狀語(yǔ)從句要有一個(gè)連詞引導(dǎo)，即引導(dǎo)詞。在實(shí)際使用時(shí)我們經(jīng)常會(huì)做錯(cuò)，因?yàn)橛行┮龑?dǎo)詞有它們的特殊含義，有些句型容易混淆。這里將狀語(yǔ)從句中易錯(cuò)的句型和引導(dǎo)詞的特殊用法小結(jié)如下：

1. when

1） 意為“當(dāng)……時(shí)候”。

例如：

Because of the heavy traffic， it was already time for lunch break she got to her office.

A. since B. that

C. when D. until

該題正確答案為C。

2） 意為“這時(shí)”，強(qiáng)調(diào)突然性，常用在以下句型中：

a. be doing ... when ...

b. had done ... when ...

c. be about to do ... when ... = be on the point of doing ... when ...

例如：

A. when B. if

C. and D. till

該題正確答案為A 。

3） 意為“在……情況下（表驚訝）”。

4. 祈使句“... and / or + youll ...”

祈使句“... and / or + youll ...”結(jié)構(gòu)相當(dāng)于由if引導(dǎo)的條件句。

例如：

= Get up early， and youll catch the first bus.

2） If you dont get up early， youll be late.

此句還要注意和強(qiáng)調(diào)句結(jié)構(gòu)的區(qū)別

It was nine oclock when I got home. （狀語(yǔ)從句）

It was at nine oclock that I got home. （強(qiáng)調(diào)句）
