主动语态表示主语是动作的执行者。巧记为：主动、主动、主去动。

例如：ManypeoplespeakEnglish.

谓语speak的动作是由主语manypeople来执行的。

被动语态表示主语是动作的承受者，即行为动作的对象。巧记为：被动、被动、主被动。

例如：Englishisspokenbymanypeople.

主语English是动词speak的承受者。把下列句子变为含被动语态的句子：1.Mr.Licorrectsthestudents'homeworkeverymorning.Thestudents'homeworkiscorrectedbyMr.Lieverymorning.2.Peopleplaybasketballallovertheworld.Basketballisplayedbypeopleallovertheworld.主语主语谓语宾语谓语宾语语法点击一般过去时的被动语态1.概念：一般过去时的被动语态表示主语是过去某个动作的承受者。2.构成：主语＋was/were＋动词的过去分词。Somenewcomputerswerestolenlastnight.昨天晚上有几台新电脑被盗了。Summary:Whathaveyoulearnt?1.句型whenwasthecarinvented?
