Question

Only then ________how much damage had been caused.

A．she realized	B．she had realized
C．had she realized	D．did she realize

Answer 1

D

解析试题分析：句意：就在那时她才意识到已经引起多么大的伤害。Only then放在句首句子应该用部分倒装，根据had been caused可知realize应该用过去式，故用D。
考点：考查倒装的用法。
点评：本题难度适中。倒装句是高中阶段必须掌握的语法项目，它分为部分到装和全部倒装，情况复杂，需要考生熟记它们的用法。
即学即练：_______by keeping down costs will Power Data hold its advantage over other companies.
A. Only     B. Just    C.Still    D. Yet
解析：A。only置于句首修饰状语时，句子要用部分倒装。B、C、D三项无此用法。
