In July 1994 Jupiter, the largest planet in our solar system, was struck by 21 pieces of a comet (彗星). When the fragments (碎片) landed in the southern part of the giant planet, the explosions(爆炸) were watched by scientists here on the earth. But what if our own planet was hit by a comet?

 The year is 2094. It has been announced that a comet is heading towards the Earth. Most of it will miss our planet, but two fragments will probably hit the southern part of the Earth. The news has caused panic.

 On 17 July, a fragment, four kilometers wide, enters the Earth's atmosphere with a huge explosion. About half of the fragment is destroyed. But the major part survives and hits the South Atlantic at 200 times the speed of sound. The sea boils and an enormous(巨大的) wave is created and spreads. The wall of water rushes towards southern Africa at 800 kilometres an hour. Cities on the African coast are totally destroyed and millions of people are drowned. The wave moves into the Indian Ocean and heads towards Asia.

 Millions of people are already dead in the southern part of the Earth, but the north won't escape for long. Tons of broken pieces are thrown into the atmosphere by the explosions. As the sun is hidden by clouds of dust, temperatures around the world fall to almost zero. Crops are ruined. Wars break out as countries fight for food. A year later civilization has collapsed(崩溃). No more than 10 million people have survived.

 Could it really happen? In fact, it has already happened more than once in the history of the Earth. The dinosaurs were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a space fragment. The dinosaurs couldn't survive in the cold climate that followed and they became extinct. Will we meet the same end?

1.Which of the following is NOT TRUE according to the author's description of the disaster in 2094?

A. The whole world becomes extremely cold

B. All the coastal cities in Africa are destroyed

C. The visit of the comet results in wars

D. The whole mankind becomes extinct

2.Why does the author mention dinosaurs at the end of the passage?

A. Because they could only live in the warm climate

B. Because their extinction indicates future disasters

C. Because they once dominated(控制) the earth

D. Because dinosaurs and humans never live in the same age

3. In writing the passage, the author intends to ______.

A. give an accurate description of the possible disaster in the future

B. prove that humans will sooner or later be destroyed

C. warn of a possible disaster in the future

D. tell the historical development of the Earth

We are all busy talking about and using the Internet but how many of us know the history of the Internet?
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, the whole network stopped. So a new 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.
