问题     Overweight has become a problem people all around the world face, and it does not look like it will be solved in the near future regardless of the various efforts from all walks of life. And for those who have a heavier body than they are supposed to, one advice is given repeatedly: eat less and exercise more. This has long been the suggestion for getting rid of those extra pounds. But now it seems that all the hard work may have been in vain. Scientists say there are ten other reasons why people just keep getting bigger.
    Scientists claim that sleeping habits, central heating, medicines and even some pollutants can play a role in weight gain. Lack of sleep could be partly to blame. In recent years, the average night’s sleep has dropped from nine hours to just seven. Sleep lack changes levels of the hormones that regulate food intake and body fat and increase hunger and appetite.
    If it is too hot or too cold, we burn calories to cool down or heat up. But if the temperature is just right, the calories may be turned into body fat instead.
    Those who take medicines to control their blood pressure can often put on more weight. Similarly, studies have shown that going on the Pill can add to a woman’s weight. Mother Nature may also be to blame, with our body shape being partly determined by our parents. The overweight are also more likely to be associated with partners of a similar size, and their children are more likely to be overweight.
    The scientists from Yale, Cornell and Johns Hopkins published their analysis of these findings last week. Their reasoning goes like this:
1. Sleep--Too little increases appetite.
2. Medicine--Many modern medicines lead to us putting on weight.
3. Mother’s age--Older women are more likely to have obese children.
4. Giving up smoking--Nicotine suppresses the appetite.
5. Getting older--Weight tends to increase with age.
选项 A、It may not be a solution for all who face this problem since the reasons for people’s getting fat varies.
B、There are various other ways to achieve the goal of weight-loss and this is not the best one.
C、Exercise is something you will never get your returns and your efforts will be in vain.
D、It has been talked about for too long a time that a newer alternative is needed.
答案A
解析 考查作者对文中某个观点的态度。也需要我们在结合对全文核心议题的把握基础上进行解答。文章是在讨论造成肥胖的种种原因，所以首段的内容一定是在为这个中心议题服务的，借此我们就可以判断出A是正确答案；B借用了原文的various一词编造了不存在的观点；C项对原文的“all the hard work may have been in vain”进行了曲解，原文的意思是“运动可能是无效的”，但其背后的原因在于“造成肥胖的原因多种多样”，只有正确的理解这一点才能正确作答，提醒考生在解答任何问题的时候都不能忘记文章的主题，无论选项多么具有迷惑性，只要脱离了文章的主题，都是不能选的；D项的设置在于对原文的repeatedly一词的曲解。
