“不及物动词+介词

/

副词”构成的短语动词，变成被动句时，要把它们作为整体看待，介词或副词不可与其动词拆开或漏掉。如：Ourhomeworkwashandedinyesterdayafternoon.Thehousewasfixedupbymyfather.2.

含有双宾语的主动句变被动句时，可将主动句中的直接宾语或间接宾语变为被动句中的主语。如果把主动句中的直接宾语(指物)变为被动句中的主语，则需在间接宾语(指人)前加适当的介词to或for。如:主动结构：Dannygavemeaticketjustnow.被动结构：AticketwasgiventomebyDannyjustnow.

(直接宾语作主语)IwasgivenaticketbyDannyjustnow.

(间接宾语作主语)3.

有些动词常用其主动形式表示被动意义，如sell,wash,write等和表示感觉、知觉的系动词feel,sound,taste,smell等。如：Thiskindofdresssellswell.Thefishtastesverydelicious.4.

在主动句中,使役动词(如make等)和感官动词(如see,watch,notice,hear等)后面常接不带to的动词不定式作宾语补足语;但在被动句中，这些词后面的动词不定式都需要带to。如：Thebossmadeusworkfortenhourstoday.→Weweremadetoworkfortenhourstodaybytheboss.MomheardBensinginthenextroom.→BenwasheardtosinginthenextroombyMom.顺口溜：感官动词一感二听三让四看主动句中to离开，被动句中to回来Ⅳ.ExercisesI.完成句子1.______anewschool______(build)herelastyear?2.Thewater______(feel)coolwhenIjumpedintothepoolformorningexercise.
