A desire to lose weight or improve your figure? To keep you away from diseases? To live to a healthy old age? You'd think any of those reasons would be enough to get Americans exercising. Yet a vast majority of Americans have thus far failed to swallow the “exercise pill”． Now a research by psychologists strongly suggests it's time to think of current well-being 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 more motivating 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 for its 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 typically heads 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, on the other hand, may get started because of health concerns. But often what keeps them exercising are the friendships and sense of community that may otherwise be missing 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.” 语篇解读：本文是一篇说明文。一项研究表明，为了现在的幸福感而锻炼的人比为减肥、保持健康而锻炼的人更能积极地坚持锻炼。 1．What does the underlined part in Paragraph 1 mean? A．Be free from diseases. B．Take some diet pills. C．Improve their figure. D．Keep physically active. √ 解析：词义猜测题。根据前文可知，美国人可以找到很多理由进行身体锻炼，但大多数美国人都不能做到积极锻炼，由此可知，D项与画线部分意义接近。 2．According to the passage, which of the following people may exercise more in a year? A．Jane, who decides to lose weight. B．David, who exercises for future health. C．Mary, who enjoys exercising with her son. D．Mark, who is suffering from a serious illness. √ 解析：推理判断题。根据第二段可知，研究表明，应将目前的幸福感作为锻炼的动力，而不是未来的健康、减肥和体形，故和儿子一起享受锻炼的Mary一年中会做更多的锻炼。 3．According to Paragraph 4, which group of people tends to exercise for friendship? A．Men.　　　　　　　　 B．Women. C．The elderly. D．College students. 解析：细节理解题。根据倒数第二段中的“The elderly, on the other hand ... But often what keeps them exercising are the friendships and sense of community”可知，老年人倾向于为了友谊而锻炼。 √ 4．What is the author mainly arguing in the passage? A．Immediate rewards of exercise should be emphasized. B．Distant benefits should be the motivators for exercise. C．Feeling relaxed is more important than future health. D．Men and women take exercise for different purposes. 解析：主旨大意题。纵观全文，尤其是文章的第二段和最后一段可知，本文旨在强调应将即时的回报作为锻炼的动力。 √ Ⅱ.完形填空 A Saturday morning, we noticed a handful of soft brown curly hairs on Rosie's pillow.Was she 5 about her new school life? Or unsuitable shampoo? We 6 it with another brand, but Monday morning brought twice as many curls.Sadly, by Thursday, Rosie's hair was all 7 .

Facing stares from other children, Rosie has learned Smile, Pride, Introducing herself, Raising 18 by sharing her story, Inquiring what makes them unique and Thankfulness.

But for many people, personal privacy (隐私) is very 2 (importance). In many homes, a few minutes in the bathroom is all the privacy that is available. Teenagers especially need their own personal space at home 3 they can feel relaxed and private. But, of course, not all teenagers are lucky enough to have a room 4 their own. Where space is short, they often have to share a bedroom with a brother 5 a sister. In that case, it's a good idea for them to have a special area or corner of the room to call their own. It is 6 (similar) important for young people to have somewhere to keep their personal things. This may or may not be a tidy place and it is not a good idea for parents to try and tell teenagers how 7 (organise) their space as this is likely to lead to 8 (argument). Parents can, however, make sure that there 9 (be) enough storage (存储) spaces such as shelves, cupboards and boxes. This will allow the teenagers to keep 10 (they) space tidy if they want to. 语篇解读：本文是一篇说明文。越来越多的人生活在大城市里，个人的空间和时间都开始变得越来越少。本文指出个人隐私空间的重要性，尤其是青少年需要在家里拥有自己的私人空间。 1．means　which指代逗号前的内容，作定语从句的主语，所以从句谓语动词应用第三人称单数形式。故填means。 2．important　空处位于be动词后且前有副词very修饰，应用形容词作表语，故填important。 3．where　空处引导定语从句，修饰先行词their own personal space at home，且在定语从句中作地点状语，所以应填关系副词where。 4．of　of one's own为固定搭配，意为“某人自己的”。故填of。 5．or　句意：在空间狭小的地方，他们经常不得不和兄弟或姐妹合住一间卧室。根据句意可知，此处应用连词or表示选择。故填or。 6．similarly　修饰形容词important应用副词形式。故填similarly。 7．to organise　此处为“疑问词＋to do”结构，在句中作tell的宾语，故填to organise。 8．arguments　argument意为“争论，争吵”时，是可数名词，此处应用其复数形式，故填arguments。 9．are　there be句型的主语在后面，本句主语为复数名词spaces，再结合时态可知，应用一般现在时，故填are。 10．their　作定语修饰space 应用形容词性物主代词。故填their。 本课结束 $$
