2.一般过去时的被动语态的基本用法

用法示例

表示过去某一具体时间发生的动作，且句子的主语是谓语动词动作的承受者

Thehousewasbuiltin1990.

这所房子建于1990年。

讲述发生在过去的动作，且不知道动作的执行者

Hewashonoredwiththename“FatherofHybridRice”.

他被授予“杂交水稻之父”的称号。

①含有双宾语的主动句变为被动语态时，通常把指“人”的间接宾语变为主语，而指“物”的直接宾语则不变

Hegavemeabookyesterday.

Iwasgivenabook(byhim)yesterday

3.含双宾语和复合宾语的主动句变为被动语态的方法

②如果要把指“物”的直接宾语变为主语，则在间接宾

语前加to或for。

Ibroughthimsomefood.

Somefoodwasbroughttohim(byme).

③含有复合宾语的主动句变为被动语态时，要将其中的

宾语变成主语，宾语补足语不变。

JimaskedTomtogoforawalk.

Tomwasasked(byJim)togoforawalk.

④如果宾语补足语是不带to的动词不定式，主动语态变成被动语态时要加上不定式符号to。

WeoftenheardKatesingintheroom.

Katewasoftenheardtosingintheroom(byus).
