Question

非谓语动词在复合句中,从句可以用谓语动词么?When he was waiting for the bus,he saw

Answer 1

首先,两句句子是不能用一个逗号逗开的,必须要一个连词连接.

如果没有连词,必定会出现非谓语,有两个动词的时候,一个是真正谓语,另一个就是非谓语,所以要注意确认哪个是真正的谓语动词.

When he was waiting for the bus,he saw a dog.句中When是连词,连接了两句句子,所以不需要用非谓语.

Waiting for the bus,he saw a dog.句中没有连词,所以waiting是非谓语,saw是真正谓语,非谓语和主语he是主谓关系
