省略在状语从句中的运用

省略在状语从句中的运用
1.当主句的主语与状语从句的主语相同，且从句中的谓语是动词的情况下，可以省略状语从句中的主语和谓语。

例如：
- 原句：When I go to school, I always take the bus.
- 省略主语：When going to school, I always take the bus.
- 省略主语和谓语：Going to school, I always take the bus.
2.当主句的主语与状语从句的主语不同，且从句中的谓语是动词的情况下，可以省略状语从句中的主语，并保留谓语。

例如：
- 原句：When John goes to school, he always takes the bus.
- 省略主语：When going to school, he always takes the bus.
3. 当状语从句中的谓语是 be 动词时，可以省略主语和谓语，并保留 be 动词形式。

例如：
- 原句：When it is raining, I stay at home.
- 省略主语和谓语：When raining, I stay at home.
