句子的前半部分 "He is now working in a foreign firm" 表示现在时态,而后半部分 "but not until three years ago ________ to work outside the country" 表示过去时态。因此,需要使用过去时态的句子结构。
步骤 2:分析选项
A. has he started - 现在完成时,不符合句子结构。
B. will he start - 将来时,不符合句子结构。
C. did he start - 过去时,符合句子结构。
D. he started - 过去时,但不符合倒装结构。
步骤 3:确定正确答案
根据句子结构和时态,正确答案是 C. did he start,因为它是过去时态,并且符合倒装结构。
