2.原因状语从句

由because 、 since 、 as 〔因为、既然、由于〕引导的原因状语从句。

3.地点状语从句

由wherever 〔无论在哪儿〕引导的地点状语从句。

4.目的状语从句

由so that ( 以便、为的是 ) 引导目的状语从句。

5.条件状语从句

由 if或unless引导条件状语从句。

6.比拟状语从句

由than 、 as ⋯ as、 not as ⋯⋯ as 引导比拟状语从句。

二、状语从句与主句的时态问题

1.时间状语从句、条件状语从句与主句的时态不一致。〔主句用将来时，而时间、条件状语从句用一般现在时〕

If it ________(not rain) tomorrow, we______(go) to climb the hill.

He ________ (become) a sodier when he ______(grow) up. 2.

一般过去时

since 引导的时间状语从句。 It is + 时间 + since +

It_____(be) ten years since we ________(leave) that city.

3.由when、while引导的时间状语从句的时态：

主句〔过去进展时〕+when +从句〔一般过去时〕

主句〔一般过去时〕+when +从句〔过去进展时〕

主句〔一般过去时〕+while +从句〔过去进展时〕

主句〔过去进展时〕+while +从句〔过去进展时〕

注意：看动词为短暂性动词用一般过去时，动词为延续性动词那么用过去进展时。

Mother _______(cook)supper when I ______(get)home yesterday.

Last Sunday I_______(meet)Lin Hong when I _______(walk)in the street.

While Han Meimei _______(sweep)the floor, Lucy _______(carry) water.

When the students ________(have)a meeting, the teacher _______(come) in.

4.由when、after、before、by the time引导的时间状语从句的时态：

主、从句的谓语动作都以完成，那么先发生的动作用过去完成时，后发生的动作用一般过去时。When they _______(get) to the cinema last light, the film ________(start).

I _________(go) out with my friends after I _______(finish) all the homework last

night.
