Unit 21 Human Biology Warm up

SectionⅠ Warm up & Lesson 1—ComprehendingA 卷Ⅰ 阅读理解AWhat would it take to persuade you to exercise? A desire to loseweight or improve your figure? To keep you away from diseases? Tolive to a healthy old age? You’d think any of t hose reasons wouldbe enough to get Americans exercising.Yet a vast majority ofAmericans have thus far failed to swallow__the__“exercise __pill ”．Nowa research by psychologists strongly suggests it’ s time to think of current well - being( 幸福 )and happiness as motivators for exercise instead of future health, weight loss and body image.Dr. Segar, one of the researchers, believes that immediate rewards are moremotivating than distant ones.“People who say they exercise for the quality of life exercise more over the course of a year than those who say they value exercise forits health benefits.” He said.Other studies have shown that what keeps people moving depends on age, sex and life circumstances. For those of college age, physical attractiveness typicallyheads the list of reasons to begin exercising,although what keeps them going seems to be the stress relief that a regular exercise program provides. The elderly, onthe other hand, may get started because of health concerns. But often what keepsthem exercising are the friendships and sense of community that may otherwise bemissing from their lives.Improving daily well - being is the most influential factor for the women. Men indicate they are motivated by more distant health benefits,but this may be because men feel less comfortable discussing their mental health needs.“ Exercise should be encouraged but the emphasis on weight loss, disease prevention and healthy aging should be reduced.” Dr. Segar concluded.“Exercise can make people feel more energetic, less stressed and, yes, happier.”【解题导语】一项研究表示，为了此刻的幸福感而锻炼的人比为减肥、保持健康而锻炼的人更能踊跃地坚持锻炼。

Unit 21 Human BiologySection_ⅠWarmup & Lesson 1 —Prereading[原文呈现]100 metres in 8 seconds?Many contemporary①amateur athletes would have broken world records if they had taken part in② the first Olympic Games. Since then, records have fallen in track and field③ year after year④ as athletic performances have continually improved.If records fall, it is usually due to better equipment, training and diet, but recently, improvements have begun to slow down⑤. At the 2000 Olympics, only three runners achieved Olympic bests⑥with no worldrecords. Some experts predict a ceiling⑦for many events, such as 9.5 seconds for the 100 metres — Maurice Greene's current record is 9.79 seconds.However, past predictions have nearly always been proved wrong.When we talk about breaking records⑧，we come across the issue of performanceenhancing⑨ drugs. These drugs are originally developed to help people with illnesses⑩， but in the wrong hands⑪， they create supreme⑫ athletes making them faster and stronger than is normal for human beings. Taking these drugs⑬ is known as “doping⑭” and although they enhance performance, they also cause serious health problems⑮ in later life for those who abuse⑯ them.[读文清障]①contemporary adj.当代的，同时代的②这是一句表示与过去事实相反的虚拟语气。
