Question

【题目】—Thank goodness! You came here at last.

—You can hardly imagine what great trouble I have taken _______ your house.

A. to find B. finding C. found D. having found

Answer 1

【答案】A

【解析】

试题分析：句意：----谢天谢地！你总算来了。---你难以想象我费了多大劲才找到你家。A. to find 不定式表示将来、目的；B. finding现在分词表示主动正在进行；C. found过去分词表示被动完成； D. having found现在分词的完成时表示主动先发生。take great trouble to do固定短语，“”费力做某事，注意不要与have trouble（in）doing“做某事有困难”这个短语混淆。所以选A。
