1、含有双宾语的主动句变被动句时，可分别将其中的一个宾语变为主语，另一个不动，但变间接宾语为主语的情况较多
主动句：
Tom gave me a present on my birthday.
我生日那天汤姆送了我一件礼物。
被动句：
I was given a present by Tom on my birthday.
A present was given to me on my birthday by Tom.
注意：
如果把直接宾语（指物）改为主语，则在间接宾语（指人）前加适当的介词：
一般说来，在 bring，give，hand，lend，offer，pass，sell，show，take，tell 等动词后，通常在间接宾语前用介词 to
而在 build，buy，cook，cut，choose，do，fetch，find，fix，get，keep，make，order , paint , play , sing 等动词，一般在间接宾语前用介词 for，此时for不可省略。
主动句：
Mother make me a new skirt.
母亲给我做了条新裙子。
被动句：
A new skirt was made for me.
主动句：
She lent me the very expensive coat.
她把她那件昂贵的外衣借给了我。
被动句：
The very expensive coat was lent to me．
另外，有时用间接宾语作主语讲不通或不习惯，则用直接宾语作主语
主动句：
Tom wrote me a letter.
汤姆给我写了一封信。
不说：1 was written a letter by Tom.
可说：A letter was written to me by Tom.
注意：
宾语从句一般不可作为被动句的主语
主动句：
He told me when the project would start.
他告诉我工程什么时候开始。
不说：When the project would start was told to me.
可说：1 was told when the project would start.
2、含复合宾语（宾语+宾补）的主动句改被动句时，一般把主动句中的宾语改为主语，而宾语补足语都保留在谓语动词后面为主语补足语
主动句：
We always keep the classroom clean.
我们总是保持教室清洁。
被动句：
The classroom is always kept clean.
教室总是保持清洁。
主动句：
We saw them playing football.
我们看到他们在踢足球。
被动句：
They were seen playing football.
有人看见他们在踢足球。
注意：
如果宾补是名词，变被动句时，不要误把宾补的名词作主语
主动句：
We called him an ass.
我们叫他傻瓜。
不说：An ass was called him.
可说：He was called an ass.
3、带有形式宾语it的句子也可变为被动句
主动句：
We consider it wrong to shout at children who make mistakes.
我们认为对犯错误的孩子大喊大叫是不对的。
被动句：
It is considered wrong to shout at children who make mistakes.
4、当主语句的主语是nobody，no one等含否定意义的复合不定代词时，被动句中将其变成anybody，作by的宾语，并将谓语动词变为否定的被动语态
主动句：
Nobody can lift this stone.
谁也拿不起这块石头。
不说：This stone can be lifted by nobody.
可说：This stone cannot be lifted by anybody.
