3、作用的句子叫宾语从句，宾语从句放在及物动词或介词之后作宾语。宾语从句的结构主句 + 连接词(引导词) + 宾语从句I dont know why he is always late for school.We all agree with what you said at the meeting.（3）表语从句 表语从句位于连系动词后,有时用as if引导。结构为:主语 + 系动词 + that从句1. be, look, remain, 等系动词后均可跟表语从句：My suggestion is that we should go shopping.2. as if 也可引导表语从句。It
