时间状语从句知识点归纳是什么?

状语从句(Adverbial Clause)是指句子用作状语时,起副词作用的句子。状语从句可以修饰谓语、非谓语动词、定语、状语或整个句子。

状语从句根据其作用可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等从句。状语从句一般由连词(从属连词)引导,也可以由词组引起。从句位于句首或句中时通常用逗号与主句隔开,位于句尾时可以不用逗号隔开。

时态特点:

一般情况下,时间和条件状语从句的谓语动词一般用“一般现在时”表示“一般将来时”,用“现在完成时”表示“将来完成时”。

例如:1、I will call you as soon as I arrive in Beijing.我到北京就将给你打电话。

这是由as soon as引导的时间状语从句,从句中的谓语动词arrive是一般现在时,表示一般将来时,绝不可用will arrive。

2、As soon as I have finished this work, I will have gone home.我一完成这项工作,就会回家。

从句中的谓语动词用现在完成时have finished,表示将来完成时,绝不可用will have finished。

3、If he comes back, please let me know.如果他回来了,请通知我。

从句中的谓语动词用comes back,表示一般将来时,绝不可用will come back

从句通常结构:主 do sth./do sb.(条件)+ V./结果。

语法特点:

1、时间状语从句:常用引导词:when(在…时), as(当…时), while(在…期间), before(在…之前), after(在...之后), since(自从...以来) , not...until(直到…才)until/till(直到…时)等。

特殊引导词:the minute, the moment, the second, every time, the day,the instant( 瞬间,顷刻), immediately , directly(不久,立即), no sooner … than(一...就...), hardly …when(刚一...就...) , scarcely … when(刚...就.../一...就...),as soon as(一…就…)。

当用no sooner … than,hardly …when,scarcely … when作为引导词的时候,从句要部分倒装。

2、地点状语从句:常用引导词:where;特殊引导词:wherever,anywhere,everywhere。

3、原因状语从句:常用引导词:because,since,as;特殊引导词:seeing that,now that,in that,considering that,given that。

高考对状语从句的考点:

1、全面掌握状语从句的九大类别。

2、根据历年高考试题,对状语从句的考点要进行全面的归纳,在九大类别中的考查热点中,重点把握在引导时间、地点、条件、让步、比较、原因状语从句的连词运用上。

3、熟练运用出现频率较高让步状语从句和原因状语从句。

4、做好易混词的辨析如:as, when, while等,时间状语从句因为连接词容易出现在一些常用结构里也经常出现。

5、掌握状语从句中的时态、语态、语气、省略。

方式状语举例

时间状语从句知识点如下:

1、引导时间状语从句的`从属连词很多,如较基本的有before, after, when, while, as, since, till, until, as soon as 等。

2、when?从句多用一般过去时,主句的时态视情况而定。

3、when 多用一般过去时,它表示的是一个时间点.when 从句的动词大多是瞬时动词。

4、as?的用法一般用一般过去时。as 从句一般可以翻译成“一边……一边……”。

5、当从句的动作发生于主句动作之前,只能用when。

关于状语从句省略的知识

状语从句的简化 ?状语从句的省略

状语从句同时具备下列两个条件:①主句和从句的主语一致,或从句主语为it;②从句主要动词是be的某种形式。从句中的主语和be动词常可省略。例如:

When ( the museum is ) completed , the museum will be open to the public next year .

He’ll go to the seaside for his holiday if (it is ) possible.

3)固定句式:A is to B what C is to D 例如:

Nine is to three what three is to one.

另外,比较状语从句经常省略。例如:

I’m taller than he (is tall ).

The higher the temperature (is), the greater the pressure (is ).

就状语从句而言,有时为了使语言言简意赅,常常将状语从句进行"简化"。状语从句的"简化"现象在口语中较为普遍,而且在高考中的复现率也较高。因此,有必要对其进行全面、透彻的了解。

状语从句的"简化"现象常存在于以下五种状语从句中:①由if, unless等引导的条件状语从句;②由although, though, even if / though等引导的让步状语从句;③由when, while, as, before, after, until / till等引导的时间状语从句;④由as, as if等引导的方式状语从句;⑤由as, than等引导的比较状语从句。下面针对这五种情形作一归纳。

(1)当状语从句的主语是it,且谓语动词是be时,it和be要完全简化掉。例如:

If (it is) possible, he will help you out of the difficulty.如果可能的话,他会帮你摆脱困境。

You must attend the meeting unless (it is) inconvenient to you.除非情况对你来说不方便,否则你必须出席这次会议。

(2)当状语从句的主语和主句的主语一致时,从句可以将主语和be动词简化掉。常用于以下几种情形:

a.连词+形容词

As (he was) young, he learned how to ride a bike.他小时候就学会了骑自行车。

Whenever (she is) free, she often goes shopping.她有空就去逛商店。

Work hard when (you are) young, or you'll regret.少壮不努力,老大徒伤悲。

b.连词+名词

While (he was) a young boy, he was always ready to help others.他在孩子时代就乐于助人。

Although (he was) a farmer, now he is a famous director.尽管他曾是个农民,但现在他是位著名的导演了。

c.连词+现在分词

As (she was) walking along the river bank, she was singing a pop song.她沿着河堤边走边唱着流行歌曲。

Although (he is) doing his best in maths these days, he has still got no good marks.尽管近来他一直在学数学,但他仍然没有取得好成绩。

d.连词+过去分词

He won't go there with us unless (he is) invited.除非受到邀请,否则他不会和我们一道去那里。

The concert was a great success than (it was) expected.这场音乐会出乎意料地取得了巨大成功。

e.连词+不定式
