Hawking’s great interest has been to understand the basic laws that our universe follows. One of his most well-known achievements was to demonstrate, along with Roger Penrose, that Einstein’s theory of general relativity needed to be brought together with quantum theory. Hawking and Penrose showed that if Einstein’s theory was carried out logically, space and time must have begun in something like the “Big Bang” of evolutionary theory and must end in black holes.

Hawking has received numerous medals, awards and other prizes for his work. He is known today not only among professional scientists but also by the general public. He has published several books specially written to try to explain his theories to the common man. Three of his most popular books are his bestsellers A Brief History of Time, Black Holes and Baby Universes and Other Essays and most recently in 2001, The Universe in a Nutshell. Hawking continues to research and write, not letting his disabilities slow him down. His goal is simple, he says. He simply wants “a complete understanding of the universe. Why it is as it is and why it exists at all.” 1. Stephen Hawking is arguably the most famous scientist because _____. A. he is the only one who is alive today B. he is totally disabled

C. he can not only understand but explain complex theories in simpler ways D. he has received numerous medals 2. The underlined sentence probably means ______.

A. he studied physics instead of mathematics because the degree studies weren’t provided B. he couldn’t afford to study at University College

Two China astronauts, Fei Junlong and Nie Haisheng, are safely back on earth after their Shenzhou 6 spacecraft successfully touched down on the grasslands of Inner Mongolia Sunday at 4:32:50 pm, ending a five-day mission and China’s second manned space flight.

“I want to thank the people for their love and care,” Fei said during the ceremony, in which both astronauts were given flowers and seated in chairs.

The Shenzhou 6 crew spent 115 hours and 32 minutes in space, and travelled 2 million miles (3.25 million kilometres) during their mission, which set new human spaceflight records for China.

Fei and Nie were sent into space on October 12th, Beijing time on China’s second manned spaceflight, the first to carry two astronauts. The spaceship lifted off from Jiuquan Satellite Launch Centre in the Gobi desert almost two years to the day after China’s first manned launch.

That first mission, Shenzhou 5, launched astonaut Yang Liwei into orbit on October 15th, 2003, China is the third country to independently launched humans into Earth orbit after Russia and the US. But unlike Yang’s flight, which the public did not get to see much of, much of Shenzhou 6 mission from lift-off to landing was shown live on national Chinese television. With Shenzhou 6, China has “achieved another milestone … in … space exploration,” said Wu Bangguo, Chairman of the Chinese NPC during his speech which was broadcast live on CCTV.

6. In which year was Shenzhou 6 launched into space? A. 2003. B. 2004 C. 2005 D. 2006. 7. What was the speed of Shenzhou 6 when it was travelling into space?

A. 28,130 kilometres per hour. B. 28,130 miles per hour. C. 35,540 kilometres per hour. D. 35,540 miles per hour.

8. Which of the following countries has not succeeded in launching humans into Earth orbit? A. China. B. Russia. C. The US. D. The UK. 9. Which of the following statements is NOT true?

A. Shenzhou 6 landed on grasslands of Inner Mongolia Sunday at 4:32:50 pm. B. The Shenzhou 6 crew spent 115 hours and 32 minutes in space.

C. The Shenzhou 6 crew set new human spaceflight records around the world. D. Yang Liwei’s flight was not shown live on national Chinese television. 10. Which one is the best title of this passage?

A. Shenzhou 6’s Safe Return B. History of China’s Space Exploration C. New Human Spaceflight Records D. Chinese Astronauts

In July 1994 Jupiter, the largest planet in our solar system, was struck by 21 pieces of comet(彗星).When the fragments(碎片)landed in the southern part of the giant planet, the explosions were watched by scientist 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 waves 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 believed 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?

11. Which of the following in 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 whole mankind becomes extinct. D. The visit of the comet results in war. 12. Why does the author mention dinosaur at the end of the passage?

A. Because they could only live in the warm climate. B. Because they once dominated the earth.

C. Because their extinction indicates future disasters. D. Because dinosaurs and humans never live in the same age 13. 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. tell the historical development of the earth D. warn of a possible disaster in the future 14. It can be concluded that the passage is most probably part of a(n) ____. A. horror storyB. news report C. research paper D. article of popular science

Edmund Halley was an English scientist who lived over 200 years ago. He studied the observations of comets(彗星)which other scientists had made. The orbit of one particular comet was a very difficult mathematical problem. He could not figure it out. Neither could other scientists who dealt with such problems.

However, Halley had a friend named Isaac Newton, who was a brilliant mathematician. Newton thought he had already worked out that problem, but he could not find the papers on which he had done it. He told Halley that the orbit of a comet had the shape of an ellipse(椭圆形).

Now Halley set to work. He figured out(解决，计算出)the orbits of some of the comets that had been observed by scientists. He made a surprising discovery. The comets that had appeared in the years 1531, 1607, and 1682 all had the same orbit. Yet their appearance had been 75 to 76 years apart.

This seemed very strange to Halley. Three different comets followed the same orbit. The more Halley thought about it, the ore his thought that there had been three different comets as people thought. He decided that they had simply seen the same comet three times. The comet had gone away and had come back again.

It was an astonishing idea! Halley felt certain though to make a prediction(预言)of what would happen in the future. He decided that this would appear in the year 1758. There were 53 years to go before Halley’s prediction could be tested. In 1758 the comet appeared in the sky. Halley did not see it, for he had died some years before. Ever since then that comet had

17

been called Halley’s comet, in his honor.

15 Edmund Halley figured out the orbit of ____.

A. some different comets appearing several times B. the same comet appearing at different times C. three different comets appearing at the same time D. several comets appearing at the same time 16. Halley made his discovery ____.

A. by doing experiments B. by means of his own careful observation C. by using the working of other scientists D. by chance

17. Halley made a surprising, but correct prediction in the year____. A. 1704 B. 1705 C. 1706 D. 1707 18. This passage in general is about ____.

A. Halley and other scientists B. the orbit of a comet C. Newton and Halley D. Halley and his discovery 19. Which of the following is TRUE?

A. Edmund Halley was an American scientist. B. Halley made his discovery by doing experiments. C. Isaac Newton was a famous mathematician. D. The orbit of a comet had the shape of an around.
