英语主动句改为被动句
英语主动句改为被动句：1首先我们要掌握主动句和被动句子的构成，先说主动句：是由主语+谓语+宾语+状语组成。
2被动句是由助动词be+过去分词的形式构成，过去分词保持不变，而所有的变化，都是人称，数，时态的变化，都体现在助动词be上。所以只要把不同时态的be掌握了，被动句就会变得简单。
3掌握了主动句和被动句的构成后，想要把主动语态变成被动语态就变得很轻松，在掌握以下步骤，就会更简单了.把主动句中的宾语转变为别动语态的主语。
4把动词改成be+过去分词。这一步很容易出错，注意时代动词的人称和数要随着新的主语（原来主动句中的宾语）而变，同时be动词的时态按照原来主动语态的时态保持不变，be动词后面的过去分词就是原来主动语态句子中的动词的过去分词。
5原主动句子中的主语，如果需要就放在by后面以它的宾语形式出现（因为by是介词后边需要跟宾格介词的宾语）以指明做事的人或者物，如果没有必要可以省略。
6其它成分 定语，状语不变。

英语主动句改被动句怎么改
由于楼主没给例题
所以我这里把一些比较常见的通用的方法罗列一下：
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）。
