Popular culture often shows alcohol as a big part of the college experience in the United States. Television programs and movies about American college life have images of wild parties with young people either drinking alcohol or holding a drink.

Now, a new study of alcohol use suggests that some college students may be missing meals so they can have more drinks or get drunk faster. Researchers are calling this kind of behavior "drunkorexia".

The study involved 1,184 college students between the ages of 18 and 26. Researchers found that 80 percent of those studied had demonstrated some kind of drunkorexia in the past three months. They had performed heavy physical exercise, eaten low calorie meals or even missed meals for up to a full day before drinking alcohol.

Dipali Rinker organized the study and presented its findings to the Research Society on Alcoholism in June. She says students see drunkorexia as a way to keep their body weight down while drinking alcohol. And it causes them to feel the effects of alcohol quickly and with more intensity（強(qiáng)度）. Rinker says unhealthy eating habits are only one of the reasons why this type of behavior is dangerous. Heavy drinking is linked to drunk driving, unprotected sex, and alcohol poisoning.

George Koob, who directs a U.S. governmental agency that studies alcohol related problems, says that the percent of students using alcohol has not increased in recent years. But what worries him is that the number of students drinking to the point of "blacking out" has increased. Blacking out is when a person drinks so much alcohol they have no memory of their actions while drunk.

Koob notes that college students in Canada and Europe also face issues with alcohol. But he feels a big part of the problem is that Americans do not fully understand alcohol's effects. Most people do not know the part of the brain where decisions are made is not fully developed until age 25 and that alcohol harms the development of that part of the brain, he adds.

1.What is the purpose of the behavior "drunkorexia"?

A. To get drunk. B. To drink more alcohol.

C. To take exercise. D. To lose weight.

2.What can heavy drinking result in?

A. Unhealthy eating habits. B. Drunkorexia.

C. Alcohol poisoning. D. Quick response.

3.Which of the following is the result of blacking out?

A. Missing meals. B. Forgetting something one did.

C. Having unprotected sex. D. Operating a vehicle while drunk.

4.By writing the passage, the writer aims to ________.

A. show heavy drinking and its harm B. show America college life

C. introduce American culture D. explain harmful behaviors

【四川省涼山州高中畢業(yè)班第二次診斷】

B

We’ve reached a strange–some would say unusual–point. While fighting world hunger continues to be the matter of vital importance according to a recent report from the World Health Organization, more people now die from being overweight, or say, from being extremely fat, than from being underweight. It’s the good life that’s more likely to kill us these days.

Worse still, nearly 18 million children under the age of five around the world are estimated to be overweight. What’s going on?

We really don’t have many excuses for our weight problems. The dangers of the problem have been drilled into us by public–health campaigns since 2001 and the message is getting through-up to a point.

In the 1970s, Finland, for example, had the highest rate of heart disease in the world and being overweight was its main cause. Not any more. A public–health campaign has greatly reduced the number of heart disease deaths by 80 percent over the past three decades.

Maybe that explains why the percentage of people in Finland taking diet pills doubled between 2001 and 2005, and doctors even offer surgery of removing fat inside and change the shape of the body. That has become a sort of fashion. No wonder it ranks as the world’s most body –conscious country.

We know what we should be doing to lose weight—but actually doing it is another matter. By far the most popular excuse is not taking enough exercise. More than half of us admit we lack willpower. Others blame good food. They say: it’s just too inviting and it makes them overeat. Still others lay the blame on the Americans, complaining that pounds have piled on thanks to eating too much American–style fast food.

Some also blame their parents—their genes. But unfortunately, the parents are wronged because they’re normal in shape, or rather slim.

It’s a similar story around the world, although people are relatively unlikely to have tried to lose weight. Parents are eager to see their kids shape up. Do as I say—not as I do.

1.What’s the “strange” point mentioned in the first sentence?

A. The good life is a greater risk than the bad life.

B. Starvation is taking more people’s lives in the world.

C. WHO report shows people’s unawareness of food safety.

D. Overweight issue remains unresolved despite WHO’s efforts.

2.Why does the author think that people have no excuse for being overweight?

A. A lot of effective diet pills are available.

B. Body image has nothing to do with good food.

C. They have been made fully aware of its dangers.

D. There are too many overweight people in the world.

3.The example of Finland is used to illustrate _______.

A. the cause of heart disease B. there are too many overweight people in the world

C. the effectiveness of a campaign D. the fashion of body shaping

4.Which would be the best title for the passage?

