一.被动语态的定义:
如果主语是动作的执行者(即某人做某事),便叫主动语态;
如果主语是动作的承受者(即某事被做),便叫被动语态。
e.g. I made a cake. (主动语态)

二.被动语态的结构:
被动语态的构成是be done
八种时态对应被动语态见下表:
一般现在时 一般过去时 一 般 将 来 时

现在进行时 过 去 进 行 时 过 去 将 来 时
am/is/are+ being +p.p. was/were+ being+ p.p. would +be+ p.p. was /were +going to+ be + p.p.

②将直接宾语变为主语,间接宾语用介词to或for引导。
His teacher gave him a dictionary. →He was given a dictionary by his teacher.

2.有些动词在主动结构中,后面接不带to的不定式,但如果改为被动,则需把省略的to加上,这类动词有hear, watch, make, help, let,see等
