Once again, science supports what your grandmother told you: A good night's sleep helps your body fight a cold.
People who averaged fewer than seven hours of sleep per   1  in the weeks before being exposed to the cold virus were nearly three times   2  likely to get sick as those who   3  eight hours or more, a new study found.
Researchers used frequent telephone   4  to track the sleep   5  of more than 150 men and women aged 21 to 55 over the course of a few weeks. Then they   6  the subjects to the virus, quarantined them for five days and kept   7  of who got sick.
  8  sleeping more, sleeping better also seemed to   9  the body fight illness: Patients who fared better on a measure   10  as 'sleep efficiency' - the percentage of time in bed that you're actually sleeping - were also   11  likely to get sick.
The results held   12  even after researchers   13  for variables such as body-mass index, age, sex, smoking and pre-existing antibodies to the   14   .
  15  your grandmother, the researchers aren't exactly sure   16  sleeping better makes you less likely to   17  a cold. But they   18   take a stab at the answer: 'Sleep disturbance influences the regulation of proinflammatory cytokines(促炎细胞因子), histamines, and other symptom mediators that are released in response to infection.'

Moreover, it seems that people are spending more and more time watching some sort of visual entertainment, whether it is television, a video tape or a DVD. Therefore, the effects of visual media cannot be ignored.

Winter depression (or winter blues) is a common affliction (折磨) for those who live in our northern climate. Its clinical name is seasonal affective disorder (or SAD) and up to 5% of the population (especially in northern states) may suffer from it. Seasonal affective disorder is characterized by feelings of sadness and depression that occur in the winter months when the temperatures drop and the days grow short . The depression is often associated with excessive eating or sleeping and weight gain. Women are twice to three times more likely to suffer from the winter blues than men.
There are many effective treatments for winter depression, some of which you can do to help yourself. Increasing your daily exposure to as much natural light as possible can be helpful to many. Any time that you have the opportunity to gain access to more sunlight in the winter months, you should try to do so. Taking walks throughout the day (even if you don’t normally do so), sitting next to a south-facing window at your office, in a classroom, or at home will increase your sunlight exposure. Exercising next to a window or outdoors (when possible) is another activity that can help.
Although it may be difficult to do, maintaining your schedule and lifestyle will help to keep the depression at bay. A regular pattern of sleep is the most important thing to maintain. It may be helpful, for instance, to have your bedroom lights on a timer to turn on a half-hour before you wake. This may help in waking at a regular time every morning, when it is still dark outside in the winter months.
Light therapy has shown to be an effective treatment for seasonal affective disorder. While you can purchase expensive, specialized light therapy lighting fixtures for your home or office, some inexpensive alternatives are also available. Another lighting technique to try is to replace commonly used light bulbs in your home with brighter full spectrum (also known as broad spectrum) light bulbs. While more expensive than regular light bulbs, these bulbs provide light that is similar to natural sunlight.
If none of these techniques seem to help your depressive symptoms, you should consider consulting your family physician or a mental health professional. The winter blues are a form of depression and can be readily treated w ith medications or psychotherapy when other self-help methods aren’t effective. Don’t be afraid to talk about this condition with a professional; it’s nothing to be ashamed or afraid of. With a little effort, the winter blues can be beaten

