如果从句的主语和主句的主语一致，且从句的谓语含有be动词的某种形式（am/is/are/was/were），可同时省略从句的主语和be动词的某种形式。

when，while引导的时间状语从句

e.g. Do be careful when (you are) crossing the street.

When/While (I was) on my way to work, I met her.

if，unless，once引导的条件状语从句

e.g. If (it is) properly treated, waste will do no harm to the environment.

I’ll not go to the party unless (I am) invited.

Once (you are) caught stealing in a supermarket, you will be punished.

though，although，whether，no matter whether/what/how/who等引导的让步状语从句

e.g. He was happy, though/although (he was) poor.

Whether (she is) sick or well, she is always cheerful.

No matter how/However hard the task (is), we must fulfill it in time.（注：从句的主语和主句的主语不一致时，只省略从句中的be动词形式）

as if，as though引导的方式状语从句

e.g. He rubbed his eyes and yawned as if/though (he was) waking up after a long sleep.

He stood up as if/though (he wanted) to leave.（as if/though + to do表示一个将来的动作）
