Sleep might be one answer to the problem. A new study has found that elementary school students who slept too little were more likely to gain pounds. In the United States today, some 9 million children over the age of 6 are obese(too fat). Past studies have shown a link between sleeping less and weighing more，but scientists have had a tough time determining“Which came first，the chicken or the egg？” says Julie C. Lumeng of the University of Michigan in Ann Arbor. In other words，it hasnt been clear whether kids who weigh too much have trouble sleeping, or whether sleeping less leads to weight gain. Both scenarios(情况)seemed equally possible. To get a better idea of which causes which, Lumeng and his colleagues interviewed the parents of 785 third graders from around the United States. The parents answered questions about how well their kids slept that year. Three years later, the parents answered the same questions. By sixth grade,18 percent of kids involved in the study were obese. The scientists found no relationship between weight and the students race or gender. It also didnt matter how strict their parents were. Obesity struck all of these groups equally. Instead，sleep seemed to be the key factor. Over the 3 years of the study, the children averaged a healthy 9. 5 hours of sleep a night. Some kids, however，slept a lot moreor lessthan others. For the sixth graders, every hour of sleep above the 9. 5hour average was linked to a 20 percent lower risk of being obese. Sleep appeared doubly important for the third graders. Every extra hour of sleep they got was linked to a 40 percent drop in obesity by third grade. “I expected wed find that this(sleep link with obesity) was just a_bunch_of_bunk，”says Lumeng，a pediatrician. But their findings were convincing. No matter how her team looked at the link，“we couldnt make it go away. ”1. According to the research， _. A. 9 million people in America have a weight problemB. not enough sleep contributes to a gain in weightC. sixth graders need more sleep than third gradersD. lack of sleep has become the most deadly killer解析：选B。考查细节理解。本文阐述了睡眠与青少年肥胖之间的关系。第二段说，一项新研究发现，睡眠太少的小学生更容易发胖，美国有900万6岁以上的孩子患肥胖症。从文章的叙述判断选B。2. The statement “Which came first，the chicken or the egg？” suggests that _. A. scientists are sure about the causes of childrens obesityB. its easy to decide the cause and effect of this problemC. scientists are still confused about the cause and effect of the problemD. youll develop obesity if you eat chicken and eggs解析：选C。考查推理判断。第三段画线句子后面又说“换句话说，究竟是发胖的孩子有睡眠问题，还是睡眠减少导致了体重的增加，这还不清楚。”也就是说，发胖与睡眠减少这两者哪个是原因，哪个是结果，科学家们也还不知道。3. Recent studies show that a childs weight is influenced by the _. A. amount of sleep B. parents attitude to himC. race or gender D. performance in school解析：选A。考查推理判断。第三段说，以往的研究表明睡眠不足与发胖有联系，但科学家不知道哪个是原因，哪个是结果；第五段开头提到研究的结论：睡眠似乎是主要因素。也就是说该研究表明，孩子的体重受睡眠时间长短的影响。4. The underlined part in the last paragraph most probably means something _. A. acceptableB. understandableC. reliable D. unreasonable解析：选D。考查词义猜测。后文说“但他们的研究结论却很有说服力。”由此可推知，画线部分的含义应该是D；他们本来希望这种说法是错误的，可是研究结论却让人不得不相信睡眠和肥胖有关。