A. Actions or Excuses B. Overweight or Underweight

C. WHO in a Dilemma D. No Longer Dying of Hunger

【廣東省佛山市高明區(qū)第一中學(xué)2017屆高三上學(xué)期第二次大考】D

Why do some people live to be older than others? You know the standard explanations: keeping a moderate diet, engaging in regular exercise, etc. But what effect does your personality have on your longevity(長(zhǎng)壽)? Do some kinds of personalities lead to longer lives? A new study in the Journal of the American Geriatrics Society looked at this question by examining the personality characteristics of 246 children of people who had lived to be at least 100.

The study shows that those living the longest are more outgoing, more active and less neurotic (神經(jīng)質(zhì)的) than other people. Long-living women are also more likely to be sympathetic and cooperative than women with a normal life span. These findings are in agreement with what you would expect from the evolutionary theory: those who like to make friends and help others can gather enough resources to make it through tough times.

Interestingly, however, other characteristics that you might consider advantageous had no impact on whether study participants were likely to live longer. Those who were more self-disciplined, for instance, were no more likely to live to be very old. Also, being open to new ideas had no relationship to long life, which might explain all those bad-tempered old people who are fixed in their ways.

Whether you can successfully change your personality as an adult is the subject of a longstanding psychological debate. But the new paper suggests that if you want long life, you should strive to be as outgoing as possible.

Unfortunately, another recent study shows that your mother’s personality may also help determine your longevity. That study looked at nearly 28,000 Norwegian mothers and found that those moms who were more anxious, depressed and angry were more likely to feed their kids unhealthy diets. Patterns of childhood eating can be hard to break when we’re adults, which may mean that kids of depressed moms end up dying younger.

Personality isn’t destiny, and everyone knows that individuals can learn to change. But both studies show that long life isn’t just a matter of your physical health but of your mental health.

1.The aim of the study in the Journal of the American Geriatrics Society is ________.

A. to see whether people’s personality affects their life span

B. to find out if one’s lifestyle has any effect on their health

C. to investigate the role of exercise in living a long life

D. to examine all the factors contributing to longevity

2.What does the author imply about outgoing and sympathetic people?

A. They have a good understanding of evolution.

B. They are better at negotiating an agreement.

C. They generally appear more resourceful.

D. They are more likely to get over hardship.

3.What finding of the study might prove somewhat out of our expectation?

A. Easy-going people can also live a relatively long life.

B. Personality characteristics that prove advantageous actually vary with times.

C. Such personality characteristics as self-discipline have no effect on longevity.

D. Readiness to accept new ideas helps one enjoy longevity.

4.What does the recent study of Norwegian mothers show?

A. Children’s personality characteristics are invariably determined by their mothers.

B. People with unhealthy eating habits are likely to die sooner.

C. Mothers’ influence on children may last longer than fathers.

D. Mothers’ negative personality characteristics may affect their children’s life spans.

The private automobile (私家車）has long played an important role in the United States. In fact, it has become a necessary and important part of the American way of life. In 1986, sixty-nine percent of American families owned at least one car, and thirty-eight percent had more than one. By giving workers rapid transportation, the automobile has freed them from having to live near their place of work. This has encouraged the growth of the cities, but it has also led to traffic problems.

For farm families the automobile is very helpful. It has made it possible for them to travel to town very often for business and for pleasure, and also to transport their children to distant schools.

Family life has been affected（影響）in various ways. The car helps to keep families together when it is used for picnics, outings, and other shared experiences. However, when teenage children have the use of the car, their parents can’t keep an eye on them. There is a great danger if the driver has been drinking alcohol or taking drugs, or showing off by speeding or breaking down traffic laws. Mothers of victims（受害者）of such accidents have formed an organization called MADD (Mothers Against Drunk Driving). These women want to prevent further tragedies (悲�。�. They have worked to encourage the government to limit the youngest drinking age. Students have formed a similar organization, SADD (Students Against Drunk Driving) and are spreading the same message among their friends.

For many Americans the automobile is a necessity. But for some, it is also a mark of social position and for young people, a sign of becoming an adult. Altogether, cars mean very much to Americans.

1.Which of the following is NOT mentioned in the text?

A. Cars have encouraged the growth of the cities.

B. Cars can bring families together when they go for picnics.

C. Cars have enabled people to live far from their place of work.

2.What has been done to deal with the problem of drunk driving?

A. Parents have paid more attention to their children.

B. Some organizations have been set up against drunk driving.

C. Mothers have tried to persuade their children not to drink alcohol.

D. University students have asked the government to solve the problem.

3.We can infer from the text that in America.

A. it will be more difficult for people to get new cars
