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

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

My son and I were trying to sell the house we had repaired but in the barn(谷仓)there were bats(蝙蝠)and they would not leave. The barn was their home. They told us so in their own way. They hung there in the barn and seemed determined to stay for the season. Don’t worry about it, Dad, " Patrick said. They keep down the mosquitoes(蚊子).”

Unfortunately they also kept the buyers away. when we had asked a person to sell　the house for us he had refused to show it because of the bats. Bats are popular, “Patrick comforted me. They’re ecological(生态学的).”Isn’t there a machine you can buy that produces high frequency sounds to keep bats away?” “I don’t know,” said Patrick. But I like bats, and whoever buys this house will probably like them too. “Probably?” I hated that word. “How many bats are　there ,anyway?” “I counted about 90 last night,” said Patrick. “They were dropping out from under the edge of the roof.” “You mean there are more — outside?” “They’re everywhere, Dad. But look at it this way. When the cold weather comes, they’ll be off to Mexico. Maybe in the spring we can keep them out. Don’t worry about it,” he said for the hundredth time. “It’s not a problem.”

The bat expert I called was even more active than Patrick. I think you’ve got a large number there,” he said in wonder, I’ve been trying to attract bats to our house for 25 years. A single bat eats up his weight in mosquitoes and black flies three times every night. You’re a very lucky man.” I offered to share my luck with him. He could take them away. Bats have a remarkable homing instinct(本能),”he said, “They’d fly straight back even if I transported them 100 miles. Once they have settled, you can’t stop them from coming back.” I was silent.

Finally we managed to rent “(出租)the house to a young family, who were also interested in buying it. What about the bats?” I said to Patrick.

“Oh, they love the bats,” he said. “No mosquitoes. No black flies. It’s one of the things that attracted them.”

“Do you think they will really buy the blouse?”

“Probably.”

“Probably? Well, if they do ,I suppose I’ll have to admit that I was wrong.”

“You mean you’re going to eat your words?”

“Yes, I am.”
