关于pull的选择题
The dangerous building ____now.
A.is being pulled down B.is been pulled down
C.is pulling down D.was pulling down
个人感觉貌似A,C都可以吧?课本上是有句话是The windows from old buildings around the town that were being pulled down.
我也没想明白这个地方为啥要用个being.were pulled down不可以吗?were being ...是个什么用法?
请解决下这两个问题

.我来解决你的问题
①硬性回答：选A,不能选C.因为房子是被推倒的,不是自己倒的.- -!(这是常识).所以符合被动的只有A.
B的错误在于根本没有"be+been"这种东西,只有has\have\had.
A、D的错误都在于根本不是被动语态,应该为"was/is pulled down".
②"be being done"这是被动的进行时态,译为“某事物正在被XXXX”.
③用"were pulled down"也可以,用这个就表示某事物已经被XXXXX.作者给你这个句子是根据作者表达的意思给的,课文这样写,就表示作者想说的是危房现在正在被推倒,况且还给了一个很重要的提示语“now".
④were being...就是用在主语是复数的情况下,例：
a old buiding is/was being pulled down.
many old buildings in this area are/were being pulled down.
以后做这种题主要看主语是人还是物,能主动发生这个动作吗?就比如这题,房子能自己倒吗?很明显,不能.所以只能是被推倒...
是被动语态的进行时态
