One way of deciding what to do when you have difficulty in choosing the best course of action is to toss a coin. 当人们遇到困难不知选什么行动方案最好的时候，一个方法就是扔硬币来决定干什么好。
注：该构造中的介词in有时可以省略。
如：I had difficulty carrying out the plan. 我执行这项方案有困难。
She was having great difficulty getting her car out, and so I had to move my car to let her out. 当时她正无法把车子开出来，所以我就移开了我的车子让她开出来。
另外，假设difficulty后没有出现动名词，而是接名词，那么要用with sth。
如：Some people had difficulty with the lecture, but most understood. 有些人听讲有困难，但大局部人听懂了。
