表示现在正在进行的被动动作。

e.g:Mary is being interviewed now.My car is being repaired now. The disease is being studied

at present by scientist.The habitat of the

panda is being studied

at present .

现在正在研究熊猫的

生活环境。

3. 没有进行时的被动语态

一些表示状态、心理活动、拥有、存在等的

动词(和主动语态一样)一般不用进行时被动

popular.?In?other?words,?it?is?loved?by?more?

and?more?people.?4. 其他形式表示被动结构“be?+under/?in等

介词+名词”结构可代替进行时被动语态。如:The?city?is?under?attack?(?is?being?attacked?)?

at?the?moment.?

目前这个城市正受到进攻。The?bridge?is?under?repair?/?construction