I came to live here where I am now between Wounded Knee Greek and Grass Greek。Others came too, and we made these little grey houses of logs that you see, and they are square. It is a bad way to live, for there can be no power in a square.
You have noticed that everything an Indian does is in a circle, and that is because the Power of the World always works in circles, and everything tries to be round. In the old days when we were strong and happy people, all our power came to us from the respectful circle of the nation, and so long as the circle was unbroken, the people were getting rich. The flowering tree was the living center of the circle, and the circle of the four quarters nursed it. The east gave peace and light, the south gave warmth, the west gave rain, and the north with its cold and strong wind gave strength and continuous power.
This knowledge came to us from the outer world with our brief. Everything the Power of the World does is done in a circle. The sky is round, and I have heard that the earth is round like a ball, and so are all the stars. Birds make their nests in circle, for theirs are the same as ours. The sun comes forth and goes down again in a circle. The moon does the same, and both are round. Even the seasons form a great circle in their changing, and always come back again to where they were. The life of a man is a circle from childhood to childhood, and so it is in everything where power moves.
Our places were like the nests of birds, and these were always set in a circle, the nation’s circle, a nest of many nests, where the Great Spirit meant for us to nurse our children.
But the “white people” have put us in these square boxes. Our power is gone and we are dying, for the power is not in us any more. You can look at our boys and see how it is with us. Where we were living by the power of the circle in the way we should, boys were men at twelve or thirteen years of age. But now it takes them very much longer to grow up.
小题1:According to the passage, the Indians _______.
A.don’t have modern instruments in their homes
B.refused to move from round places
C.lived in round places, but were forced to live in square houses
D.lived in round places, but then decided to move into square houses
小题2:Two things being compared in the passage are _______.
A.the Indians’ past and present living conditions
B.the Indians’ past and modern beliefs
C.the Indians’ old and new power
D.people and nature
小题3:In the second paragraph “the four quarters” refers to _______.
A.the four rooms of the Indian’s house
B.the four kinds of natural power
C.the four seasons
D.the four directions
小题4:According to the author, once the Indians moved into square houses, _______.
A.they had to move to other houses
B.boys took more time to grow into men
C.they forgot the old way of life
D.everyone was not happy
Interpersonal Distance
With the outbreak of SARS,everyone tried to avoid coming into close contact with each other.In those days,interpersonal distance increased,“close contact” almost became synonymous with “danger”,and even children couldn’t have close contact with their mothers.Now SARS has disappeared,and we return back to normal living again.Then,how can we do handle interpersonal distance in our everyday lives?
Studies show that interpersonal distance can be divided into 4 different types:intimate distance,personal distance,social distance,and public distance.
Intimate distance is the interpersonal distance of a person with the people closest to him or her.It ranges from 0 to 45 cm.When a stranger comes within this distance,a person will have strong negative reaction.In crowded buses,strangers usually maintain rigid poses and try to avoid body contact,but couples,lovers,children and their mothers usually lean close to each other.Intimates who aren’t able to live close together for a long time can become alienated.Also,touching is also very important.A contrast test shows that the nervous systems of babies who are often caressed by their mothers develop much faster and their weight increases faster,by 47%,than that of other babies.
Personal distance ranges from 45 cm to 1 m.People can converse genially at this distance without invading each other’s personal space.When friends and acquaintances meet on the street,they usually greet and converse at this distance.
Social distance generally ranges from 1 m to 3 m.Among this range,1-2 m is usually the distance in which people deal with private affairs in social activities.For example,when you get money from banks,in order to protect your privacy,other customers are required to stand at least 1 m away from you.2-3.5 m is a farther social distance.Business talks usually occur at this distance.Besides talking,proper eye contact is also indispensable.Otherwise,each side will feel disrespected.
Public distance is usually used in public gatherings.It generally ranges from 3.5 m to about 7 m.Beyond this range,people can’t communicate using a normal voice.In classrooms,experienced teachers usually leave their lecture platforms to enhance their teaching.
Under different cultural contexts,the interpersonal distance differs slightly,but its basic laws are the same.When conversing,people in love lean very close to each other,acquaintances lean closer than strangers,females lean closer than males,and extraverts lean closer than introverts.In life,harmonious interpersonal relationships are set upon proper interpersonal distances,and some conflicts start from improper interpersonal distances.
小题1:According to the text,the strangers standing close to each other in a crowded bus may_________.
A.try to keep a distance awayB.feel uneasy
C.feel nervousD.be rude to each other
小题2:The distance between a teacher and students in class belongs to _________.

