Having a husband means an extra seven hours of housework each week for women, according to a new study. For men, getting married saves an hour of housework a week. “It’s a well-known pattern,” said lead researcher Frank Stafford at University of Michigan’s Institute for Social Research. “Men usually work more outside the home, while women take on more of the housework.”

　　He points out that differences among households(家庭)exist. But in general, marriage means more housework for women and less for men. “And the situation gets worse for women when they have children,” Stafford said.

　　Overall, times are changing in the American home. In 1976, women busied themselves with 26 weekly hours of sweeping-and-dusting work, compared with 17 hours in 2005. Men are taking on more housework, more than doubling their housework hours from six in 1976 to 13 in 2005.

　　Single women in their 20s and 30s did the least housework, about 12 weekly hours, while married women in their 60s and 70s did the most-about 21 hours a week.

　　Men showed a somewhat different pattern, with older men picking up the broom more often than younger men. Single men worked the hardest around the house, more than that of all other age groups of married men.

　　Having children increases housework even further. With more than three children, for example, wives took on more of the extra work, clocking about 28 hours a week compared with husbands’10 hours.

During the 19th century, scientists found that when certain parts of the brain of a person were hurt, he would lose the power of doing certain things. And so people thought that each part of the brain does a different job. But modern research has discovered that this is not so, for it is not easy to show exactly what each part of the brain does.

In the past fifty years there has been a great increase in the amount or research done on the brain. Scientists have found out that the way the brain works is not so simple as people in general may think. Chemists tell us that about 100,000 chemical changes take place in the brain every second. Some recent researches also suggest that we can remember everything that happened to us. We may not be able to think of the things we have heard and seen but it is kept there in the store-house of the human mind. Earlier scientists thought that the power of one’s brain got weaker and weaker as one grows older. But it is plenty of exercise, it keeps its power. It is now thought that is not true. As long as the brain is given plenty of exercise, it keeps its power. It has proved that an old person who has always been active in the mind has a quicker mind than a young person who has done physical work without using much of his brain.

If you exhibit positive characteristics such as honesty and helpfulness, the chances are that you will be thought as a good-looking person, for a new study has found that the perception （认知） of physical attractiveness is influenced by a person's personality．

The study, which was led by Gary W．Lewandowski, has found that people who exhibit negative characteristics, such as unfairness and rudeness, appear to be less physically attractive to observers．In the study, the participants viewed photographs of opposite-sex individuals and rated them for attractiveness before and after being provided with information about their personalities．

After personality information was received, participants also rated the probability of each individual' s becoming a friend and a dating partner．Information on personality was found to significantly change the probability, showing that cognitive （认知的） processes modify （修改） judgments of attractiveness．

"Thinking a person as having a desirable personality makes the person more suitable in general as a close relationship partner of any kind," said Lewandowski．

The findings show that a positive personality leads to greater expectation of becoming friends, which leads to greater expectation of becoming romantic partners and, finally, to being viewed as more physically attractive．The findings remained consistent regardless of how "attractive" the individual was formerly thought to be or of the participants' current relationship status．

"This research provides a positive outcome by reminding people that personality goes a long way toward determining your attractiveness; it can even change people's impressions of how good-looking you are," said Lewandowski．

1.In the study the participants were required to _____．

A．try to make friends with each other

B．try to prove positive characters make people more attractive

C．exhibit negative characters such as unfairness and rudeness

Are you sometimes a little tired and sleepy in the early afternoon? Many people feel this way after lunch. They may think that eating lunch is the cause of the sleepiness. Or, in summer, they may think it is the heat. However, the real reason lies inside their bodies. At that time – about eight hours after you wake up – your body temperature goes down. This is what makes you slow down and feel sleepy. Scientists have tested sleep habits in experiments where there was no night or day. The people in these experiments almost always followed a similar sleeping pattern (模式). They slept for one long period and then for one short period about eight hours later.

In many parts of the world, people take naps(小睡) in the middle of the day. This is especially true in warmer climates, where the heat makes work difficult in the early afternoon. Researchers are now saying that naps are good for everyone in any climate. A daily nap gives one a more rested body and mind and therefore is good for health in general. In countries where naps are traditional, people often suffer less from problems such as heart disease.

Many working people, unfortunately, have no time to take naps. Though doctors may advise taking naps, employers do not allow it! If you do have the chance, however, here are a few tips about making the most of your nap. Remember that the best time to take a nap is about eight hours after you get up. A short sleep too late in the day may only make you feel more tired and sleepy afterward. This can also happen if you sleep for too long. If you do not have enough time, try a short nap – even ten minutes of sleep can be helpful.

1.Why do people feel sleepy in the early afternoon according to the text?

A. They eat too much for lunch.

B. They sleep too little at night.

C. Their body temperature becomes lower.

A. About 12:30 pm. B. About 1:30 pm.
