Move Earth — it’s no science fiction

LONDON — Scientists have found an unusual way to prevent our planet from overheating: move it to a cooler spot. All you have to do is send a few comets（彗星）in the direction of Earth, and its orbit will be changed. Our world will then be sent spinning into a safer, colder part of the solar system.

This idea for improving our climate comes from a group of US National Aeronautics and Space Administration（NASA） engineers and American astronomers. They say their plan could add another six billion years to the useful lifetime of our planet—effectively doubling its working life.

The plan put forward by Dr Laughlin, and his colleagues Don Korycansky and Fred Adams ,needs carefully directing a comet or asteroid so that it passes close by our planet and sends some of its gravitational energy to Earth.

“Earth’s orbital speed would increase as a result and we would move to a higher orbit away from the Sun,” Laughlin said.

Engineers would then direct their comet so that it passed close to Jupiter or Saturn. The comet would pick up energy from one of these giant planets. Later its orbit would bring it back to Earth, and the process would be repeated. In the short term, the plan provides an ideal way to global warming, although the team was actually concerned with a much greater danger. The sun is certain to heat up in about a billion years and so “seriously compromise” our biosphere（生物圈）— by cooking us.

That’s why the group decided to try to save Earth.

The plan has one or two worrying aspects, however. For a start, space engineers would have to be very careful about how they directed their asteroid or comet towards Earth. The smallest miscalculation（誤算）in orbit could fire it straight at Earth—with deadly consequences.

There is also the question of the Moon. As the current issue of Scientific American magazine points out, if Earth was pushed out of its current position it is “most likely the Moon would be stripped away from Earth,” it states. This would greatly change our planet’s climate.

What makes the scientists plan to move Earth?

A. A few comets are moving to the direction of Earth.

B. Earth’s working life is coming to an end soon.

C. Earth will become too hot for mankind to keep alive.

D. The moon is moving farther and farther away from Earth.

If the plan is successful, Earth will have a working life of ______years.

A.12 billion                  B.6 billion                    C.18 billion                  D.24 billion

What serious problems might the plan cause according to the passage?

A. The comet might hit Earth and man might lose the moon.

B. Earth might be moved too far away and man might be frozen to death.

C. The comet might hit Jupiter or Saturn and never return to Earth.

D. Earth’s working life might be greatly shortened.

What does the underlined word “compromise” mean?

A. provide                    B. benefit                   C. share                     D. endanger

Which of the following best shows how the plan would work?

magician, Liu Qian, discovered it, in front         

of an audience of millions at CCTV’ s Spring

Festival Gala. Liu’ s magic tricks have made the centuries-old art of magic fashionable once again, and made him the hottest magician in China.

As a seasoned young magician from Taiwan, Liu is popular worldwide for his magic shows. Countries he has performed in include the U

nited States, Japan, South Korea and the UK.

 Witnessing something impossible happen right before your eyes is the root of people’ s love for magic.

 Liu is known for his interaction(互動(dòng))with his audiences. He has a unique understanding of showmanship(演出技巧).

“It’ s actually thinking rather than one’ s manipulation（操作）skills; that is more important to achieving a successful magic show. We think carefully about how to design the shows creatively, to make them appear more interesting.  ”Liu said.

    Liu Qian’ s success dated back to his childhood. Born in 1976 in Taiwan, he found himself attracted to a magic toy in a shop when he was seven years old. At the age of 12, he won Taiwan’ s Youth Magic Contest, which was judged by the great American magician, David Copperfield.

Yet, Liu never planned on becoming a professional magician. He studied Japanese literature at university and only hoped to be an amateur  (業(yè)余的) magician in his spare time. However, his failure to find a proper job after graduation pushed him towards magic as a career.

    To refine his performing skills, he has performed on streets, roads and fields for passers-by, policemen and farmers.

     “Street shows are the biggest challenge for us magicians. We have to deal with unexpected situations and tough crowds, ” Liu said.

Although it was unexpected,the Chinese were warmly welcomed.The boat carried goods such as silk and tea as well as a number of gifts from the Emperor of China for the Queen of England.

People had always mistakenly thought of the Chinese as a people not used to sea.However,from centuries of trading and sailing in dangerous seas,the Chinese had learned how to build good boats and sailed them well.The coming of this sailing boat to London proved once again that the Chinese could sail to distant countries in the world.

Today, roller skating is easy and fun．But a long time ago, it wasn’t easy at all. Before 1750, the idea of skating didn’t exist. That changed because of a man named Joseph Merlin. Merlin’s work was making musical instruments. In his spare time he liked to play the violin. Joseph Merlin was a man of ideas and dreams. People called him a dreamer.

One day Merlin received an invitation to attend a fancy dress ball（化裝舞會(huì)）. He was very pleased and a little excited. As the day of the party came near, Merlin began to think how to make a grand entrance at the party. He had an idea. He thought he would get a lot of attention if he could skate into the room.

　　Merlin tried different ways to make himself roll. Finally, he decided to put two wheels under each shoe. These were the first roller skates. Merlin was very proud of his invention and dreamed of arriving at the party on wheels while playing the violin.

　　On the night of the party Merlin rolled into the room playing his violin. Everyone was astonished to see him. There was just one problem. Merlin had no way to stop his roller skates. He rolled on and on. Suddenly, he ran into a huge mirror that was hanging on the wall. Down fell the mirror, breaking to pieces. Nobody forgot Merlin’s grand entrance for a long time!
