Question

【题目】Fast food and too much TV time should not take all the blame for the weight problems. A group of researchers say that a number of aspects of modern living from lack of sleep to environmental chemicals and to living with air conditioning—may be closely related to the weight problems of many people.

Lack of sleep is one of factors. Researches in animals and humans suggest that a lack of sleep over a long time can increase appetite. Studies also show that many adults and children are sleeping less than they used to. In recent decades, adults have gone from sleeping for all average of nine hours to about seven hours.

There is also evidence that industrial chemicals may increase body fat. These chemicals, which are used in products, change hormonal(荷尔蒙的) activity when they get into the body. Studies suggest that people have been getting more and more of these chemicals through the food chain in recent decades.

Another factor that may be making people overweight is air conditioning. The body burns calories when forced to eat less in hot and wet weather, but air conditioning makes it unnecessary for the body to make any adjustment.

Researchers also list other possible risk factors for overweight, including more older mothers, whose children may become overweight more easily; a number of medicines which can lead to weight gain; and fewer people who smoke, since people often gain weight when they stop smoking because nicotine can make people eat less.

No one is suggesting that people should stop working and sleep more, or keep smoking. When it comes to saying any person’s weight, what really matters is how much they eat and how much of the food they use every day. That means diet and exercise are still the key.

【解析】

试题分析：本文主要介绍了影响肥胖的主要因素，并得出现代生活的许多方面都与很多人的体重问题密切相关的结论。

【1】推断题。由第二段中的Researches in animals and humans suggest that a lack of sleep over a long time can increase appetite. 句意为人类和动物的研究表明长时间的缺乏睡眠能够增加食欲，可以推断出缺乏睡眠导致体重问题的原因是它能增加人的食欲，故填Because it can increase appetite.

【2】细节题。由第二段中的In recent decades, adults have gone from sleeping for all average of nine hours to about seven hours.句意为在近几十年，大人的睡眠时间由平均每天九个小时变为七个小时了，可以推断出现在大人平均每天睡七个小时，故填Seven/7 hours.

【3】细节题。由第三段中的Studies suggest that people have been getting more and more of these chemicals through the food chain in recent decades.句意为研究表明近几十年，人们正通过食物链摄取越来越多的化学成分，可以推断出影响体重的工业化学成分进入我们身体的渠道，故填Through the food chain.

【4】推断题。由整篇文章的内容我们可以推断出该文章主要讲的是现代生活的许多方面都与很多人的体重问题密切相关，故填A number of aspects of modern living may be closely related to the weight problems of many people.
