现在进行时的被动语态表示此时此刻某事正在被做。
The sports meeting is being held in our school.
我们学校正在举行运动会。

例1单句填空
Look!The baby (take)care of by her aunt.
思路分析:粉解题应从语境和主被动关系入手。
解析:从Look可知,句子用现在进行时态,而The baby 和take care of之间是被动关系,所以填is being taken。
答案:is being taken
2. 现在进行时的被动语态的否定句式为:主语e(am/is/are)tot being done+其他。
Some animals are not being protected well enough.
一些动物目前没有被很好地保护。
My room is not being cleaned by my mother.
我的房间目前没有被母亲打扫。
3. 现在进行时的被动语态的一般疑间句需将am/is/are提到主语的前面。
Is this bridge being repaired now?这座桥现在正在被修缮吗?
三、注意
四级分数换算1. “be being done”中的动词be应随主语作相应的变化。
2. 将现在进行时的主动语态变为现在进行时的被动语态的关键是把be doing变为be being done。
①The students are cleaning the classroom now.
→The classroom is being cleaned by the students now.
现在学生们正在打扫教室。(are cleaning 变为is being cleaned)
②The boy is counting some eggs.
→Some eggs are being counted by the boy.
这个男孩正在数鸡蛋。(is counting变为are being counted)
特别提示:
i am a student
(1)注意不可遗漏being。
现在进行时的被动语态表示说话时正在进行的一个被动的动作,强调主语是动作的承受者,其构成为“主语+am/is/are+being+动词的过去分词+其他”。
如果我们把being漏掉,就成为一般现在时的被动语态或系表结构。如:Look!The children are being taken care of by their aunt.
interest的用法
看!孩子们的婶婶正在照顾他们。
例2 单句填空
Be quiet!I want to listen to the latest news about the result of NBA, which (broadcast)on the radio.
思路分析:解题要从语境和主被动关系入手。
解析:题干中的“Be quiet”表示事情正在发生。broadcast与the latest news 是被动关系,故用现在进行时的被动语态。
旋窝答案:is being broadcast
(2)注意不可忽视“现阶段”。
现在进行时的被动语态表示目前这一阶段正在进行的一个被动的动作。如:Many interesting experiments are being carried out the days.
这些天正在进行许多有趣的实验。
(3)注意现在进行时的被动语态有时也可以表示将来。美国大选日期
现在进行时的被动语态有时可表示按计划或安排将要进行的一个被动的动作(此种用法仅限于少数及物动词)。如:
A party is being held tonight.
今天晚上会有一个聚会。
(4)注意没有现在进行时的被动语态的动词。
一些表示“状态、心理活动、拥有、存在等”的动词,一般不用现在进行时的被动语态,而常用一般现在时的被动语态。如:
Xiao Wang, come here. You are wanted on the phone.
董事长英文小王,过来这边。电话里有人找你。
(5)注意“be+under/in/on+名词”结构可表示现在进行时的被动语态的含义。如:zm
The problem is under discussion (is being discusd)at the meeting.
这个问题正在讨论中。

单句填空
1. The children (look) after by an old man now.
2. The material (study) at the rearch centre at prent.
3. Wait a minute. The dishes for the dinner (cook) in the kitchen.
4. They are living with their parents for the moment becau their own hou (rebuild).
5. The church tower which (restore) will be open to tourists soon. The work is almost finished.
答案:
corollary1. are being looked 句意:现在这些孩子正在被一个老人照顾着。句子中有时间状语now,而且The children和look after之间是被动关系,要用被动语态,所以答案应该填are being looked。
instructor2. is being studied 句意:这个物质正在研究中心被研究。时间状语是at prent,和现在进行时连用,而且The material与study之间是被动关系,所以答案填is being studied。
3. are being cooked 句意:等一会儿。晚饭吃的菜正在厨房里做呢。从句意可知,饭被做是正在发生的事情,那么答案应该填are being cooked。
4. is being rebuilt句意:目前他们与父母住在一起,因为他们自己的房子正在被重建。考查动词的时态和语态。根据主句的时态和意思可知becau引导的从句应用现在进行时,又因为hou和rebuild之间是被动关系,所以用现在进行时的被动语态。
5. is being restored 句意:那座正在被整修的教堂塔很快就会对游客开放。整修工作几乎已经完成。考查动词的语态和时态。由语境可知,the church tower是“正在被整修”,因此用现在进行时的被动语态。
