　　一个内科医生娶了一个女推销员，但是他们没有孩子。每次他看到商店里待出售的玩具娃娃，他就会非常焦虑地想要一个孩子。于是他想做一个实验克隆自己的孩子。他的妻子不同意他的计划，一方面她认为这是不合法的，另一方面这可能最后让他筋疲力尽。于是她想收养一个孩子。他的妻子劝他放弃这种思想。但他不改变自己的想法，义无反顾地进行了他的计划。结果他没有达到自己的目的，而且精神错乱了。

　　A physician married a saleswoman，but they had no children.Every time he saw a doll for sale in the shop，he would think of having a child with anxiety.So he wanted to perform a cloning experiment to have their baby.His wife didn't agree to his plan.On the one hand，she considered it illegal；on the other hand，it was possible for him to be worn out at last.So she wanted to adopt a child.His wife advised him to stop it，but he didn't transform his idea and pushed ahead with it.As a consequence，he didn't achieve his intention/goal and became crazy.
