Question

一般过去式的被动语态

Answer 1

一般过去时的被动语态的基本结构是：be动词的过去式（was、were）+动词的过去分词+其他形式。其表示过去某一时间的被动动作或过去经常性、习惯性的被动动作。

1、肯定句

结构：主语＋was/were＋动词过去分词＋其他

A new shop was built last year.

去年新建了一家商店。

2、否定句

结构：主语＋was/were＋not＋动词过去分词＋其他

The  computers were not bought last week.  

上周没有买电脑。

若句子中含有双宾语，在改为被动语态时，遵循以下方法：

1、将间接宾语转化为句子主语。

She gave the little girl some flowers．

她给了那个小女孩一些花。

2、将直接宾语转化为句子主语，此时间接宾语前通常加上介词to或for。

例：They bought the children many good books.

他们给那些孩子买了许多好书。

Answer 2

一般过去时的被动语态，就是用动词be的相应单词was，were+动词的过去分词。
例如：I took a book to school. ---- A book was taken to school by me.
he carried a heavy box. ---- A heavy box was carried by him.
You made some mistakes in the exam. ---- Some mistakes were made by you in the exam.
