的事（物、话），相当于thethingthat或thethingwhich。that本身没有词汇意义，在名词从句中不充当任何成分，在口语和非正式文体中，宾语从句中的that经常省略。如：,精选ppt出品,(1)Whatyouhavedonemightdoharmtoothers.(2)Whatcausedtheaccidentisacompletemystery.(3)Ithink(that)youwilllikethestamps.,精选ppt出品,2、whether与ifwhether与if在前面已经说过.,精选ppt出品,1、Myhometownisnolonger_itusedtobe.（）,练习题：,A、thatB、whatC、whenD、which,B,精选ppt出品,2、Theywonder_theirsonwasgettingalongwithhisstudy.（）,A、whetherB、thatC、whatD、how,D,精选ppt出品,3、_heislivingnowisnotknowntoanybody.（）,A、WhenB、IfC、WhetherD、Why,C,精选ppt出品,4、Wordcame_Iwasinvitedtoattendthemeeting.（）,A、whichB、whenC、whereD、that,D,精选ppt出品,5、Thefact_wewereinterestedin_allofthem.（）,A、that;wassurprisedB、which;surprisedC、what;wassurprisedD、when;surprised,B,精选ppt出品,6、_thescientistwhogaveusatalkwillgoabroad.（）,A、ItsaidthatB、ItsayswhenC、ItissaidthatD、Heissaid,C,精选ppt出品,7、Hetoldme_there.（）,A、thathasbeenhappenedB、thathappenedC、whathadhappenedD、whathadbeenhappened,精选ppt出品,7、Hetoldme_there.（C）,A、thathasbeenhappenedB、thathappenedC、whathadhappenedD、whathadbeenhappened,精选ppt出品,8、_Icantunderstandis_hechangedhismind.（）,A、That;thatB、What;whyC、Which;howD、That;why,B,精选ppt出品,9、_hisbrotheris?（）,A、WhatdoyousupposeB、WhatyousupposeC、WhatdoyousupposethatD、Yousupposethat,精选ppt出品,9、_hisbrotheris?（A）,A、WhatdoyousupposeB、WhatyousupposeC、WhatdoyousupposethatD、Yousupposethat,精选ppt出品,10、Thereason_hedidntcometoschoolyesterdayis_hehadtolookafterhissickmotherathome.（）,A、that;becauseB、why;forC、for;thatD、why;that,D,精选ppt出品,11、Weallknowthetruth_theearth_roundthesun.（）,A、if;movedB、that;movesC、why;moveD、whether;move,B,精选ppt出品,12、_hesaidatthemeetingisveryimportanttous.（）,A、ThatB、WhatC、WhichD、Whether,B,精选ppt出品,13、_thebabycouldspeakmadehisparentsveryhappy.（）,A、Tha
