一地点状语从句地点状语从句通常由where, wherever 引导。

Where I live there are plenty of trees.我住的地方树很多。

Wherever I am I will be thinking of you. 不管我在哪里我都会想到你。

二. 方式状语从句方式状语从句通常由as, (just) as…so…, as if, as though引导。

1)as, (just) as…so…引导的方式状语从句通常位于主句后,但在(just) as…so…结构中位于句首,这时as从句带有比喻的含义,意思是"正如…","就像",多用于正式文体,例如:Always do to the others as you would be done by.你希望人家怎样待你,你就要怎样待人。

As water is to fish, so air is to man.我们离不开空气,犹如鱼儿离不开水。

Just as we sweep our rooms, so we should sweep backward ideas from our minds.正如打扫房屋一样,我们也要扫除我们头脑中落后的东西。

2)as if, as though两者的意义和用法相同,引出的状语从句谓语多用虚拟语气,表示与事实相反,有时也用陈述语气,表示所说情况是事实或实现的可能性较大。

汉译常作"仿佛……似的","好像……似的",例如:They completely ignore these facts as if (as though) they never existed.他们完全忽略了这些事实,就仿佛它不存在似的。

(与事实相反,谓语用虚拟语气。

)He looks as if (as though) he had been hit by lighting.他那样子就像被雷击了似的。

(与事实相反,谓语用虚拟语气。

)It looks as if the weather may pick up very soon.看来天气很快就会好起来。

(实现的可能性较大,谓语用陈述语气。

)说明:as if / as though也可以引导一个分词短语、不定式短语或无动词短语,例如:He stared at me as if seeing me for first time.他目不转睛地看着我,就像第一次看见我似的。

He cleared his throat as if to say something.他清了清嗓子,像要说什么似的。

The waves dashed on the rocks as if in anger.波涛冲击着岩石,好像很愤怒。

三. 原因状语从句比较:because, since, as和for1)because语势最强,用来说明人所不知的原因,回答why提出的问题。

当原因是显而易见的或已为人们所知,就用as或since。

I didn't go, because I was afraid.Since /As the weather is so bad, we have to delay our journey.2)由because引导的从句如果放在句末,且前面有逗号,则可以用for来代替。

但如果不是说明直接原因,而是多种情况加以推断,就只能用for。

He is absent today, because / for he is ill.He must be ill, for he is absent today.四. 目的状语从句表示目的状语的从句可以由that, so that, in order that, lest, for fear that, in case等词引导,例如:You must speak louder so that /in order that you can be heard by all.He wrote the name down for fear that(lest) he should forget it.Better take more clothes in case the weather is cold.五. 结果状语从句结果状语从句常由so… that 或such…that引导,掌握这两个句型,首先要了解so 和such 与其后的词的搭配规律。

比较:so和such其规律由so与such的不同词性决定。

such 是形容词,修饰名词或名词词组,so 是副词,只能修饰形容词或副词。

so 还可与表示数量的形容词many, few, much, little连用,形成固定搭配。

so foolish such a foolso nice a flower such a nice flowerso many / few flowers such nice flowersso much / little money. such rapid progressso many people such a lot of people(so many 已成固定搭配,a lot of 虽相当于many,但 a lot of 为名词性的,只能用such 搭配。

)so…that与such…that之间的转换既为so与such之间的转换。

The boy is so young that he can't go to school.He is such a young boy that he can't go to school六条件状语从句连接词主要有if, unless, as/so long as, on condition that 等。

.if 引导的条件句有真实条件句和非真实条件句两种。

非真实条件句已在虚拟语气中阐述。

unless = if not.Let's go out for a walk unless you are too tired.If you are not too tied, let's go out for a walk.典型例题You will be late ___ you leave immediately.A. unlessB. untilC. ifD. or答案A。

句意:除非你立即走,否则你就回迟到的。

可转化为If you dong leave immediately, you will be late.B、D句意不对,or表转折,句子如为You leave immediately or you will be late.七.让步状语从句though, although注意:当有though, although时,后面的从句不能有but,但是though 和yet可连用Although it's raining, they are still working in the field.虽然在下雨,但他们仍在地里干活。

He is very old, but he still works very hard.虽然他很老,但仍然努力地工作。

Though the sore be healed, yet a scar may remain.伤口虽愈合,但伤疤留下了。

(谚语)典型例题1)___she is young, she knows quite a lot.A. WhenB. HoweverC. AlthoughD. Unless答案:C。

意为虽然她很年轻,却知道许多。

2)as, though 引导的倒装句as / though引导的让步从句必须表语或状语提前(形容词、副词、分词、实义动词提前)。

Child as /though he was, he knew what was the right thing to do.= Though he was a small child, he knew what was the right thing to do.注意:a.句首名词不能带任何冠词。

b.句首是实义动词,其他助动词放在主语后。

如果实义动词有宾语和状语,随实义动词一起放在主语之前。

Try hard as he will, he never seems able to do the work satisfactorily.= Though he tries hard, he never seems…虽然他尽了努力,但他的工作总做的不尽人意。

3)ever if, even though.即使We'll make a trip even though the weather is bad.4) whether…or-不管……都Whether you believe it or not, it is true.5)"no matter +疑问词" 或"疑问词+后缀ever"No matter what happened, he would not mind.Whatever happened, he would not mind.替换:no matter what = whateverno matter who = whoeverno matter when = wheneverno matter where = whereverno matter which = whicheverno matter how = however注意:no matter 不能引导主语从句和宾语从句。

(错)No matter what you say is of no use now.(对)Whatever you say is of no use now.你现在说什么也没用了。

(Whatever you say是主语从句)(错)Prisoners have to eat no matter what they're given,(对)Prisoners have to eat whatever they're given.囚犯们只能给什么吃什么。

八时间状语从句比较while, when, as1)as, when 引导短暂性动作的动词。

Just as / Just when / When I stopped my car, a man came up to me.2)当从句的动作发生于主句动作之前,只能用when 引导这个从句,不可用as 或while。
