Discussion&Summary The Present Progressive Passive Voice

结构

A 肯定句：

主语

+ am/is/are + being + 过去分词

B 否定句：

主语

+ am/is/are + not + being + 过去分词

用法

表示说话人说话时或现阶段正在进行的动作，经常和时间副词now (现在), right now (现在, 此刻), at present (现在, 目前),at this moment (此刻) 连用。

解析

主语和谓语动词之间是被动关系,而且动作正在进行。

1. Music is being taught by Miss Li now. 2. New functions are being added to the phone at present. 主动语态变被动语态

“三变”: 原句主语变为by短语, 宾语变为主语, 谓语由主动变为被动；

“三不变”: 原句意思不变, 原句时态不变, 原句主谓宾以外成分不变。

They are building nine parks. →

Nine parks are being built. →

How many parks are being built?
