英语变被动句

陈述问：The wolves killed a young deer. 改为被动语态: A young deer was killed by the wolves.

主动语态→被动语态：1、找到该句宾语（必须是在谓语动词后的）,将它提到句子开头.2、用被动语态结构be+Vt过去分词构成句子.3、把原句的主语用by构成的介词短语带出,也可不加.eg：I finished my homework yesterday.→My homework was finished (by me) yesterday.特殊形式：1、部分Vi加上适当介词可当作Vt构成被动语态.eg：Parents look after their children carefully.→Children were looked after (by parents) carefully.2、联系动词没有被动语态.eg：The water feels warm.3、在主动语态中一些省略to的动词不定式改为被动语态时需加上to.eg：Teachers often make him stand outside.→He is often made to stand outside (by teachers).4、have、let等动词无被动语态.必要时,have可改为held,let sb to do sth可改为be allowed to do sth (被允许做某事）.

主动语态变为被动语态的方法将主动语态变为被动语态的方法可分为三步：第一步是把主动句的宾语变成被动句的主语；第二步是把主动句的谓语变成“be+过去分词”，be时态要与原句保持一致；第三步是把主动句的主语变为by的宾语，放在被动句的谓语之后，by短语可以省略。如：Mary broke the cup. 玛丽打破了杯子。The cup was broken by Mary. 杯子是玛丽打破的。扩展资料：被动语态的口诀：一般现在时、一般过去时用be +及物动词的.过去分词，be有人称、时、数变。完成时态have（has）done，被动将been加中间。一般将来shall（will）do，被动变do为be done。将来进行无被动，shall（will）be doing。现在完成时，被动 have（has）been done。现、过进行be doing，被动be加being done。情、助、有、是妥安排，一律随新主语变。否定助后加not，疑问一助置主前。主语恰是疑问词，直陈语序主在前。一般情助加be done，双宾多将间宾变。复合宾语宾变主，宾补、主补相应变

将一个英语句子改为被动语态时，先找出句子的宾语，将其作为句子的主语，把原谓语动词改为be＋过去分词（保持原句的时态）然后加上by＋原来的主语。如：They have caught a thief. (他们抓住了一个窃贼。）把宾语a thief 作主语，保持现在完成时。A thief has been caught by them. ( 一个窃贼被他们抓住了。）
