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 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.

When the mother turned 16 the sound of her son’s crying she saw that his 17 was in the vase and was apparently stuck. She 18 to help him and pulled and pulled until the child cried out 19 . But the hand was stuck fast（牢固地）. How would they get it out? The father suggested 20 the vase but it was quite valuable and the child’s hand might be cut in the 21 _. Yet he knew that if all else 22 there would be no other alternative.

The father said to the boy, “What are you holding onto so tightly as to hinder (阻碍) your walk with God? That vase can be 31 to the entrance to the Kingdom of God. It is narrow yet quite 32 to pass in, but first you must open your hand to God and 33 earthly（世俗的）things to fall. If we keep our fists 34 and hold fast to what we have and keep it for ourselves, we will be unable to 35 hold of the hand of God. Open your hand to the hand of God and you will see great things take place.”