B(2010年黄冈中学期中测试)Doomed beauties such as Cleopata and Manilyn Monroe were far from alone in their misery. Very attractive people tend to form partnerships that are less stable and satisfying than those enjoyed by plain_Janes . According to the research by Dr John Blaine of the University of Southern California, relationships between people whose professions largely depend on their appearance, such as models or actors, tend to end much faster than those between lawyers, doctors and students. Blaine said the beautiful felt different from children. They are treated as special, which may create both arrogance (傲慢)and insecurity. All too often, beauty can be used as an alternative to education. Often they are pushed out of their class or town, told to go off and make their fortune in Hollywood or London and, when the majority fail, they have few talents to make a living. Blaine added that beautiful people score poorly on the “big five”the key factors American experts consider when helping distressed couples. These are neuroticism(神经过敏)，including anger and anxiety; extroversion(性格外向)；openness to new experiences; agreeableness; conscientiousness, and sticking by agreements they have made. Attractive people often see no reason to try to change until their looks start to fade. Krista Sutherlanf, of the University of California Los Angeles, said partnerships that appeared to be perfect from the outside, such as the former “dream teams” of Nicole Kidman and Tom Cruise or Hugh Grant and Elizabeth Hurley, where backgrounds and aspirations(抱负) are often shared ，did not necessarily lead to happiness. 【解题导语】本文为议论文，作者论证了这样一个观点：美女并不幸福。5. What can we infer from the first sentence of the passage?A. Beautiful women always felt lonely. B. Beautiful women were always alone. C. Many beautiful women didnt end up with a happy life. D. Beautiful women always lived a happy life. 解析：选C。考查推理判断。第一段说漂亮的人，其partnership 往往不如普通人的稳定和让人满意，由此判断，文章开头说“克莱奥帕特拉和玛丽莲梦露等美女的悲惨命运绝非个例”意在表明“很多美女的生活都不幸福”。6. The underlined phrase “plain Janes” in the passage refers to“ _”. A. ordinarylooking women B. women called JaneC. common people D. attractive women解析：选A。考查词义猜测题。从语境看，画线部分的plain Janes 指与前面提到的美女相对的、相貌平常的女性，因此选A。7. We can infer from the passage that _. A. Hugh Grant and Elizabeth Hurley were a coupleB. Nicole Kidman and Tom Cruise were very satisfied with their lifeC. when they fail in Hollywood, the beautiful have little trouble in making a livingD. the marriage of the beautiful often lasts long解析：选A。考查推理判断。最后一段说，外界看上去很完美的关系，比如未必最终有幸福的结局。再结合上文论述可判断Hugh Grant和Elizabeth Hurley是夫妻关系，故选A，其他选项都与文章内容不符。8. Which of the following is the best title?A. Five key factors affecting the partnershipB. Beauties are doomed to fail in loveC. Beautiful or common?D. The beauties are different解析：选B。考查主旨大意。文章主要论述了美女命运多舛的观点，并分析了其中的原因，故B项最适合为本文标题。基础巩固练习.单词拼写1Taking regular exercise and having a healthy _(饮食)are good for your health.答案：diet2We aim to offer good service to all our _(顾客)答案：customers3The water in some western parts is so _(有限的)that people only get three cups of water every day.答案：limited4You should _(权衡)the advantages against the disadvantages before you give up your present job.答案：balance5As is known，one of the many _(好处)of adventure travel is teaching the children how to cope with the unexpected.答案：benefits6She usually _(结合)creative imagination with intelligence to create some wonders.答案：combines.