Compared to people with bad attitudes，people who are cheerful and relaxed are less likely to suffer from colds，according to a new study.“It’s possible that being upbeat helps the body fight illnesses，” says Sheldon Cohen，the study’s lead researcher from Carnegie Mellon University (CMU) in Pittsburgh.
In a previous（先前的） study，Cohen and his colleagues put coldcausing viruses into the noses of 334 healthy adults. People who tended to be cheerful and lively were least likely to develop sniffles，coughs，and other 
cold symptoms. People who showed positive feelings were also less likely to mention symptoms to their doctors，even when medical tests detected those symptoms.
Those findings were interesting，but they didn’t prove that a person’s attitude affects whether he or she gets sick. Instead，it was still possible that a person’s underlying personality is what matters. Evidence suggests，for instance，that certain people are naturally more likely to be outgoing and optimistic，with high selfesteem and a sense of control over life. This would mean that who we are，not how we feel，ultimately decides our chances of catching colds.
To figure out which mattered more (personality or emotions)，the CMU team interviewed 193 healthy adults. The researchers talked to each person over the phone every evening for 2 weeks. At the end of the interviewing period，people got nose drops that contained either cold or flu viruses. Then，each person stayed in an isolated room for 5 or 6 days. The results showed that everyone in the study was equally likely to get infected. Their symptoms，however，differed depending on the types of emotions that they had reported over the previous 2 weeks. Among those who reported good moods and had been infected with the flu virus，for example,2
8 percent developed coughs and stuffy noses. On the other hand，those symptoms struck 41 percent of people who had been less upbeat.

Across the globe, single parent homes are on the rise. In the US, the 2000 census (人口普查) showed 24.8 million, or nearly 24 percent of the nation’s 105.5 million households, were traditional two-parent homes. By comparison, 9.8 million households, or 9 percent of all US households were headed by an adult raising a child alone. The 1990 census showed 26 percent of homes were led by a married mother and father, and 8 percent of homes were led by a single parent.
Similar increases occurred in other countries. In the UK, lone-parent homes increased from 3.3 percent in 1990 to 5.5 percent in 1999. Single parent households in Australia rose from 5.8 percent in 1990 to 7.6 percent in 1999. Belgium saw the increase from 1.8 percent to 2.7 percent during the same period of time. These countries tend to have greater acceptance of the single parent because there are fewer nearby family members to disapprove, Riche, a Census Bureau director, said.
Just as in the US, those changes raised new questions about how involved govenment should be in helping single parent families. Some research suggests children raised in two-parent families are better off than those who depend on one.
“The position of one-parent families in any country is very much a gender (性别) issue-women’s opportunities, especially working-class women on low income,” said Sue Cohen, coordinator (协调员) of the Single Action Parents Network in England.Not considering the exact number of the single-parent families, which country saw the fastest rise rate in 1999, compared with 1990?
| A．UK. | B．Australia. | C．America. | D．Belgium. |
What is the cause of the rise of single parent families across the globe?
| A．The nearby family members have a favourable opinion. |
| B．A lone parent is well off enough to support his /her children. |
| C．A lot of problems have arisen in two-parent families. |
| D．We cannot get enough proving information from the text. |
Which of the following is TRUE about the increase of single parent families according to the passage?
| A．It will somewhat limit the growing population of younger generation. |
| B．Governments should take actions about the social problems brought about by it. |
| C．Single parent families are not looked down upon in any country mentioned here. |
| D．Generally speaking, the single parents needn’t worry since they are highly paid. |
Which of the following diagrams correctly shows the rise of single parent families in the US from 1990 to 2000?
Does a drink a day keep heart attacks away? Over the past 20 years, numerous studies have found that moderate alcohol consumption, say, one or two beers, glasses of wine or cocktails daily helps to prevent coronary heart disease. Last week a report in the New England Journal of Medicine added strong new evidence in support of that theory. More important, the work provided the first solid induction (归纳) of how alcohol works to protect the heart.
In the study, researchers from Boston’s Brigham and Women’s Hospital and Harvard Medical School compared the drinking habits of 340 men and women who had suffered recent heart attack with those of healthy people of the same age and sex. The scientists found that people who sip one to three drinks a day are about half as likely to suffer heart attacks as nondrinkers are. The apparent source of the protection: those who drank alcohol had higher blood levels of high density lipoproteins, the so-called good cholesterol, which is known to prevent heart disease.
As evidence has mounted, some doctors have begun recommending a daily drink for patients of heart diseases. But most physicians are not ready to recommend a regular happy hour for everyone. The risks of teetotalling (绝对戒酒) are nothing compared with the dangers of too much alcohol, including high blood pressure, strokes and liver troubles—not to mention violent behaviour and traffic accidents. Moreover, some studies suggest that even moderate drinking may increase the incidence of breast and colon cancer. Until there is evidence that the benefits of a daily dose of alcohol outweigh the risks, most people won’t be able to take a doctor’s prescription to the neighbourhood bar or liquor store.The medical article quoted in the first paragraph indicates .
A. the way in which alcohol can help the heart
B. how a couple of cocktails daily can stop heart problems

