语法进阶技巧定语从句的省略和引导词

语法进阶技巧定语从句的省略和引导词定语从句是英语语法中的一个重要部分,用来修饰一个名词或代词,并且在句中起到进一步说明的作用。
在定语从句中,有时可以省略一些词语或引导词,从而使句子更加简洁明了。
本文将介绍定语从句省略和引导词的进阶技巧。
定语从句的省略可以分为两种情况:省略引导词和省略关系代词。
首先,我们来看一下省略引导词的情况。
1. 当先行词是不定代词(all, any, some, none, something, anything等)时,定语从句引导词可以省略。
例句1: Is there anything (that) I can do for you?例句2: I have something (that) I want to show you.2. 当先行词是指示代词(this, that, these, those)或疑问代词(what, which, who, whom, whose, how, when, where, why)时,定语从句引导词可以省略。
例句1: The book (that) you recommended to me is very interesting.例句2: I don't know the reason (why) he left.3. 当先行词是不定代词或指示代词后面紧跟的名词是唯一的,且其功能与定语从句中的先行词在意义上是一致的时候,定语从句引导词可以省略。
例句1: I need a pen (that is) blue.例句2: She told me a story (that was) unbelievable.接下来,我们来看一下省略关系代词的情况。
1. 当关系代词在从句中作宾语时,且从句的谓语动词是及物动词时,可以将关系代词省略。
例句1: I have seen the man (whom/that) you are talking about.例句2: This is the book (which/that) I bought yesterday.2. 当关系代词在从句中作主语时,且从句的谓语动词是不及物动词时,可以将关系代词省略。
非谓语动词与状语从句的转化

非谓语动词与状语从句的转化非谓语动词与状语从句的转化状语从句是同学们在初中就掌握的内容,现将非谓语动词与状语从句之间转换的规律作一归纳,帮助大家更好地掌握非谓语动词。
一、非谓语动词与时间状语从句间的转换。
1 .当主、从句的主语一致,主、从句的谓语动作同时或L乎同时发生时,且从句中谓语动词是主动语态,可用现在分词的一般式转换。
如:When they heard the news,they jumped with joy.Hearing the news,they jumped with joy.当他们听到这则消息时,高兴得跳了起来。
2 .当主、从句的主语一致,从句中的动作发生在主句的动作之前或从句中谓语动词是完成时,可用现在分词的完成式转换。
如:After he(had)returned home,he began to work.Having returned home,he began to work.回到家以后,他开始工作。
3 .当主、从句主语一致时,由after,before,since,as soon as等引导的从句可分别用after/before/since/on加动名词短语转换。
如:Since I saw you last,I have been ill.Since seeing you last,I have been ill.自从我上次见你后,就一直在生病。
As soon as he heard this,he couldn’t help crying.On hearing this,he couldn’t help crying.他一听到这事,不禁哭了起来。
4 .当主、从句主语一致时,以when,while引导的从句,也可用when /while加现在分词短语转换。
如While we were walking along the river, we heard someone shouting.While walking along the river,we heard someone shouting当我们正沿着河走时,我们听到有人喊叫。

省略和倒装语法解释

多变的省略句掌握好省略句,应注意以下几条:1.感官动词或使役动词(如:notice, hear, let, make)等后接不定式作宾补时省略to,被动时to不能省略。
2.在prefer to do rather than…, cannot help but…do, nothing …but等句型中常省略to。
3.为避免重复,作某些动词(hope, want)等宾语或(tell, order, ask)的宾补时,省略不定式短语,只保留to.4.应注意状语从句、定语从句中的省略。
5.注意not ,so ,neither, nor的“替代性”省略。
6.状语从句中,如果谓语含动词be,主语又与主句主语一致或主语是it,从句中主语和be一齐省略。
7.常见的省略形式:(1)If (it is)possible[如果可能的话];(2)If (it is) necessary[如果必要的话];(3)If any: 例: Correct the mistakes in the passage if (there is) any (mistakes)比较:Do you have anything to say? (不知道对方是否有话要说,) Do you have something to say?(认为对方有话要说.)一、替代省略1. 用it, one, that,ones, those替代句子中重复出现的名词、代词或句子。
one是指代同名称的另一样东西(同类异物),代替前面句子中重复出现的可数名词;that替代特指可数或不可数名词,后面常跟有in或of短语作后置定语;it指代同名称的同样事物(同类同物)。
例:One took a taxi, and the other walked home. I haven’t a book, can you lend me one?2."So / Nor(Neither)+谓语+主语"这种句型是用来替代前面提到的情况,表明它也适用于后者。

①宾语从句是陈述句,引导词用that,在口语中that可以省略。如: We believe(that)he is honest.我们相信他是诚实的。 ②如果宾语从句由一般疑问句转换而来,其引导词用if或whether。一 般情况下,二者可以通用,但从句中有or not或从句充当介词的宾语时, 只能用whether。如: I don't know if/whether she will come here.我不知道她是否将来这儿。 Sorry,I don't know whether he will come or not.对不起,我不知道他是 否会来。 ③宾语从句是特殊疑问句时,引导词就是特殊疑问词。如:
