People who averaged fewer than seven hours of sleep per night in the weeks before being exposed to the cold virus were nearly three times as likely to get sick as those who averaged eight hours or more, a new study found.
Researchers used frequent telephone interviews to track the sleep habits of more than 150 men and women aged 21 to 55 over the last few weeks. Then they exposed the subjects to the virus, quarantined (检疫隔离) them for five days and kept track of who got sick.
Besides sleeping more, sleeping better also seemed to help the body fight illness: Patients who fared better on a measure known as “sleep efficiency”—the percentage of time in bed that you’re actually sleeping—were also less likely to get sick.
The results held true even after researchers adjusted for elements such as body-mass index, age, sex, smoking and pre-existing antibodies (抗体) to the virus.
The researchers aren’t exactly sure why sleeping better makes you less likely to develop a cold. But they do try to give an answer: “Sleep disturbance influences the regulation of symptom mediators (调节因子) that are released in response to infection.” In plain English, maybe tossing and turning when you’re infected with the cold virus contributes to the symptoms that define a cold.
The researchers were based at Carnegie Mellon, the University of Pittsburgh and the University of Virginia, and the study was funded by the National Institutes of Health. According to the passage, what does the underlined word “subjects” mean in paragraph 2?
| A．areas of knowledge in a school |
| B．people being studied in an experiment |
| C．research topics |
| D．animals being tested |
It is shown in the passage that _______.
| A．the researchers obtain information about the sleep habits by frequent interviews |
| B．the researchers do their research in the National Institutes of Health |
| C．people hope to avoid being infected with a cold by sleeping as much as possible |
| D．sleeping more and better helps regulate the symptom mediators |
What’s the best title of the passage?
| A．The Relationship Between Virus and Cold |
| B．How to Sleep Well |
| C．Good Sleep Helps Fight a Cold |
| D．The More the Sleep, the Better Your Body |
If you see someone drowning, speed is very important. Once you get him out of the water, if he isn't breathing. you have four minutes before his brain is completely destroyed. Support his neck, tilt(倾斜) his head back and press his chin upwards. This stops the tongue blocking the airway in the throat and is sometimes enough to get him breathing again. If that doesn't work, start mouth-to-mouth breathing. Press his nostrils鼻孔) together with your fingers. Open your mouth and take a deep breath. Blow into his lungs until his chest rises. then remove your mouth and watch his chest fall. Repeat twelve times a minute. Keep doing until help arrives.
To bring a child to life. keep your lips around his mouth and nose and gently blow into his mouth. Give the first four breaths as quickly as possible to fill the blood with oxygen, If, in spite of your efforts, he stars turning a blue-grey colour, you can feel no pulse, then pressing is the last chance of saving his life.
With arms straight, rock forwards, pressing down on the lower half of the breastbone. Don't be too hard or you may break a rib.

There are many stereotypes( 定型 ) about the character of people in various parts of the United States. In the Northeast and Midwest, people are said to be closed and private. In the South and West, however, they are often thought of as being more open and hospitable . Ask someone from St. Louis where the nearest sandwich shop is, and he or she will politely give you directions. A New Yorker might eye you at first and after deciding it is safe to talk to you, might give you a rather unexpected explanation. A person from Georgia might be very kind about directing you and even suggest some different places to eat. A Texan just might take you to the place and treat you to lunch.
American stereotypes are abundant. New Englanders are often thought of as being friendly and helpful. Southerners are known for their hospitality and warmth. People from the western part of the United States are often considered very outgoing. These differences in character can be traced to different factors such as climate, living conditions, and historical development.
When travelling from place to place, Americans themselves are often surprised at the differing degrees of friendliness in the United States.

