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 (體重指數(shù)) 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."

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

分析 本文是一篇科教類閱讀,文章主要介紹了研究人員發(fā)現(xiàn)肥胖和供熱之間存在一定關(guān)系,由此他們認(rèn)為能源成本的上漲會導(dǎo)致肥胖問題.因為為了節(jié)約生活費用,一些家庭在冬天關(guān)掉煤氣,而較低的溫度會讓人們食欲增加,而且低溫也消耗人們較少的能量.
解答 29---31 BCA
29.B推理判斷題.根據(jù)第二段內(nèi)容可知,研究人員本來是去調(diào)查冬天室內(nèi)溫度太高會導(dǎo)致肥胖問題,但是結(jié)果卻發(fā)現(xiàn)供熱好的家庭體重指數(shù)較低,而供熱不好的家庭體重指數(shù)較高.由此判斷,他們對調(diào)查結(jié)果會感到驚訝.故選B.
30.C細(xì)節(jié)理解題.根據(jù)倒數(shù)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.可知國家煤氣費用上漲,于是人們關(guān)掉煤氣去節(jié)約費用.由此可知,隨著能源價格的上漲,人們降低或者關(guān)掉暖氣主要是為了省錢.故選C.
31.A標(biāo)題歸納題.本文是一篇科學(xué)研究性短文,開頭提出中心 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.然后再進(jìn)行詳細(xì)介紹.由此可知,文章主要介紹了屋子保暖不好會導(dǎo)致肥胖的原因.故選A.
點評 點評:本文考察學(xué)生的理解推斷能力,抓住文章的關(guān)鍵詞,采用尋讀的方法查找細(xì)節(jié),能根據(jù)已知的結(jié)果推測導(dǎo)致結(jié)果的可能原因.
