语法基础3第八节(2)——细说状语从句
一、 状语从句
1、 状语从句的构成
句式 1:引导词(连词)+状语从句+“,”+主句
句式 2:主句+引导词(连词)+状语从句
两个句式可以对调:
When I was young, I’d listen to the radio.
I’d listen to the radio when I was young.
2、状语从句引导词
状语从句的引导词是按照引导词本身的意思分的类,一共分为九类: 时间、地点、原因、目的、结果、条件、让步、方式和比较。
3、状语从句时态
1 )当主句谓语为过去时,从句谓语使用相应的过去时态。
When I entered the home, my husband had finished his meal. 我进屋时,我的丈夫已经吃完饭了。
2 )当主句谓语为将来时,从句谓语使用一般现在时,用“现在”表示“将来”。(换句话说:状语从句中,当主句和从句的动作都未发生时,主句使用一般将来时,从句用一般现在时表示将来。简称“主将从现”。)
If he accepts the offer, he’ll be going abroad. 如果他接受那个工作,他就要到国外去了。
二、九大状语从句
1、原因状语从句

4 )when 引导时间状语从句的特殊用法
when 引导时间状语从句 , 如果从句和主句的主语一致 , 并且从句的谓语中有 be 动词 , 那么从句的主语和 be 动词可以一起省略。
When I was a young girl, I would often listen to songs sung by Jeff zhang .
When a young girl, I would often listen to songs sung by Jeff zhang .(主语和谓语一致可省略)
当我还是小女孩时,我喜欢听张信哲的歌。
5 )区分 until 和 not... until
not until/until 两者皆可接延续性动词和暂短性动词.
a. not...until 翻译为 "直到 ......才”, 比如:

not until/until 两者皆可接延续性动词和暂短性动词.

until 指“直到”

小试牛刀

【翻译】 I did not realize how much time I had wasted until I began to work.

② 有志者事竟成。
Where there's a will, there's a way.(从句做状语)
There's a way with a will. (介词短语做状语)
