Researchers have just offered evidence in a study that says obesity appears to spread through social ties, much like a virus. When one person gains weight, their close friends often follow. But the findings might also offer hope.
If friends help make obesity acceptable, then they might also be influential in losing the fat. The researchers note that support groups are already an effective tool in dealing with other socially influenced problems, like alcoholism.
The findings appeared in the New England Journal of Medicine. The researchers used information collected from? 12 000 people. It was collected between 1971 and 2003 as part of the Framingham Heart Study.
The information was highly detailed. There was even contact information for close friends of the people in the study.
The researchers examined more than 40 000 social ties. They found that a person’s chances of becoming severely overweight increased by 57% if a friend had become obese.
A sister or brother of a person who became obese had a 40% increased chance of becoming obese. The risk for a wife or husband was a little less than that.
Nicholas Christakis of Harvard Medical School was a lead investigator in the study. He says there is a direct causal relationship between a person getting fat and being followed in weight gain by a friend.
The study found that the sex of the friends was also an influence. In same—sex friendships, a person had a 71% increased risk of becoming obese. Men had a 44% increased risk of becoming obese after weight gain in a brother. In sisters, it was 67%.
The researchers also considered the effect of where people lived in relation to each other. James Fowler of the University of California,San Diego, was the other lead investigator. He says a friend who lives a few hundred kilometers away has as much influence as one in the same neighborhood. He says the study demonstrates the need to consider that a major part of people’s health is tied to their social connections.
Both investigators say their research shows that obesity is not just a private medical issue, but a public health problem.

A.Obesity has a negative influence on a close friend.
B.Friends might also play a part in losing weight.
C.One might have a positive influence on one’s friend.
D.Friends usually don’t follow each other to lose weight.
60.Who is mostly likely to gain weight?
A.A man who has a fat brother. B.A husband who has a fat wife.

B.If one gains weight, one’s friends are likely to get fat.
C.A person’s health is closely linked with his/her social relationship.
D.Even if the friend lives far away, the influence still remains.

Located in eastern Hangzhou,the indoor entertainment and educaion park,similar to "Kidzania" in Mexico and Japan,offers more than 50 professions,including pilot,doctor,police officer and lawyer,according to Hangzhou Youth Activity Center(HYAC),the organizer of the park,The park will be a 7:10 scale (比例尺) city with streets,hospitals,museums,supermarkets, schools,airport and other facilities.Construction has begun on the indoor section.

A new study suggests that the more teenagers watch television , the more likely they are to develop depression (抑郁)as young adults. But the extent to which TV may or may not be to blame is a question that the study leaves unanswered.
The researchers used a national long-term survey of adolescent health to investigate the relationship between media use and depression . They based their findings on more than four thousand adolescents who were not depressed when the survey began in 1995.
As part of the survey, the young people were asked how many hours of television or videos they watched daily. They were also asked how often they played computer games and listened to the radio.
Media use totaled an average of five and one-half hours a day. More than two hours of that was spent watching TV.
Seven years later, in 2002, more than seven percent of the young people had signs of depression. Their average age at that time was twenty-one.
Brian Primack at the Universtiy of Pittsburgh Medical School was the leading author of the new study . He said every extra hour of television meant an eight percent increase in the chances of developing signs of depression.
The researchers say they did not find any such relationship with the use of other media such as movies, video games or radio. But the study did find that young men were more likely than young women to develop depression given the same amount of media use.
Doctor Primack says the study did not explore if watching TV causes depression . But one possibility, like sports and socializing. It might also interfere with sleep, he says, and that could have an influence.
The study was just published in the Archives of General Psychiatry. In December, the journal Social Indicators Research published a study of activities that help lead to happy lives. Sociologists from the University of Maryland found that people who describe themselves as happy spend less time watching television than unhappy people. The study found that happy people are more likely to be socially active, to read, to attend religious services and to vote.

B.over 280 teenagers who received the survey became more or less depressed in 2002
C.men are more likely to become depressed than women
D.the study about the relationship between media use and depression was published in the journal Social Indicators Research
63.What is the best title for the passage?

It is hard to track the blue whale, the ocean’s largest creature, which has almost been killed off by commercial whaling and is now listed as an endangered species. Attaching radio devices to it is difficult, and visual sightings are too unreliable to give real insight into its behavior.
So biologists were delighted early this year when, with the help of the Navy, they were able to track a particular blue whale for 43 days, monitoring its sounds. This was possible because of the Navy’s formerly top-secret system of underwater listening devices spanning the oceans.
Tracking whales is but one example of an exciting new world just opening to civilian scientists after the cold war as the Navy starts to share and partly uncover its global network of underwater listening system built over the decades to track the ships of potential enemies.
Earth scientists announced at a news conference recently that they had used the system for closely
monitoring a deep-sea volcanic eruption (爆发) for the first time and that they plan similar studies.
Other scientists have proposed to use the network for tracking ocean currents and measuring changes in ocean and global temperatures.
The speed of sound in water is roughly one mile a second—slower than through land but faster than through air. What is most important, different layers of ocean water can act as channels for sounds, focusing them in the same way a stethoscope (听诊器) does when it carries faint noises from a patient’s chest to a doctor’s ear. This focusing is the main reason that even relatively weak sounds in the ocean, especially low-frequency ones, can often travel thousands of miles.
81. The passage is chiefly about ____ .
A. an effort to protect an endangered marine species
B. the civilian use of a military detection system
C. the exposure of a U.S. Navy top-secret weapon
D. a new way to look into the behavior of blue whales
82. The underwater listening system was originally designed ____ .
A. to trace and locate enemy vessels
B. to monitor deep-sea volcanic eruptions
C. to study the movement of ocean currents
D. to replace the global radio communications network
83. The deep-sea listening system makes use of ____ .
A. the sophisticated technology of focusing sounds under water
B. the capability of sound to travel at high speed
C. the unique property of layers of ocean water in transmitting sound
D. low-frequency sounds travelling across different layers of water____
84. It can be inferred from the passage that____.
A. new radio devices should be developed for tracking the endangered blue whales
B. blue whales are no longer endangered with the use of the new listening system
C. opinions differ as to whether civilian scientists should be allowed to use military technology
D. military technology has great potential in civilian use
85. Which of the following is true about the U.S. Navy underwater listening network?
A. It is now partly accessible to civilian scientists.
B. It has been replaced by a more advanced system.
C. It became useless to the military after the cold war.
D. It is indispensable in protecting endangered species.
