第02讲 过去进行时和过去完成时的被动语态
1.了解过去进行时和过去完成时的被动语态的解题方法与技巧。
2.进行过去进行时和过去完成时的被动语态真题训练。
(一)过去进行时的被动语态
1、 构成
肯定句:主语+was/were+being+动词的过去分词+其他
否定句:主语+was/were not+being+动词的过去分词+其他
一般疑问句:Was/Were+主语+being+动词的过去分词+其他?
特殊疑问句:疑问词+was/were+主语+being+动词的过去分词+其他?
2、 用法
1、 表示过去某一时刻正在进行的被动动作,即某事正在被做。句中往往含有表示过去的时间状语then,at that moment,at that time,at the time,this time yesterday等。句子没有时间状语时,需要根据上下文判断是否使用过去进行时的被动语态。

Corn was being harvested all autumn.
It was reported that changes were being considered.

否定句:主语+had not been +动词的过去分词+其他
一般疑问句:Had+主语+been+动词的过去分词+其他?
特殊疑问句:疑问词+had+主语+been+动词的过去分词+其他?

2.在 told,said,knew,heard,thought等动词之后的宾语从句中,若表示过去某一被动动作时,用过去完成时。
(1)They said the production costs of their company had been reduced.
