(二)where的用法 在从句中作地点状语。常可用in which，at which，on which等代替。 Can you tell me the office where he works? ＝Can you tell me the office in which he works? 你能告诉我他上班的办公室吗？ [对点集训2] 用适当的关系副词填空 ①Last year my parents went to the farm _____ they worked 30 years ago again. ②The boss of the company is trying to create an easy atmosphere _____ his employees enjoy their work. ③Students should involve themselves in community activities _____ they can gain experience for growth. (三)why的用法 why在定语从句中作原因状语，可用for which代替。 This is the reason why he went away. ＝This is the reason for which he went away. 这就是他离开的原因。 [对点集训3] 用适当的关系副词填空 ①Is this the reason ___ he refused our offer? ②The reason ___ he didn't come was that he had to look after his mother. [名师点津] 1．区别使用关系代词还是关系副词的方法是看他们在定语从句中充当的成分。关系代词充当主语、宾语、表语或定语，关系副词充当状语。 试比较下面两组句子： This is the factory that/which produces radios. This is the factory where radios are produced. 这就是那家生产收音机的工厂。 [对点集训4] 用适当的关系词填空 ①The book has helped me greatly in my daily communication，especially at work _____ a good impression is a must. ②Many countries are now setting up national parks _____ animals and plants can be protected. ③I don't know the reason ___ you were absent from the meeting，but I'm sure someone will tell me the reason __________ you haven't told me. 2．关系副词(＝介词＋关系代词) 关系副词 先行词 含义 where 表示地点的名词：抽象地点和具体地点 “(在)……地方”，相当于“介词＋which” when 表示时间的名词 “在……时候”，相当于“介词＋which” why reason “为什么”，相当于“for which” [对点集训5] 用适当的关系副词代替句中的黑体部分 ①The rain came at a time at which it was not needed.____ ②This is the computer by/on which he has stolen top secret documents._____ ③Here is the place at which the murder took place._____ ④He didn't give any reason for which I had been fired.___ (四)“介词＋关系代词”引导的定语从句 1．“介词＋关系代词”结构 定语从句中的介词有时可置于关系代词之前，形成“介词＋关系代词”结构。关系代词通常是which和whom，which指物，whom指人。 ①The school (that/which) Lucy is studying in is very famous. →The school in which Lucy is studying is very famous. 露西就读的这所学校很有名。 ②Do you know the actor (whom/that) the reporter is talking with? →Do you know the actor with whom the reporter is talking? 你认识记者正在与之交谈的那个男演员吗？ [名师点津]　 若定语从句中的短语是固定搭配，拆开便失去了原来的意义，则介词通常不能前置到关系代词之前。如look for，look after，take care of等。 This is the painting which/that he's looking for. 这就是他正在找的那幅画。(从句中的look for为固定短语，不能拆开) [对点集训6] 用“介词＋关系代词”引导的定语从句合并句子 ①Liu Yang will never forget the day. She was carried into space by spaceship on that day. →_________________________________________________________________________ ②The store was broken into last night. My sister works in the store. →______________________________________________________ ③The reason is that he was ill yesterday. He did not hand in his homework for that reason. →__________________________________________________________________ ④The English play was a great success. The students acted in it at the New Year's party. →_________________________________________________________________________ ⑤Who is the man? You shook hands with him just now. →__________________________________________________ 2．介词的确定方法 结合句意，一看先行词，二看从句的谓语动词与先行词的搭配来确定介词。 ①In this room，we saw a big table on which there were all kinds of fruits. 在这个房间里，我们看到一张上面放着各种各样的水果的大桌子。(which代指a big table，介词根据on the table 来确定) ②This is the man from whom I learned about the news./This is the man whom I learned about the news from. 我就是从这个人那儿听到那个消息的。(whom代指the man，介词根据learn...from来确定) [对点集训7] 用适当的“介词＋关系代词”填空 ①This is a picture of Lei Feng _________ we've learned a lot. ②To tell you the truth，the singer ________ you are waiting won't come tonight. ③As we all know，the age ________ children can go to school is seven. ④These are the visitors _______ the man was too rude. ⑤He built a telescope _____________ he could study the sky in his free time. 