Passivevoice被動語態(tài)

主動句變?yōu)楸粍泳渌裱?個步驟：1.把原主動句中的賓語變?yōu)楸粍泳涞闹髡Z。2.把動詞變?yōu)楸粍有问郊碽e+過去分詞，并注意其人稱和數(shù)隨主語的變化，而動詞的時態(tài)則保持不變。3.原主動句的主語如需要則放在by后面以它的賓格形式出現(xiàn)（注代詞的賓格），如不需要則可省略。4.其它的成分（定語、狀語）不變。不知道動作的執(zhí)行/實施者強調(diào)動作的承受者出于禮貌等原因不愿說出執(zhí)行/實施者何時用被動語態(tài)?

在英語中，動詞有兩種語態(tài)，即主動語態(tài)和被動語態(tài)。被動語態(tài)的基本結(jié)構(gòu)是“be+及物動詞的過去分詞”，其中be有人稱、數(shù)和時態(tài)的變化。一般現(xiàn)在時的被動語態(tài)構(gòu)成助動詞be＋

及物動詞的過去分詞助動詞be有人稱、時態(tài)和數(shù)的變化

當主語為動作的執(zhí)行/實施者時，謂語的形式為主動語態(tài)；當主語為動作的承受者時，謂語要用被動語態(tài)。被動語態(tài)定義

注意：在主動語態(tài)句中動詞make、have、let、see、watch、hear、feel等后接動詞不定式作賓語補足語，動詞不定式不加to。但變成被動語態(tài)時后面的不定式都須加上to。

→Theyaremadetoworktenhoursaday.→HislittlesisterislettowaterflowerseverydaybyTom.
