选择题
Only when he failed in the final exam ____up his mind to study harder to catch up with the classmates ahead of him.
A．he made
B．he had made
C．had he made
D．did he make
答案
答案：D
题目分析：考查倒装句：only+状语置于句首，后面的句子用部分倒装，句意：只有当他期末考试失败，他才下决心更努力学校，赶上其他同学。说明用的是过去时，选D。
点评：值得注意的是only只有接状语时，才能用倒装句，接主语和宾语时，都不能倒装。
