8.Scientists fear rising energy bills may lead to an increase in obesity (肥胖) after discovering a link between poorly-heated homes and higher body-fat.Researchers from the University of Stirling's Behavioural Science Centre set out to explore claims that warm indoor temperatures have contributed to rising obesity levels in winter.Instead,the team found that people who live in well-heated homes are more likely to have low body mass index (体重指数) levels while those who keep their heating turned down or off tend to be heavier.
Dr Michael Daly,behavioral scientist and senior lecturer,said:"We set out to investigate the scientific claims that cooler indoor temperatures help us maintain a healthy weight by pushing our bodies to use up more energy.In fact,the research suggests people may eat less and burn more energy when in a warmer indoor environment.
The 13-year study,published in the journal Obesity,involved more than 100,000adults across England.
Researchers found reduced weight levels among people living in homes heated to above 23°C(73F),which involved about 15,000of the households studied.
Dr Daly said:"As national gas bills continue to rise faster than the rate of inflation,this research suggests the obesity could worsen where heating is turned down below comfortable levels or off for long periods to cut costs."
This is not just about people who live in well-heated homes being in the financial position to afford more expensive low-calorie foods,exercise classes and sporting activities,and therefore finding it easier to maintain a low BMI level.The study took age,sex,social class and other factors into account.
"The comfortable temperature of 20°C-23°C is where we feel comfortable in our clothes and are neither hot nor cold.At temperatures above this,we use more energy and we eat less because our appetite is affected."
29.The findings of the research can be described asB.
A.horrible B.surprising C.funny D.encouraging
30.According to the passage,with rising gas bills,people may turn down or off their heating toC.
A.stay in shape B.maintain a low BMI level
C.save money D.avoid eating more
31.Which of the following can be the best title for the passage?A
A.Obesity links to poorly-heated homes
B.Well-heated home's contribute to obesity
C.Obesity---A weighty problem in England
D.Rising energy bills help maintain a healthy weight.
分析 本文是一篇科教类阅读,文章主要介绍了研究人员发现肥胖和供热之间存在一定关系,由此他们认为能源成本的上涨会导致肥胖问题.因为为了节约生活费用,一些家庭在冬天关掉煤气,而较低的温度会让人们食欲增加,而且低温也消耗人们较少的能量.
解答 29---31 BCA
29.B推理判断题.根据第二段内容可知,研究人员本来是去调查冬天室内温度太高会导致肥胖问题,但是结果却发现供热好的家庭体重指数较低,而供热不好的家庭体重指数较高.由此判断,他们对调查结果会感到惊讶.故选B.
30.C细节理解题.根据倒数第三段As national gas bills continue to rise faster than the rate of inflation,this research suggests the obesity could worsen where heating is turned down below comfortable levels or off for long periods to cut costs.可知国家煤气费用上涨,于是人们关掉煤气去节约费用.由此可知,随着能源价格的上涨,人们降低或者关掉暖气主要是为了省钱.故选C.
31.A标题归纳题.本文是一篇科学研究性短文,开头提出中心 Scientists fear rising energy bills may lead to an increase in obesity (肥胖) after discovering a link between poorly-heated homes and higher body-fat.然后再进行详细介绍.由此可知,文章主要介绍了屋子保暖不好会导致肥胖的原因.故选A.
