Internet use appears to cause a drop in psychological health, according to a research at Carnegie Mellon University.
Even people who spent just a few hours a week on the Internet experienced more depression(沮丧) and loneliness than those who used Internet less frequently, the two-year study showed. And it wasn’t that people who were already feeling bad spent more time on the Internet, but that using the Net actually appeared to cause the bad feeling.
Researchers are puzzled by the results, which were completely the opposite to their experiences. They expected that the Net would prove socially healthier than television, since the Net allows users to choose the information and to communicate with others.
The fact that Internet use reduces time available for family and friends may explain the drop in well-being, researchers supposed. Faceless, bodiless “virtual” communication may be less psychologically satisfying than actual conversation, and the relationships formed through it may be shallower. Another possibility is that knowing the wider world via the Net makes users less satisfied with their lives.
“But it’s important to remember this is not about the technology; it’s about how it is used,” says psychologist Christine Riley of Intel, one of the study founders. “It really points to the need for considering social factors in terms of how you design applications(应用) and services for technology.”
小题1:The best title of the passage probably is        .
A.Internet May Cause Depression
B.The Danger of Internet
C.Communication with Others by Internet
D.Puzzled by the Results
小题2:Why did the results of research puzzle the researchers?
A.People could choose their information through Internet.
B.They had expected the opposite results.
C.People can communicate with others.
D.They had thought Internet was much healthier.
小题3:Which of the following may be the cause of depression?
A.Net users found their living conditions bad.
B.Net users already had mental problems.
C.Deep relationships were formed through Internet.
D.Net users had less time to communicate with other people.
小题4:The writer’s attitude towards technology is        .
A.social factors must be considered while using technology
B.technology was to blame for depression
C.the problem doesn’t lie in technology
D.applications and services for technology must be designed

相关题目
Below is a selection from a popular science book.
If blood is red, why are veins(静脉) blue?
Actually, veins are not blue at all. They are more of a clear, yellowish color. Although blood looks red when it’s outside the body, when it’s sitting in the vein near the surface of the skin, it’s more of a dark reddish purple color. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison.
Which works harder, you heart or your brain?
That kind of depends on whether you’re busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker. But in the long run, your brain probably tips it, because even when you’re sitting still your brain is using twice as much energy as your heart, and it takes four to five times as much blood to feed it.
Why do teeth fall out, and why don’t they grow back in grown-ups?
Baby (or “milk”) teeth do not last long; they fall out to make bigger room for bigger, stronger adult teeth later on. Adult teeth fall our when they become damaged, decayed and infected by bacteria. Once this second set of teeth has grown in, you’re done. When they’re gone, they are gone. This is because nature figures you’re set for life, and what controls regrowth of your teeth switches off.
Do old people shrink as they age?
Yes and no. Many people do get shorter as they age. But, when they do, it isn’t because they’re shrinking all over. They lose height as their spine(脊柱) becomes shorter and more curved due to disuse and the effect of gravity(重力). Many (but not all) men and women do lose height as they get older. Men lose and average of 3-4 cm in height as they age, while women may lose 5 cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again? No, because old people don’t really shrink! It is not that they are growing backwards ----- their legs, arms and backbones getting shorter. When they do get shorter, it’s because the spine has shortened a little. Or, more often, become more bent and curved.
Why does spinning make you dizzy(眩晕的)?
Because your brain gets confused between what you’re seeing and what you’re feeling. The brain senses that you’re spinning using special gravity-and-motion-sensing organs in your inner ear, which work together with your eyes to keep your vision balance stable. But when you suddenly stop spinning the system goes out of control, and your brain thinks you’removing while you’re not.
Where do feelings and emotions come from?
Mostly from an ancient part of the brain called the limbic system. All mammals have this brain area ----- from mice to dogs, cats, and humans. So all mammals feel basic emotions like fear, pain and pleasure. But since human feelings also involve other, newer bits of the brain, we feel more complex emotions than any other animal on this planet.
If exercise wears you out, how can it be good for you?
Because our bodies adapt to everything we do to them. And as far as your body is concerned, it’s “use it, or lose it”! It’s not that exercise makes you healthy, it’s more that a lack of exercise leaves your body weak and easily affected by disease

