不久前我和一个老朋友谈到这个问题。她教给我一个屡试不爽的应对失眠的妙方，那就是想象自己在反复地做某个细小的动作，直到她烦透了这种单调的生活，睡意也就悄然而至了。她最喜欢的方式是想象在墙上有一幅画挂得有点歪，然后去把它正过来。
【正确答案】：【参考译文】Discussing the question, some time ago, with an old friend, she gave me her never-failing remedy for sleeplessness, which was to imagine herself performing some trivial action over and over again, until, her mind becoming disgusted with the monotony of life, sleep drew the curtain. Her favorite device was to imagine a picture not hanging quite plumb upon the wall, and then to proceed to straighten it.
