Today, as in every other day of the year, more than 3000 U.S. adolescents will smoke their first cigarette on their way to becoming regular smokers as adults. During their lifetime, it can be expected that of these 3000 about 23 will be murdered, 30 will die in traffic accidents, and nearly 750 will be killed by a smoking-related disease. The number of deaths attributed to cigarette smoking outweighs all other factors, whether voluntary or involuntary, as a cause of death.
Since the late 1970s, when daily smoking among high school seniors reached 30 percent, smoking rates among youth have declined. While the decline is impressive, several important issues must be raised.
First, in the past several years, smoking rates among youth have declined very little. Second, in the late 1970s, smoking among male high school seniors exceeded that among female by nearly 10 percent. The statistic is reversing. Third, several recent studies have indicated high school dropouts have excessively high smoking rates, as much as 75 percent.
Finally, though significant declines in adolescent smoking have occurred in the past decade, no definite reasons for the decline exist. Within this context, the National Cancer Institute (NCI) began its current effort to determine the most effective measures to reduce smoking levels among youth.
36. According to the author, the deaths among youth are mainly caused by __________.
A. traffic accidents                                   B. smoking-related disease
C. murder                                                 D. all of these
37. Every day there are over ______ high school students who will become regular smokers.
A. 750                         B. 23                    C. 30                    D. 3000
38. By “dropout” the author means __________.
A. students who failed the examination        B. students who left school
C. students who lost their way                    D. students who were driven out of school
39. The reason for declining adolescent smoking is that __________.
A. NCI has taken effective measures           
B. smoking is prevented among high school seniors
C. there are many smokers who have died of cancer          
D. none of these
40. What is implied but not stated by the author is that __________.
A. smoking rates among youth have declined very little     
B. there are now more female than male smokers among high school seniors
C. high smoking rates are due to the increase in wealth
D. smoking at high school is from low socio-economic backgrounds

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

The researchers used a national long - term survey of adolescent 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 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.

    Previous study 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 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 don’t watch TV will not develop depression

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

    A. computer games are teenagers’ favorite

    B. most teenagers prefer to listen to the radio

    C. teenagers enjoy watching TV very much

    D. newspaper is not included in the survey

3. According to the passage, what kind of activity may help prevent depression?

    A. Playing computer games.            B. Taking part in sports.

    C. Listening to the radio.               D. Watching movies.

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
