    This hotel in the trees is famous in the world. People, who know very little about Kenya, know of Treetops. When King George VI died, Princess Elizabeth was staying on the Treetops, and when she came down from there, “She succeeded him as the queen of the country”. This hotel in the middle of the forest shows the pleasure of Africa. When you visit it, you will be sent into the heart of the forest by hotel buses, and then a guide, with a gun to protect you against big game, will go with you to the Treetops. Before and after dinner, for the whole night if you wish, you can sit on the corridor (走廊), watching animals come to the water pool. The earliest hotel Treetops was built round a large tree on the opposite side of the water, but that was destroyed by fire and the new hotel Treetops, which is built round several trees, is much bigger.

The dining room at Treetops is small, and the waiters cannot walk round to serve guests, a clever “railway service” has been invented. Guests take their food as it passes slowly in front of them, along a line in the center of the table.

There are many animals around the Treetops. When you visit them, you can see:

— Animals and their babies are waiting to greet the guests.

— Animals, enjoying the Treetops pool in the daylight.

— A long bodied, long ring tailed very active cat-like animal is a special one coming out at night.

He hunts and eats anything he can overpower, and his teeth and claws can do you harm.  

— Some other animals that have a thick coating of fur to keep them warm in the cold forest nights.

— Many buffaloes (水牛) coming near to the Treetops for water and salt during the day or night.

In Paragraph One, “succeeded” means ______.

A. did what she was trying to do            B. gained her purpose

C. got a position on the death of the King D. completed a difficult task

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(误算)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.

1. 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.

2.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

3.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.

4.What does the underlined word “compromise” mean?

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

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

Force other than damaging winds are also at work inside tornadoes. Sometimes, as the turning, jumping funnel(漏斗) passes over a house, the walls and ceiling burst apart as if a bomb had gone off inside. This explosion(爆炸) is caused by the low air pressure at the center of a tornado.

The pressure at the center of a tornado is usually 13 pounds per square inch. However, inside the house the air pressure is normal, about 15 pounds per square inch. The difference of 2 pounds per square inch between the inside and outside pressure may not seem like much. But suppose a tornado funnel passes over a small building that measures 20 by 10 by 10 feet. On each square inch of the building, there is 2 pounds of pressure from the inside that is not balanced by air pressure outside the building. On the ceiling, that adds up to an unbalanced pressure of 57,600 pounds. The pressure on the four walls adds up to 172,800 pounds.

If windows are open in the building, some of the inside air will rush out through them. This will balance the pressure inside and outside the building. But if the windows are shut tightly, the great inside pressure may cause the building to burst.

  Unfortunately, heavy rain happens in thunderstorms that later produce tornadoes. So, people often shut all windows to protect their property. This may cause far worse damage later.

63. Which of the following is the main topic of the passage?

A. Where tornadoes are formed.         B. When tornadoes usually occur.

C. How tornadoes can be prevented.       D. Why tornadoes cause so much damage.

64. According to the passage, tornadoes can destroy building because the _____.

A. force of a tornado increases the air pressure in a building

B. air pressure at the center of a tornado is over 172,000 pounds

C. weight of a tornado can crush a building’s roof when it passes overhead

D. air pressure inside a tornado is less than the air pressure inside a building

65. According to the passage, the pressure on a building during a tornado can be reduced    by _____.

A. closing the windows              B. opening the windows

C. using an electric fan               D. making the roof and walls stronger
