Question

【题目】Not until he retired from teaching three years ago ______ having a holiday abroad.

A. he had considered

B. had he considered

C. he considered

D. did he consider

Answer 1

【答案】D。

【解析】句意：直到在三年前从教学上退休后他才考虑到国外度假。首先看到句首是Not until后我们知道，表达否定意义的连词短语位于句首时我们就要联想到运用部分倒装，因此可以排除A、C两项。再分析句子结构可知，本空所在的是主句部分，结合从句时态可知主句用一般过去时态。故选D。
