【英语宾语从句】在英语语法中,宾语从句是句子中充当宾语的从句,通常跟在动词、介词或某些形容词之后。它在句中起名词作用,用来说明主句中动词、介词或形容词所表达的内容。掌握宾语从句的结构和用法,有助于提高英语写作与口语表达的准确性。
一、宾语从句的基本结构
宾语从句一般由连接词引导,常见的连接词包括:
- that(可省略)
- if / whether
- wh-疑问词(如 what, when, where, why, how, who, whom, whose, which)
例如:
- I think that he is right.
- She asked whether she could come.
- They wondered what the problem was.
二、宾语从句的语序
宾语从句中的语序应为陈述语序,而不是疑问语序。
错误:
I don’t know why did he leave.
正确:
I don’t know why he left.
三、宾语从句的时态一致性
主句如果是现在时或将来时,从句可以用任何时态;
如果主句是过去时,从句一般要用相应的过去时态。
例如:
- He says he is coming.(现在时)
- He said he was coming.(过去时)
- She asked if I had finished my work.(过去完成时)
