Ever feel like you’ve been hit on the head after a bad night’s sleep? According to scientists, the thought isn’t as unbelievable as it seems.
A study found going without sleep for just one night causes changes in the brain similar to those that happen after a blow to the head. The researchers said the healthy young men examined in the study showed a sudden rise in the same chemicals which indicate(表明) brain damage. Professor Christian Benedict, of Uppsala University, Sweden, explained that the chemicals NSE and S-100B are biomarkers(生物指标) for brain damage, such as concussion(脑震荡). He said, “What we found was their levels in the blood rose in the group that went without sleep for a night. This was not to the degree that would happen after a head injury, for example, but it was still worth paying attention to. During sleep, the brain cleans itself of poisonous substances.” He said the findings support the previous(以前的) research showing how the brain makes use of sleep to clean itself.
Professor Benedict also said his study could support previous studies which linked a lack of sleep with increased risk of Alzheimer’s and Parkinson’s diseases. The rise of the chemicals in the blood after sleep loss may suggest not getting enough sleep leads to a loss of brain tissue, he explained. Professor Benedict, whose study is published in the journal Sleep, added, “In conclusion, the findings of our trial indicate a good night’s sleep may be very important for keeping brain health.”
A third of the UK population suffer from sleep-related problems, while the average person now sleeps for only seven hours a night, compared with almost nine a few decades ago. Many scientists believe irregular sleeping patterns lead to illnesses ranging from aches and pains to heart disease, while less than eight hours’ sleep a night can lower the IQ the next day.
1.If you don’t sleep for a night, what will happen?
A. There will be a rise in the chemicals NSE and S-100B
B. The chemicals NSE and S-100B will drop to a lower level
C. Some of the chemicals NSE and S-100B will change into other matters
D. The chemicals NSE and S-100B will be less able to get rid of poisonous matters
2.What is the previous study mainly about according to the passage?
A. The way to avoid brain damage
B. The ways to improve the quality of sleep
C. The ways that have effect on people’s sleep
D. The way the brain uses sleep to clean itself

A. man’s intelligence is affected by sleep in a way
B. people who need more sleep have a higher IQ
C. one fourth of the UK population have sleep-related problems
D. modern people need less sleep than those a few decades ago

Ever order a drink, and feel cheated on the pour? Before you trouble the waiter, take a closer look at the size of your glass. “People will generally think there being less in larger containers, than in smaller ones.” Says Theresa Marteau, a behavioral scientist at the University of Cambridge, in England.
She and her workmates had analyzed（分析）how larger amounts—and larger plates—trick us into eating more food. And they wondered: could the same be true for alcohol?
So the researchers convinced the employees at a local bar to run an experiment: every two weeks, for four months, they’d change the bars wine glasses from the standard 300 milliliter size, to either slightly larger—370 milliliters, or slightly smaller—250 milliliters. They saw how the size of the glass affected customers’ drinking habits, even though the pour, the amount of alcoholic drinks, was unchanged.
It turned out that serving wine in smaller glasses had no measurable effect. But the large glasses increased wine sales 10 percent-even after controlling for day of the week, temperature, holidays and so on. The reason? “When the wine, the same amount, is being served in a larger glass, people are probably thinking they’ve got less in there.” Which, she says, means they might drink more, believing they haven’t hit their nightly limit. Or, they might just feel less satisfied with the pour, and buy another round. The study appears in the journal BMC Public Health.
Marteau says that, if later studies confirm this effect, public health officials might consider directing a certain average glass size. “Stating clearly the largest size in which wine can be sold could be a measure to reduce the overconsumption（过度消耗）of alcohol that seems to be shown by the glass size.” Until that happens, the bar in the study now always serves its wine in the larger glasses.
1.How did they do the experiment?
A. By analyzing the pour.
B. By changing the glasses.
C. By controlling the temperature of alcohol.
D. By limiting the quantity of alcohol they served.
2.What did they find through the study?
A. Larger containers persuaded people to drink more.
B. Wine sales increased when they changed the wine glasses.
C. People’s drinking habits were not affected by anything.
D. More customers prefer wine served in larger glasses.
3.What can we learn from the last paragraph?
A. There are limits to glass sizes in bars.
B. Public health officials are trying to reduce the sales of wine.
C. The bar continues to use larger glasses for the study.
D. The study may help to control alcohol overdrinking.
4.What can be a suitable title for the text?
A. What Affects People’s Drinking Habits
B. Drink as Much as Offered
C. The Smaller the Glasses, the Less You Drink
D. Bigger Glasses Encourage More Wine Consumption

