By Sara 三、构成: 被动语态由“助动词be+及物动词的过去分词”构成即be+done 其中的助动词be有人称、数和时态的变化。 一般现在时态的被动语态各种句式如下： 句 式 构 成 例 句 肯定句 主语+am/is/are+及物动词过去分词+其他。 English is widely used all over the world 否定句 主语+am/is/are+not+及物动词过去分词+其他。 一般疑问句 Am/Is/Are+主语+及物动词过去分词+其他?

A watch was bought for me by my father yesterday. 例题： 主语 谓语 宾语 buy sb. sth. /buy sth. for sb. 给某人买某物 → → 主动语态转换成被动语态 By Sara 五、使用被动语态应注意的几个问题： 1.不及物动词（短语）没有被动语态如：happen,rise,appear,come out,take place等。 2.动词短语如talk about,pay attention to,look after,take care of等在变被动语态时其中介词不能省略。 3.在主动语态的句子中，感官动词和使役动词后面接省掉to 的不定式做其宾补时，在变被动语态时要加上。如see,make等（共10个词） 4.有些动词表示主语（多为物）的某种性质而非人为的原因时 做不及物动词，无被动形式。如：sell,write,ride,draw These books sell well. 5.连系动词如sell,taste,sound,look等用主动表被动。如： The food smells good. 6.当含有双宾语的动词变被动语态时，若间接宾语人做主语时，一切照旧； 若直接宾语物做主语时，则需在间接宾语前加to或for。如give,buy等。 六、历年考情分析 语法点 命题角度 命题方式 2021 2020 2019 2018 被动语态 一般过去时 完形填空 29 28 29 29 短文填空 66 68 67 链接真题： He and his friends returned home with the valuable things that __________by the robbers.(2021真题29） A.stole B.were stolen C.steal D.are stolen That was why he_______by the film dirtor.(2020真题28） A.invites B.invited C.is invited D.was invited By Sara 遥远的小岛上，住着一个倒霉蛋，它叫豆豆，那里的人只有三件事要忙，吃饭，睡觉，打豆豆。你看，它总是被打，还不知道是谁打的。 Doudou is always beaten by someone.
