Ⅲ. Grammar
一般过去时的被动语态
e.g. These computers were made in America in 2022.
I wasn’t invited to Jack’s birthday party.
—Were the books written in English
—Yes, they were. / No, they weren’t.
When was paper invented
【注意】使用被动语态的情况
1. 不知道动作的执行者是谁。
2. 没有必要指出动作的执行者是谁。
3. 需要强调或突出动作的承受者时。
4. 句子的主语是动作的承受者。
5. 有些动词习惯上常用被动语态。
被动语态结构中应注意的几个问题
1. 主动句中在感官动词see、hear、watch、feel、notice等以及使役动词let、make、have等后跟省略to的不定式, 变为被动句时, 应加上不定式符号to。
e.g. Betty is often seen to help the old man with his housework.
2. “不及物动词+介词/副词”构成的短语动词，变成被动句时，要把它们作为整体看待，介词或副词不可与动词拆开或漏掉。
e.g. My grandpa is taken good care of in the hospital.
3. 含有双宾语的主动句变被动句时，可将主动句中的直接宾语或间接宾语变为被动句中的主语。
如果把主动句中的直接宾语(指物)变为被动句中的主语，则需在间接宾语(指人)前加适当的介词to或for。
常接to的动词有give, tell, lend, show, pass, hand等；
常接for的动词有buy, get等。
A ticket was given to me by Danny just now.
主动形式表示被动意义的情况
1. 动词sell, write, watch等作不及物动词，且它们的主语为物时。
e.g. This kind of dress sells well.
2. 某些系动词(如smell, look, taste, feel, sound等)描述某物特性时。
e.g. Dinner smells good.
3. be worth doing中，doing表示被动意义。
e.g. The book is well worth reading.
