my mother gave me a present for my birthday改为被动语态

Question

要说明为什么！

Answer 1

为你解答。
My mother gave me a present for my birthday. （改为被动语态）
A present was given to me by my mother for my birthday.
或 I was given a present by my mother for my birthday.
解释：give是接双宾语的，所以这句有两种改法。一种是物（礼物）作主语，一个是人（我）作主语。时态是过去时，主语都是单数，所以谓语结构由was加上过去分词given构成。原来的主语由by来表示。

Answer 2

A present was given to me from my mother for my birthday
因为被动，宾语变主语，主变宾，谓语改被动，其他相应改。
