A new study suggests that the more teenagers watch television, the more likely they are to develop depression as young adults .

The researchers used a national long-term survey of adolescent（青少年的）health to investigate （调查）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 2000.

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 2007, more than seven percent of the young people had signs of depression. The average age at that time was twenty-one.

The researchers say they did not find any such relationship with the use of other media such as movies, video games or radio, etc. But the study did find that every extra hour of television meant an eight percent increase in the chances of developing signs of depression. Young men were more likely than young women to develop depression given the same amount of media use.

The study didn't explore if watching TV causes depression. But one possibility is that it was taking time away from activities that could help prevent depression.

Last 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.

1.The best title for this passage should be____________.

　A. Teens, Television and Depression

　B. Men Develop Depression Easier than Women

　C. Media Use is Harmful to Adolescents

　D. Take Great Care of Teenager's Depression

2.The result of the research seems to prove______________.

　A. teenagers are more likely to develop depression than adults

　B. other media uses do no harm to adolescents

　C. TV probably causes teenagers to grow up with depression

　D. those who watch no TV will not develop depression

3.We can learn from the survey that of all the media use

　A. computer games are teenagers' favourite

　B. most teenagers prefer to listen to the radio

　C. teenagers enjoy watching TV very much

　D. newspaper is not included in the survey

4.We can conclude that a teenager should _____

　A. play more video games instead of watching TV

　B. be active in taking part in outdoor activities

　C. be more active in watching educational TV programmes

　D. attend religious services and care for politics

Working out can help teenagers boost their grades, a new study suggests. Adolescents who routinely engaged in moderate to vigorous（剧烈的）exercise showed long-term improvements in their academic performance, the British Journal of Sports Medicine study reported.

“Our study suggests that the effect of physical activity may be quite large,” John Reilly, a professor at the University of Strathclyde said. The researchers looked at a sample of about 5000 children who were involved in a long-term study that tracks children born in the UK between 1991 and 1992. When children reached 11 years old, their daily physical activity levels were measured using an accelerometer（加速器）for three to seven days. The device, similar to a pedometer（计步器）tracking the number of steps taken, recorded the average time children exercised, which was 29 minutes a day for boys and 18 for girls.

“The actual levels of daily physical activity at age 11 were quite low,” Mr. Reilly noted. The children had their academic performance tested at ages 11 and 13 with compulsory national tests for students, and also at 15 or 16 with the General Certificate of Secondary Education (GCSE) exam. The tests assessed the children’s abilities in English, math and science subjects. The results showed that the more children participated in moderate to vigorous physical activity, the higher their test scores were at age 11 in all three subjects. For girls, science scores were most strongly linked to exercise.

When children were tested again at age 13, their academic scores were still linked to how much they had exercised when they were 11 years old. By the time the youngsters took the GCSE exam, each 17-minute-per‑day increase in physical activity for the boys was linked to an improvement in their scores. Every additional 12-minute increase a day in exercise for the girls was also linked to an increased score, especially in the science category.

The researchers have called for more studies to look at the possible academic benefits that could be derived if students exercised the recommended 60 minutes or more a day.

1.What’s the study about?

A.The influence of exercise on students’ scores.

B.The secrets of students’ ranking high in class.

C.The causes of students’ participating in sports.

D.The ways of improving students’ physical conditions.

2.What is the function of the device used in the study?

A.To record how long students exercise.

B.To record the walking speed of students.

C.To record how many steps students walk.

D.To record the number of calories students consume.

3.What do the study’s results show?

A.Students at age 11 do more exercise than at other ages.

B.Boys at age 13 get more benefits by doing more exercise.

C.Girls’ science scores are more closely related to exercise.

D.More and more students do exercise to improve their scores.

4.What does the underlined word “derived” probably mean in the last paragraph?

A.adopted. B.acquired.

Less TV Reduce Kids Weight

PALO AITO, California—“Switching off the television may help prevent children from getting fatter—even if they do not change their diet or increase the amount they exercise,” US researchers said last week.

A study of 192 third and fourth grades, generally aged eight and nine, found that children who cut the number of hours spent watching television gained nearly two pounds （0.91 kg） less over a one-year period than those who did not change their television diet.

“The findings are important because they show that weight loss can only be the result of a reduction in television viewing and not any other activity,” said Thomas Robinson, a pediatrician （儿科专家）at Stanford University.

“ American children spend an average of more than four hours per day watching television and videos or playing games, and rates of childhood being very fat have doubled over the past 20 years,” Robinson said.

In the study, presented this week to the Pediatric Academic Societies’ annual meeting in San Francisco, the researchers persuaded about 100 of the students to reduce their television viewing by one-quarter to one-third.

Children watching fewer hours of television showed a significantly smaller increase in waist size and had less body fat than other students who continue their normal television viewing, even though neither group ate a special diet nor took part in any extra exercise.

“One explanation for the weight loss could be the children unstuck to the television may simply have been moving around and burning off calories,” Robinson said.

“Another reason might be due to eating fewer meals in front of the television. Some studies have suggested that eating in front of the TV encourages people to eat more,” Robinson added.

1. The author tries to tell us in the first two paragraphs that ____.

2. According to the passage, the time American children usually spend on watching TV ____.

3.Which of the following is right ?

4.Why can watching TV increase kids’ weight according to the passage ?

We smile because we are happy, and we frown because we are sad. Recent studies suggest that our emotions are driven by their related facial expressions.

This February psychologists at the University of Cardiff in W ales found that people whose ability to frown is lessened by botox injections (肉毒杆菌注射) are happier, on average, than people who can frown. The researchers administered an anxiety and depression questionnaire to 25 females, half of whom had received botox injections to stop frowning. The botox injected people reported feeling happier and less anxious in general.

In a related study from March, scientists at the Technical University of Munich in Germany scanned botox injected people with FMRI machines while asking them to copy angry faces. They found that the botox subjects had much lower activity in the brain circuits (回路) involved in emotional processing and responses - in the amygdala, hypothalamus and other parts of the brain - as compared with controls who had not received treatment.

The concept works the opposite way, too. People who frown during an unpleasant procedure report feeling more pain than those who do not, according to a study published in May 2008 in the Journal of Pain. Researchers applied heat to the forearms of 29 participants, who were asked to either make unhappy, neutral or relaxed faces during the procedure. Those who exhibited negative expressions reported being in more pain than the other two groups.

No one yet knows why our facial expressions influence our emotions as they seem to. The associations in our mind between how we feel and how we react may be so strong that our expressions simply end up strengthen our emotions - there may be no evolutionary reason for the connection. Even so, our faces do seem to communicate our states of mind not only to others but also to ourselves. “I smile, so I must be happy,” Grob says.

1.What can we know about the result of the study from paragraph 2?

A.The ability to frown should be stopped by injection.

B.Less frowns make people happier.

C.Women love to frown and feel sad.

D.Half women have no ability to feel happy.

2.What did scientists do in the related studies?

A.They asked the participants to frown or smile.

B.They copied the expressions of the participants.

C.They asked the participants to stay negative.

D.They exposed the participants to heat.

3.What does the passage talk about?

A.Facial expressions influence our emotions. B.Facial expressions are driven by emotions.

C.Why people feel happy and frown. D.Botox injection is useful and meaningful.
