Spending a lot of time watching TV, playing video games and surfing the Web causes a lot of healthy problems to children such as overweight and smoking, US researchers said yesterday.

U.S. experts analyzed 173 studies on how media sources influence the physical health of children and adolescents (青少年). The studies, mostly carried out in the United States, largely focused on television, but some looked at video games, films, music, computer and Internet use. Three quarters of them found that increased media viewing was connected with poor health.

The studies offered strong evidence that children who get more media exposure are more likely to become overweight, start smoking and begin earlier sexual activity than those who spend less time in front of a screen, the researchers said. Studies also showed more media exposure is linked to drug and alcohol use and poorer school performance. “We were pretty surprised by the number of studies that showed these negative health results,” said one of the researchers in the report.

For decades, experts have worried about the effect on young viewers of the violence and sexual content in some TV programs, movies and video games. Another issue is that kids are spending time sitting on a couch（长沙发) watching TV or playing computer games when they could be running around outside.

One study found that children who spend more than eight hours watching TV per week at age 3 are more likely to be overweight at 7. And research showed that many US children watch far more. Another study showed TV and other media content can have a deep influence on children’s attitudes and beliefs, particularly among teens. A US study published in November showed that adolescents who watched more programs with sexual themes had a higher risk of becoming pregnant (怀孕的) or causing a pregnancy. Thirteen of 14 studies that evaluated (评估）sexual behavior found a connection between media exposure and earlier sexual behavior, the researchers said.

A. By examining health problems including overweight and smoking.

B. By analyzing 173 studies on influences of media sources.

C. By watching TV, playing video games and surfing the Web.

D. By offering strong evidence that children become overweight.

A. drug and alcohol use                                    B. overweight, smoking, sexual problem

Shaping the Future of TV
Nobody can predict the future of TV with any certainty but some major figures in the industry have recently put forward their thoughts on what will shape TV of the future.
The shaping of a personalized television future is starting to take place, says Intel. The chip giant, who makes the processors found in most personal computers, states that by 2015 there will be just over 12 million devices using IPTV services that will be capable of connecting to over 500 billion hours of TV & video.
This supports the idea to make television a more social, personalized and readily accessible device available anywhere through IPTV services. As more and more people consume TV & video through various mediums, there is now a greater need to distribute and manage this content.
As such, companies like TV Genius are accepting this announcement made at Intel’s Developer Forum (IDF) in the USA by their chief technology officer, Justin Rattner.
With such a variety of content likely to become available, technology firms will need to assist in making personalized TV recommendations more readily accessible.
Mr. Rattner, speaking to the BBC said, “TV will remain at the centre of our lives and you will be able to watch what you want and where you want. We are talking about more than one TV-capable device for every man and woman on the planet. People are going to feel connected to the screen in ways they haven’t in the past.”
One way in which this will happen will also be assisted by a more united service of material combining including video content, internet content, broadcast content, and personal content.
This content will become much more accessible through remote devices like mobile phones using IPTV technology. This means that users will be able to watch their favorite programs away from the traditional media hub, the home.
63. The author uses the passage mainly to ________.
A. recommend a new type of TV          B. introduce a possible shape of future TV
C. describe the function of future TV    D. support the new type of TV
64. We know from the passage that the future TV might have major features like _______.
a. being capable of connecting to many more hours
b. changing the shape very easily        c. receiving programs at any place
d. displaying the advanced materials
e. using services accessing the Internet, video, radio, etc
A. a, b, c  B. c, d, e     C. a, c, e     D. b, c, e
65. The underlined word “this” in the third paragraph refers to __________.
A. Intel, the chip giant                  B. TV and video
C. readily accessible device            D. Widely used IPTV services
66. We can infer from the passage that _________.
A. the present TV will disappear in the near future
B. the future TV will have a beautiful look
C. people are developing the technology of TV very quickly
D. people will spend more time watching TV at home
