is _____.[     ]
A. interesting
B. not enough
C. great
D. encouraging 3. Short-term memory can change into long-term memory on condition that _____. [     ]
A. memory is good
B. it acts like a computer
C. people do more exercise
D. the links in nerve cells are strengthened by certain changes 4. So far the great discovery scientists have made about the function of brain is _____. [     ]
A. the weight of brain
B. two types of memory
C. 30 billion nerve cells
D. chemical and physical changes