Everyone has good days and bad days.
Sometimes, you feel as if you’re on top of the world. But occasionally you feel horrible, and you lose things and you cannot focus on your schoolwork.
For more than 20 years, scientists have suggested that high self-esteem (自尊) is the key to success. Now, new research shows that focusing just on building self-esteem may not be helpful. In some cases, having high self-esteem can bring bad results if it makes you less likeable or more upset when you fail at something.
“Forget about self-esteem,” says Jennifer Crocker, a psychologist (心理学家) at the University of Michigan, US. “It’s not the important thing.”
Feeling good
Crocker’s advice may sound a bit strange because it is good to feel good about yourself.
Studies show that people with high self-esteem are less likely to be depressed, anxious, shy, or lonely than those with low self-esteem.
But, after reviewing about 18,000 studies on self-esteem, Roy Baumeister, a psychologist at Florida State University, has found that building up your self-esteem will not necessarily make you a better person.
He believes that violent and wicked (邪恶的) people often have the highest self-esteem of all. He also said: “There’s no evidence that kids with high self-esteem do better in school.”
Problems
All types of people have problems. People with high self-esteem can have big egos (自我) that can make them less likeable to their peers(同龄人), said Kathleen Vohs, a psychology professor at Columbia University.
People with high self-esteem tend to think more of themselves, Vohs says. People with low self-esteem are more likely to rely on their friends when they need help.
What to do
Researchers say it is best to listen to and support other people. Find positive ways to contribute to society. If you fail at something, try to learn from the experience. “The best therapy (药方) is to recognize your faults,” Vohs says. “It’s OK to say, ‘I’m not so good at that,’ and then move on.”
1.The new research comes to the conclusion that high self-esteem ________.
A. is not important at all
B. may not be the key to success
C. has taken on a different meaning
D. does not help you do better at school
2.One of the conclusions of the new research is that ________.
A. people with high esteem tend to be proud
B. people with high esteem usually do not seek other’s help
C. feeling good about oneself doesn’t mean you lead a happier life
D. people with low esteem are often more popular
3.The underlined part “a better person” in the passage probably means a person who is ______.
A. helpful and supportive B. gentle and modest
C. likable and successful D. friendly and kind
4.From the text, we can infer the best therapy mentioned in the last paragraph is mainly for people ________.
A. of all kinds
B. with low self-esteem
C. with high self-estee
D. who are focusing on building self-esteem

There's a man in the habit of hitting me on the head with an umbrella. At first I couldn't stand it；now I'm used to it.
I don't know his name. I know he's average in appearance，wears a gray suit，and has a common face. One hot morning，when I was sitting on a treeshaded bench in Palermo Park，reading the paper，suddenly I felt something touch my head. It was the very same man who now，as I'm writing，keeps striking me with an umbrella.
On that occasion I turned around filled with anger. He just kept on hitting me. I asked him if he was crazy. He didn't even seem to hear me. Then I threatened to call a policeman. Calmly，cool as a cucumber，he stuck with his task. After a few moments of hesitation，and seeing that he was not about to change his attitude，I stood up and hit him on the nose. The man fell down. But he immediately got back on his feet，obviously with great effort，and without a word again began hitting me on the head with the umbrella. His nose was bleeding and，at that moment，I felt sorry for him. I felt regret for having hit him so hard. After all，the man wasn't exactly hitting me；he was merely tapping me lightly with his umbrella，not causing any pain at all. Of course，those taps were extremely bothersome. As we all know，when a fly lands on your forehead，you don't feel any pain；what you feel is annoyance. Well then，that umbrella was one huge fly that kept landing on my head time after time.
Convinced that I was dealing with a madman，I tried to escape. But the man followed me，wordlessly continuing to hit me. So I began to run(I should point out many people run as fast as I do). He took off after me，trying to land a blow. The man was out of breath so that I thought，if I continued to force him to run at that speed，he would drop dead right then and there.
1.When the man began to strike the author with an umbrella, the author________.
A. became angry B. called the police
C. turned around and escaped D. turned around and fought back
2.The author would most probably agree that the man was ________.

D. there was a fly on the man's head
4. It can be learned from the passage that the man ________.
A. shouted loudly while hitting the author
