WhatThatThatwhat

与that在引导主语从句时的区别what在从句中充当句子成分，如主语、宾语、表语，而that则不然。

What功能连接词不作成分that,whether作主、宾、表、what,who,whom,wh+ever作定语which,whose,作状语when,where,why,howUsageoftheConjunctions缺什么补什么学法指导依据“缺什么补什么”原则确定正确的连词。所谓“缺什么补什么”是指从句与连词之间的关系。如果句子中缺主语，指人用who，指物用what。如缺宾语，指人用whom，指物用what。如缺时间状语用when；地点状语用where。

原因状语用why；方式状语用how。如缺定语用whose或which。如什么都不缺用that，whether表“是否”。探寻规律1：
