2.定語從句是對先行詞起修飾作用，而同位語從句則解釋說明先行詞的具體內(nèi)容。(同從)(定從)請判斷出下列的句子屬于哪種從句WhatIwanttodoistakingabath.Thenewsthattheywonthegamespreadthewholeschool.Idon’tthinkheisanhonestboy.Thefactisthathestolethecar.Doyouknowthefactthathestolethecar?Doyouknowthemanwhoisstandingoverthere?Itissaidthattheywonthegame.(主從)(同位語從句)(賓從)(表從)(同位語從句)(定從)(主從)03單擊此處添加副標(biāo)題內(nèi)容引導(dǎo)詞的分類名詞性從句的引導(dǎo)詞既可以有含義，又可以在句子當(dāng)中充當(dāng)成分。eg.WhoIrespectmostismymathteacher.ThepersonwhoIrespectmostismymathteacher.引導(dǎo)詞包括

作文總愛犯這樣的錯

由于名詞性從句引導(dǎo)詞與定語從句，狀語從句引導(dǎo)詞重復(fù)的較多，容易形成混雜，因此同學(xué)們需要注意訓(xùn)練區(qū)分各類從句判斷以下句子是什么從句Sheisthegirlthattalkedtoyouyesterday.ThebookwhichIboughtlastweekwaslost.Thefactisthathestolethecar.MrLiuisthepersonwhomyoutalkedaboutonthebus.I'lltellyouwhenIcomebacksoyoucanpickmeupontime.Hewasalwaystryingoutnewideaswhenhewasachild.Youshouldhaveputthebookwhereyoufoundit.定從定從同位語從定從名詞性從句狀從狀從05單擊此處添加副標(biāo)題內(nèi)容配套練習(xí)1.____LiBai,agreatChinesepoet,wasbornisknowntothepublic,butsomewon’tacceptit.
