Grammar：

现在进行时的被动语态 一? 基本结构

1. 肯定形式:―助动词be(am/is/are) + being + 过去分词‖,其中的is, am, are表明谓语动词的动作发生的时间为现在,并随着作主语的名词(代词)的人称和数的不同而使用其中的某一个形式; being done则表示正在进行的被动动作?例如:

The bridge over the river is being rebuilt. (这条河上的桥正在重建? )

2. 否定形式:把否定词not放在助动词be(am/is/are)之后,

即:―be(am/is/are) + not + being + 过去分词‖?如有多个助动词,则not放在第一个助动词之后?例如: The room is not being cleaned now. (现在没人打扫房间? )

3. 一般疑问句形式:把助动词be(am/is/are)移到句首并大写首字母,句末加问号,即:―Be(Am/Is/Are) + 主语 + being + 过去分词?‖?例如: Is your house being painted? (你的房子正在粉刷吗？)

4. 特殊疑问句形式:多数情况下,其构成方法是把疑问代词或疑问副词直接加在一般疑问句之前,具体情况可分为以下三种:

① ―疑问代词(作主语) + is being + 过去分词 + 其他?‖?例如: What is being done on the life of pandas? (正在采取什么措施保护大熊猫的生命? )

② ―疑问代词(作定语) + 名词 +is/are being + 过去分词 + 其他?‖?例如: Whose buildings are being built in the town? (城里正在建谁的楼房? )

③ ―疑问副词 + is/are + 主语+ being + 过去分词 + 其他?‖?例如: Where is the elk being studied by scientists? (科学家们正在哪里研究麋鹿呢? ) 二? 常见的四种基本用法

1. 表示现在时刻正在进行的被动动作,即谓语动词表示的动作此刻正在进行?这是被动语态的基本形式?例如:

The plan is being discussed at the meeting. (这个计划正在会上讨论? )

2. 表示现阶段正在进行的被动动作（但该动词在说话的瞬间未必正在进行）,即谓语动词表示的动作在目前阶段正在进行?例如:

A new school is being built in the town. ( 在这个镇上一所新学校正在建设。)

3. 表示一种经常性的被动行为,常和always, constantly等表示频度的副词连用?这种用法常常带有赞扬或厌恶的感情色彩?例如:

He is always being praised by the leader. (他总是受到领导的表扬? )

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. 与部分情态动词连用,表示对谓语动词正在进行的动作的一种推测?例如: The patient must be being examined. 三? 被动语态使用中的常见错误

1. 在现在进行时的被动语态中, am, is, are为第一助动词, being为第二助动词,缺一不可,且不可互换位置?例如:

The report is being written by one of the best students. (报告正由一名最好的学生写着呢。) The report is well written.(系表结构) ( 这个报告写得好。)

注:在文章标题?广告?新闻中使用此类结构时,常省略助动词be, 因此出现了being紧跟主语的情况?例如:

English teachers being wanted. 英语教师正在热聘中?(广告用语, being前省略了助动词are)

Snow being cleaned away. 积雪正在被清扫?(新闻报道, being前省略了助动词is)

2. take care of, look after, talk about, think of等短语动词用在现在进行时的被动语态中时,其中的介词不可省略?例如:

(还在考虑什么别的事情? ) 【误】 What else is being thought? 【正】 What else is being thought of?

3. 一些表示某种情况?状况或特点的动词如happen, appear, rise, become, wear, wash等,没有现在进行时的被动语态?例如: (这本书卖得很好? )

【误】 The book is being sold well. 【正】 The book sells well.

4. 现在进行时的被动语态不与表示时间或次数的状语连用?例如: (这块表修了两次了? )

【误】 The watch is being repaired twice. 【正】 The watch has been repaired twice.

5.现在进行时的被动语态也可以表示将来（此种用法仅限于少数及物动词）

A party is being held tonight. (今晚将要举行一场晚会。)
