初中从句类型【宾语从句】 宾语从句由关系代词或关系副词引出。我们根据引导宾语从句的连词不同,可把宾语从句分为三类。 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 dont 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 didnt say whether or not he would be staying here.3. what, who, whose, which等连接代词和when, where, how, why等连接副词引导宾语从句时,这些词在从句中充当一定的句子成分,都有各自的词义,
