He opened the door. We will repair this watch in two days. 被动语态表示主语是动作的承受者。 例如：English is spoken by many people. The door was opened. This watch will be repaired by us in two days. 被动语态构成：be+p.p. 语 态 分 类被动语态的定义： 语态是动词的一种形式，用以表示主语和谓语之间的关系。当主语是谓语动作的执行者，则为主动语态；当主语是谓语动作的承受者，则为被动语态。 被动语态由助动词be + 过去分词构成，时态通过be表现出来。一般现在时——— am／is ／are + v.p.p.一般现在时的被动语态：A recorder is used in our English class every day.Football is played all over the world.Cameras are used for taking photos.　被动语态的构成：be +vt.p.p..A knife is used for cutting. A knife is not used for cutting. Is a knife used for cutting ? Yes, it is . No, it isn’t.一般过去时的被动语态：A man-made satellite was sent up into space last year.被动语态的构成：be +vt.p.p.一般过去时——— was／were +v.p.p.The flowers were sold out yesterday.The flowers were not sold out yesterday.Were the flowers sold out yesterday ?Yes, they were . No, they weren’t.一. 何时使用被动语态 1. 不知道谁是动作的执行者或没有必要指出动作的执行者时: ① Paper is made from wood. ② He was wounded in the fight. 2. 需要强调动作的承受者时 ① Books and newspapers in the reading room mustn’t be taken away. ② He was awarded first prize in that contest. 3. 为了使语气婉转, 避免提及自己或对方而使用被动语态, 或由于修饰的需要, 使用被动语态, 使句子得以更好的安排。 ① The construction of the new lab must be completed by the end of next month. ② Electricity is used to run machines. 二. 被动语态的构成 1. be + done可以是被动语态, 也可以是系表结构形式。被动语态中, done可以带by短语, 而系表结构中done相当于adj.不带by短语。 许多verbs (broken, interested, shut, worried), 既可以用做adj., 也可以在被动语态结构中做过去分词, 句中如果有by, 通常是被动语态。① I was worried about you all night. (表状态) I was worried by mosquitoes all night. (表动作) ② The glass was broken by Jack. (表动作) The glass is broken. (表状态)三. 不同形式的被动语态 1. 含有直接宾语和间接宾语的主动结构, 变为被动时可将其中一个宾语变为主语, 另一个不动。一般是主语结构的间接宾语变为被动的主语。He showed me his pictures.I was shown his pictures by him. His pictures were shown to me by him. Aunt made me a new dress. I was made a new dress by aunt.A new dress was made for me by aunt.2. 含有复合宾语的主动句, 宾补不变。 (1) 将宾语变为主语, 宾补不变。 They call her XiaoLi.
