什么样的是含有宾语从句的复合句

宾语从句的复合句.  概念:复合句也称主从句,即主句和从句,从句须有引导词或叫连词引出,否则复合句不成立.由于连词既起连接主句和从句的作用,表明主从句之间的关系,还在从句中充当一定的成份,有一定的意义,故复合句中的连词常成为考查的焦点.  种类分为:  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 seriously ill.I am sure (that) he will succeed.2.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 handwriting was the best.Can you tell me where the No.3 bus stop is?I don’t know why the train is late.3.由if或whether引导的宾语从句.If和whether在句中的意思是“是否”.例如:I want to know if (whether) he lives there.He asked me whether (if) I could help him.注意一下情况只用whether,不用ifwhether引导的从句常可以与连词or或or not直接连用.如:正:Let me know whether you can come or not.误:Let me know if you can come or not.当宾语从句提到句首时,只能用whether引导.如:正:Whether it is true or not,I can’t tell.误:If it is true or not,I can’t tell.3.whether可以引导带to的不定式.如:正:I don’t know whether to accept or refuse.误:I don’t know if to accept or refuse.4.whether及其引导的成分可放于介词之后,作介词的宾语.如:正:I worry about whether I hurt her feelings.误:I worry about if I hurt her feelings.
