主動(dòng)語(yǔ)態(tài)表示主語(yǔ)是動(dòng)作的執(zhí)行者。巧記為：主動(dòng)、主動(dòng)、主去動(dòng)。

例如：ManypeoplespeakEnglish.

謂語(yǔ)speak的動(dòng)作是由主語(yǔ)manypeople來(lái)執(zhí)行的。

被動(dòng)語(yǔ)態(tài)表示主語(yǔ)是動(dòng)作的承受者，即行為動(dòng)作的對(duì)象。巧記為：被動(dòng)、被動(dòng)、主被動(dòng)。

例如：Englishisspokenbymanypeople.

主語(yǔ)English是動(dòng)詞speak的承受者。把下列句子變?yōu)楹粍?dòng)語(yǔ)態(tài)的句子：1.Mr.Licorrectsthestudents'homeworkeverymorning.Thestudents'homeworkiscorrectedbyMr.Lieverymorning.2.Peopleplaybasketballallovertheworld.Basketballisplayedbypeopleallovertheworld.主語(yǔ)主語(yǔ)謂語(yǔ)賓語(yǔ)謂語(yǔ)賓語(yǔ)語(yǔ)法點(diǎn)擊一般過(guò)去時(shí)的被動(dòng)語(yǔ)態(tài)1.概念：一般過(guò)去時(shí)的被動(dòng)語(yǔ)態(tài)表示主語(yǔ)是過(guò)去某個(gè)動(dòng)作的承受者。2.構(gòu)成：主語(yǔ)＋was/were＋動(dòng)詞的過(guò)去分詞。Somenewcomputerswerestolenlastnight.昨天晚上有幾臺(tái)新電腦被盜了。Summary:Whathaveyoulearnt?1.句型whenwasthecarinvented?
