1 主从复合句主句是主体，从句只是句子的一个成分，换言之，将句子（除谓语外）的各个成分扩展开来就成了从句。关联词分五类：疑问代词：who（whom/whose），which,what,关系代词：who（whom/whose），which,that,疑问副词：when,where,why,how 关系副词：when,where,why 从属连词：that(无词义)，whether,if,although,after because,before,when,since，as soon as,as long as 只有从属连词没有句子功用，即不担任句子成分。从句分为五类：主语从句宾语从句表语从句前三项都是名词性从句，句中作用如同名词。一般都不用逗号，所用关联词相同：1,连词 that/whether/if 2,疑问代词 who/what/which 3,疑问副词 when/where/how/why（引导间接疑问句）定语从句状语从句记住一个句子学会一种句法现象。一主语从句subject clause，也可分为 三种：that 引导的主从/由连接代副词引导的主从/what 和whoever等引导的主从。1 由 that 引导的主从，用得最多。(that 后面是主语)“That she became an artist may have been due to her father s influence.”她成为画家可能是受其父亲的影响。上面句子看着别扭陌生，换成it 引导的句子就熟悉了，因为一般除强调外都后置而由it 代替，有五种形式：（1）It+be+adj+that、It is natural that they should have different views.（2）It+be+noun+that、It s a wonder that you are still alive.（3）It+verb(+object(宾语)or adverbial(副词)+that、It seems that you re right.It struck me that we ought to make a new plan.我忽然想起我们应该制订一个新计划。It

couldn t be that they were interested in him.不，不，他们不可能对他有兴趣。口语中 that可以省略：It was clear(that)his words pleased her.显然他的话使她高兴。2 由连接代/副词引导的主从When he ll be backdepends much on the weather.Who is to be sent there hasn t been decided.It s clear enough what he meant.两种结构都能用，但是it 结构更多，有四种形式。2 it+be+adj+clause It was not clear to mewhy he behaved like tha t.我不太清楚他为什么会这样做。it+be+noun+clause It s a puzzle how life began.生命如何开始是一个谜it+verb(+object or adverbial)+clause It doesn t matter much where I live.我住在哪里都没多大关系。it+be verb-ed+clause It is not yet settled whether I am going to American.3 由

meant.这不是我的意思。The question is who s responsible for what has happened.问题是发生了这事该谁负责。Times aren t what they were.时代不同了。That s what I am here for.这就是我来这里的目的。(四定语从句 attributive clause 没看！1 定从的关联词有二：关系代词（在从句中作主/宾/定）who（whom/whose）,which,that 和关系副词（在从句中作状语）when,where,why等。例如：Girl who works in restaurant is called waitress.This is Johnson,whose wife work at a department store.2 Which 和 that 的区别：关系代词 which 指物，做主语和宾语。限制性定从中作宾语时可省略。关系代词 that,指物也指人，做主语和宾语，指物时与which 相同。There are the things that（which）you need.这些就是你要的东西。A dictionary is a book,which gives the meaning of words.词典是解释词义的书。Who is the person that is working at a computer over there.在计算机上干活的那个人是谁？3 在下列情形下，只能用that:（1）先行词是 all/everything/nothing/something（有时例外用 which）/anything/little 等不定代词时。Is there anything(that)I can do for you in town?有什么事我可以在城里代你办吗？That s all(that)I know.我知道的就是这些。（2）先行词为序数词所修饰时。The first thing(that)I should do is to work out a plan.我该做的第一件事是订个计划。（3）先行词为形容词最高级所修饰时。This is one of the most exciting football games(that)I have ever seen.这是我看过的足球赛中最激烈的一场。4 限制性定从和非限制性定从：意义上可缺否，形式上有无逗号。（1）that 引导的定从大多是限制性的。注意：非限制性定从不能使用that 和关系副词 why,也不能省略任何关系副词，这类从句主要出现在书面语中。如：This is the best film that I have ever seen.Last night I saw a very good film,which was about the Anti-Japanese War.“昨晚我看了一部很棒的电影，是关于抗日战争的”只是补充说明，翻译时多译成并列句：Sunday is a holiday,when people do not go to work.礼拜天是假日，这一天人们不上班。（2）非限制性定从中which/whom 常可以跟 of 或其他介词连用。Mr.Smith,for whom I was working,was very generous about overtime payments.史密斯先生是我的老板，她付超时工资很大方。The buses,most of which were already full,were surrounded by an angry crowd.公共汽车大多都已满载，周围是一大群愤怒的人。My kids,both of whom study abroad,ring me up,saying Hi,every week.我的俩孩子都在国外读书，每周给我打来电话问安。文档编码:CL2L10V10I6B2 HP3A2D9G6U8 ZC8W8C6W2P6文档编码:CL2L10V10I6B2

