方式状语从句
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。
You must try to hold the tool as I do.
你必须像我这样拿工具。
Leave the things as they are.
别动这些东西。
We must do as the Party tells us (to do).
我们必须按照党的指示办事。.
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)由as if, as though引导
as if 和as though 引导的从句中的时态取决于说话者对所谈内容的态度。若说话者认为其看法是真的或可能会成为事实,从句谓语就按常规变化。
例如:
He looks as if he is angry.
他看上去好像生气了。
It looked as if there would be an exciting race.
看来要有一场激动人心的比赛。
When the soaceship leaves the earth at tremendous speed,the astronauts feel as if they are being crushed against the spaceship floor.
当宇宙飞船以巨大的速度离开地球时,宇航员们觉得自己好像正在被压向宇宙飞船的底壁上去。
如果从句的内容是不真实的,是与事实相反的,从句的谓语时态要用虚拟语气。主句谓语用一般现在时态,对从句的谓语形式没有影响。
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
