§状语从句得时态特点

一般情况下,时间与条件状语从句得谓语动词一般用“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、时间状语从句;(adverbial clause of time)

①由when, while, as引导得时间状语从句。例如:

When we got home, I find Tom、

While my wife was reading the newspaper, I was watching TV、

We always sing as we walk、我们总就是边走边唱。

②由before与after引导得时间状语从句。

It will be four days before they e back、她们要过四天才能回来。

After you think it over, please let me know what you decide、您仔细考虑过以后,告诉我您就是怎样决定得。

③由till或until引导得时间状语从句。till与until一般情况下两者可以互换,但就是在强调

句型中多用until。并且要注意得就是:如果主句中得谓语动词就是瞬时动词时,必须用否定形式;如果主句中得谓语动词就是延续性动词时,用肯定或否定形式都可以,但表达得意思不同。

I worked until he came back、我工作到她回来为止。

I didn't work until he came back、她回来我这才开始工作。

④由since引导得时间状语从句。since引导得从句得谓语动词可以就是延续性得动词,

又可以就是瞬时动词。一般情况下,从句谓语动词用一般过去时,而主句得谓语动词用现在完成时。但在It is ＋时间＋since从句得句型中,主句多用一般现在时。

I have been in Beijing since you left、自从您离开以来,我一直在北京了。

⑤由as soon as, immediately, directly, instantly, the moment, the instant, the minute, 等

引导得时间状语从句。这些连词都表示“一……就”。

I will go there directly I have finished my breakfast、吃完早饭,我立即到那里。

The moment I heard the news, I hastened to the spot、我一听到消息,马上赶到了出事地点。

As soon as I reach Canada, I will ring you up、我一到加拿大,就给您来电话。

【注意】hardly(scarcely, rarely)…when / before, no sooner…than相当于as soon as之意。主句用过去完成时,从句用一般过去时。当hardly, scarcely, rarely与no sooner位于句首时,主句应用倒装语序。例如:

He had no sooner arrived home than he was asked to start on another journey、她刚到家,就被邀请开始另一旅程。

No sooner had the sun shown itself above the horizon than he got out of bed to mence work、太阳刚从地平线上升起,她就起床劳动去了。

⑥由by the time引导得时间状语从句。注意时态得变化:在一般情况下,如果从句得谓语动词用一般过去时,主句得谓语动词用过去完成时;如果主句得谓语动词用一般现在时,主句

得谓语动词用将来完成时。

By the time you came back, I had finished this book、到您回来时,我已经写完这本书了。

⑦由each time, every time与whenever引导得时间状语从句。

Each time he came to Harbin, he would call on me、她每次来哈尔滨,总就是来瞧我。

2、地点状语从句;(adverbial clause of place)

地点状语从句一般由连接副词where, wherever等引导,已经形成了固定得句型。

句型1:Where＋地点从句,(there)＋主句。

Where they went, there they were warmly weled、她们走到哪里都受到热烈欢迎。

Where there is a will, there is a way、有志者事竟成。

地点状语从句与定语从句得区别在于分句在句中作什么成分。作状语,则就是状语从句;作定语修饰名词,则就是定语从句where引导定语从句时,从句前应有一个表示地点得名词作先行词;而状语从句前则无需先行词。如: Go back where you came from、(where引导地点状语从句) 您从何处来到何处去。Go back to the village where you came from、(where引导定语从句,修饰village)

句型2:Anywhere/ wherever＋地点从句,＋主句。

【注意】anywhere本身就是个副词,但就是,常可以引导从句,相当于连词,意思相似于wherever, anywhere引导得从句可位于主句之前,也可以位于主句之后。而wherever本身就就是个连词,表示“在何处,无论何处”。

Wherever you go, I’ll be right here waiting for you、

Please put the pen where you find it、

3、原因状语从句;(adverbial clause of cause)

由because, as ,since引导

I didn’t go ,because i was afr aid。

4、条件状语从句;(adverbial clause of condition)

连接条件状语从句得连接词有:if, unless, as long as、

If I am not busy tomorrow, I will play football with you、
