阅读下列短文，从每小题所给的四个选项中选出一个最佳答案。
The United States is not the only country affected by the “computer revolution ”. All the major countries of the world have computers, and the developing countries have also realized that computers play a big part in their economic development.
Usually what one sees is a machine that looks like a typewriter; it is called a computer terminal (终端). But computers are also used in unseen ways. For example. they determine how much time there should be between traffic signals to prevent traffic problems and to keep millions of cars moving in an orderly flow. When you buy a car, a factory process (过程) that is controlled by a computer enables you to obtain a car with your own choice of colors and special features(特征) in just a few weeks' time. In medical laboratories, computers have reduced the mistakes in testing, and they have saved doctors' countless hours of work. Before long, medical histories of all Americans will be kept in computer “banks”. If a person becomes ill far from his home, local doctors will be able to get his medical record immediately. In science, the computer has performed in minutes experiments which would have required thousands of hours of work by human hands and minds.
Most experts agree that computers are necessary to solve the problems of increasing population, city living, and public affairs. Without computers, the jobs of solving these problems would require millions of workers to do tons of paperwork. Before any computer can work on any problem, it must be told what to do. Someone must program the computer, step-by-step. At first this was done by having the programmer write out his instructions in the form of numbers which would be “understood” by the machine. Within a short time, attempts were made to perform a system that would enable humans to communicate more easily with machines. Different “languages” were developed by means of which the programmer could use words that had meanings for him, and another program in the machine would translate the words into the computer's number system.
Without special training, it is impossible to understand exactly how a computer does its work. However, many people without scientific training use computers in their daily lives. In some American schools, for example, young children are being taught by computers for part of the school day.
The use of computers in school has worried some Americans. There are those who fear it will remove human element (成分) from teacher-student relationships. On the other hand, there are educators who consider computer program a valuable means of freeing teachers from the more boring and tiring tasks, thus enabling them to spend more time with a single student.
In education, as in business and industry, science and medicine, computers play an important part in almost every type of operation. The future will bring major advances in computer technology, which will aid man in his efforts to improve the world.

Most people agree that there will be changes in the future. However, many people don't agree on what the changes will be, especially as we look further and further ahead.
One change that most people agree on is that the world will have more people, in part this is because of better health care. Older people will live longer, and fewer babies will die.
Another change that many people agree on is that oil products will cost more. Oil is a natural resource. We are beginning to use it all up. As we use up more oil, there will be less left in the world. That will make the remaining oil worth more money, so the remaining oil will cost its users more.
America built a spaceship. This spaceship will soon travel almost weekly between the earth and space just above earth’s atmosphere. America’s spaceship will change the way we view space travel. In the past, only a few highly trained people went into space, soon the spaceship will take many kinds of people and things. Room on the spaceship has even been bought for the science students in the Clear Creek School District near Houston, Texas. College students are going, too. Businesses are also planning to send workers and machines into space.
1．Which can be the best title of this story?
[ ]
A．Changes That Have Taken Place.
B．Changes That Are Coming Soon.
C．Changes Health.
D．Changes In Spaceship.
2．The world will have more people because ________ .
[ ]
A．the medical treatment will be better
B．older people will do more exercises
C．none of the newly-born babies will die
D．both the old and the young will have better food
3．The remaining oil will cost more money because ________ .
[ ]
A．it is important natural resource
B．cars, ships and planes use oil
C．there will be less oil for use
D．people like to use oil
4．“America’s spaceship will change the way we view space travel. ”“view”here means ________ .
[ ]
5．The spaceship will change the way we view space travel ________ into space.
[ ]
A．more trained people
B．more kinds of people and things
