一、方式状语从句
1、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:
Please do as what I told you. 请按照我告诉你的做。
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:
He looks as if( as though) he had been hit by lightning. 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 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。
2、其他的引导词
1) the way: Please pronounce the word the way I do.请照我这样,读这个单词
2)口语常用的 like: He sit there smiling like it was his birthday.他面带微笑坐在那儿,像是过生日似的 (这里用了虚拟语气,值得注意的是 be动词用的 was,而表示虚拟 as if引导的 be动词则只能是 were。)
地点状语从句表示地点、方位,这类从句通常由 where, wherever引导。例如:
Where there is a will, there is a way. 有志者, 事竟成。
They will go where they are happy. 他们想到他们觉得快乐的地方去。
二、地点状语从句
1、地点状语从句类型
1) Where+地点从句。 此句型通常译成“哪里……哪里就……”或“····的地方”。例如: Where there is no rain, farming is difficult or impossible.在没有雨水的地方,耕作是困难的,或根本不可能的。
They were good persons. Where they went, they were warmly welcomed. 他们都是好人。因此他们走到哪里都受到热烈欢迎。
You should have put the book where you found it. 你本来应该把书放回原来的地方。 We must camp where we can get water. 我们必须在能找到水的地方露营。
2) Anywhere/ wherever+地点从句,+主句。
anywhere本身是个副词,但是,常可以引导从句,相当于连词,意思相似于 wherever, anywhere引导的从句可位于主句之前,也可以位于主句之后。而 wherever本身就是个连词,表示“在何处,无论何处”。例如:
Wherever the sea is, you will find seamen.有海就有海员。
2、地点状语从句与定语从句的区别
二者区别在于分句在句中作什么成分。作状语,则是状语从句;作定语修饰名词,则是定语从句。 where引导定语从句时,从句前应有一个表示地点的名词作先行词;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)你从何处来到何处去。 Go back to the village where you came from.( where引导定语从句,修饰 village)回到你来的那个村子里去。
3、地点状语从句的省略,如: Fill in the blanks with articles necessary.( necessary前省略了 where it is)在需要的地方填上冠词。
