知识目标：1.To understand the present progressive passive voice

2. To know the following words and phrases

二．自主学习：

现在进行时的被动语态。

一．基本用法：

当把现在进行时主动语态的句子变为被动语态时，往往在be动词后加上一个being来体现现在进行时，然后再把动词的现在分词形式变成过去分词来表示被动，即：be ( am / is / are )+being +done.

点津 ： be动词的选择要和前面的主语保持一致。

二．现在进行时的被动语态用用法。

1． 表示此时此刻正在进行的被动的动作。

My sister is now being interviewed.

我妹妹正在面试。

Yao Ming is now being treated in China.

姚明正在中国接受治疗.

2. 表示现阶段正在进行的被动的动作。

Many interesting experiments are being carried out these days.

这些天正在进行着许多有趣的实验。（说话时，并一定正在进行）

It is reported that the tomb in Henan is still being dug.

据报道河南的那个墓仍然正在挖掘中。

2． 表示反复进行的被动的动作。

Always , frequently, constantly等和现在进行时的被动语态连用表示反复进行的被动的动作，这种动词形式常用来表示赞扬或厌恶的感情色彩。

What makes me angry is that the goods in my shop are always being stolen.

使我生气的是我店里的商品总是被偷走。

If feel very surprised that the window of our classroom is frequently being broken.

我感到很吃惊的是我们教室的那扇窗户经常被打破。

三．使用现在进行时的被动语态要请注意的问题。

1． 不可漏掉being

若漏掉，则成为一般现在时的被动语态或系表结构。

瞧！那些女孩子正由他们的姑妈照看着。

Children are taken good care of at school.
