二、状语从句的省略:

When (she was) very young, she began to learn to play erhu.
Whenever (it is) possible, you should come and help.

省略式的条件状语从句句型为if necessary, if possible, if true, if anyone等。Unless, once, as long as 等词或短语后也运用省略形式。
He will come if (he is ) asked.
Send the goods now if (they are ) ready.
3. 让步状语从句的省略:
He is a good man, though sometimes (he is ) rather dull.
Even if ( I am ) invited to, I won’t go to such a bad lecture.
4. 比较状语从句中的省略:

6. 方式状语从句中的省略:
as if/ as though 后可以加名词、形容词、副词、介词短语、动词ing形式、动词ed形式、不定式。

He moved his lips as if (he wanted )to speak.
7. 其他特殊情况:
(1)状语从句中主语尽管和主句不同,但如果根据主、从句的对应关系判断,意思比较明确,同时,从句的谓语又含有动词“be”的某种形式,则可省略从句中的”主语+be”部分。
There are a few simple safety measures to follow while (you are) training.
(2).如果状语从句和主句都含有there be 的某种形式或只有状语从句含有there be 的某种形式,从句中的there be 常常可以省略。
Correct the mistakes, if (there are )any (mistakes) in these sentences.
