It is important to have positive (積極的) feelings in our daily life.

Compared some unhappy people, those who are always pleased and relaxed are less likely to suffer from colds, a new study. The researchers from New York University said, “ helps the body prevent diseases.”

“It seems that positive feelings may reduce the of illness,” said the chief researcher Sheldon Cohen.

In an earlier study, Cohen found that people who were caught colds less often. And they seldom told their doctors that they felt .

In this study, Cohen’s team interviewed 193 adults every day for two weeks. In this , the people told researchers about happy or sad feelings that day. Two weeks later, all of them were made to catch colds by doctors, and they had to stay in a room for six days.

The results that each in the study was equal (平等的) to fall ill. people who were lively and relaxed said they felt happy during the research. Their illnesses were less serious and lasted for a time.

Cohen believes that people have positive feelings, their body may produce a kind of chemical that helps to illnesses. So if you your health, please look on the bright side and make yourself happy all the time

Green is an important color in nature. It is the color of grass and the leaves on trees. It is also the color of most growing plants.

Sometimes, the word “green” means young, fresh and growing. For example, a greenborn is someone who has no experience. In the 15 th century, a greenborn was a young cow or an ox whose borns(角)had not yet developed. A century later, a greenborn was a soldier who had no expericnce in war. By the 18 th century, a greenborn had the meaning it has today—a person who is new in a job.

Someone who is good at growing plants is said to have a green thumb(大拇指). The expression comes from the early 20 th century. A person with a green thumb can make plants grow quickly and well. The Green Revolution(綠色革命)is a name given some years ago to the development of new kinds of rice and other grains. It was the result of hard work by agricultural scientists who had green thumbs.

Green is also the color used to describe the powerful feeling, jealousy(嫉妒). The green eyed monster is not a dangerous animal from outer space. It is an expression used about 400 years ago by the British writer William Shakespeare in his play “Othello”. It describes the unpleasant feeling when someone has something he wants.

In most places in the world, a green light is a signal(信號)to move ahead. In everyday speech, a green light means approval(贊成)to continue with a project.

1.A person with a green thumb____.

A. is good at growing plants B. really has a green thumb

C. has no experience in war D. is new in a job

2.A man may meet the green eyed monster if ____.
