主動語態(tài)表示主語是動作的執(zhí)行者。巧記為：主動、主動、主去動。

例如：ManypeoplespeakEnglish.

謂語speak的動作是由主語manypeople來執(zhí)行的。

被動語態(tài)表示主語是動作的承受者，即行為動作的對象。巧記為：被動、被動、主被動。

例如：Englishisspokenbymanypeople.

主語English是動詞speak的承受者。把下列句子變?yōu)楹粍诱Z態(tài)的句子：1.Mr.Licorrectsthestudents'homeworkeverymorning.Thestudents'homeworkiscorrectedbyMr.Lieverymorning.2.Peopleplaybasketballallovertheworld.Basketballisplayedbypeopleallovertheworld.主語主語謂語賓語謂語賓語語法點擊一般過去時的被動語態(tài)1.概念：一般過去時的被動語態(tài)表示主語是過去某個動作的承受者。2.構(gòu)成：主語＋was/were＋動詞的過去分詞。Somenewcomputerswerestolenlastnight.昨天晚上有幾臺新電腦被盜了。Summary:Whathaveyoulearnt?1.句型whenwasthecarinvented?
