Question

【题目】—How about your travel?

—You can hardly imagine what difficulty we have had ______ the vast desert.

A．exploring B．explored C．to explore D．explore

Answer 1

【答案】A

【解析】

试题分析：考查动名词的用法。句意：—— 你的旅行怎么样？——你很难想象我们在探索浩瀚的沙漠时所遇到的困难。have difficulty (in) doing sth.做某事有困难，这里将difficulty提前，空中应用动名词形式。故选A。
