4、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 doubt 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.

3、London, Reuters--What could annoy teenagers enough to make them stop hanging out with friends and go home?

No, it's not a visit from their mothers, and not a threat to take away their cellphones or pocket money.

It's high-frequency noise. The UK police recently agreed to use a device (装置) called the Sonic Teenager Deterrent. It sends out a sound that makes teenagers become so impatient and angry that they have to cover their ears tightly and walk away.

The sound is at extreme high-pitch that can be heard by those under 20. The body's natural ability to detect some wave bands (波段) decreases almost entirely after 20, so few adults can hear the sounds. The black-box device, nicknamed the Mosquito because of its sound, can be fixed to the outside walls of shops, offices and homes. It sounds to youngsters like a crazy insect or a badly played violin. But it causes no physical damage.

A number of police forces and councils have given permission to use the system and want to install it at trouble spots.

Staffordshire Police Inspector Amanda Davies, who has given the device to shopkeepers in the Moorlands area, said," It is controlled by the shopkeepers--if they can see through their window that there is a problem, they turn the device on for a while until the group has run away."

 

56. The device can be used to ____________.

A. threaten teenagers in public                                  B. drive away trouble-makers under 20

C. help mothers control their teenage children            D. help the police control shopkeepers

57. From the passage we can know that ___________.

A. young people often suffer from pains in ears

B. shopkeepers are troubled by noisy insects

C. high-frequency noise is beyond the listening ability of people' over 20

D. the police invented a new device to deal with teenagers

58. The purpose of the writer to write the passage is ________.

A. to advertise a new hi-tech device            

B. to tell the reader a piece of news

C. to sell the device to shopkeepers 

D. to inform the public as the spokesman of the police

59. Who will welcome the device most?

A. Shopkeepers.     B. The police.      C. Young people.    D. The producer.

2、You Mi, a lovely and confident 17-year-old student, is the first Chinese high school student to appear on the cover of the popular young adults’ fashion magazine Seventeen.

    “You is IN,” said Wang Lihua, Editor-in-Chief of Seventeen. “You is active and mature(成熟的) because of her knowledge on everything from academic studies,to books on art,to movies. We found she’s the very style we’re looking for to represent young people’s attitudes.”

   You also impressed Wang with her fluent English when they first met last year. As the hostess of an English broadcasting programme at the High School Affiliated to Renmin University,she is always praised for speaking English almost like a native speaker. “I’ve built up my English by watching thousands of English DVDs since I was 10,” she explained.

  But for her, watching isn’t enough. Last year,while in Senior 1,You met a talented boy who showed self-made DV movies at the English Corner in her school.

I worked on it every single day during the SARS holidays,” she recalled. The movie finally became a big hit on campus,earning You a strong reputation(名气) as a DV movie director.

  But this is not the only field she wants to master. Despite being a science student,she likes art,literature and fashion design very much.

  “There are people who can be artists,there are people who edit books,and there are people who become film producers. But I just hope to mix all the things up!” she said. “There is an old saying I believe:Chance favours only the prepared mind.”
