现在进行时表示现在或现阶段正在进行或发生的动作或存在的状态。现在进行时表示动作发生的时间是“现在”，动作目前的状态是“正在进行中”。现在和小编一起来看一下现在进行时的被动语态吧！
1、定义：表示此时此刻某事正在被做.
例如：
The sport meeting is being held in our school.
我校正在举行运动会.
Another bridge is being built over the Yangtze River.
长江上正在修建另一座大桥.
2、构成：be + being+过去分词
A number of Dongfeng trucks are being shipped abroad.
一批东风卡车正被运往国外.
3、用法：
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.
例1.The students are cleaning the classroom now.
→The classroom is being cleaned now.
现在学生们正在打扫教室.(are cleaning变为is being cleaned)
例2.The boy is counting some eggs.
→Some eggs are being counted.
那男孩正在数蛋.(is counting 变为 are being counted)
需要注意的用法有：
1、有些动词进行时的主动形式就可以表示被动的意思,常见的这些动词有: print, cook, fry, bake, burn, hang.
如：The house is burning. The meat is cooking.
2、在be + under / in/on +n. 的结构可以表示现在进行时的被动语态的含义。
The problem is under discussion now. = The problem is being discussed now.
3、与情态动词连用，表示对现在正在发生的被动行为的推测。
(1) John is not here .He must be being interviewed
(2) ---Do you know what Smith is doing?
---He is ill. He may be being examined by the doctor.
注意：助动词am/ is/ are和being缺一不可并且不可以颠倒顺序。
以上就是小编为大家整理的现在进行时的被动语态，对于现在进行时的考查，多以单选、句型转换或词语运用的形式考查学生在具体语境中灵活运用时态的能力，希望各位同学掌握以上用法后多加练习，巩固。 |