HP3A2D9G6U8 ZC8W8C6W2P6文档编码:CL2L10V10I6B2 HP3A2D9G6U8 ZC8W8C6W2P64（3）在限制性定从中，当关系代词在从句中作宾语时，大多可省略，特别是在被修饰的词为all/everything 等词时。如：That s the only thing we can do now.这是我们现在唯一能做的事。All you have to do is to fill out this form.你只需要填这张表就行了。关系副词 when时间状语,where地点状语，why 原因状语。Do you remember the time when he fell off his bicycle?你记得他从自行车上摔下来的时间吗？The book is on the table where you left it.那书在你拉在那儿的桌子上。I don t know the reason why he was so rude.我不知道他为什么这么无礼。（4）注意，有些时间定从并不由when 引导，特别在某些句型中。Every time the telephone rings,he gets nervous.电话铃一响他就紧张。Come any time you like.你随便什么时候来都行。She made me feel at home the moment I arrived.我一到达她就使我感到无拘无束。（5）在 way 后面的定从，不跟关系代词或副词。That s the way I look at it.这就是我对这事的看法。I did not like the way he eyed me.我不喜欢他瞪着我瞧的样子。（6）关系代词 which 的先行词，有时是整个主句或部分意思，这时which 的意思相当于 and this。They rely on themselves,which is much better.他们依靠自己，这样好得多。He drank beer,which made him fat.他喝啤酒，这使他发胖。（7）Which 有时在定从中作定语I called him by the wrong name,for which mistake I should apologize.我把他的名字叫错了，对此错误我应道歉。（8）定语从句被分词短语代替由 who 或 that(which)作主语的限制性定从，有时可以被分词短语代替，更为简练。There are many students who are studying English in this school.-There are many students studying English in this school.（9）一些其他定语从句as主要和 such 连用,也可用作关代引导定从：Such money as he earned was spent on spirits烈性酒 and tobacco.他挣的那点钱都花在烟酒上了。There was a look of fear in his eyes,such as people have when they are suddenly awakened.他眼中透出一种人们突然被叫醒时露出的惊恐情绪。as可以单独引导定从He was a foreigner,as I knew from his accent.我可以从他的口音中听出他是个外国人。You are a teacher,as is clear from your manner.你是位教师，这从你的举止上可以看得很清楚。As was expected,he performed the task with success.正像预料的，他成功地完成了任务。（10）But 也可用作关系代词来引导定从，意思接近于that(who)not。这种用法已显陈旧。There is no tree but bears some fruit.没有不结果的树There are very few but admire his talents.很少有人不佩服他的才华。Surely there isn t a teacher but faces this problem.可以肯定，凡是老师都面临着这个问题。（11）Whereby,wherein,whereupon 也可以引导定从They ve set a plan whereby(=by which)you can spread cost over a period.他们定出了一个办法，照此你可以分期付款。文档编码:CL2L10V10I6B2 HP3A2D9G6U8 ZC8W8C6W2P6文档编码:CL2L10V10I6B2 HP3A2D9G6U8 ZC8W8C6W2P6文档编码:CL2L10V10I6B2 HP3A2D9G6U8 ZC8W8C6W2P6文档编码:CL2L10V10I6B2 HP3A2D9G6U8

在、期间/after/before/as soon as/since/till(until)/whenever 等等All things are difficult before they are easy.凡事总是先难后易。On and on he went,till/until he reached the outskirts of the wood.他走啊走啊，直到走到树林边。Once you ve finished,go to bed.你一干完就去睡觉。Come and talk to me whenever you feel lonely.感到寂寞时就来和我说说话。注意 when/as/while 的区别：when 从句动作可以和主句动作同时发生，也可以先于主句动作。As 和 while 都是同时。It was raining when we arrived.同时发生When I pressed the button the radio stopped.从句动作先于主句动作。She sang as she worked.同时，边、边、While you were away,two persons came to see you.同时。你不在时有两个人找你。注意 2：有些时状从句不用连词引导He came directly I called.我一叫他就来了。He had

Reason：because/for/since既然/now that既然/as由于例如：Maize is also called Indian corn because it was first grown by the American Indians.因为玉米是美洲印第安人首先种植的，所以又叫印第安玉米。（回答 why，语气最强，是全句的重心所在）As you make your bed,so you must lie on it.你是自作自受。-表示较明显原因，常放在主句前面Since I m here today,I saw everything.今天我既然在这，我一切都看见了。（跟 as相似，表示稍加分析后的原因，且多少是对方已知熟悉而不待言的原因）The days are short,for it is now December.白天短了，因为现在已经是十二月了。（跟 because相似，但 for 只能表示上文未表示的新情况，只能放在句末）Now that you have the chance，you had better avail yourself of it.既然你有了机会，你最好利用起来。文档编码:CL2L10V10I6B2 HP3A2D9G6U8
