B

解析

试题分析：句意:--你终于来了，什么事使你用这么长的时间？--对不起，我来晚了，但是你知道我找到你的家有多困难。这里是感叹句型，被感叹的是名词difficulty，所以用的是what，这里是短语have difficulty （in）doing，in可以省略，故选B。
点评：本题难度适中。固定短语的考查是近几年高考的热点，不仅在单选里，还出现在完形短文改错中。需要考生平时牢记它们的用法及意义。这里考生容易误选C。
即学即练: I always have difficulty ______ new words.
A. pronounced            B. pronouncing
C. to pronounce          D. for pronouncing
解析：B。句意：对新单词的发音我总是有困难。
