[1]People with lower intelligence are more likely to be unhappy than their brighter colleagues, according to UK researchers, Their study of 6,870 people showed low intelligence was often linked with lower income and poor mental health, which contributed to unhappiness. The researchers are calling for more help and support to be targeted at people with lower IQs. Their findings were published in the journal Psychological Medicine.
[2]The researchers analyzed data from the Adult Psychiatric Morbity Survey in England. One of the questions was：“Taking all things together, how would you say you were these days—very happy ,fairly happy or not too happy?” The highest part saying they were “ ”was found in people with an IQ between 120 and 129-43% said they were very happy..
[3]However, the highest proportion saying “not too happy”was found in people with an IQ between 70 and 79. The study said lower intelligence was linked to lower income, worse health and needing help with daily life, such as shopping or housework—all of which contributed to unhappiness.
[4]Dr Hassiotis said：“There is some evidence that long term strategies directed at young children from poor backgrounds can have a positive impact on IQ, wellbeing and life opportunities”. Such interventions(干涉)are likely to be costly, but the initial costs may be offset（抵消）by future benefits such as a reduced reliance on state benefits and better mental and physical health”.
[5]He added that the study was particularly helpful as it identified some of the factors（因素）that influence the association between IQ and happiness. The study also emphasized the interventions to prevent lower IQ leading to greater unhappiness.

(答案→)The association between IQ and happiness. 解析：智商的高低会对幸福水平产生影响【小题1】主旨题：从文章最后一段的句子：He added that the study was particularly helpful as it identified some of the factors（因素）that influence the association between IQ and happiness. 可知这篇文章讲的是智商的高低和幸福感的联系，The association between IQ and happiness. 【小题2】填词题：从后面的句子：was found in people with an IQ between 120 and 129-43% said they were very happy..可知这些是非常快乐： Very happy【小题3】细节题：从倒数第二段的句子：Such interventions(干涉)are likely to be costly, but the initial costs may be offset（抵消）by future benefits such as a reduced reliance on state benefits and better mental and physical health”.可知这些内在的花费会和未来的利益抵消。填Because the initial costs may be offset by future benefits.【小题4】推理题：从最后一段的句子：The study also emphasized the interventions to prevent lower IQ leading to greater unhappiness.可知干预是很必要的。 The interventions are necessary.【小题5】这是定语从句，所以which指代的是前面的：Lower income and poor mental health.
