Question

【题目】In a time when a dangerous number of people are overweight, many people seem to have forgotten the most important way to keep healthy and slim---exercise. And as a new study carried out on mice in the lab has shown, exercise done early in life can reward you in your adult years.

A team of researchers at the University of California studied the effects of early exercise on adult physical activity, body mass and eating. They found that early-age exercise in mice has positive effects on adult levels of voluntary exercise in addition to reducing body mass.

“These results may have an effect on the importance of regular physical education in elementary and middle schools,” said Theodore Garland, a professor of biology, who led the research project. “If kids exercise regularly through their school years, then they may be more likely to exercise as adults, which could have far-reaching positive effects on human health and well-being.”

Although the positive effects of early-life exercise lasted for only one week, it is important to note that one week in the life of a mouse is the same as about nine months for humans. “Our results suggest that any positive effects of early-life exercise on adult exercise will need to be kept up if they are to be long-lasting.”

His team of researchers found, too, that all mice that had access to early exercise were lighter in weight than non-exercised mice.

Garland explained that, in general, exercise will stimulate appetite sooner or later. However, it is possible that certain types of exercise, done for certain periods of time or at certain light levels, might not stimulate appetite much, if at all, at least in some individuals.

“If we could understand what sorts of exercise these might be, then we might be able to tailor exercise recommendations in a way that would bring the benefits of exercise without increase in appetite, leading to a better chance of weight loss,” he said.

B. Early-life exercise has life-long positive effects on people

C. Kids should be encouraged to do exercise as early as possible to ensure physical health.

D. The new study on mice mainly focused on how exercise affects appetite.

【3】The underlined word “stimulate” in the last but one paragraph is closest in meaning to _______.

A. decline B. improve C. vary D. harm

【4】 What is the article mainly about?

A. New ways to fight against being overweight.

B. The positive effects of mice

C.The possible risks of doing exercise

D. The positive effects of early- life exercise.

Answer 1

【答案】

【1】B

【2】A

【3】B

【4】D

【解析】

试题分析:文章讲述了研究人员以小白鼠做实验，证实人类在早年做规律性的运动，会收到很好的效果。

【1】B考察细节理解题。根据文意Although the positive effects of early-life exercise lasted for only one week可知小白鼠在试验中的积极影响持续了一个星期，所以答案是B。

【2】A考察细节理解题。根据文意If we could understand what sorts of exercise these might be, then we might be able to tailor exercise recommendations in a way that would bring the benefits of exercise without increase in appetite, leading to a better chance of weight loss可知如果我们对不同种类的运动都有了解，那么我们就能选择一种适合自己的，所以要增加这方面的研究，所以答案是A。

【3】 B考察细节理解题。根据文意in general, exercise will stimulate appetite sooner or later. However, it is possible that certain types of exercise, done for certain periods of time or at certain light levels, might not stimulate appetite much, if at all, at least in some individuals可知一般而言，运动会多少刺激人们的食物，但是对于有些人而言也会有例外，不能提高他们的食欲，所以该词的意思是“提高”，所以答案是B。

【4】D考察主旨大意。文章讲述了研究人员以小白鼠做实验，证实人类在早年做规律性的运动，会收到很好的效果，鼓励人们要多加运动，所以答案是D。
