【题目】Want to stay away from colds? 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 positive(积极的) feelings may reduce (减少) 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 the happy or sad feelings they had that day. After the two weeks, the people were given colds by doctors and had to stay alone in a room for six days.

The result showed that everyone in the study was equally(相等地) likely to get ill. But for people who said they felt happy during the research period, their illness was 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 about your health, look on the bright side more often.

试题分析:本文主要介绍了一项显得研究:相比较不高兴、消极的人而言,积极、高兴、心情舒畅的人更不会患上疾病,例如:感冒。在调查中,人们需要告诉研究者那天他们高兴的心情或者是他们伤心的心情。在两周后,那些被医生患上感冒的人不得不独自待在房间里六天,最后得出结论:我们应该保持好自己的心情以减少疾病。

【1】细节理解题。从文中第五段里“During the interviews, the people told researchers about the happy or sad feelings they had that day.”在调查中,人们需要告诉研究者那天他们高兴的心情或者是他们伤心的心情。可知A正确。“After the two weeks, the people were given colds by doctors and had to stay alone in a room for six days.”在两周后,那些被医生患上感冒的人不得不独自待在房间里六天。可知B、C正确。故选D。

【2】细节理解题。从文中第二段里“It's possible that being happy helps the body fight illnesses.”保持愉快地心情可能帮帮助身体对抗疾病。故选D。

【题目】One day a teacher was giving her young students a lesson on how the government works. She was trying to explain the principle(原理) of income tax(所得税).“You see,” she began, speaking slowly and carefully, “Each person who works must pay part of his or her salary( 薪水) to the government.

All the students nodded.“Are there any questions? ”sheasked. All the students shook their heads.“Very good!”she said. “Now, I would like you to take a piece of paper and write a short composition on the subject of income tax.”

Little Joey was a slow learner. He had lots of problems with spelling and grammar, but this time he at least seemed to understand the task.

【题目】Scientists have discovered a special biological behavior in dolphins(海豚) that could lead to a treatment for late-onset diabetes(晚发的糖尿病) in humans. Studies on dolphins found that healthy dolphins switch into a diabetic-like state overnight when they are not feeding, but return to normal when they eat the following morning.

The extraordinary finding has led scientists to suggest that dolphins have “genetic switch” that allows them to imitate diabetes while they are not feeding for a night, without suffering any ill effect.

If researchers can identify a similar genetic pathway in human, they may be able to develop drugs to effectively switch off diabetes. Some 2.2 million people in Britain have type 2 (or late-onset) diabetes, a figure that is expected to reach 4 million by 2025 as a consequence of rising levels of obesity(肥胖).

The tissues of people with type 2 diabetes have become resistant to insulin(胰岛素)so they lose the ability to control sugar levels in their blood. The condition can damage the heart, eyes, kidneys(肾脏) and nerves and contribute to 5% of all deaths, according to the World Healthy Organization.

Dolphins appear to imitate diabetes to keep high levels of blood sugar when food is rare. Like humans, dolphins need some sugar in their blood for their brains to function normally. Venn-Watson’s team analyzed 1,000 blood samples(样本) from 52 dolphins while they didn’t eat anything overnight and fed in the morning. At night time, the dolphins’ metabolism(新陈代谢)changed greatly and showed similar characteristics to that seen in people with type 2 diabetes.

“It is our hope that this discovery can lead to new ways to prevent, treat and maybe even cure diabetes in humans,” said Stephanie Venn-Watson, director of clinical research at the National Marine Foundation in San Diego.

B. Dolphins can switch into a diabetic-like state overnight.

C. Humans can suffer the same disease as dolphins.

D. Dolphins should be fed regularly to avoid diabetes.

2The key to applying the finding to curing human diabetes lies in ____________.

A. producing insulin in a larger amount

D. analyzing more blood samples from hungry dolphins

3Which of the following statements is TRUE according to the passage?

A. Scientists have found a similar genetic switch in humans.

B. More British people will suffer type 2 diabetes due to obesity.

C. 2.2 million people with type 2 diabetes die in Britain every year.

D. Dolphins imitate diabetes to avoid a high blood sugar level.

4What will happen to dolphins if not fed for a night according to Venn-Watson?

A. Their metabolism breaks down.

B. They become resistant to insulin.

C. Their heart and kidneys are damaged.

D. They keep high levels of blood sugar.
