In July 1994 Jupiter, the largest planet in our solar system, was struck by 21 pieces of a comet(彗星). When the fragment(碎片)landed in the southern part of the giant planet, the explosions were watched by scientists here on 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 wave is created and spreads. The wall of water rushes towards southern Africa at 800 kilometers 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. 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(恐龙)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?

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

MIANYANG—At a corner of the city’s Jiuzhou Stadium, one of the biggest camps set up for those left homeless in the earthquake, 62-year-old Liu Yaorong was leaning against a window on Thursday.

Pointing to a quilt and clothes he received from the local government, he said: “These are all I have. My home collapsed in the quake, and everything in the town was flooded.”

He used to live in Xuanping town of Beichuan county which was destroyed by the quake. Adding to his misery, rivers blocked by landslides(山崩) led to flooding in the town.

But Liu said he was lucky because he was healthy, otherwise he would not have the energy to walk 10 hours on damaged and dangerous mountainous roads to escape the flood on Monday. He said the trip used to take him about 90 minutes when the roads were in good condition.

The journey was difficult and “rocks kept falling,” he said, showing injured legs and black, split toenails.

Liu said his three sons were working in eastern cities as migrant workers.

“I’ve been living alone in the mountains for more than 20 years. My wife died 30 years ago,” he said in a low voice.

During his journey to Mianyang, Liu said he saw many elderly people who chose to stay.

“Soldiers were persuading them to leave for fear of floods,” he said.

Talking about his home before the quake struck, Liu’s mood lifted. “I raised pigs and chickens, and grew vegetables. I could have rice, meat and greens almost every day,” he said.

“But now, I have only biscuits and instant noodles.”

Liu said one of his sons returned home from Wenzhou, Zhejiang Province, after the quake, but left because the father refused to go with him.

“I don’t want to leave home. And I know it is difficult for them out there. How could I add to their burden?” he asked, his eyes red.

“I still want to go back to my home. Given a small piece of land, I could live by myself.”

It is learnt that resettlement plans for displaced people have not been finalized.

However, not every elderly person is as strong-willed as Liu.

Psychologists said the elderly need as much comfort as children. Lu Jianguo, a psychologist from Chengdu Medical College, said “We will first let them cry and tell their stories, and then help them regain confidence.”

Which of the following is TRUE according to the passage?

A. Liu Yaorong spent 8.5 hours more than usual covering the roads in escaping the flood.

B. The flood was followed by an earthquake in Xuanping in the same day.

C. Liu Yaorong was in time to escape the quake without being hurt.

D. Being healthy, Liu Yaorong was the only old man to escape the flood.

The underlined word “ misery  ”in the third paragraph most probably means “       ”.

A. happiness          B. fortune      C. puzzle          D. suffering

What’s Liu Yaorong’s attitude towards self-relief after the earthquake?

    A. Positive.         B. Negative.       C. Aggressive.       D. Dependent.

What would be the best title for the news report?

A. Elderly react more quickly to flood disaster

B. Elderly try hard to deal with quake disaster

C. Elderly prefer to stay at their own home

D. Elderly are well cared for by government

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余项。

     Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly similar pattern is passed on from parents to children, though nobody knows why this is the case.

    The ridge (隆起) structure on a person's fingers does not change with growth and is not affected by surface injuries. Burns, cuts and other damage to the outer part of the skin will be replaced in time by new one, which bears a reproduction of the original pattern.    Some criminals make use of this fact to remove their own finger-prints but this is a dangerous and rare step to take.

     Finger-prints can be made very easily with printer's ink. They can be recorded easily.        Because of the simplicity and economy of this system, finger-prints have often been used as a method of solving criminal case. A suspected man may deny a charge but this may be in vain.      When a suspect leaves finger-prints behind at the scene of a crime, they are difficult to detect with the naked eye.

        Some of the marks found are incomplete but identification is possible if a print of a quarter of an inch square can be obtained.

A. Special techniques are used to "develop" them.

B. A fingerprint is an impression of the friction ridges of all part of the finger.

C. It is only when the inner skin is injured that the arrangement will be destroyed.

D. With special methods, identification can be achieved successfully within a short time.

E. This is called a latent print.

F. His finger-prints can prove who he is even if his appearance has been changed by age or accident.

G. Every human being has a unique arrangement of the skin on his fingers and this arrangement is unchangeable.
