所谓改成被动语态的意思就是让句子中原来充当宾语的成分提出来做主语，然后把原来的谓语动词改成被动形式，即在原来动词前加相应的be动词，然后动词改成过去分词形式。
例如：主动语态：We（主） plant（谓） many trees（宾） along the road.
被动语态：Many trees（主，原句中的宾） are planted（谓，be+过去分词） along the road (by us（原句中的主，有时可以省略）).
一般来时主动改被动时原来句中的主语，即动作的发出者就可以省略了。

将下列句子变成被动语态
1 I was given a new desk as a present by mother.因为是双宾语，也可以说是：A new desk was given to me as a present by mother.2 个人觉得这句话表达有错 我觉得应该是 I made for my little brother a model ship last week可改成 A model ship was made for my little brother by me.3 Ann's homework must be finished by her first.4 I was often passed my pen by him.或 My pen was often passed to me by him.5 Were you bought the book you wanted by him？（这种句子不熟悉的话可先将它变成陈述句，再转变被动态，再变成一般疑问句）6He was seen to go into the classroom by me.（不带to的不定式，变被动态to要还原）7 Who is the old granny often taken care of by?8A ticket to a ball game could be given to him by you.或 He could be given a ticket to a ball game by you.9 Our classroom must be kept clean by us.10 The flowers should be watered every day by you.11 He may be invited to the party by them.12You will be asked some questions by the teacher.13 A coat is looked after carefully by Bill.14 Some money was left on the table by her.15 500 English words have been learned by me for two years.建议你先自己做，做完在对一下！这是学英语的基础！
如何改被动语态（任何形式的）如何把被动语态该会（任何形式）
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 of俯钉碘固鄢改碉爽冬鲸ten 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）。
Ps：我们老师就教了我们这么多，把被动改为主动只要反过来就行了。