议论文写作 (对中小学生肥胖与健康的看法、建议) 一、文体特点 议论文写作，就是要表达看法，并且要有观点的支撑。 二、审题谋篇 写作结构应遵循摆出观点、理由支撑、总结三部分的要求，应该目的明确，材料准确翔实，语言简练。 三、知识储备 ★常用词汇、短语、句式 1．energetic精力充沛的；充满活力的 2．collapse 昏倒；倒塌 3．faint昏厥；快要昏厥的 4．weight-loss pills减肥药 5．slim figure(s)苗条的身材 6．healthy diets健康的饮食 7．get into shape强身健体 8．contribute to 导致 9．in general大体的；一般的 10．on the whole总的来说 11．in addition/besides/what's more/furthermore/moreover此外 12．I think/believe/feel...我想/认为/感觉 13．to be honest老实地来说 14....against/for...……支持/反对…… 15....have/has changed my mind……改变了想法 16．(don't/doesn't)believe/agree/think that... ……(不)认为/相信…… 17．We think the best way to get fit is through exercise. 我们认为保持健康最好的方法是锻炼。 18．It's very important to have good living habits. 拥有好的生活习惯是非常重要的。(it作形式主语) 19．You should do regular exercise and have enough sleep. 你应该定期锻炼和保证充足的睡眠。 20．I do a lot of exercise every day.I walk to school instead of taking a bus. 我每天做很多运动。我走路去学校而不是坐公交车。 21．We should keep ourselves happy.A happy man lives longer than a sad man. 我们应该让自己保持愉快。愉快的人活得更长久。 22．A cheerful state of mind is equally important to our health. 愉快的心情对我们的健康同等重要。 23....need to get rid of bad habits like staying up.It is an important way to keep healthy. ……应该改掉熬夜的坏习惯。这是保持健康的一个重要的方法。 24....should have breakfast every morning.It can give you enough energy to study for the whole morning. ……应该每天吃早饭，它能给我们提供足够的能量。 25．Remember to go out of the classroom to play with your classmates or do some physical exercise during the breaks. 记住：在课间的时候走出教室和同学们做一些体育锻炼。 26．It is important for you to have a healthy lifestyle and eat a balanced diet. 健康的生活方式和均衡的饮食是非常重要的。 27．To learn to look after ourselves and to keep healthy are two of the most important things. 学会照顾自己和让自己保持健康是最重要的两件事。 28....need to keep a balanced diet.Remember to have meals regularly and eat more vegetables and fruit. ……需要保持均衡饮食。记得要规律饮食，多吃一些蔬菜和水果。 29．Health is the first wealth. 健康是第一财富。 30．Where there is life，there is hope. 留得青山在，不怕没柴烧。 31．Diet cures more than doctors. 自己饮食有节，胜过上门求医。 32．An apple a day keeps the doctor away. 一天一苹果，医生远离我。 33．Early to bed and early to rise makes a man healthy，wealthy and wise. 早睡早起使人健康、富有和聪明。 肥胖已经成为危害人们健康的严重问题，中小学生的肥胖趋势更为明显。你们班对此展开了讨论。根据不同的观点，写一篇80词左右的短文。 观点 原因 支持 肥胖危害健康，应该节食、锻炼、预防肥胖，已经超重的应该采取措施减肥。 反对 中学生处于长身体的时候，减肥会影响身体发育，也会影响学习，因此应该顺其自然。 参考词汇：肥胖fatness 注意：可以适当增加细节，以使行文连贯。 [思路点拨] 一、审题定调 1．确定体裁：本文是议论文； 2．确定人称：本文的主要人称为第三人称； 3．确定时态：主要以一般现在时为主。 二、基本结构 开头：引出话题。 主体：内容要点。 结尾：总结。 [词汇热身] 1．have a bad effect on...对……有坏的影响 2．carry out a discussion展开讨论 3．be on a diet节食 4．take suitable exercise做适当的锻炼 5．have a different opinion有不同的观点 6．lose weight减肥 7．take measures to do采取措施做…… 8．be bad for对……有害 [主要句式] 1．Fatness is one of the serious problems. 2．Fatness has a bad effect on our health. 3．Some students think that fatness does harm to our health. 4．It is necessary to be on a diet and take suitable exercise to prevent it. 5．Overweight people should do something to lose weight to be healthy. 6．There is no need to change the situation.

[语篇解读]　本文介绍了一种新型的足球比赛MAN v FAT，这个比赛给肥胖的人提供了经常锻炼的机会，有助于减肥，同时还能避免他们的尴尬。 答案　Judging 1．解析　考查时态和语态。(a competition)最近(recently)被组织(organize)，该用现在完成时的被动语态，主语是单数，所以填has been organized。 答案　has been organized 2．解析　考查非谓语动词。Judging from...根据……来判断，在句中作状语，首字母大写。 答案　to get 3．解析　考查名词。这里的pound是可数名词，用复数形式。 答案　pounds 4．解析　考查非谓语动词。上文有purpose, to do 表目的，所以填to get。 答案　which 5．解析　考查代词。it指的是上一段提到的a new football competition，MAN v FAT。 答案　it 6．解析　考查定语从句。在减肥课上，大多数学员是女性。which引导定语从句，指的是前面的classes，放在介词in之后，作宾语。 答案　as 7．解析　考查形容词。这个词所在句子的意思是：我不想和比我瘦的朋友踢足球，空后的单词than是线索词，所以该用比较级thinner。 答案　thinner 8．解析　考查介词。the same as为固定搭配，意为“和……一样”。所以填as。 答案　an 9．解析　考查副词。修饰动词filled，作状语，应用副词形式，故填mainly。 答案　mainly 10．解析　考查冠词。表示泛指，一个有效的方式，因为effective以元音因素开头，所以用不定冠词an。 $$
