被动语态 The Passive Voice * 长沙京翰柑子园校区 何佳 一、主动语态与被动语态 主动语态表示主语是动作的 执行者。 被动语态表示主语是动作的承受者。 Model: Many people speak English.（主动语态） English is spoken by many people.（被动语态） 二、被动语态的构成：be + done（过去分词） １、一般现在时：am is done are ２、一般过去时：was done were . 3. 现在完成时: have /has been done 4. 过去完成时：had been done 5. 现在进行时: am/is/ are being done 6. 过去进行时：was/were being done 7.一般将来时： will be done shall 8. 过去将来时：would be done 9. 含有情态动词: can may must be done should have to 三、被动语态的用法 １、不知道谁是动作的执行者要用被动语态，如： This jacket is made of cotton. ２、没有必要指出谁是动作的执行者时要用被动 语态，如： English is spoken in Britain and America. ３、只需强调动作的承受者时要用被动语态，如： The bridge was built in 1990. 四、把主动句变为被动句的方法：在主谓宾结构中 １、把主动句的宾语变为被动句的主语，主动句 的主语变为by 短语（没必要时可省），如： Bell invented the telephone in 1876.
