There are new findings that not enough sleep may cause people to gain weight. Researchers say a lack of sleep can produce hormonal(激素的) changes that increase feelings of hunger.
In one study, researchers in the United States examined information on more than 1000 people. The people had taken part in a long-term study of sleep disorders.
Some people slept less than five hours a night. They had 15 percent higher blood levels of a hormone called ghrelin than people who slept eight hours. And they had 15 percent less of the hormone leptin. Experts say ghrelin helps make people feel hungry; leptin makes you feel full.
The scientists say these hormonal changes may be a cause of obesity in Western societies. They note the combination that sleep limitation is common and food is widely available.
The results were not affected by how much people exercised. People who are awake longer have more time to burn energy. But the researchers say loss of sleep may increase hunger especially for high-calorie foods, so people gain weight. It seems that, for survival, the body may be designed to store more fat during times with less sleep.
Researchers from Stanford University in California and the University of Wisconsin did the study. They found that the best amount of sleep for weight control is 7.7 hours a night.
The Public Library of Science published the findings in its journal Medicine . Internet users can read the full study, free of charge, at plos. org.Not enough sleep can cause obesity by ______.

Many Chinese students who have learnt English for more than ten years are still unable to speak English very well when they meet a foreigner. They seem to have mastered the basic language structure, but a conversation in English will make them feel uneasy. They are afraid that other people might find out their mistakes.
It's unusual that many students who are bad speakers of English can write English perfectly. This proves that they are unable to organize their idea in English. The center of the problem is that they lack practice and confidence.

Most people seem to be passive at work. They do what they are told to do, and they don’t do what they are not told to do. In the end, one thing results: unmotivated (不积极的) people.
We’re employed to think. In fact, no matter how many times our bosses disagree with us, it is our responsibility to think for the company. There are lots of times when I disagree with my boss, and sometimes we even end up having arguments; however, I still offer my suggestions whenever I don’t agree.
Spending more time thinking also helps us to be more efficient (高效的) and helps to reduce our chances of frustration (挫败). Before I do something, I usually need some time to think about it to make sure that what I’m doing makes sense. This can be as long as a few days when a project is big, or as short as only a few seconds for a simple task. After thinking about a project, it sometimes becomes clear that a simple task could achieve the same result. In those cases, not only did I save myself from possible frustration, but I also felt happy and satisfied that I saved valuable resources for my company.
With so many people not taking time to think, it’s no wonder that many people are unmotivated. Today, I encourage you to think things over whenever you have a chance. At first, it might take a while, but once it becomes a habit, you will feel more motivated as you will be more valuable to the company.

Our eating habits are very important for good health and a strong body. There are times when most of us would rather eat sweets and ice-cream than meat and rice. Sweets and ice-cream are not bad if we eat them at the end of a meal. If we eat them before a meal, they may take away our appetite (食欲). It is important for us to eat our meals at the same time each day. When we feel hungry, it is a sign that our body needs food. When we feel angry or excited, we may not want to eat. A long time ago, in England, some judges used to decide whether a man was telling the truth by giving him some dry bread. If the man could not eat the bread, it showed that he was telling lies. Although this seems very strange and rather foolish, it is indeed a very good way of finding out the fact. A man who is worrying about something has difficulty in eating anything dry. Because he is worrying, he loses his appetite and does not want to eat.

A new study has claimed that men really are more intelligent than women . The study concluded that men’s IQs are almost four points higher than women’s.
British-born researcher John Philippe Rushton says the finding could explain why so few women make it to the top in the workplace.
The Oxford University reached his conclusion after Scrutinizing the results of university ability tests taken by 100,000 students aged 17 and 18 of both sexes.
A focus on the factors such as the ability to quickly grasp a complex concept , verbal reasoning skills(语言推理能力) and creativity—some of the key factors of intelligence ---showed the male teenagers had IQs that were an average of 3.63 points higher. The average person has an IQ around 100 . The findings , which held true for all classes and levels of education , overturn 100-year opinion that men and women average the same in general mental ability. They also conflict(冲突) with evidence that girls do better in school exams than boys.
But Professor Rushton argues that the faster maturing(成熟) of girls leads to them outshining boys in the classroom .

A. a study that shows men are clever than women B. the “glass ceiling “phenomenon

A. a little less than 100 B. 100 C. more than 100 D. 96.37
50. Which of the following opinions does Professor Rushton NOT accept?