Ann Whimey, a sophomore(大学二年级学生) at Colorado State University, first had a problem taking tests when she began college. "I was always well prepared for my tests. Sometimes I studied for weeks before a test. Yet I would go to take the test, only to find I could not answer the questions correctly. I would blank out because of nervousness and fear. I couldn't think of the answer."
The young student was experiencing something called test anxiety. Because a student worries and is uneasy about a test, his or her mind does not work as well as it usually does. The student cannot write or think clearly because of the great nervousness. though poor scores are often a result of poor study habits, sometimes test anxiety causes low scores. Recently, test anxiety has been recognized as a real problem, not just an excuse or a false explanation of lazy students.
Special university counseling(咨询) courses try to help students. In these courses, counselors try to help students by teaching them how to manage test anxiety. At some universities, students take tests to measure their anxiety. If the test shows their anxiety is high, the students can take courses to help them deal with their nervousness. These courses teach students how to relax their bodies. By controlling their nervousness, they can let their minds work at ease, learn information, then come out without difficulty in a test.
An expert at the University of California explains, "With almost all students, relaxation is felt after taking our program. Most of them have better control during their test. Almost all have some improvements. For some, the improvement is very great.

小题3:In order to get rid of test anxiety, students should  
A.take tests to measure their anxiety
B.take counseling courses to help themselves
C.let their minds work at ease

We have proof that you become what you eat. When you know the effects of different types of food, you can use your knowledge well and eat what you want to become.
Food has an impact on our physical and mental health. Have you ever heard any of the following advice?
Lettuce (莴苣) or milk can make you sleepy.
To stop feeling sleepy you should eat peanuts or dried fish.
Everyone has their own advice to give, which they have read about or have been told by older relatives. Some of these pieces of advice seem to contradict each other.
Eating chocolate makes you fat and gives you spots.
Chocolate contains the essential minerals: iron and magnesium (镁).
What we need to figure out is what type of chocolate to eat to get the benefits and how much of it to eat. We can do this by reading the list of ingredients (原料) on the chocolate bar package. Exactly how much real chocolate is in there? And how much of that do we need to eat to get the benefits of the minerals it contains?
Future restaurants might be named after the physical or mental state they hope to create. Their menus will list the benefits of each dish and drink. Some restaurants have already started this concept, and list the nutritional (营养的) content of their dishes on the menus.
Let’s take the restaurant “Winners” as an example. Their menu would list dishes specifically designed to help you win sports competitions. Or you could choose the Go-faster salad, which is a large bowl of mixed raw vegetables in a light salad dressing, giving you energy without making you gain weight. And what kind of dishes do you think would be on the menu at the “Clever Café”?
So what’s going to happen to hamburgers and biscuits? Will the concept of eating food, because it’s tasty, go out of fashion? Of course not! Junk food is also changing. If ice-cream is not good for children, can’t we give them fat-free, sugar-free tofu ice-cream? Unhealthy food is going out of fashion, so brands are changing. We are told not to drink cola because of the sugar and caffeine content so cola companies are making sugar-free and caffeine-free drinks. We are told dried fruit is a healthier snack than biscuits so some biscuit companies are making biscuits with added vitamins.
小题1:By saying “you become what you eat”, the writer means that ________.
A.you will become your own food
B.you will know what food is good by its appearance
C.food has an effect on your health
D.you will know the effects of different types of food
小题2:What does the underlined word “contradict” mean in the text?
A.Oppose toB.Help with
C.Have influence onD.Benefit from
小题3:How can we eat chocolate properly, according to the passage?
A.To eat chocolate containing the essential minerals.
B.To read the list of ingredients on the package.
C.To get advice from others before eating real chocolate.
D.To learn how much chocolate we can consume before eating.
小题4:Which is true about the future restaurants?
A.The food in “Winners” can ensure you to win sports competitions.
B.They might list the nutritional content of their dishes on the menus.
C.Hamburgers will disappear in these restaurants.
D.The Go-faster salad helps you go faster.
小题5:The concept of eating tasty food will not go out of fashion because ________.
A.the junk food companies are changing their brand names
B.biscuit companies are making dried fruit
C.junk food will become healthier than before
D.Cola companies are still making cola

