问题 Only after half a year______to find the result of my experiment in his lab．

选项 A、I begun
B、I had begun
C、have I begun
D、did I begin

答案 D

解析本题考查倒装句型的用法。only, little, never, seldom, hardly等表示否定的短语放在句首时，句子要使用倒装句型。倒装句型分为全部倒装和部分倒装。本题属于部分倒装，结构为“倒装部分+助动词+主语+其余部分”。又如：0nly in this way can we solve the problem. 选项C的时态不符合句子中“after half a year”表示过去的时间要求。