易错模块1 _two exams to worry about，I have to work really hard this weekend.AWith BBesidesCAs for DBecause of解析：选A。前句说明主语I在本周末必须努力学习的原因，相当于Because I have two exams to worry about，故可用“with复合宾语”结构。besides“还有”，其后接名词、代词作宾语；as for“关于，就而言”；because of“因为”。它们都不能与句子结构搭配。2John received an invitation to dinner，and with his work _，he gladly accepted it.Afinished BfinishingChaving finished Dwas finished解析：选A。本题考查with的复合结构，表原因，“由于工作完成了，John愉快地接受了邀请”。用过去分词finished表被动。3I couldnt do my homework with all those noise _.Agoing on Bgoes onCwent on Dto go on解析：选A。本题考查“with宾语补语”结构作伴随状语。空格处为补语成分，故排除B、C选项。虽然A、D两项都可以作补语，但两者所表示的时间不同，A项中的going on表示正在进行，而D项中to go on表示将来的动作，又因为是作伴随状语，故A项正确。4(2008年高考福建卷)You have no idea how she finished the relay race _her foot wounded so much.Afor BwhenCwith Dwhile解析：选C。句意：你根本就无法体会，在脚伤得那么厉害的情况下她是怎样完成接力比赛的。这里是一个withn./pron.done/adj.的复合结构。要注意her foot wounded so much不是一个完整句子，所以不能用连词when，while，for引导。5(2008年高考上海卷)If theres a lot of work _，Im happy to just keep on until it is finished.Ato do Bto be doingCdone Ddoing解析：选A。句意：如果有很多工作要做的话，我会很高兴能留下来直到工作结束。to do可用来作a lot of work的定语，表将来。.情景交际1(2009年高考福建卷)Bruce，I really appreciate your handwriting. _.AI practise every dayBThank you very muchCNo，I dont think soDWell，its not good enough解析：选B。句意：布鲁斯，我真的很欣赏你的书法。非常感谢。根据英语习惯，如果对方表扬你，你应该表示谢意。故答案为B项。A、C、D三项不符合英语表达习惯。2.(2009年高考福建卷)Your mum is very kind.Yeah. My mum is pretty considerate，you know what_，she always arranges everything around me.Ashe means Byou meanCI mean Dwe mean解析：选C。句意：你妈妈真好。是的。我妈妈对人体贴入微。我想你明白我的意思她总是把我身边所有的事情安排得很妥当。英语中，当说话者认为对方明白自己时，可以说“You know what I mean.”3(2009年高考浙江卷)Hey, you havent been acting like yourself.Everything OK? _.AIm fine，thanks BSure，it isCThats good DIts OK解析：选A。句意：嘿！你今天表现很反常，没事吧？没事，谢谢。4(2009年高考宁夏海南，全国卷)It looks heavy. Can I give you a hand? _.ANo，thanks BYes，my pleasureCNo，never mind DYes，I do解析：选A。句意：它看起来很重。需要我帮忙吗？不用，谢谢了。“Can I give you a hand？”常用来表示提供帮助，回答时，应从礼貌出发，在拒绝的同时还应对对方的好意表示感谢，因此选A。当对方为你的帮忙表示感谢时，你需回答My pleasure(别客气)，而B项my pleasure前又含Yes，没有这种形式；C项用来回答别人道歉或安慰别人；D项用于回答喜不喜欢，做不做某事。如：Do you like swimming？Yes，I do.语法专练本单元语法情态动词()1Although this _sound like a simple task，great care is needed.Amust BmayCshall Dshould解析：选B。考查情态动词。句意：虽然这也许听起来是一项很简单的任务，但是需要非常小心。前半句中的although引导让步状语从句，由此可判断B项正确。2What do you think we can do for our aged parents?You _do anything except to be with them and be yourself.Adont have to Boughtnt toCmustnt Dcant解析：选A。本题考查情态动词的常见用法。句意：你认为我们可以为年迈的父母做些什么事呢？你不必做任何事情，只要能真心地陪伴他们(他们就很满足了)。dont have toneednt 不必；oughtnt to不应该；mustnt不可以，禁止；cant不能。3Guess what！I have got A for my term paper.Great！You _read widely and put a lot of work into it.Amust BshouldCmust have Dshould have解析：选C。句意：猜猜有什么好消息！我的学期论文得了A。真棒！你一定是博览群书并在此文上投入了很大精力。情态动词的用法是历年高考考点，从对话中可以看出此处应该是对过去动作的推测，should或must加动词原形表示对现在或将来的推测，应被排除；should have done(过去本应该做而未做某事)表虚拟或吃惊语气，与语境不符，也被排除；must have done表示对过去发生事情的肯定推测，符合题意，故选C。4(2010年山西大同学情调研)I think Ill give Bob a ring.You _.You havent been in touch with him for a long time.Ashould BwillCmay Dhave to解析：选A。考查情态动词。答语的后一句中提到“你很久没有与他联系了”，由此可知对方认为说话人“应该”给Bob打一个电话。5Listen！Someone is knocking at the door.It _be Mary；she has just left for Guangzhou.Amustnt BcantCneednt Dmay not 解析：选B。考查情态动词。由she has just left for Guangzhou可知，此处表示“不可能是Mary”，只能用cant。must 表示推测，通常用于肯定句，意为“一定，准是”；neednt表示“不需要，没有必要”；may not表示推测，意为“或许不是”。111
