__________,for it happened a long time ago 原因?还有A为什么不对?

never, seldom, rarely, little, hardly, scarcely, no sooner, no longer, nowhere 等含有否定意义的副词若位于句首,则其后要用部分倒装.正常的语序就是he has thought little of it. 选项A是一般过去时,部分倒装要加助动词did,即little did he thought,另外变回正常语序A项成分缺少,也就是he thought little, little什么呢,不知道,所以不完整.
