这类例子大多为假设，泛泛而谈，语言空洞，很难有说服力。事实上，当我们在阅读地道的英美人的文章时，我们就会发现，英美人的文章中是充满了细节的，而这才是中国学生在进行论证时最缺乏的。
例如 speed and comfort中描述坐火车的无聊时就运用了很多细节：Train compartments soon get cramped and stuffy. It is almost impossible to take your mind off the journey. Reading is only a partial solution, for the monotonous rhythm of the wheels clicking on the rails soon lulls you to sleep. During the day, sleep comes in snatches. At night, when you really wish to go to sleep, you rarely manage to do so. If you are lucky enough to get a sleeper, you spend half the night staring at the small blue light in the ceiling or fumbling to find your ticket for inspection.Inevitably you arrive at your destination almost exhausted.
在这段当中，几乎没有纯粹的说理，而是一直在描述一个我们感同身受的场景，细节颇多，让人一看就很有认同感。这样一种细节的堆砌无疑是很多说服力的，点滴之间，便让人信服。
