No one knows when the first kite was made. The first record of a kite was more than 2,000 years ago in China. Han Xin, the leader of an army, wanted to bring down a king. He decided to dig a tunnel (隊道）into the king’s palace. He flew a kite over the wall of the palace to make sure the length (長度）of its string (線).In this way, he could determine how long the tunnel should be.His men in the tunnel took the kite string with them. When they reached the end of the string, they knew to dig up.

Kites have been flown in Japan for hundreds of years. In the 1700s, kites were flown in autumn to give thanks for a good harvest. They were also flown to send good wishes to couples who had their first son. Today in Japan, kites are often flown as part of a celebration, such as the beginning of a new year. And kite festivals are held each year in many parts of the country.

Kites have been used for scientific purposes in the western world. In 1752，Benjamin Franklin tied a key to a kite and flew it in a storm to find out that lightening was a form of electricity. In the 1890s，Lawrence Hargrave invented the box kite to test ideas about flight. From 1898 until 1933，the United States Weather Bureau (氣象局） used box kites to collect weather data. The Wright brothers also experimented (試驗）with kites. What they learnt helped them make the first airplane flight in 1903.

Scientists find that hard-working people can live longer than idle(不工作的) people. Career women are healthier than housewives. Evidence shows that the jobless are in poorer health than the job-holder. A report shows that whenever the unemployment rate(失業(yè)率) increases by 1%, the death rate increases by 2%. All this comes down to one point: work is helpful to health.

Why is work good for health? It is because work keeps people busy, away from loneliness. Researches show that people feel unhappy, worried when they have nothing to do. Instead, the happiest are those who are busy. Many high achievers who love their careers feel that they are happiest when they are working hard. Work serves as a bridge between man and reality(現(xiàn)實). By work, people come into contact with each other. By taking part in some activities, they find friendship and warmth. This is helpful to health. The loss of work means the loss of everything. It affects man in spirit and makes him easy to get ill.

Besides, work gives one a sense of fulfillment(充實感) and a sense of achievement. Work makes one feel his value in society. When a writer finishes his writing or a doctor successfully operates on a patient or a teacher sees his students grow, they are happy beyond words.

From the above we can come to the conclusion that the more you work, the happier and healthier you will be. Let us work hard and study well and live a happy and healthy life.

1.Who can live longer, hard-working people or idle people?

________________________________________________________________

2.How do people feel when they don’t have anything to do?

________________________________________________________________

3.How can we find friendship and warmth in our daily life?

________________________________________________________________

4.Why can career women be healthier than housewives? (請根據(jù)文章內(nèi)容，自擬1句話作答)

________________________________________________________________

5.What do you think hard work can bring us? (請根據(jù)自己的想法，自擬1-2句話作答)
