“不及物動詞+介詞

/

副詞”構(gòu)成的短語動詞，變成被動句時，要把它們作為整體看待，介詞或副詞不可與其動詞拆開或漏掉。如：Ourhomeworkwashandedinyesterdayafternoon.Thehousewasfixedupbymyfather.2.

含有雙賓語的主動句變被動句時，可將主動句中的直接賓語或間接賓語變?yōu)楸粍泳渲械闹髡Z。如果把主動句中的直接賓語(指物)變?yōu)楸粍泳渲械闹髡Z，則需在間接賓語(指人)前加適當(dāng)?shù)慕樵~to或for。如:主動結(jié)構(gòu)：Dannygavemeaticketjustnow.被動結(jié)構(gòu)：AticketwasgiventomebyDannyjustnow.

(直接賓語作主語)IwasgivenaticketbyDannyjustnow.

(間接賓語作主語)3.

有些動詞常用其主動形式表示被動意義，如sell,wash,write等和表示感覺、知覺的系動詞feel,sound,taste,smell等。如：Thiskindofdresssellswell.Thefishtastesverydelicious.4.

在主動句中,使役動詞(如make等)和感官動詞(如see,watch,notice,hear等)后面常接不帶to的動詞不定式作賓語補(bǔ)足語;但在被動句中，這些詞后面的動詞不定式都需要帶to。如：Thebossmadeusworkfortenhourstoday.→Weweremadetoworkfortenhourstodaybytheboss.MomheardBensinginthenextroom.→BenwasheardtosinginthenextroombyMom.順口溜：感官動詞一感二聽三讓四看主動句中to離開，被動句中to回來Ⅳ.ExercisesI.完成句子1.______anewschool______(build)herelastyear?2.Thewater______(feel)coolwhenIjumpedintothepoolformorningexercise.
