题目内容
17.Weighing too much can be bad for your health,and being fat is a growing problem for both kids and adults around the world.In the U.S today,about 9million children over the age of 6are fat.Sleep might be one answer to the problem of being fat.Past studies have shown a relation between sleeping less and weighing more,but scientists have had a hard time deciding"which came first,the chicken or the egg?"
To get a better idea of which cause which,scientists interviewed the parents of 785third grade students about how well their kids sleep that year.Three years later,the parents answered the same questions.
By sixth grade,18% of these kids were fat.The scientists found no relationship between weight and the students'race or sex.It also didn't matter how strict their parents were,or whether they were boys or girls.Being fat is a problem of these group equally.
Instead,sleep seemed to be the main reason.For the six grade students,every night of sleep above the 9.5-hour average caused a 20% lower risk of being fat.Sleep appeared more important for the third grade students.One more hour of sleep they get led to 40% less in fatness before third grade.

分析 体重太沉可能对你的健康不好,并且肥胖对全世界的孩子和成年人来说都正成为一个难题.在今天的美国,大约有9百万六岁的孩子是肥胖的.
睡眠可能是肥胖的原因之一.之前的研究已经表明睡眠少与体重沉之间的关系,但是科学家们很难决定"先有鸡还是先有蛋?"
为了更好的理解哪一个引起了哪一个,科学家们采访了785名三年级学生的家长,咨询他们去年孩子的睡眠怎样.三年后,这些父母回答了相同的问题.
等到了六年级的时候,这些孩子中的百分之十八是胖的.科学家们发现在体重与学生的种族与性别没有关系.也与他们父母的严厉程度或他们是男孩或女孩无关.肥胖是这群人面临的同样问题.
相反的,睡眠似乎是一个主要的原因.对于六年级的学生们来说,每晚超过九个半小时的睡眠平均有百分之二十的低肥胖率.睡眠对于三年级的学生来说更重要.在三年级之前,他们每多睡一小时会降低百分之四十的肥胖.
解答 66.C 结合全文总结大意题.根据文章第二段第二句"Past studies have shown a relation between sleeping less and weighing more."(之前的研究已经表明睡眠少与体重沉之间的关系)及文章第五段第一句"sleep seemed to be the main reason"(睡眠似乎是一个主要的原因)知文章的大意为睡眠少引起体重沉,故选C.
