在初中范围复合句中主要有状语从句和宾语从句(名词性从句)两种,而定语从句(形容词性从句)要在高中讲述,为了使同学阅读文章方便,我们将在下面另一章予以介绍。我们首先来看宾语从句。① 在及物动词的后面可以接一个名词来充当宾语,如: I knew the man, 而这时也可以用一个句子来充当宾语,如: I knew that he was a good man? 这时宾语从句的连接词有 that, (that 只在从句中起联接作用,不在句中充当语法成分,既不是主语也不是宾语,所以在口语中常常被省略。如: I am sure (that) she has passed the exam? ②if, whether 它们在宾语从句中只起连接作用,不起语法作用,当作是否讲。从句中有 or not 结构时,要用 whether, 如: I ask him if (whether) he has had his lunch? I asks him whether he has had his lunch or not? ③ what 它在宾语从句中除了作连接词外,还要作主语或宾语成份,如: I don't understand what you said? (what 作 said 的宾语)。又如: I asked him what made him sick (what 在宾语从句中作主语)。④ who,它也和what一样,在句中除作连接词外,可以充当句中的成份,如:I know who she is looking for? ⑤ whose 如: I want to know whose book this is? ⑥ which 如: Do you know which book is mine??
