2.　　　 What would happen if the gravity on Earth was suddenly turned off?

Supposing we could magically turn off gravity. Would buildings and other structures(建筑物) float away? What happened would depend on how strongly the things were attached to the Earth. The Earth is moving at quite a speed, moving at over a thousand miles per hours. If you turn something around your head on a string(细绳), it goes around in a circle until you let go of the string. Then it flies off in a straight line. ‘Switching off’ gravity would be like letting go of the string. Things not attached to the Earth would fly off in a straight line. People in buildings would suddenly shoot upwards at a great speed until they hit the ceiling. Most things outside would fly off into space.

Have you ever wondered?

1.　　　 Why do airplanes take longer to fly west than east?

It can take five hours to go west-east from New York(NY) to London bur seven hours to travel east-west from London to NY. The reason for the difference is an atmospheric phenomenon known as the jet(喷射) stream. The jet stream is a very high altitude wind which always blows from the west to the east across the Atlantic. The planes moving at a constant air speed thus go faster in the west-east direction when they are moving with the wind than in the opposite direction.

Passage 31

(北省黄冈市黄州区一中2010届高三第二次月考)

C

One kilogram--that was all it took to crown(给……加冕) the world's strongest man.

German weightlifter Matthias Steiner pulled ahead of Russian rival Evgeny Chigishev to win the Olympic men's +105 kg weightlifting gold medal on Tuesday.

Steiner lifted a total of 461kg, 203kg in the snatch(抓举) and 258kg in the clean and jerk(挺举), to beat Chigishev by a single kilogram. The German won the battle of giants in his last lift, winning his country's first gold medal in the event at this year's Games.

Steiner's winning lift was also the last effort of the sport for this Olympics at which China earned eight of the 15 golds.

Steiner was born in Austria and represented his country of birth at the Athens Olympics four years ago, placing seventh in the lower 105kg category, but had a falling out with Austria's weightlifting federation afterwards.

He applied for German citizenship in 2005 and got married, but his career went into deep freeze(困境)as he could not compete without a passport. He finally obtained the document last January.

The German, who turns 26 on Monday, had come to these Games on a mission to win the title for his wife Susann, who died in a car accident in July last year. The German team said he used the personal tragedy to motivate himself to win the gold medal.

Chigishev was the strongest in the snatch session Tuesday. He kissed his fists after a 210-kg lift that gave him a 7-kg advantage over fourth-placed Steiner going into the second event -- the clean and jerk. He let out a victorious roar after clearing 250 kg in his last lift, but the glory was short-lived as Steiner stunned(使瞠目)everyone with his final, winning clean and jerk effort.

Steiner had finished seventh in the 2004 Olympics in the 105kg weight category, and took the gold in the 2008 European Championship +105kg snatch competition, bronze in the clean and jerk and silver overall, with a total weight of 446kg.

World champion Viktors Scerbatihs of Latvia settled for bronze.
