问题描述：
My best friend Alice wants to work in the big hospital which____still_____
A is building
B has been built
C is being built
D will be built
那个.为什么选C.
B为什么不能选.
还有.什么时候会用到being done?
答
因为有still，“仍旧”，如果是B的话，现在完成时就表示建完了，但是因为有still，表示还没有建完，是仍在建设中，所以用现在进行时，being done是进行时的被动
例:The coat is being washed.
(某人)正在洗衣服.
答
你理解看看就知道了，如果已经建好了语句还需要说明吗？所以根据题意理解，医院还未建好的。由于被动，而且是正在建，所以只能选C。
另外，被动进行时的使用，一般都是事物正在被做，还未结束就可以用到being done，还，作为开头也可以用being done。
答
现在进行时的被动语态会用到being done比如 The house is still being built now 这栋房子还在被建造之中my best friend wants to work in the big hospital which is still being bulit我最好的朋友想去那所还在建...
