Put on a happy face.Compared to unhappy people, those who are cheerful and relaxed are less likely to suffer from colds, according to a new study. It's possible that being happy helps the body fight illnesses, say the researchers from New York University."It seems that positiv e feelings may reduce the danger of illness," said the study's chief researcher Sheldon Cohen.In an earlier study, Cohen found that people who were cheerful and lively caught coughs and colds less often. People who showed feelings were also less likely to tell their doctors that they felt ill.In this study, Cohen's interviewed 193 adults every day for two weeks. During the interviews, the people told researchers about were given colds by doctors and had to stay alone in a room for six days.The results showed that everyone in the study was equally likely to get ill. Buy for people who said they felt happy during the research period, their illness are less serious and lasted for a shorter time.Cohen believes that when people experience positive feelings, their body may produce a chemical that helps fight illness and disease. So if you are worried abut your health, look on the bright side more often.1. Which of the following was NOT a part of the study?A. People talked about their feelings every day.B.

The danger of coldsD. How people get sickSitting on a chair all day in school can make anyone want to move around. So, more and more teachers are letting students have a ball. By sitting on exercise balls instead of chairs, teachers find students' posture (姿势)and attention improve.Dottie Pownall, a fifth-grade teacher in West Virginia, USA, has been using balls as chairs since December 2008. "The students love them", she says. Pownall took a survey of her students. She found that 80% of the students thought sitting on the balls helped them pay more attention to what they were learning.The teacher, Pisa Witt, felt so strongly about the use of balls as chairs, she started Witt Fitt. This company encourages the use of the balls. And the company educates notonly teachers but also students on how to use them. "Our products are used in 24 states, three provinces in Canada, Puerto Rico ('波多黎各) and Japan," says Witt. "Research shows that sitting on the balls makes them sit up straighter. Y ou can slouch (低头垂肩地坐) on a ball," says Witt, "but it feels awful." Because the students are moving, their blood (血液) increases. That carries more oxygen (氧气to the brain (大脑), so the kids have more energy and can focus longer."Furthermore, they're fun." says Pownali.6. What will happen if a student sits on a chair all day in school? The student will _________.A. pay more attention to his lessonsB. be funC. like to move aroundD. sit up straighter7. How long has Dottie Pownall used the balls?A. About three years.B. Only one year.C. In 2008.D. Since he was a fifth-grade teacher.8. In how many countries are the balls used as the students' chairs?A. Four.B. Three.C. Two.D. One.9. Teachers choose balls instead of chairs because sitting on balls helps the kids___________.A. improve the students' posture and attentionB. slouch on the chairsC. have funD. Both A and C are correct answers.10. Which is better for kids to study in class, sitting on a chair or sitting on a ball?A. Sitting on a chair.B. Sitting on a ball.C. They are the same.D. We don't know.Once upon a time, a young man was standing in the middle of the town announcing that he had the most beautiful heart in the world. A large crowd gathered, and they all praised his heart for it was perfect.Suddenly, an old man appeared and said, ―Why, your heart is not as beautiful as mine.‖The old man’s heart was full of scars(伤疤). Some pieces of his heart were removed and some pieces from other people were put in, but they didn’t fit quite right. So there were several jagged(锯齿状的)edges. In fact, there were still some holes in his heart where the pieces were missing.The young man laughed, ―Comparing yours with mine, mine is perfect and yours is a mess.‖―Y es,‖ said the old man. ―But, every scar shows that I took out a piece of my heart and gave it to a person, and often he gave m e a piece of his heart in return.‖―Why do you have some jagged edges in your heart?‖ asked the young man.―Because the shapes of the pieces weren’t the same.‖ ―Then the holes?‖ ―Sometimes I gave pieces of my heart away, and the other person hasn’t giv en back a piece of his, so …but I don’t care.‖ ―How come?‖ ―They remind me of the love we shared.‖The young man was deeply moved. He walked up to the old man, took a piece of his heart out and gave it to the old man.The old man placed it in his heart, then took a piece from his old scarred heart and placed it in the wound(伤口)in the young man’s heart. It fitted, but not perfectly, as there were some jagged edges.The young man looked at his heart, not perfect any more but more beautiful than ever.How sad it must be to go through life with a whole untouched heart!11.
