第4题
As a rocket leaves the Earth, the pull of the Earth on it becomes less and less as the rocket roars out into space. If you imagine a line between the Earth the pull of the Earth and the moon, there is a point somewhere along that line, nearer to the moon than to the Earth, at which the gravitation pull of both the Earth and the moon on an object is just about equal. An object placed on the moon side of that point would be drawn to the moon. An object placed on the Earth side of that point would be drawn to the Earth. Therefore, a rocket need be sent only to this "point of no return" in order to get it to the moon. The moon's gravity will pull it the rest of the way.
The return trip of the rocket to Earth is, in some ways, less of a problem. The Earth's gravitational field reaches far closer to the moon than does the moon's to Earth. Thus it will be necessary to fire an Earthbound rocket only a few thousand miles away from the moon to reach a point where the rocket will drift to earth under the Earth's gravitational pull.
The problem of rocket travel is not so much concerned with getting the rocket into space as it is with guiding the rocket after it leaves the Earth's surface. Remember that the moon is constantly circling the Earth. A rocket fired at the moon and continuing in the direction in which it was fired would miss the moon by a wide margin and perhaps continue to drift out into space until "captured" in another planet's gravitational field. to reach the moon, a rocket must be fired toward the point where the moon will be when the rocket has traveled the required distance. This requires precise calculations of the speed and direction of the rocket and of the speed and direction of the moon.
For a rocket to arrive at a point where the moon's gravity will pull it the rest of the way, it must reach a speed called velocity of escape. This speed is about 25, 000 miles per hour. At a speed less than this, a rocket will merely circle the Earth in an orbit and eventually fall back to Earth.
This passage deals mainly with ______ .

B．the factors involved in firing a rocket into the outer-space
C．the gravitational fields of the Earth and the moon
D．the speed and direction of a rocket traveling in the outer-space
第5题
As few visitors have their own cars, renting one is the next best thing. You will need a valid driver's license and either international credit cards, or a deposit.
You should start out with a working knowledge of the road. Regulations vary from state to state and this can be very confusing to a newcomer. For example, in some states it is legal to turn right at a red light if there is no approaching traffic, while in other states you will be fined for this action. Throughout the country it is forbidden to pass a school bus when it has stopped to let off children.
The size of the country may startle you at first and you may be surprised at the spectacular physical beauty. When the first pioneers began to expand west into the wildness, the natural resources of the land seemed inexhaustible. Nearly 1,000 million acres of land was covered by virgin forest. Much of this was burnt off for farmland and it soon became apparent that the government would have to take action or the natural beauty of the land would be lost forever.
