宾语从句复习要点
学习宾语从句,我们应该注意三个方面:连接词、语序和时态。
一、连接词
1. that引导宾语从句时,that只起连接作用,不充当句子成分,也没有词义,常可省略。如:
●I know(that) he is a Canadian athlete.
2. whether或if引导宾语从句时,whether或if在句中不充当句子成分,意为“是否”,不可省略。如:
●I don’t know whether/ if my parents agree with me.
注意:与or not直接连用时只能用whether不可用if。如:
●He didn’t say whether or not he would be staying here.
