2.Scientists have linked the"fat gene"with the"happy gene".They believed there could be genetic evidence which explains why fat people are often happier than their skinny friends.The breakthrough could be an explanation for why fat characters,such as The Laughing Policeman and Father Christmas are often portrayed as joyful and kindly.FTO is the major genetic contributor to obesity.But it is also associated with an eight percent reduction in the risk of depression.Researchers at McMaster University in Canada had been investigating whether there was a link between obesity and depression.They found the opposite was true.
The study analyzed 17,200DNA samples from participants in 21countries.Results showed people with FTO gene-the fat gene-showed significantly less signs of depression.This finding was confirmed by analyzing in three additional international studies.
Professor David Meyre said,"We set out to follow a different path,starting from the assumption that both depression and obesity deal with brain activity.We thought that obesity genes may be linked to depression.The difference of eight percent is not very obvious.But,we have discovered a molecular(分子的)basis for depression.It is the first evidence that an FTO obesity gene is associated with protection against major depression.
In a recent interview,actress Lisa Riley said she was more than comfortable with her size.She said she is a"big,really happy"girl who is lucky enough to be confident in her own skin,and added,"Many people want to be thinner.Not me.""I genuinely love being different and it drives me mad that people don't believe I'm happy with what I am."

分析 本文主要介绍了科学家们对人们的"肥胖基因"与"幸福基因"关系的研究发现(即FTO肥胖基因与防止重性抑郁症相关联,带有FTO肥胖基因的人得抑郁症的迹象明显要比瘦弱的人少得多).
解答 答案:
41.B 词义猜测题 根据第一段中的"…why fat people are often happier than their skinny friends"可知,此处比较的对象是:fat people 与their skinny friends,因此可猜测出 skinny 应与fat互为反义词;故选B.
42.B 细节理解题 根据第三段中的"Results showed people with FTO gene-the fat gene-showed significantly less signs of depression.结果显示:带有 FTO基因也就是肥胖基因的人得抑郁症的迹象明显要少得多"可知,FTO基因指的就是肥胖基因;故选B.
43.D 内容归纳题 根据第四段中的最后一句"It is the first evidence that an FTO obesity gene is associated with protection against major depression.这是第一次有证据表明:FTO肥胖基因与防止重性抑郁症相关联"可知,答案D.以前没有证据表明FTO肥胖基因所起的作用;故选D.
44.A 内容归纳题 通读最后一段可知,本段介绍了女演员Lisa Riley虽然比较胖,但却非常的自信与幸福,旨在证实了科学家们的研究发现即:带有 FTO基因也就是肥胖基因的人得抑郁症的迹象明显要少得多,也就是说:肥胖的人要更幸福些;故选A.
45.C 内容归纳题 根据本文主要介绍了人们的"肥胖基因"与"幸福基因"的关系可知,它应该是节选自一本健康杂志;故选C.
点评 做本题时,首先应快速浏览全文,把握文章的大意以及作者的写作思路;其次,可以通过对相关细节的理解,概括段落大意,以及通过逻辑推理或内容归纳,选出正确的答案.
