2013年高考英语一轮复习学案专题12状语从句
【备考策略】
一、地点状语从句
地点状语从句通常由where, wherever 引导。

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。

他清了清嗓子像要说什么似的。

三、原因状语从句
比较because, since, as和for
1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.
