2027届高考英语一轮复习语法考点8被动语态

高三英语语法复习 考点8被动语态 八大被动结构·无被动动词·主动表被动→综合100题 语态问题只有一句话：主语是动作的发出者→主动；主语是动作的承受者→被动。 一、一眼识别 · 主语是物，后面给的动词是及物动词（如build,make,publish,design,award）→多半被动。 · 句子里没有by短语也没有宾语，但意思上需要宾语→被动。 · 空格后有by→几乎必被动。 二、八大被动结构 时态 被动结构 例句核心 一般现在 am/is/are done is regarded as 一般过去 was/were done was built in 1990 一般将来 will be done will be held tomorrow 过去将来 would be done would be finished 现在进行 am/is/are being done is being repaired 过去进行 was/were being done was being discussed 现在完成 have/has been done has been recognized 过去完成 had been done had been damaged 情态动词 情态+be done should be taken/can be done 三、没有被动语态的动词/短语（只能填主动） 表拥有、花费：have,cost,lack,own 表归属、适配：belong to,suit,fit 表自然发生：happen,take place,break out,occur,last,run out,come true,come out 表构成、追溯：consist of,date from/date back to,make up（组成时） 系动词：be,look,sound,smell,taste,feel,seem,appear,become,remain 四、主动形式表被动意义（高考高频陷阱） 结构 用法 例句 主语为物+sell/wash/write/read/cook+well/easily 说明事物性能 The novel sells well. 感官系动词+adj. smell/taste/feel/look/sound/prove The plan sounds practical. won't/can't+open/lock/move/close 物品属性 The door won't close. need/want/require/bear+doing =to be done The house needs repairing. be worth doing 只用主动 The film is worth watching. be to blame 应受责备（主动表被动） Who is to blame? 口诀：被动三问——"谁做的？"（不知道/不重要）→"谁被做的？"（主语被做）→"这动词能不能有被动？"（不能就填主动）。 训练题库（100题） 1.
