14、 qualified for the job.Where did you get the idea that the class would be cancelled ?1 .定语从句定语从句分为限定性定语从句和非限定性定语从句。限定性定语从句是句子不可缺少的一局部,没有它,句子不能成立,或意思不清楚,不说明问题。非限定性定语从句只对其修饰的局部作进一步的说明,没有它句子其他局部仍然可以成立。非限 定性定语从句常用逗号与前面的局部隔开。1)修饰人的定语从句who主语/宾语(口语中,可省略),that主语/宾语(可省略,前面不能有介词),whom宾语 (前面没有介词时可省略),whose定语Do

17、hich/that was lost has been found.This is the question about which weve had so much discussion.This is the question (that/which) weve had so much discussion about.The novel (that/which) he recommended is worth reading, (be worth doing ;值得做某事)当定语从句修饰的词是不定代词,如anybody,nobody,nothing等,或是有only,very,形容词最高

19、间的用when,相当于相当于“介词+ which”,在句中做状语。修饰地点的用where,相当于相当于“介词+which” ,在句中做状语。修饰原因的一般情况下跟的都是reason,用why关联词引导定语从句。He came last night when I was going to bed.I know of a place where we can have lunch.Shes going home where she can rest.Do you know the reason why I left early ?Theres no reason why he should do

22、物并做宾语,前面又有介词,只能用which.但是如果定语从句修饰的是 不定代词,或是0nM very以及形容词最高级,只能用that,在非限定性定语从句中修饰物只能用 which,修饰人只能用who.如果非限定性定语从句修饰整个句子,关联词只能用which。as也可以弓| 导定语从句,多和such连用。如:Boy as he was,he was chosen king.He was in such a fury as I have never seen.Lets discuss only such questions as concerneachof us.2 .状语从句:状语从句可以用来表
23、示时间、地点、条件、原因、目的、结果、行为方式、比拟、让步1)时间状语从句:常用的关联词有 when,whenever,before,after,while,as,once (一旦)until, (ever) since,as soon as等。时间和条件状语从句中表示将来的情况通常用一般现在时。2)地点状语从句:关联词有where和wherever.如:Sit down wherever you like.Put it where you found it.3)条件状语从句:关联词有if,unless,as/so long as (只要),in case (万一)等。如:As/So long

26、于主句之前。Because从句还可以用于强调结构, 如 It was because I wanted to see my mother that I went to Beijing last month. (It wasthat/ It is - that)b.as语气较弱,较口语化,所表的原因比拟明显,或是的事实,所以不用强调。As从句之 前不可用强调句和not,也不可用于强调结构。As从句多置于主句之前。c.since的语气也比拟弱,常表示对方的事实,往往相当于汉语的“既然”。它和as 一样, 其前也不可用强调词和not,也不可用强调结构。d.for和上述三个附属连词不同,它是一个等立连
27、词,比拟文气。它有时可用来作附加说明,Wemust get rid of carelessness,for it。代en leads to errors.我们一定要克服粗枝大叶的毛病,因为这常导致 错误。5)目的状语从句:关联词有so thatjn order that,for fear that (以免),incase (以免)等。Speak clearly so that they may understand you.He spoke slowly in order that everyone should understand.Ive got the key in case we wa

30、ung as she is,she is already familiar with most of the stories.(be familiar with 对熟悉;be similar to 和相似)Old as I am,I can still climb the mountain.9)比拟状语从句:关联词主要有than和as (像一样)。复合句局部除了应注意根据句子意思的需要选择恰当的关联词外,还应注意以下几点:(1)所有的从句都要用陈述句的句序。如:l.They want to knowdo to help us.A. what can they B. what they canC
31、. how they can D. how can they (答案 B)2 .Excuse me,sir.

33、句中作主语或宾语,有其具体的含义。that可以引导主语、宾语、表语、同位语、定语从句,在前四种从句中that没有任何具体的含 义,也不充当从句的任何成分,所以当从句意义和结构完整时,关联词往往选择that.1 .we will do next is still under discussion.A. That B. When C. Where D. What (答案 D)2 .He found at lasthe had been looking for.A. that B. what C. where D. which (答案 B)3 .He was overcome by the fear

Both B and C一、强调句(参见it的用法)强调句型由“It is (was) +被强调的成份(主语、宾语、状语)+ that”构成,当被强调的主语 表示人时,that可以用who替代,谓语在人称和数上应与主语保持一致。It ishe who speaks English fluently.It was no
38、t until midnight that he went to sleep last night.二、倒装句句子在以下场合往往用倒装的句序:1 .以here,there开头的句子。Here comes the bus.2 .以so,nor,neither引导的倒装句。如果前一个句子是肯定句,后边用so来引导倒装,这种句子是局部倒转:助动词+主语+正常语序。 如果前一个句子是否认句,后边用nor或neither引导,结构同so。倒装句在时态上应与前面的句子 保持一致,助动词的单复数应与主语保持一致。If you can do it,so canl.I like watch football m
