读写任务。

阅读下面的短文,然后按照要求写一篇150词左右的英语短文。

     Scientists find that hard-working people live longer than average men and women. Career women are

healthier than housewives. Evidence shows that the jobless are in poorer health than the job-holders. A study

shows that whenever the employment rate increases by 1%, the death rate increase correspondingly (相应地)

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 and lonely when they have nothing to do. Instead, the happiest are

those who are busy. Work serves as a bridge between man and reality. By work, people come into contact

with each other. By collective activities, they find friendship and warmth. This is helpful to health. The loss

of work means the loss of everything. It affects man spiritually and makes him likely to disease. Besides,

work gives one a sense of fulfillment and a sense of achievement. Work makes one feel his value and status

in society. When a writer finishes his writing or teacher sees his students grow, they are happy beyond words.
