     People have often wondered about Margaret Thatcher's famous claim that she only needed four
hours of sleep a night. People were amazed that former British Prime Minister had managed to run the
country on so little sleep. Most people need at least seven or eight hours rest every night.
     But now scientists have discovered a gene(基因)that affects the amount of sleep we need and which
allows some people to survive on fewer hours. They found a mother and a daughter who have a rare
gene that allows them to sleep less than the rest of their family -but still feel alert during the day. The pair
managed to stay alert on about six hours sleep a night, two hours less than the rest of their family needs.
     The finding, published in Science magazine, offers a new direction for studies on how sleep affects
health. Experts say adults need seven to nine hours of sleep for good health, while teenagers and kids
need more. People who don’t get enough sleep are more likely to get sick and suffer from memory loss.
     In 2001,scientists at the University of California discovered a mutation(突变)in a gene that causes
people with that gene to have very unusual sleeping patterns. These people go to bed around 7:30 pm
and wake around 3:30 am.
     Now the team has found a gene that affects how long a person can stay asleep. In the family they
studied, the 69-year-old mother and her 44-year-old daughter usually went to bed around 10 pm. The
mother woke up around 4 am, and her daughter woke up around 4:30 am. Both of them felt fully rested.
     Blood tests showed the women have a mutation in a gene named DEC2, which regulates the body's
clock.
     Researcher Ying-Hui Fu bred(培育) mice and fruit flies to carry the mutation. The flies and mice with
the mutation slept less than ordinary flies and mice, and needed less time to recover from little sleep.
1. What is the main idea of the passage?
A. Less sleep does not affect people's health.
B. Different people have different sleeping patterns.
C. New measures can reduce the effect of less sleep on health.
D. The hours we need to sleep may be affected by some gene in our body.
2. The underlined word "alert" in Paragraph 4 is similar in meaning to        .
A. comfortable
B. wide awake
C. quite alive
D. sleepy
3. In the study, the mother and the daughter       .
A. were found to have a mutation in the gene DEC2
B. were asked to sleep less than other family members
C. had the same sleeping pattern as other family members
D. suffered from memory loss for sleeping only six hours a night
4. According to the passage, the new finding can help       .

Different people use different languages. We Chinese speak Chinese, and, most of us are learning a foreign language. But there is another kind of language we need to know --- the language of the body.
All over the world, people “talk with their hand, with their heads and with their eyes.” When Japanese people meet, they bow. When Indians meet, they put their hands together. What do American and British do? Americans are more imformal(不拘小节的) than the British. They like to be friendly. They use first names, they ask questions and they talk easily about themselves. When they sit down, they like to relax in their chairs and make themselves comfortable. British people are more reserved(保守的). They take more time to make friends. They like to know you before they ask your name.
When British or American people meet someone for the first time, they shake hands. They do not usually shake hands with people they know well. Women sometimes kiss their women friends, and men kiss women friends (on one cheek only). When a man meets a man, he just smiles, and says, “Hello.” Men do not kiss each other, or hold hands. Even fathers and sons do not often kiss each other.
