　　PALOALTO, California--Turning off the television may help prevent children from getting fatter, even if they do not change their diet or increase the amount of their exercise.”US researchers said last week.

　　A study of 192 third and fourth graders, generally aged eight and nine, found that children who cut the number of hours spent watching television gained nearly two pounds, or 0.91 kilogram 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 the reducing of watching TV and not any other activity,”said Thomas Robinson, a pediatrician (兒科專家)at Stanford University.

　　“American children spend an average of more than four hours per day watching television and videos and playing video games, and rates of childhood being 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 smaller increase in waist size and had less body fat than other students who continued 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 unattracted to the television may simply have been moving around more and burning off calories.”said Robinson.

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

[　　]

A．children will get fatter if they spend more time watching TV

B．children will get fatter if they spend less time watching TV

C．children will get fatter if they eat too much

[　　]

A．is more than four hours a day

B．is more than on any other activities

C．is less than four hours a day

D．doubled in the last twenty years

3．It is suggested that the time children spend watching every day should be about ________.

[　　]

A．six hours
B．three hours
C．one-quarter of a day
D．one hour

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

[　　]

　　If you have been joining in chat room conversations, or trading email with web pals(網(wǎng)友), you have become one of the millions who write in a particularly short form of English．

　　And you’re got a sense of humor about short forms like SOHF(＝sense of humor failure)to describe Internet newcomers who don’t understand you．

　　Across the globe, every night teenagers and their eldersare “talking” online, many of them all talking at the same time．

　　It’s fast：try talking to six people at once．It’s brief：three or four words per exchange．It takes wit, concentration and quick fingers．

　　And it requires tremendous linguistic economy(語言省略)．There’s neither time nor space for explanations．Why consume precious key-strokes(鍵盤敲擊)telling six friends you have to leave for a moment to take care of your little brother when BRB(＝be right back)will do?

　　Want to enter a conversation? Just type PMFJI(＝pardon me for jump in)．

　　Interested in whom you are talking to? Type A/S/L, the nearly universal request to know your pal’s age, sex and location．You might get 15/M/NY as a response from your pal．

　　If something makes you laugh, say you are OTE(＝on the floor), or LOL(＝laughing out loud), or combing the two into ROTFL(＝rolling on the floor laughing)．

　　And when it is time to get back to work or go to bed, you type GTG(got to go)or TTYL(＝talk to you later)．

　　People want to write as fast as possible, and they want to get their ideas across as quickly as they can．Capital letters are left in the dust, except when expressing emotion, as it takes, more time to hold down the “shift” key and capitals．Punctuation(標(biāo)點)is going, too．
