1、专题十动词的语态和语气【考点一】各种时态的被动语态的构成被动语态是由“be + 过去分词”构成。被动语态的时态通过助动词be的变化来体现。助动词be必须与主语的人称和数相一致。常见的被动结构有(PP代表过去分词): 常用时态被动结构例句一般现在时am/is/are+PPEnglish is spoken by many people in the world. 一般过去时was/were+PPThey were given a warm send-off. 一般将来时will/shall be+PPA new bridge will be built over the river next y

2、ear. 现在进行时am/is/are+being+PPI think we are being followed. 过去进行时was/were +being+PPThey told me that they were being questioned by the police. 现在完成时have/has been+PPAll flights have been cancelled because of the fog. 过去完成时had been+PPHe asked if Mary had been sent to hospital. 含情态动词can/may/must be+PPSo

3、mething must be done to stop these accidents. 【图解】【考点二】主动语态变被动语态的方法主动语态变为被动语态时, 通常遵循以下三个步骤: (1)首先把主动语态的宾语变为被动语态的主语。(2)再把主动语态的谓语动词改为与其时态相对应的被动形式, 且与被动语态的主语保持人称和数的一致。(3)最后将主动语态的主语改为介词by的宾语, 置于句后。“by + 宾语”在句中常省略。如下图所示【注意】主动语态变被动语态的两个特殊点(一)含有双宾语的主动句变为被动句1. 常把间接宾语变为主语, 直接宾语仍然放在动词后面不变。2. 用直接宾语作被动句的主语时, 间接

4、宾语前有时要加介词to(在send, pass, write, give, show, bring等动词之后)或for (在buy, cook, make, order, choose等动词之后)。(二)含有复合宾语的主动句变为被动句1. 由形容词、名词作宾语补足语的句子, 变为被动语态时, 只需把宾语变为主语即可。2. 在主动句中, 不定式用作动词: 请(please)、听(hear, listen to)、观(look at, see, notice, watch)、感(feel)、使(make, have)、让(let)、助(help)等的宾语补足语时要省去不定式符号“to”, 但在变为

5、被动语态时要加上“to”。【拓展迁移】“主动变被动, 时态不用动”, 即助动词be 的时态要跟原主动语态中的时态一致。【语法串记】感使动词的主动与被动口诀感使动词好奇怪, to来to去费神猜。主动句里to拿走, 被动句中to回来。【练真题】一、被动语态的构成与用法(B)1.
