听力原文： Hi, there. Let me make a brief introduction of the brain first.

The brain tells the other parts of the body what to do. We think with our brain. We understand the world around us with our brain. However, doctors don't know much about how the brain works. Doctors can do many things with other parts of the body.

They can give a person a new heart. They can put an arm back on 'after it has been cut off. It is easy to study some parts of the body. However, it is difficult to know how the brain works. It is most difficult to work on a brain. If the brain is without enough blood for three to five minutes, the brain dies. So when doctors work on the brain, they only have three to five minutes to do their work] Doctors try new things on the brain, but they must be very careful. The brain is the center of those things that make us what we are.

Which of the following can't doctors do？

A．They can give a person a new heart.

B．They can give a person a new brain.

C．They can put an arm back on after it has been cut off.

听力原文： Villages in developing countries often lack many things: books, clean water and electricity. These shortages are easy to see, but a different kind of shortage is not easy to see. That is the shortage of experts.

Many villages have no doctors, engineers, or scientists. They have no one who knows how to treat unusual medical problems or design a new energy system. There is a way to solve these problems. They can do it with computers. In the past few years, computer scientists around the world have developed what they call expert system.

An expert system is a special kind of computer program. In some situations, it can take the place of human expert. For example, an expert medical system can help care for a sick person. A question appears on the computer screen "Is this person hot？" You tell the computer either "Yes" or "No". The computer asks other questions, "Has the person lost any blood？" "Can the person move normal[y？" you answer. The computer continues to ask questions until it has enough information to make a decision. Then it tells what medicine or other treatment is needed. In this way, the expert system takes the place of a doctor. Another kind of expert system takes the place of an engineer. It measures the flow of water in the river. It tells if a dam can be built on the river. It also tells how much electricity can be produced. Still other kinds of expert systems help solve problems for farmers and owners of small business.

B．Lack of electricity.

C．Shortage of experts.

D．Shortage of books.

Saving Money

Where you save your money often depends on what you are saving for. If you are saving to buy a CD (光盘) or to go to a concert, then probably you would keep your money somewhere in your room.＜br＞

If you are saving for a big purchase like a mountain bike or a school trip, where would you save your money？＜br＞

One place to save money is the bank. Putting your money in a savings account will help your money earn more money. If you put your money in a piggy bank (猪形储蓄罐) , one year later you&39;ll still have the same amount of money you put in. If you put your money in a savings account,one year later, you&39;ll have more money than you put in. Why？＜br＞

When you keep your money in a bank, your money earns interest. Interest is the amount of money a bank pays you to use your money. The bank uses your money (and the money of other people, too) to loan money to people and businesses.＜br＞

The bank will send you a statement several times a year. A bank statement tells you how much money you have in your. account. It also tells you how much interest you have earned. If you leave your money in the bank, you can watch it grow!＜br＞

Another way you can save money is to buy a certificate of deposit or CD. If you have some money that you don&39;t need to use for a long time, this is a good way to make your money grow.＜br＞

You can buy a CD at a bank. You agree not to use the money for a certain period of time. That period might be from six months to five years. You can&39;t touch your money during that time. If you do, you must pay a penalty, or fee.

Your money will earn more money if you put it__________. 查看材料

A.in your room

B.in a piggy bank

C.in your pocket

D.in a savings account
