3. 语法小贴士(本课语言重点:被动语态):
① 语态:英语动词有主动语态与被动语态。主动语态表示主语是动作的执行者(Peter invented the radio.);被动语态表示主语是动作的承受者(The radio was invented by Peter.)。
② 构成:be + 及物动词的过去分词(done)。be 动词随人称与时态变化,过去分词不变。
③ 一般现在时的被动语态:am / is / are + done。如:A mini-camera is connected to the front of the glasses.
④ 一般过去时的被动语态:was / were + done。如:A radio message was sent across the Atlantic Ocean in 1901.
⑤ 主动变被动三步:①主动句的宾语变主语;②谓语变 be + 过去分词(be 的时态与原句一致、人称与新的主语一致);③主动句的主语变成 by 短语(可省略)。
⑥ 含情态动词的被动语态:can / must / should + be + done。如:Toys, chairs and tables can all be made by the 3D printer.
⑦ 不及物动词(happen, appear, rise 等)与部分起系动词作用的词(look, sound, smell, taste)没有被动语态。
⑧ 双宾语动词变被动:以“人”作主语时保留宾语,以“物”作主语时需补 to / for。如:A prize was given to him.(to 不可省)
4. 被动语态构成速记表:
时态 | 构成 | 例句 |
一般现在时 | am / is / are + done | A mini-camera is connected to the front of the glasses. |
一般过去时 | was / were + done | A radio message was sent across the Atlantic Ocean in 1901. |
含情态动词 | can / must / should + be + done | Toys, chairs and tables can all be made by the 3D printer. |
