定语从句引导词的用法
定语从句引导词的用法 that 和Which 都可以指物，其用法区别： 相同点(Similarities) 1.这两个关系代词引导定语从句时，都可以指物； 2.在定语从句中都可作主语或宾语； 3.作宾语，并且前面无介词时都可省略。 The train that/which has just left is for Shanghai．刚开的那列火车是去上海的。(作主语) The book (that/which) you gave me is wonderful. 你以前给我的那本书好极了。(作宾语,可省略) 不同点(Difference) 1.以下情况常用that。 （1）当先行词是不定代词或被它们修饰时（all, something, anything, nothing, everything, none, any, some, few, little, much, many等）。 Is there anything that I can do for you有什么要我做的事吗 He answered few questions that the teacher asked．他几乎没有回答老师的那些问题。（2）当先行词被every, no, the only, the very, the right, the last, just修饰时。T hat‘s the only thing that we can do now. 目前我们只能这样了。 Those are the very words that he said. 那就是他的原话。 （3）当先行词被形容词最高级或序数词修饰时。 This is the most int eresting book that I’ve had. 这是我拥有的最有趣的书。 The first thing that should be done is to get some food．该做的第一件事是弄点吃的。 （4）当先行词是一个既指人又指物的并列词组时。 They were talking about the persons and things that they saw in the factory．（5）当关系代词在定语从句中作表语时。 China is not the country that it was．中国已经不是过去的中国了。 （6）当在以which开头的疑问句中时。 Which is the car that was made in Beijing 哪辆是在北京制造的车 2.以下情况常用which。
(完整word版)时间状语从句地引导词
时间状语从句的引导词 when, before, after, as, while, till/until, since，whenever 时间状语从句的用法 时间状语从句的引导词所表示的意思不尽相同，要注意把握不同的时间状语从句的引导词所表示的不同时间关系，以及它在具体句子中对应的对应时态、语态等问题。 1. when、as、while引导的时间状语从句分析： (1) when引导时间状语从句时表示“当……的时候”，when既可以指时间段也可指时间点，从句中既可用短暂性动词又可用延续性动词，且动作既可和主句的动作同时发生又可在主句的动作之前或之后发生。 注意体会如下例句： I’ll call you when I get there. 我一到那里就给你打电话。 When the wind blows, all the doors rattle. 只要风一吹，这门就吱嘎作响。
When I came home my wife was cooking dinner. 我回家时，妻子在做晚饭。 如果when引导的时间状语从句的主语与主句主语相同，而从句的谓语又是be动词时，那么从句中的主语和be 可以省略;当when引导的时间状语从句的主语与主句主语相同时，往往还可以用“when+分词”的形式替代该状语从句。例如： When (you are) in trouble, ask her for help. 当你遭遇麻烦的时候去向她求助。 When I came into the room (=When coming into the room), I found him lying there asleep. 当我进入房间的时候，我发现他躺在那儿睡着了。 (2) while引导时间状语从句时表示“当……的时候”，它强调主句的动作与从句的动作同时持续地进行，用于这一用法时while引导的时间状语从句和主句中的谓语动词必须是延续性动词，或者主句的动作发生在从句动作的进行过程中，主句中的谓语动词通常是非延续性动词，例如 Study while you study; play while you play.
where引导定语从句的用法
Where引导定语从句,先行词不一定都表 示地点 1、We will discuss a number of cases __ beginners of English fail to use the language preperly、A、which B、as C、why D、where 2、He was driving so fast as to get himself into a dangerous situation ___he is likely to lose the control over his car、 A、which B、as C、why D、where 两道题都选where ,但就是case, situation都不就是地点,如何理解？ 在“先行词不就是表示地点的名词”的前提下,如何判断就是否使用关系副词where来引导定语从句的问题就是一个高频考点。就就是说,关系副词where 所指代的先行词不只就是表示地点的名词。
用Where引导定语从句,先行词不一定都表示地点按照通常的理解,当where 引导定语从句时,它的先行词就就是表示地点的名词,但事实并不就是我们想象的那么简单。很多情况下,where所指代的先行词并不表示地点。请瞧以下几个例句: Other research, where siblings have been asked to say who their mother and father favor, suggests that mothers do tend to show a preference for their first-born son, but fathers often show great affection for their youngest daughters、 1、Remember that the best relationship is one where your love for each other is greater than your need for each other、请记住,最深的感情关系表现为彼此间的爱超过彼此间的需要。

which引导的定语从句的用法
which引导的定语从句的用法 WHICH可以引导定语从句，修饰表示事物的先行词，在定语从句中充当主语、宾语或者表语。例如：HEWASREADINGABOOK， WHICHWASABOUTWAR.他正在读一本关于战争的书。（关系代词WHICH在修饰BOOK的定语从句中充当主语。） HEWASREADINGABOOK，WHICHHEHADBOUGHTFROMLONDON.他正在读一本书，这本书是从伦敦买回来的。（关系代词WHICH在修饰BOOK的定语从句中充当宾语。） WHICH引导非限定性定语从句时有一个特殊用法，即它所引导的非限定性定语从句修饰主句中更多的部分甚至整个主句（这时被定语从句所修饰的“先行词”要作广义理解），WHICH仍在定语从句中作主语、宾语或表语。例如：HESETFREETHEBIRDSHAPPILY， WHICHWASACELEBRATIONFORHISSUCCESS.他开心地把鸟放了，这是对他成功的一种庆祝。 把非限定性定语从句“WHICHWASACELEBRATIONFORHISSUCCESS”的先行词视为主句中的“THEBIRDS”显然不符合整句的语境，被 “WHICHWASACELEBRATIONFORHISSUCCESS”所修饰的是整个主句，WHICH所引导的这类特殊的非限定性定语从句对主句所叙述的情况进行某种意义的补充说明，WHICH常可译为“这一点，这件事”。 ［考题1］ YOUCANFINDWHATEVERYOUNEEDATTHESHOPPINGCENTRE， ____ISALWAYSBUSYATTHEWEEKEND.（2006上海春） A.THAT B.WHERE C.WHAT D.WHICH ［答案］D
