13.Next time you raise an eyebrow at the views of your partner,friend,sibling (兄弟姐妹) or colleague,remember they could be helping to make you smarter.
New research shows that intelligence is not fixed but can be boosted throughout adulthood by family members,bright mates and intellectually stretching (拉伸) careers.
The study challenges the commonly held belief that intelligence is static by the age of about 18.Current scientific consensus suggests that intelligence is controlled by genes,with environmental factors such as schooling and nutrition playing a partial role up to this age.After this point,IQ scores stabilize (稳定).
But James Flynn,professor of political studies and psychology at the University of Otago in New Zealand,argues that people can"upgrade"their own intelligence throughout their lives.He believes intellectual stimulation (刺激) from others is crucial as the"brain seems to be rather like a muscle-the more you use it,the stronger it gets".However,the opposite is also true-so people sharing a home or workplace with those who are intellectually challenged risk seeing their IQ levels fall as a result.
He found the"understanding quality"of a family changes the IQs of all members,especially children.It can"lift"or hold back,depending on the"gap between their brightness and that of their siblings and parents".A bright ten-year-old with brothers and sisters of average intelligence will suffer a five to ten point IQ disadvantage,compared to a similar child with equally bright siblings.However,children with a low IQ could gain six to eight points by having brighter siblings and special educational treatment to help pull them up.
Professor Flynn also concluded that although genetics and early life experiences determine about 80percent of intelligence,the remaining 20percent is linked to lifestyle.This means that people can raise their IQ,or allow it to fall,by ten points or more.Therefore,the best way to boost IQ level is to mix with bright friends,find an intellectually challenging job and marry someone cleverer.

分析 本文属于说明文阅读,作者通过这篇文章主要向我们描述了研究表明,智商不是固定的,在成年之后,你的家人、聪明的同事、可以拉伸智商的职业都会使你的智商提高.
解答 32.D.细节理解题.由第二段中的"New research shows that intelligence is not fixed but can be boosted throughout adulthood by family members,bright mates and intellectually stretching (拉伸) careers"可知,研究表明,智商不是固定的,在成年之后,你的家人、聪明的同事、可以拉伸智商的职业都会使你的智商提高.故选D.
33.B.词义猜测题.由第二段中的"New research shows that intelligence is not fixed but can be boosted throughout adulthood by family members,bright mates and intellectually stretching (拉伸) careers"可知,研究表明,智商不是固定的,在成年之后,你的家人、聪明的同事、可以拉伸智商的职业都会使你的智商提高.这一结果挑战了传统的观念"intelligence is static by the age of about 18",由此可以推知,传统观念认为,到了18岁左右,人的智商就是固定的了.故画线单词意思意为"固定的,不变的",故选B.
34.A.细节理解题.由第四段中的"James Flynn…argues that people can‘upgrade'their own intelligence throughout their lives.He believes intellectual stimulation (刺激) from others is crucial as the‘brain seems to be rather like a muscle-the more you use it,the stronger it gets'"可知,James Flynn认为,大脑就像肌肉一样,你用的越多,它就变得越强.来自别人的智商方面的刺激对智商的提高至关重要.故选A.
35.C.标题归纳题.文章第二段是文章的中心段.由第二段以及下文的详细介绍可知,研究表明,智商不是固定的,在成年之后,你的家人、聪明的同事、可以拉伸智商的职业都会使你的智商提高.故选C.
