请先看下面的图片，谢谢
　　
　　
　　
　　
　　这是格拉斯哥大学的菲利普先生和奥利维先生设计的奇异图片。
　　
　　These pictures were designed and developed by Mr. Phillippe G.Schyns and Aude Oliva of The University of Glasgow.
　　
　　你现在通过显示屏看到是：
　　
　　左边是一张生气的脸；右边是一张平静的脸。
　　
　　Now what you can see from your screen is :
　　
　　An angry face on your left, and a peaceful face on your right.
　　
　　请站起身来，从座位上退后几步，远处再来看这幅图片，告诉我你看到了什么？
　　
　　Please stand up and retreat few steps from your seat and watch from far, and tell me what you have seen.
　　
　　他们交换位置了！！
　　
　　THEIR POSITIONS HAVE BEEN SWAPPED!!
　　
　　所以，请不要总是相信自己的眼睛，也许你已被看到的东西欺骗了。
　　
　　我们可能从来都没有看到过事物的真实面貌，
　　
　　让我们保持怀疑精神吧！
　　
　　Therefore, please do not trust your eyes,sometimes. You may be deceived by them.
　　
　　You may not see the real faces (true picture?) as what they are supposed to be.
　　
　　Be doubtful, always!!
