Never before ______ see such a terrible car accident on the road!
A. I have
B. have I
C. I did
D. did I
参考答案：D

表示否定意义的词never放在句首，要倒装，因此排除A和C选项;考查B选项，助动词用的have，与后面的动词原形see不一致，因此正确答案为D选项。
I was satisfied with her explanation, ______.
A. so my classmates were
B. so were my classmates
C. so my classmates did
C. so did my classmates
参考答案：B
解题思路：
用so, neither / nor引导句子表示与上文已经提到的肯定或否定意思一致时，so, neither / nor引导的句子要倒装，并且所用的谓语动词及其时态要与前面一句话的谓语动词及其时态保持一致，因此正确答案为B选项。
Hardly _______ on stage _______ the audience started cheering.
A. he had come / than
B. he had come / when
C. had he come / when
D. had he come / than
参考答案：C
解题思路：
hardly…when是固定搭配，表示“一……就……”;并且hardly意思是“几乎不”，表示否定意义，放在句首要倒装，因此正确答案为C选项。
Important _______ his discovery might be, it was regarded as a matter of no account in his time.
A. when B. until C. as D. although
参考答案：C
解题思路：
该句的意思是“______他的发明也许重要，在他那个时代，它被视为一件不重要的事情。”，根据句子的含义，可以看出前后两句话是转折的关系，因此选项部分应为让步状语从句，而在让步状语从句中，如果形容词或名词位于句首，则要用as或though，因此正确答案为C选项。
