Never before______so rapidly developing as it is today.
A. has our country been
B. has been our country
C. our country has been
D. our country been has

选什么，最好翻译下

Answer 1

A.has our country been
这叫：部分倒装，即：具有否定意义的词放在句首时，主句的助动词（注意，是助动词，而非动词啊）提到主语前面。
楼主的句子中，Never 是个否定词被放到了句首，那么主句的助动词has就得提到主语our country 的前面。所以选A

Answer 2

A
never before前所未有的意思，放句首时要倒装，把助动词has放在主语前就行了。这句子正常语序是：Our country has never before been so rapidly developing as it is today.我们国家以前从未像今天一样发展如此迅速。
