英语的被动语态格式是什么！

Question

我想as，on，to，之类的词该怎么放。
比如My father gave me an MP4 as a present。
有两种改法，怎么改啊？...
我想问的是像to、as、on、in....诸如此类的介词怎么放？什么类型的词才是定语？

Answer 1

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)

Answer 2

be+过去分词
