问题补充：
My spoken English was poor and you can imagine what great difficulty I had myself understood.
A. make
B. to make
C. made
D. making
答案：
A. make
B. to make
C. made
(答案→)D. making
解析：句意：我的英语口语很差，你可以想象我让别人明白我的话所遇到的困难。此处解题关键是：have difficulty （in）doing sth这个短语。此处difficulty被提到前面去，I had myself understood.是定语从句，相当于I have difficulty in making myself understood.
