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：hesaid(that)hewantedtostayathome.shedoesn’tknow(that)sheisseriouslyill.iamsure(that)hewillsucceed.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：doyouknowwho(whom)theyarewaitingfoe?heaskedwhosehandwritingwasthebest.canyoutellmewheretheno.3busstopis?idon’tknowwhythetrainislate.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：iwanttoknowif(whether)helivesthere.heaskedmewhether(if)icouldhelphim.

宾语从句 一 定义 :在复合句中起宾语作用的从句叫做宾语从句. 二 种类 : 1 由that引导的宾语从句－－－当从句是陈述句时,用that引导宾语从句．在口语和非正式文体中,that可以省略 I know ( that ) you like English . He told me ( that ) he would go there next week . 2 由whether / if 引导的宾语从句－－－当从句是一般疑问句,选择疑问句或反意疑问句时,用whether / if引导宾语从句,并且要把疑问的语序变为陈述的语序．一般情况下,whether / if可以替换．但下面四种情况,只能用whether引导宾语从句． He asked me whether / if I liked my job .