Teenagers who do not get enough of the nutrients commonly found in fruits and fish are easier to have bad lungs, coughing and wheezing (喘息).Teens who eat the least of fruit and especially vitamin C have weaker lungs compared to the others.
Teens who take in less vitamin E, found in vegetable oil and nuts, are more likely to have asthma(哮喘), Jane Bums at the Harvard School of Public Health found.
Based on these findings.Bums said that current recommended dose(一剂)of vitamin C, 85 mg a day, may not be enough for teens to have healthy lungs.Teens who eat less fruit and don't take in enough fatty acids (脂肪酸) are more likely to have asthma and the signs of breathing difficulty.
Proper amounts of fatty acids are protective, Bums said, though fish, the best source of fatty acids, is particularly unpopular with teenagers.Fatty acids are also found in some nuts as well as some green vegetables'.Smokers who avoid vitamin C will increase their chances of coughing, wheezing and developing phlegm(痰).
More than 80 percent of teens are getting their recommended doses of vitamin C - mainly from fruit drinks."I wouldn't approve of drinking them, but at least they're getting their vitamin C from somewhere," Burns said.
Burns added that there are several different ways to get the necessary nutrients."I think vitamin supplements are fine.I think adding vitamin D to orange juice is fine.But I do think there are added benefits that we don't fully understand of eating whole foods like fruits and vegetables and fish," she said.The researchers did not account for poverty and other factors that often distinguish less-healthy eaters and may explain their findings.
小题1:According to the passage, what is the problem with teens who don't get enough nutrients?
A.They are becoming smokers.B.They don't take enough exercise.
C.They eat too much fruit and fish.D.They are likely to have weaker lungs.
小题2:According to Burns, how should teens get the necessary nutrients?
A.By drinking juice as much as possible.
B.By eating more whole foods.
C.By taking vitamin pills.
D.By giving up smoking.
小题3:Which of the following is NOT mentioned by the researchers in the passage?
A.The amount of nutrients teens should take in a day.
B.How teens can take in enough nutrients.
C.Whether poor teens can prove their findings.
D.The fact that teens don't like fish.
小题4:What is the best title for the passage?
A.Poor nutrition hurts teens' health.B.Teens lack proper nutrition.
C.Teens are easy to suffer from diseases.D.More fruit help keep teens healthy.

Is there anything more important than health? I don’t think so. “Health is the greatest wealth(财富),” wise people say. You can’t be good at your studies or work well when you are ill.       
Speaking about health, I can’t help telling you a funny story.  
An old gentleman came to see the doctor. The man was very ill. He told the doctor about his weakness, memory loss and serious problems with his heart and lungs. The doctor examined him and said there was no medicine for his disease.    
He told his patient to go to a quiet place for a month and have a good rest. He also advised him to eat a lot of meat, drink two glasses of red wine every day and take long walks. In other words, the doctor advised him to follow the rule: “Eat at pleasure, drink with measure and enjoy life as it is.” The doctor also said that if the man wanted to be well again, he shouldn’t smoke more than one cigarette a day.  
A month later the gentleman came into the doctor’s office. He looked cheerful and happy. He thanked the doctor and said that he had never felt a healthier man.  
“But you know, doctor,” he said, “it’s not easy to begin smoking at my age.”
小题1:The writer thinks that     .