介词引导的定语从句 -答案
介词+关系代词引导的定语从句 “介词+关系代词”引导的定语从句是定语从句的一种复杂形式，这类定语从句的关系代词主要有which ,whom , whose , 它们既可以引导限定性定语从句，也可以引导非限定性定语从句。关系代词前该选用什么样的介词，要根据不同的语境、习语、惯用法等来决定。一．介词选择的主要标准 1.介词与定语从句的先行词是一种习惯性搭配 Human facial expressions differ from those animals in the degree to which they can be controlled on purpose.人类的面部表情和动物的面部表情就可控制的程度来说是不一样的。( to a degree ) The English play in which my students acted at the New Year’s party was a great success.那场在新年晚会上我学生参加表演的英语剧很成功。( in the play ) The schools themselves admit that not all children will be successful in the jobs for which they are being trained.学校本身承认，并不是所有的孩子都能在他们所接受的培训的职业成功。( be trained for the job ) 2.介词与定语从句中的动词是一种习惯性搭配 Who is the man with whom our teacher is shaking hands? 我们的老师与之握手的那个男士是谁？( shake hands with sb. ) Last month , part of Southeast Asia was struck by floods , from whose effects the people are still suffering. 上个月，东南亚的部分地区发生洪水，人们还在遭受着洪水所带来的影响。(suffer from sth. ) 3.介词与定语从句中的形容词构成一种习惯性的搭配 Ours is a beautiful country , of which we are greatly proud . 我们的国家是一个美丽的国家，我们为之感到很自豪。( be proud of ) The woman to whom Spielberg is married is an actress. 同斯皮尔伯格结婚的女人是一位演员。( be married to ) The woman to whom he was engaged was a doctor. 他与之订婚的那个女士是位医生。(be engaged to ) 4.有时关系代词前用什么介词，要根据句子的意思来决定，此时不但要注意其前的搭配，也要注意其后的搭配 I was a woman running toward me in the dark. Before I could recognize who she was, she had run back in the dark.Before I could recognize who she was , she had ran back in the direction from which she had come.看见一位妇女在黑暗中像我走来，我还没来得及认清她是谁，她已经从她来的方向跑回去了。（如果仅注意先行词，很容易受习惯心里的影响而使用in this direction 的搭配，但考虑到语境后的come ，则应该使用from。） He was educated at the local high school, after which he went on to Beijing University. 他在当地一所高中上学，之后他上了北京大学。（after which 的意思就是“在当地一所高中接受完教育之后”）。 In the office I never seem to have time until after 5:30 pm. by which time many have got home.在 办公室我好像总是没时间，只有等到下午五点半，而那个时候大家都已经回家了。（此句不能受at 5:30 pm 的通常表达的影响而选用介词at, 而应该依据整个句子的语意来确定介词。）5.表示“所有格”或“整体与部分关系”时，用介词of The journey around the world took the old sailor nine months, of which the sailing time was 226 days.这次环球旅行老水手用了9个月，其中航行的时间是226天。 The factory produces half a million pairs of shoes every year, 80% of which are sold abroad. 这个工厂每年生产50万双鞋，其中的（指50万双鞋）80%销往海外。 I was told that there were about 50 foreign students studying Chinese in the school, most of whom

Who is the old man that speak to you just now ? 二、修饰物时只用which不用that的情况 1，引导非限制性定语从句时。例如： Bamboo is hollow, which makes it light.竹子是空心的，这使得他很轻。2，当关系词前有介词时。例如： This is the room in which Chairman Mao once lived.这就是毛主席曾经住过的地方。 3，在一个句子中有两个定语从句，其中一个定语从句的关系代词用了that, 另一个宜用which。例如： Let me show you the novel that I borrowed from the library which was newly open to us.我来给你看我从新开的图书馆里借来的那本小说。 4、当关系代词后面有插入语时。例如： Here is the English grammar which, as I have told you, will help improve your English.这就是我跟你说过的会有助于你学好英语的那本英语语法书。5、先行词为that时。例如： The clock is that which can tell us the time.钟是报时的装置。 三、修饰人时只用who不用that的情况 1、先行词为one, ones, anyone, those指代人时。如： The person I want to learn from is one who studies hard and works well.我最羡慕的是学习勤奋，工作出色的人。
