We know that there is air all around the world. We could not breathe without air. Airplanes could not fly without air. Thy need air to lift their wings. Airplanes cannot fly very high because as they go higher the air gets thinner. If we go far enough away from the earth, we find there is no air. What is the sky？ The sky is space. In this space there is nothing except the sun, the moon and all the stars. Scientists have always wanted to know more about the other worlds in the space. They have looked at them through telescopes and in this way they have found out a great deal. The moon is about 384,000 kilometers away from the earth. An airplane cannot fly to the moon but there is a thing that can fly even when there is no air. This is rocket.
I am sure that you are asking, “How does a rocket fly？” if you want to know, get a balloon and then blow it up until it is quite big. Do not tie up the neck of the balloon. Let go! The balloon will fly off through the air very quickly. The air inside the balloon tries to get out. It rushes out through the neck of the balloon and this pushes the balloon through the air. It does not need wings like an airplane. This is how a rocket works. It is not made of rubber like a balloon, of course. It is made of metal. The metal must not be heavy but it must be very strong. There is gas inside the rocket which is made very hot. When it rushes out of the end of the rocket, the rocket is pushed up into the air.
Rockets can fly fat out into space. Rockets with men inside them have already reached the moon. Several rockets, without men inside them, have been sent to other worlds much father away. One day rockets may be able to go anywhere in the space.

Psychologists now believe that noise has a considerable effect on people's attitudes and behavior. Experiments have proved that in noisy situations(even temporary ones), people would have more anger and less cooperation; In more permanent noisy situations, many people cannot work hard, and they suffer from severe anxiety as well as other psychological problems. Some researchers, who study various aspects of effect of noise in people's mental life, maintain that noise, either temporary noise or permanent noise, often destroy creativity and activity by disturbing people's emotion and make them more easily annoyed and hard to cooperate.
However, psychologists distinguish between "sound" and "noise". "Sound" is measured physically in decibels(分贝). "Noise" cannot be measured in the same way because it refers to the psychological effect of sound and its level of "intensity" depends on the situation. Thus, for passengers at an airport who expect to hear airplanes taking off and landing, there may be a lot of sound, but not much noise(that is, they are not bothered by the noise). By contrast, if you are at a concert and two people behind you are whispering, you feel they are talking noisily even if there is not much sound. You notice the noise because it affects you psychologically.
Both sound and noise can have negative effects, but what is most important is if the person has control over the sound. People walking down the street with earphones, listening to music that they enjoy, are receiving a lot of decibels of sound, but they are probably happy hearing sounds which they control. On the other hand, people in the street without earphones must tolerate a lot of noise which they have no control over. It is noise pollution that we need to control in order to help people live more happily.
According to the passage, people （） .
A.can not complete his work in a noisy situation
B.will suffer from complete deafness because of noise pollution
C.can be psychologically affected by working in very noisy factories
D.may cooperate well in a noisy surrounding

ort, and convenience. These cars will float along never touching the ground, and therefore will have no need for wheels. Annoying highway vibrations, caused by the rotations of the disc-and-tire wheels, will be things of the past. The coming highway passenger cars will literally fly above the road, supported on columns of air compressed by
turbine-driven fans.
The car without wheels has been called a “flying car” , and, in a sense, that’ s just what it is; however, it will not back out of the family garage, start down the street, and then suddenly go quickly upward heading for some distant point. On the contrary, to avoid problems in aerial navigation, the wheel-less vehicle probably will travel no more than three inches above road surface. It will travel over fairly rough road and even over smooth water.
The inevitable problems of maritime regulations, severe weather conditions, and running out of fuel in remote areas all will require new concepts of operation, servicing, and vehicle regulation.
1.The author believes that cars of the future _______ .
A、will be replaced by airplanes

A、without annoying noise

West lake College in Virginia will start a laptop computer program that allows students to do school work anywhere they want. Within five years,each of the 1,500 students at the college will receive a laptop. The laptops are a part of a $10 million computer program at West lake, a 110-year-old college. The students with laptops will also have access to the Internet. In addition, they will be able to use e-mail to “speak”with their teachers, their classmates, and their families. However, the most important part of the laptop program is that students will be able to use computers without going to computer labs. They can work with it at home, in a fast-food restaurant or under the trees-anywhere at all!

As laptops become more powerful, they become more similar to desktop computers. In addition, the portable computers can connect students to not only Internet, but also libraries and other resources. State higher-education officials are studying how laptops can help students.
State Officials also are testing laptop programs at other universities,too.
At West lake College, more than 60 percent of the staff use the computers. The laptops will allow all teachers to use computers in their lessons.
