请说一下宾语从句的连接词
宾语从句的连接词主要包括以下三类:1.连词that,只起连接作用,在从句中不作句子成分,也无词汇意义,在口语中常被省略. eg. He knew (that) he should work hard. 2.连词if 、whether,它们起连接作用,在从句中不作句子成分,作“是否”解,在口语中多用if. eg. Tom don't know if/whether his grandpa liked the present. He asked me whether or not I was coming. 一般情况下,if 和whether可以互换,但以下3种情况只能用whether: ①在不定式前:__________to go there or not hasn't been decided. ②在介词前:It depends on(依靠) ___________ it is going to rain. ③与or not连用:They are talking about _______________ to go there or not. 3.连接代词who, whom, whose, what, which,连接副词when, where, why, how, 它们起连接作用,作句子成分,各有自己的意义. eg. The teacher asked the new students which class he was in. I wonder where he got so much money.定语从句的连接词可以参见如下表格:满意请采纳
