閱讀下面短文，然后根據(jù)短文內(nèi)容回答問題。

　　When we think of money, we think of coins and paper bills. That is what money is today. But in the past people used many things instead of money. Some countries used cows. Other countries used salt, tobacco(煙草), or stones. Today there are still some places in the world that do not use paper money. One place is the island of Yap in the Pacific Ocean.

　　On the island of Yap, people use the heaviest money in the world－Yap stones. These are round, white stones with a hole in the middle. The Yap stones do not originate(起源) from the island. The Yap men have to go to islands four hundred miles away to get them. Big stones can be twelve feet high－as big as two tall men. Small stones are as big as a dinner plate.

　　Rich people do not carry the Yap stones. Servants(仆人) Follow the rich. Each servant carries a stone on a long stick over his shoulder(肩膀). Today the people on the island use paper money for everyday shopping. But for other things they still prefer Yap stones.

1．What is money today?

2．What did people use instead of money in the world in the past?

3．Where do people on the island of Yap get Yap stones?

4．What do Yap stones look like?

5．What do the Yap men buy with Yap stones today?

Reading comprehension(閱讀理解)

　　Parents whose children show a special interest in a particular sport have a difficult decision to make about their children's careers(職業(yè)). Should they allow their children to train to become top sportsmen and women? For many children it means starting very young and schoolwork, going out with friends and other interests have to take second place. It's very difficult to explain to a young child why he or she has to train for five hours a day, even at the weekend, when most of his or her friends are playing.

　　Another problem is of course money. Only the very best young sportsmen and women can get some money from the government. In most cases, it is the parents who have to find the time and the money to support their child's training－and sports clothes, transport to competitions, special equipment can all be very expensive.

　　Many parents are worried that it is dangerous to start serious training in a sport at an early age. Some doctors agree that young muscles(肌肉) may be damaged by training before they are properly developed. Professional trainers(職業(yè)訓(xùn)練師), however, believe that it is only by starting young that you can reach the top as a successful sports person. What is clear is that very few people do reach the top and both parents and children should be prepared for failure even after many years of training.

Complete the answer to each question(根據(jù)短文內(nèi)容完成下列問題的答案)

1．How do the government help young people who are good at sport?

It gives money to the very best ________ ________ ________ ________.

2．What are the advantages(好處) of early training? Name one.

3．What are the disadvantages(壞處) of early training? Name three.

1) It's ________ ________.

2) You won't have much time for ________, ________ ________ ________ ________.

3) You may ________ ________ ________.

4．What should both parents and children be prepared for?

They should be prepared for ________ even after ________ ________ ________ ________.

　　Clem Quinn was always interested in flying.

You can see forever, all the way to the French coast(海岸). The scenery is beautiful. You can forget all your worries. People think it is dangerous but it's very safe. Football is much more dangerous. Footballers often have accidents. When did you last hear of a sky-diving accident? Next July I'm going to do a sky-dive with 100 people from six planes. That's a record. I'm never going to give up. I'm going to jump out of planes until I'm an old man.”
