最简单的英语从句

主语从句，即在复合句中充当主语成分的句子，例如"Thathefinishedwritingthecompositioninsuchashorttimesurprisedusall"，他在很短的时间内写完作文让我们都很惊讶，此复合句主要描述的是某事让我们惊讶，某事就是该复合句的主语，因此"Thathefinishedwritingthecompositioninsuchashorttime"便是该复合句的主语从句。引导主语从句的连词主要有:从属代词:thatwhether；连接代词:whowhoeverwhomwhosewhatwhateverwhichwhichever；连接副词:whenwherehowwhy；主语从句的时态：不受主句的时态影响和限制。（1）Thathefinishedwritingthecompositioninsuchashorttimesurprisedusall.（2）Whetherwewillgoforanoutingtomorrowremainsunknown.（3）Whowillbeourmonitorhasn'tbeendecidedyet.（4）Whomwemuststudyforisaquestionofgreatimportance.（5）Whatcausedtheaccidentremainsunknown.（6）Whateveryoudidisright.（7）Whothewatchbelongstoisunknown.（8）Whatweneedistime.（9）Whatweneedaregooddoctors.小结（1）引导主语从句连词有that,whether,who,what,whatever等。（2）连词位于句首不能省略。（3）主语从句大多数情况下视为第三人称单数，但也有例外，如例（9）。
