The sports meeting is being held in our school.我们学校正在举行运动会。
Another bridge is being built over the Changjiang River.长江上正在修建另一座大桥。
二、形式1. 现在进行时的被动语态的肯定句式为：主语+be(am/is/are)+being +done+其他。
如：The meeting is being held in our company.会议正在我们公司召开。
A number of Benz cars are being shipped abroad.一大批奔驰车正被运往国外。
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 taken2. 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。