Have you ever heard anyone say “It’s raining cats and dogs”? It means “It’s raining hard!”
But sometimes cats and dogs do drop from the sky! Here’s how it happens.
Not so long ago, a country far away had many large rats. The people there said, “ We need cats!” So cats were sent to them by airplane. But the country had many mountains. It was hard for an airplane to land. So the cats came down by parachute(降落伞). Did the cats like the ride? They didn’t say they didn’t! And today they are still catching rats!
In another country far away, there is snow the year around. People sometimes got lost in it.
“We need big dogs!” the people said, “The dogs could find people lost in the snow. The dogs could help bring them home. Where can we get big dogs?”
A man across the sea had big dogs to sell. “I will send dogs to you,” he said. “ I have some very big ones. They can find people lost in the snow.”
He sent the dogs by airplane.
But the airplane did not land in the snow. The dogs came down by parachute ---- you guessed it !
Did the dogs like the ride? They didn’t say they didn’t! And today they are well and happy.
They find anyone who gets lost in the snow. Then they help him get home. Good dogs!

The young people who talk of the village as being “dead” are talking nothing but nonsense, as in their hearts they must surely know.
No, the village is not dead. There is more life in it now than there ever was. But it seems that “village life” is dead. Gone for ever. It began to decline about a hundred years ago. When many girls left home to go into service in town many miles away, and men also left home in increasing numbers in search of work, and home was where work was. There are still a number of people alive today who can remember what “village life” meant in the early years of the present century. It meant knowing and being known by everybody else in the village. It meant finding your entertainment in the village of within walking distance of it. It meant housewives tied to the home all day and every day. It meant going to bed early to save lamp oil and coal.
Then came the First World War and the Second World War. After each war, new ideas, new attitudes, new trades and occupations were revealed（展现）to villagers. The long-established order of society was no longer taken for granted. Electricity and the motorcar were steadily operating to make “village life” and “town life” almost alike. Now with the highly developed science and technology and high-level social welfare（福利）for all, there is no point whatever in talking any longer about “village life.” It is just life, and a better life.
Finally, if we have any doubts about the future, or about the many changes which we have seen in our lives, we have only to look in at the school playground any mid-morning; or see the children as they walk homeward in little groups. 0bviously these children are better fed, better clothed, better educated, healthier, prettier and happier than any generation of children that ever before walked the village street.

A new enemy is threatening Japanese traditions: leisure（闲暇）. As part of its attempt to increase imports, the government is trying to get people to work less and spend more. The workers are disgusted.
The figures support the western prejudice（偏见） that the Japanese are all work and no play. Trying to force workers away from their desks and machines, the government said last April that the country should cut down from its 2,100 hours average work year to 1,899 hours and a five-day week by 1992. Beginning in February, banks and stock markets will be closed on Saturdays, staff of civil service will be forced out of their offices two Saturdays a month. The government hopes that others will follow that practice.
But some persuasion will be needed. Small companies are very angry about it and they fear competitors may not cut hours. The unions are no happier: they have even advertised in newspapers arguing their case against the foreign pressure that is forcing leisure upon them. They say that shorter hours are a disguised（隐性的） pay cut. The industrialists, who have no objection to the government’s plans, admit that shorter hours will help them cut costs. Younger Japanese who are supposed to be acting against their hard-working parents, show no sign of wanting time off, either. But unlike older workers, they do spend money in their spare time. Not content with watching television, they dance, dress up, sit in cafes, go to pop concerts and generally drive the leisure-industry boom. Now that they know how to consume, maybe the West can teach them to relax and enjoy themselves, too.
68．The purpose of getting the Japanese to have more spare time is that .
A．the government wants to show more concern for the health of the people
B．the government needs to get more goods from abroad
C．the Japanese have been working too hard
D．the Japanese hope to change the western prejudice
69．The group of people who welcome the shorter-hour system in Japan is .
A．the small companies B．the industrialists
C．the unions D．the younger generation
70．The unions think that .
A．the shorter hours they work, the higher pay the can get
B．the more they work, the less leisure they can enjoy
C．the shorter hours they work, the less pay they can have
D．the greater pressure the government is forcing on them, the less happy they can be
71．The best title for this passage can be .
A．Oh no! Not Saturday Again! B．Leisure: the Greatest Threat!
C．Enjoy While You are Young! D．Less Work and More Play!
