如何判断一个从句是宾语从句？ V I think 双宾语 I tell him that + 宾语从句 介宾短语 I think about The Object Clause 宾语从句 宾语从句三要点 一、语序 二、时态 三、引导词 1. 由that引导的宾语从句。That只有语法作用，没有实在的意义，在口语和非正式文体中可以省略。例如： He said (that) he wanted to stay at home. She doesn’t know (that) she is ill. I am sure (that) he will succeed. ?? ? 宾语从句的类型 2. 由if或whether引导的宾语从句。If和whether在句中的意思是“是否”。 I want to know if (whether) he lives there. He asked me whether (if) I could help him. 3. 由连接代词who, whom, whose, what, which和连接副词when, where, why, how引导的宾语从句。这些连接代词和连接副词在宾语从句中充当某个成分。例如： Do you know who (whom) they are waiting for? He asked whose homework was the best. Can you tell me where the No.3 bus stop is? I don’t know why the train is late. ???? 1. 主句是一般现在时，宾语从句可以用任何一种时态????? I hear ( that ) Tom has been to Guilin twice .????? I hear ( that ) she will come tomorrow .????? I hear ( that ) Jim went to work an hour ago .?????
