用来充作宾语的句子叫做宾语从句。如:
He asked what you were doing last night. 他问你昨天夜晚在干什么。
I didn’t know that he was wounded in the accident. 我原来不知道他在那事故中受了伤。
Can you explain why he didn’t come to the party last Sunday? 你能解释上周星期日他为什么没有来参加聚会吗?
在宾语从句中须注意:
1. that 在口语中常被省略,但在正式的文体中,不能省;并且它一般不能引导介词的宾语从句,但可引导except, but, in 等少数介词的宾语从句。如:
I didn’t know (that) he was Li Lei. 我不知道他就是李蕾。
I will do anything I can to help you except that I’m ill. 只要我身体舒服,我愿做任何事情来帮助你。
2. 宾语从句之后带有补足语成分时,一般须用it作形式宾语,把宾语从句放到句末,此时的that不能省。如:
The boy has made it clear that they can’t play with his toys. 那个男孩已清楚的表明他们不能玩弄他的玩具。
