madeherparentsbothworriedandproud.（主语从句，that不能省略）Thefactisthatheisoldenoughtogotoschool.（表语从句，that一般不省略）Heishesitatingaboutwhetherheshouldtellherthetruth.（宾语从句）Hefeltasifhehadgonebackto20yearsago.（表语从句）连词：此外，it作形式主语和形式宾语时，一般将替代它的主语从句和表语从句后置。例如：Itisreportedthatsevenpeoplehavebeenseriouslyinjuredintheaccident.（it作形式主语）Ileaveittoyourownjudgementwhetheryoushoulddoit.（it作形式宾语）主语从句、宾语从句、表语从句所使用的引导词大体相同，但有些仅常用于某种名词性从句，如because，asif，asthough仅常用于表语从句，whether和if均可用于宾语从句，但在主语从句和表语从句中一般只用whether。注意引导宾语从句的that常常省略，特别是在非正式语体中。如：Hertutorexplainedthatshewassupposedtoreadlotsofinformationtohelpformawiseopinionofherown.
