阅读理解:

  The Earth has a force that pulls things toward itself. We call this force gravity(引力). This is something we love with all the time, and hardly ever think about it. But it is a most important factor(因素)in rocket(火箭)operation and must be overcome if we are to get anywhere in space, or off the ground at all.

  Take the throwing of a ball as an example. The harder the ball is thrown, the faster and higher it will go. What is the secret? Its speed. If we could throw the ball hard enough it would go up and up and up forever and never come down. The speed at which it would have to be thrown to do this is known as escape speed. Of course, we cannot throw a ball hard enough because the speed required to escape completely from the Earth’s gravity is seven miles per second, or over twenty-five thousand miles per hour.

  Once escape speed has been reached by a spaceship, no further power is needed. A rocket aimed at the Moon, for instance, will “:coast”(滑行)the rest of the way because the Earth’s gravity cannot then pull it back, and there is no air resistance in space to slow it down. This “coasting” is known as “free fall”. That does not mean the rocket is falling down towards the Earth but that it is travelling freely in space without the help of power, like a bicycle coasting downhill.

  Free fall is an important feature of space travel: it would be impossible to carry enough oil to supply powered flight all the time.

1What is the most important factor for a rocket to escape from the Earth?  

 [  ]

ATo travel as fast as it can.

BTo overcome the Earth’s gravity.

CTo get away from the air resistance.

DTo have strong power in its operation.

2How fast will a rocket escape completely from the Earth’s gravity?

 [  ]

ASeventy miles per second.

BSeven thousand miles per hour.

CTwenty-five thousand miles per second.

DTwenty-five thousand miles per hour.

3As there is always the Earth’s gravitational pull, people ______.

[  ]

Aaccept it without questioning it

Bnever feel interested in its presence

Chardly think about how to use it

Doften try to escape from it

4When a bicycle “coasts” downhill, it ______.

   [  ]

Aruns along the hillside

Bdoes not need any further power

Cruns freely in all directions

Ddoes not meet with air resistance

5It’s unnecessary to supply power for the flight in space all the time, because ______.

   [  ]

Afew spaceships complete their flight operations

Bthe Earth’s gravity cannot be overcome

Cno further power is needed after the escape speed is reached

D“free fall” takes the place of the Earth’s gravity

  When a tornado(龙卷风) destroys a house, it doesn’t blow it down the way a hurricane(十二级台风) does. It makes the house explode. Why does the house explode?

  The air that surrounds a house presses against it all the time. It usually has a force of about fifteen pounds per square inch. The air inside the house presses out against the walls just as hard. When a tornado passes over a house, it suddenly sucks away the air outside the house. The air inside the house still pushes out against the walls, but now there is nothing pushing back. So the walls are pushed out in an explosion.

  Pieces of the house are sucked up into the tornado and carried away. There is little left where the house once stood.

1A tornado makes a house ______.

 [  ]

Aexplode    Bblow away

Cfall down   Dcatch fire

  The early settlers who came from the eastern United States were used to having lots of trees around. They found it hard to live in a treeless place like Nebraska.

  Even at the age of 89 Rene Huyghe still loves the woman with whom he spent World Wardriving her from her house to safety, hiding her in his office, even sharing a bedroom with her. She was “Mona Lisa”, masterpiece of Leonardo da Vinci and a centerpiece of the Louvre. He was the chief curator(管理员)of paintings there.

  Foreseeing the Nazi drive across Europe, Huyghe began planning in 1938 to hide his charges. When Germans entered Poland a year later, Huyghe’s trucks took Louvre paintings to hiding places far from Paris. “Mona Lisa” rode in a car, “always going with a curator, sometimes with me,” he recalls.

  She was carried from place to place out of fear. Bombs could strike her hiding place; fire could burn her; she could end up in a German collection.

  Once, as Nazi troops passed her last hiding place, Chateau de Montal, a Resistance fighter inside fired at them. Fearing retaliation(报复), Huyghe shouted to the man, “You are mad! Stop it at once!” The troops moved on and the following day razed(洗劫) entire village nearby.
