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.

The latest research suggests that the key factor separating geniuses from the merely accomplished is not I.Q., a generally bad predictor of success. Instead, it’s purposeful practice. Top performers spend more hours practising their craft. It you wanted to picture how a typical genius might develop, you’d take a girl who possessed a slightly above average language ability. It wouldn’t have to be a big talent, just enough so that she might gain some sense of distinction. Then you would want her to meet, say, a novelist, who coincidentally shared some similar qualities. Maybe the writer was from the same town, had the same family background, or shared the same birthday.
This contact would give the girl a vision of her future self. It would hive her some idea of a fascinating circle who might someday join. It would also help if one of her parents died when she was 12, giving her a strong sense of insecurity and fuelling a desperate need for success. Armed with this ambition, she would read novels and life stories of writers without end. This would give her a primary knowledge of her field. She’s be able to see new writing in deeper ways and quickly understand its inner workings.
Then she would practise writing. Her practice would be slow, painstaking and error-focused. By practising in this way, he delays the automatizing process. Her mind wants to turn conscious, newly learned skills into unconscious. Automatically performed skills. By practising slowly, by breaking skills down into tiny parts and repeating, she forces the brain to internalize a better pattern of performance. Then she would find an adviser who would provide a constant stream of feedback, viewing her performance form the outside, correcting the smallest errors, pushing her to take on tougher challenges. By now she is redoing problems—how do I get characters into a room—dozens and dozens of times. She is establishing habits of thought she can call upon in order to understand or solve future problems.
The primary quality our young writer possesses is not some mysterious genius. It’s the ability to develop a purposeful, laborious and boring practice routine; the latest research takes some of the magic out of great achievement. But it underlines a fact that is often neglected. Public discussion is affected by genetics and what we’re “hard-wired” to do. And it’s true that genes play a role in our capabilities. But the brain is also very plastic. We construct ourselves through behaviour.The passage mainly deals with________.
A.the function of I.Q. in cultivating a writer |
B.the relationship between genius and success |
C.the decisive factor in making a genius |
D.the way of gaining some sense of distinction |
By reading novels and writers’ stories, the girl could________.
A.come to understand the inner structure of writing |
B.join a fascinating circle of writers someday |
C.share with a novelist her likes and dislikes |
D.learn from the living examples to establish a sense of security |
In the girl’s long painstaking training process, ________.
A.her adviser forms a primary challenging force to her success. |
B.her writing turns into an automatic pattern of performance |
C.she acquires the magic of some great achievement |
D.she comes to realize she is “hard-wired” to write |
What can be concluded from the passage?
A.A fuelling ambition plays a leading role in one’s success |
B.A responsible adviser is more important than the knowledge of writing. |
C.As to the growth of a genius, I.Q. Doesn’t matter, but just his|her effort. |
D.What really matters is what you do rather then who you are. |
“Get your hands off me, I have been stolen,” the laptop, a portable computer, shouted. That is a new solution to laptop computer theft: a program that lets owners give their property a voice when it has been taken.
The program allows users to display alerts on the missing computer’s screen and even to set a spoken message. Tracking software for stolen laptops has been on the market for some time, but this is thought to be the first that allows owners to give the thief a piece of their mind.
Owners must report their laptop missing by visiting a website, which sends a message to the model: a red and yellow “lost or stolen” sign appears on its screen when it is started. Under the latest version(版本)of the software, users can also send a spoken message.
The message can be set to reappear every 30 seconds, no matter how many times the thief closes it.” One customer sent a message saying,’ You are being tracked. I am right at your door’,” said Carrie Hafeman, chief executive of the company which produces the program, Retriever.
In the latest version, people can add a spoken message. For example, the laptop’s speakers will say: “Help, this laptop is reported lost or stolen. If you are not my owner, report me now.”
The Retriever software package, which costs $29.95 but has a free trial period, has the functions of many security software programs .Owners can remotely switch to an alternative password if they fear that the thief has also got hold of the access details.
If a thief accesses the internet with the stolen laptop, Retriever will collect information on the internet service provider in use, so that the police can be alerted to its location.
Thousands of laptops are stolen every year form homes and offices, but with the use of laptops increasing, the number stolen while their owners are out and about has been rising sharply.
Other security software allows users to erase data remotely or lock down the computer. The expression “to give the thief a piece of their mind “can be understood as “_______”
A.to give the thief an alert mind |
B.to express the owners’ anger to the thief |
C.to remind the thief of this conscience |
D.to make the thief give up his mind |
Different from other security software, Retriever can_______.
A.record the stealing process | B.help recognize the lost laptop |
C.lock down the computer remotely | D.send a spoken message |
One function of the program is that it allows the owner to _______ at a distance.
A.change some access details for switching on the laptop |
B.turn on the laptop by using the original password |
C.operate the laptop by means of and alternative password |
D.erase the information kept in the stolen laptop |
Which of the following can best summarize the main idea of the passage?
A.With no Retriever, thousands of laptops are stolen every year. |
B.A new soft ware provides a means to reduce laptop theft. |
C.Retriever has helped to find thieves and lost computers. |
D.A new program offers a communication platform with the thief. |
Welcome to Banff, Canada’s first, most famous and arguably most fascinating national park. If you’ve come to ski or snowboard, we’ll see you on the slopes. Skiing is a local favourite too.
While you’re here, try other recreational activities available in our mountains. Popular choices include a Banff Gondola ride up Sulphur Mountain, bathe in the natural mineral waters at the Upper Hot Spring, horse-drawn sleigh ride, drive-your-own-team dog sled excursion, and snowmobile tour to the highland(but not in the national park).
We also recommend you make time to enjoy simple pleasures. After looking around Banff Ave shops, walk a couple of blocks west or south to the scenic Bow River.
True ice skating on frozen Lake Louise where Ice Magic International Ice Sculpture Competition Works are displayed after Jan 25. You can rent skates in Banff or at the sport shop in the Fairmont Chateau Lake Louise hotel.
Banff’s backcountry paths access a wilderness world of silence and matchless beauty—cross country skis and snowshoes provide the means. Banff sport shops rent equipment and clothes, or join an organized tour. Although we’ve been many times, we still find the cliffs and icefalls of our frozen canyons worth visiting.
Wildlife watching also creates satisfying memories. We have seen hundreds of the elk and bighorn sheep that attract visitors, yet they still arouse a sense of wonder. And the rare spotting of a cougar, wolf or woodland caribou takes our breath away.
See if simple pleasure work for your Fight in the snow with your kids, walk beside a stream or climb to a high place and admire the view.
