"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 graders, generally aged eight and nine, found that children who cut the number of hours spent watching television gained nearly two pounds 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. American children spend an average of more than four hours per day watching television and videos or playing video games, and rates of childhood being very fat have doubled over the past 20 years.
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 continued their normal television viewing, even though neither group ate a special diet or 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 more and burning off calories. 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.
26. What do we know about the findings of the study?
27. Why are the findings important?
28. What accounts for the findings?
选项
A、Because they prove the direct effect of reduction in television viewing.
B、Because they show the great importance of physical activity.
C、Because they help settle on the best diet small children need.
D、Because they indicate that children benefit much from TV programs.
答案
A
解析
细节题。短文提到,研究结果很重要,因为它们显示了体重的减少只会是看电视减少的结果,而不是任何其他活动导致的。由此可判断。A为正确答案。
