What we have to admit is that never in the past thirty years so greatly as today.
A. has China changed
B. China has changed
C. did China change
D. China had changed

(答案→)A. has China changedB. China has changedC. did China changeD. China had changed解析：部分倒装中考查较多的有：(1) 含有否定意义的词never，seldom，little. hardly，not，scarcely，nowhere，by no means(决不)等置于句首时。(2)以only修饰作为状语的副词、介词短语或从句，且放在句首时。　注意：only 修饰状语从句放在句首时，状语从句不需要倒装，只能倒装主句部分。(3)当so置于句首意为“也如此”，neither，nor置于句首意为“也不”时。当so表示对前句内容的肯定和附和，译作“确实，正是”时，用自然语序。(4)当not only…but also, so／such…that, not… until, no sooner… than, hardly… when等连词置于句首时。(5)在as引导的让步状语从句中(名词／形容词/副词／动词+as+主谓结构)。(6)虚拟语气的条件状语从句省去 if时，须将were，had，should提到句首构成倒装句。(7)频度副词often, always, once, now and then, every other day, many a time等放在句首时。(8)为了使句子保持平衡，为了强调表语或为了使上下文紧密衔接时，常使用倒装语序。本题中的否定词never in the past thirty years放在了句首，后面使用部分倒装的形式。句义：我们不得不承认的是在过去的30年里，中国从来没有像现在这样产生巨大的变化。本句的时间状语in the last thirty years通常与现在完成时连用。故A正确。

和我的回答一样，看来我也对了
