      As the Internet becomes more popular, many older media (媒体) businesses are dying out. But
TV seems to be doing OK. In fact, it's doing better than OK. Though the Internet is popular in the
world, television continues to draw more and more people all over the world to many of its programs.
Hundreds of millions turn to TV to watch World Cup soccer,Olympic Games and Discoveries.
      In many places, increasing numbers of people can watch more TV than before. Ten years ago,
only 44% of British homes had satellite or cable TV(卫星或有线电视).Today, more than 93% do.
More importantly, recent studies show that people are spending more time watching TV. Surprisingly,
this is even true of young people between the ages of 8 and 18.Today's television industry has given so
many choices. As a result, people can watch more of the things they like 24 hours a day.
     The technology behind television has also improved. The big boxes that once filled living rooms are
gone. Today's TV screens are thinner and thinner, yet the pictures are better and better. TVs are also
moving from living rooms into kitchens and vehicles.
     For years, TVs have also been used as video game players. But now they have been used in a few
new ways. Many televisions can connect to the Internet and record programs. They also let people
watch two programs at the same time. Today the most modern television has been on the way of
development.
     The Internet is the main challenge (挑战) for television now. But TV industry has shown that
television will be important for years to come.

     Do you know why different animals or pests have their special colors? Colors in them seem to be
used mainly to protect themselves.
     Some birds like eating locusts (蝗虫) , but birds cannot easily catch them. Why? It is because
locusts change their colors together with the change of the colors of' crops. When crops are green,
locusts look green. But as the harvest time comes, locusts change to the same brown color as crops
have. Some other pests with different colors from plants are easily found and eaten by others. So they
have to hide themselves for lives and appear only at night.
    If you study the animal life, you'll find the main use of coloring is to protect themselves. Bears, lions
and other animals move quietly through forests. They cannot be easily seen by hunters. This is because
they have the colors much like the trees. They can often hide in the trees and catch some other little
animals.
    Have you ever noticed an even stranger act? A kind of' fish in the sea can send out a kind of very
black liquid when it faces danger. While the liquid spreads over, its enemies cannot find it. And it
immediately swims away. So it has lived up to now though it is not strong at all.
1. Frorn the passage we learn that locusts _____.
A. are small animals

3. Why can't the hunters see the bears and lions?
A. They have the colors much like the trees.
B. They move quietly.
C. They like brown and gray colors.
D. They live in forests.
4. Why can the kind of fish live up to now?
A. Because it is very strong.
B. Because the liquid it sends out can help it escape from its enemies.

       On June 26, 2000, two scientists, called Francis Collins and Craig Venter, told the world that they
could now read the whole "map" of the human body: DNA. DNA is something that everybody has, and
it tells the body what to do. DNA is the reason that we look like our mother and father, because we get
some of their DNA to make our own.    
       People have been trying to understand the human body for a long time. In 1860, Gregor Mendel
discovered a special reason why we look the same as other people in our family. It is because of small
things named "genes" in our body. In 1953, James Watson and Francis Crick made another discovery
and found out that those small parts are real messages written in the DNA with a special language.
       In 1961, Marshall Nirenberg and Johann Matthaei found a message in DNA showing how DNA
tells the cell (细胞) to build its parts. Scientists have now found all the words in the DNA map, but we
still do not understand what they all do. By understanding what just one "word" means, we can help
save more people from several illnesses.
       Most people hope that this will help make better medicine and help sick people. Other people worry
that when people begin to know more words and find out lots of other information, we might use it in a
wrong way, just to make people more attractive, or stop sick people from getting jobs. Man would have
to meet a lot of trouble if DNA technic wasn’t limited in use.

     Many people are surprised when they find that the Internet was set up in the 1960s. At that time,
computers were large and expensive. Computer networks didn't work well. If one computer in the
network broke down, then the whole network stopped. So a few network system had to be set up. It
should be good enough to be used by many different computers. If part of the network was not working,
information could be sent through another part. In this way computer network system would keep on
working all the time.
     At first the Internet was only used by the government, but in the early 1970s, universities, hospitals and
banks were allowed to use it, too. However, computers were still very expensive and the Internet was
difficult to use. By the start of 1990s, computers became cheaper and easier to use. Scientists had also
developed software that made "surfing" the Internet easier.
     Today it is easy to get on-line and it is said that millions of people use the Internet every day. Sending
e-mails is more and more popular among young people.
     The Internet has now become one of the most important parts of people's life.
1. How long has the Internet been used?
A. For about 10 years.  
B. For about 20 years.

was set up?

     Computers are very important to modern life. Many people think that in the future computers will be
used in lots of everyday life. It is thought that we won't have to go shopping because we will be able to
get most things sold in shops on the Internet. There will be no more books because we will be able to get
all texts (内容) from computers. The Internet will be used to play games, see films and buy food.Most
telephone calls will be made by computers, too.
     Some people are glad about these new ways of shopping and communicating (交际). Others do not
think that computers will replace (代替) our old ways.
     Let's look at books, for example, some people think that one day we will not read books made of
paper. Instead, we'll buy and read books using computers. We 'll read texts on small pocket computers.
The computers will keep many different books in them at the same time. We won't need to turn lots of
pages and paper will be saved.Computerized (计算机化) books will be used more and more.
     Is Internet shopping such a pleasure as going to the shop? Many people say it is not. It is a pleasure
to go into shops and look at things you want to buy. It is also unlikely (不太可能) that many people will
want to read large texts on our computers. Because paper books will perhaps be more friendly. Maybe
computers won't change these two habits (习惯).

A. playing games,shopping and making telephone calls
