希望老师具体的讲一个这个语法点，不是太理解，希望有例句。谢谢！
解题思路： 现在进行时被动语态：表示现在正在进行的被动性动作。
解题过程：
现在进行时的被动语态
定义：现在进行时的被动语态表示此时此刻某事正在被做。
例如：
The sports meeting is being held in our school.
我校正在举行运动会。
Another bridge is being built over the Changjiang River.
长江上正在修建另一座大桥。
构成：be + being+过去分词
例如：
A number of Dongfeng trucks are being shipped abroad.
一批东风卡车正被运往国外。
用法：
1）“be being done” 中的动词be应随主语的单复数形式作相应的变化。
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)
注意：一些动词很少用于被动语态，因此这些动词在句子谓语用了现在进行时时也常没有被动语态。如：We are having supper now．一般不能变为Supper is being had now．。
最终答案：略
