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 Biology趣味导引Yesterday是甲壳虫乐队的巅峰之作，此曲被收录在1965年的专辑《Help！》中，并在《滚石》杂志最伟大的英文歌曲中高居百佳之首。

Yesterday是20世纪被改编、演奏、播放最多的一首歌曲。

作为一首吉他弹唱歌曲，Yesterday 编配简单而精妙，其和弦进行模式更是堪称经典。

Since then, records have fallen in track and field④ year after year⑤ as athletic performances have continually improved.If records fall, it is usually due to⑥ better equipment, training and diet, but recently, improvements have begun to slow down⑦.At the 2000 Olympics, only three runners achieved Olympic bests with no world records. Some experts predict a ceiling ⑧ for 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 records⑨，we come across⑩the issue of performance­enhancing⑪ drugs. These drugs are originally⑫ developed to help people with illnesses, but in the wrong hands, they create supreme⑬ athletes making them faster and stronger than is normal for human beings. Taking these drugs⑭ is known as “doping⑮” and although they enhance performance, they also cause serious health problems in later life for those who abuse⑯ them.①contemporary adj.当代的；同时代的②amateur adj.业余的③此处是虚拟语气句，表示与过去事实相反的假设，条件句中用had done, 主句中用would have done。

Her first customer was the mailman. By the end of that summer, she had raised nearly $1，000, enough to adopt and train two dogs and give them tochildren with cancer. Now, a little more than two years later, some groups gatherto make dog treats for Allison’ s cause.Her organization,the Stink Bug Project, named after a picture she drew in memory of the end of her treatment, is run and managed in partnership with the Morgan Adams Foundation. Stink Bug helps families adopt pets from the Trained K9 CompanionProgram, where the rescued dogs are taught commands. Allison’s mother,Dianna Litvak, who helps run Stink Bug, hopes to extend the pet- adoption program statewide and continue donating some of the money to help fund children’s cancer research.“ Allison has figured out how to help — in a way that no one else has，” Litvak says.“We involve her younger sister,Emily, her friends, the adopting families,and some others. It took the love of a little girl to wrap all that together intoone amazing package.”Go to to donate or to buy Allison’ s dog biscuits.【解题导语】小女孩 Allison Winn患脑瘤后在自己的宠物狗的帮助下顺利痊愈了。

Opinions are divided.Some believe that human cloning is a good thing. Firstly, They think if people had too much work to do , they could get their own clone to help them. That wouldn’t be cheating because it would still be themselves doing the work. As a result, they would have so much time to rest and have fun. What’s more, human cloning could also solve the problem of finding the organs for organ transplants. So that it could help people lead longer and healthier lives.However, others are against it .They think human cloning is a terrible idea, which could cause a lot of problems. First of all, it could cause family confusion. If people were cloned , how could their clone fit into their family? Remember, their clone would be exactly like them. In addition, clone could cause problem for society. If everyone decided to be cloned there would be a population of explosion.In my opinion, I ’d prefer to have human cloning . In that case, we can clone people with special talents that would be helpful for social development.People are against the human cloning and the argument Paragraph 1Writer’s opinion about the topic Paragraph 2People are for the human cloning and the argument Paragraph 3Introduction of the topic Paragraph 4Task 2：Read the passage to fill in the formpara1Para2-3Para4Task 3：find out topic sentences in each paragraph.Paragraph 1 Topic sentence________________________________________________________________1)______________________________________________________________2) _____________________________________________________________3)___________________________________________________________________ whether we choose to be treated by Chinese traditional Medicine _____________________.（人们关于是否选择使用中药治疗的看法不同）。