When we hear the words “college students”, we usually think of a young person between 18 and 22 years old. But in the U.S.A today, a college student often is much older. In fact, educators say in the next few years colleges and universities may have more older part-time students than traditional (传统的) full-time younger students.
Educators report a big increase in the number of Americans who attend college and university classes in the evening or at night or weekends. Most of them are older than 25 years old and more have full-time or part-time jobs. Many are in their thirties or forties.
Why are so many people deciding to spend their time and money in order to continue their education? Most are doing it because they believe more education will help them to get a better job. Some are industrial workers whose factories have closed. They are learning new skills to prepare for other kinds of work. Some of the part-time students are not pleased with the jobs they have. They are studying for new ones. Some have retired (退休) and are looking for new kinds of work. Two of every three of the students older than 35 are women. Many of them are returning to school after years of staying at home to care for children.
Are older students good students? Most teachers say yes. They say older students really want to learn. They ask difficult questions and are not pleased with simple answers. They often get high grades. It’s said that in the next few years _________________.
| A．students in colleges and universities will be much older |
| B． full-time students in colleges and universities will be even younger |

American’s genius with high technology may have put men on the moon, but there is growing doubt about its ability to solve human problems closer to home.
In fact, a slight but significant change from purely technological solutions is already under way as scientists insist that answers to the world’s problems will not come from an attractive exhibition of electronics and machines. Instead, as they see it, solutions must develop from a better understanding of the humans that drive the system and from a fuller appreciation of the limits and potential(潜能) of the earth’s resources.
What this means is an increased emphasis on the life and earth sciences, on sociology, psychology, economics and even philosophy.
More and more of the best minds in science, particularly young researchers, are being drawn into these developing fields.
All this is not to say that technological creativity will not play a critical role in solving energy and food shortages, or that answers to environmental difficulties will not come from further advances in the same technologies that may have helped cause the problems.
Where the real challenge lies, in the view of the new generation of scientists, is in finding ways to produce goods and meet the world’s needs, using less of the raw materials that are becoming short. Which of the following would the author probably agree with?
| A．The environment crisis will not be solved unless we stop using virgin（原始）materials. |
| B．In scientific research, a higher priority（优先）should be given to understanding all living systems. |
| C．Exploration of outer space will finally lead to an improvement on human living conditions. |
| D．U. S. high-technology companies are welcoming this new change in scientific research. |
Which of the following best expresses the main idea?
| A．a growing number of Americans are doubtful about what high technology can do in solving the world’s problems. |
| B．Many scientists are beginning to believe that the better understanding of human beings will play a more decisive role in solving the world’s problems. |
| C．More and more young scientists are trying their best to find new ways to solve the world’s problems. |
| D．Technological creativity will still play a very important part in solving the world’s problems. |
Young scientists demand that in order to satisfy human needs ________.
| A．existing products be improved. |
| B．more complex machines and electronic equipment be designed. |
| C．ways be found to produce better goods using fewer raw materials. |

| D．many scientists argue that high technology is something but not everything. |
My father had returned from his business visit to London when I came in, rather late, to supper. I could tell at once that he and my mother had been discussing something. In that half-playful, half-serious way I knew so well, he said, "How would you like to go to Eton?"
"You bet," I cried quickly catching the joke. Everyone knew it was the most expensive, the most famous of schools. You had to be entered at birth, if not before. Besides, even at 12 or 13, I understood my father. He disliked any form of showing off. He always knew his proper station in life, which was in the middle of the middle class, our house was medium-sized; he had avoided joining Royal Liverpool Golf Club and went to a smaller one instead; though once he had got a second-hand Rolls-Royce at a remarkably low price, he felt embarrassed driving it, and quickly changed it for an Austin 1100.
This could only be his delightful way of telling me that the whole boarding school idea was to be dropped. Alas! I should also have remembered that he had a liking for being different from everyone else, if it did not conflict with his fear of drawing attention to himself.
It seemed that he had happened to be talking to Graham Brown of the London office, a very nice fellow, and Graham had a friend who had just entered his boy at the school, and while he was in that part of the world he thought he might just as well phone them. I remember my eyes stinging(刺痛) and my hands shaking with the confusion of my feelings. There was excitement, at the heart of great sadness.
"Oh, he doesn’t want to go away," said my mother, "You shouldn’t go on like this.” “It’s up to him," said my father. "He can make up his own mind."The house the writer’s family lived in was ________.
| A．the best they could afford | B．right for their social position |

The writer’s father enjoyed being different as long as ________.
| A．it drew attention to him | B．it didn’t bring him in arguments |
