英语的被动语态格式是什么!

基本被动语态的格式是：be动词+及物动词的过去分词,但是“be＋及物动词的过去分词”结构不一定都是被动语态,有些动词（如 be,feel,look,seem等）后面的过去分词已转化为形容词,用作表语表示状态.
My father gave me an MP4 as a present.
被动语态：An MP4 was given to me （by my father）as a present.
I was given an MP4 as a present by my father.
An MP4是主动语态的宾语,改被动语态要变成主语；介词要用by.
关于on的形式：主动：Tom gave me a present on my birthday.我生日那天汤姆送我一件礼物.
被动：I was given a present by Tom on my birthday.
A present was given to me yesterday.
关于to的形式：I hit him.(主)
He was hit by me.(被)