C.their charactersD.their cultural background
小题4:To keep proper interpersonal distance is important because _________.

Wine drinkers tend to buy healthier food than beer drinkers, according to a Danish study published on Tuesday on the website of a weekly medical magazine.
People who bought wine at the store were also more likely to buy fruit, vegetables, fish, lean meat (瘦肉) and milk than beer buyers did, said the study.
Beer buyers were more likely to buy frozen dinners, cold cuts, pork, sugary products, and soft drinks.
The study was conducted by four researchers from the National Institute of Public Health over the course of six months.
Alcohol researchers Erik Schulenburg and Marten Greenback and two other doctors collected 3.5 million receipts from 98 stores. The customers at the stores represented a large number of Danish people, they said.
“Our results confirm international studies which show that wine drinkers tend to eat more fruit, vegetables and fish and rarely eat fats, compared to those who like other kinds of alcoholic drinks,” they concluded.
Wine buyers also tended to have higher education levels, higher earnings and be in better mental health, they added.
Their interest in consumers’ shopping bags followed a series of studies in the Danish media. The studies suggested that wine drinkers ran a lower risk of cardiovascular (心血管的) disease and some types of cancer than beer drinkers.
小题1:The passage mainly tells us that wine drinkers ______.
A.eat more vegetables than beer drinkers
B.usually buy healthier food than beer drinkers
C.are mostly healthier than beer drinkers
D.run a lower risk of diseases than beer drinkers
小题2:According to the passage, beer buyers are less likely to buy ______.

A Brown University sleep researcher has some advice for people who run high schools: Don’t start classes so early in the morning. It may not be that the students who nod off at their desks are lazy. And it may not be that their parents have failed to enforce (确保) bedtime. Instead, it may be that biologically these sleepyhead students aren’t used to the early hour.
“Maybe these kids are being asked to rise at the wrong time for their bodies,” says Mary Carskadon, a professor looking at problem of adolescent  (青春期的) sleep at Brown’s School of Medicine.
Carskadon is trying to understand more about the effects of early school time in adolescents. And, at a more basic level. she and her team are trying to learn more about how the biological changes of adolescence affect sleep needs and patterns.
Carskadon says her work suggests that adolescents may need more sleep than they did at childhood, no less, as commonly thought.
Sleep patterns change during adolescence, as any parent of an adolescent can prove. Most adolescents prefer to stay up later at nigh and sleep later in the morning. But it’s not just a matter of choice –their bodies are going through a change of sleep patters.

Patients and doctors alike have long believed in the healing (治疗) power of humor. It is claimed that humor not only affects patients’ moods, but can actually help them recover faster.
Several studies seem to support this. Patients in better spirits are known to have higher immune cell counts. Some have even claimed to have healed themselves of serious illnesses by reading comics and watching comedies.
Despite all this, many researchers are not convinced. They point out the fact that many sufferings have been known to disappear naturally, with or without a daily dose of laughter. They also say that while optimism in general does seem to be related to better health, it is hard to tell which comes first.
Humor in times of stress, however, clearly makes us feel better. On one level, it takes our minds off our troubles and relaxes us. On another, it releases powerful endorphins, a chemical produced by your body that reduces pain.
There are cases where the appreciation of a good joke is indeed directly related to a person’s health. It can show, for example, whether a person has suffered damage to one particular area of the brain: the right frontal lobe (额叶).
Scientists confirmed this by having people read jokes and asking them to choose the funniest endings from a list. Subjects with normal brains usually chose endings that were based on a relatively complex synthesis (综合) of ideas. Subjects with specifically located brain damage, however, responded only to slapstick (闹剧) endings, which did not depend on a particular context. When pressed, the brain-damaged subjects saw the logic in the correct endings. They simply did not find them funny.
Of course, humor is largely an individual matter. Next time your friend does not get one of your jokes, there is no need to accuse him of being a lamebrain. However, you might suggest that he lighten up—for the health of it.
