①A modern school is being built in his hometown.(改为被动语态)

②A modern school isn't being built in his hometown.(改为否定句)

③Is a modern school being built in his hometown？(改为一般疑问句)

④Where is a modern school being built？(对句中的in his hometown进行提问)

三、现在进行时的被动语态的用法

1．表示此刻正在进行的被动动作，句中常用now，at the moment等时间状语。

A new film is being shown in the theatre now.Let's go to see it.

电影院里正在上映新电影呢，咱们去看吧。

2．表示现阶段正被进行的动作，但此动作在此时此刻不一定正在发生。

—Could I use your car please?

—Mine is being repaired by the workers.

——我能用你的车吗？

——我的车正在被工人们维修着。

3．表示一种经常性的被动行为，常和always，constantly，frequently等表示频率的副词连用，这种用法常常带有说话者的赞扬或厌恶的感情色彩。

I feel very puzzled that the goods in our shop are always being stolen.

我感到很迷惑，我们商店的商品老是被偷。

4．表示按计划或安排主语将要承受谓语动词所表示的动作。

②The plan to explore the South Pole is being made(make) these days.

③The question about where the factory is going to be built is being discussed(discuss) at the moment.

四、使用现在进行时的被动语态应注意的问题

1．不可遗漏being

现在进行时的被动语态中，be为第一助动词，being为第二助动词，缺一不可，且位置不可互换。此结构若缺少being，则就成为一般现在时的被动语态或系表结构。试比较：

The report is being written by the best student.

报告正在由一名最好的学生写着。

The report is well written.

这份报告写得很好。(系表结构)

2．不可遗漏介词

take care of，look after，talk about，think of等动词短语用于现在进行时的被动语态时，其中的介词不可省略。

Look！The children are being taken care of by their aunt.

瞧！那些孩子正由他们的姨妈照看着。

3．没有现在进行时的被动语态的动词

非延续性动词、表示存在意义、所属关系、静态特征的动词以及系动词不用于现在进行时的被动语态。

The book belongs to him.

这本书是他的。

4．“be(am/is/are)＋under/in＋n.” 结构

有时可相当于现在进行时的被动语态。

The bridge is in use.

＝The bridge is being used.

这座桥正在使用。
