先对比下面的句子：

1. He's a wolf in sheep's clothing.

（正确句子：他是披着羊皮的狼。）

He's a wolf in cheap clothing.

（“张冠李戴”的句子，sheep 故意错成cheap , cheap clothing 又是“廉价衣服”的意思。）

2. We go window shopping at Christmas.

（正确句子：圣诞节我们去逛商场，只看不买。）

We go widow shopping at Christmas.

（“张冠李戴”句子，window 错成widow , window shopping "只看不买"成了widow shopping “没有老公陪伴的购物”。）

3. Having one wife is called monogamy.

（正确句子：只娶一个妻子叫一夫一妻制。）

Having one wife is called monotony.

（“张冠李戴”句子，monogamy 错成monotony “单调”。 言下之意：娶一个妻子太单调，妻妾成群才多姿多彩？）

4. The flood damage was so bad they had to evacuate the city.

（正确句子：洪水造成的损失太严重，他们必须将城里人全部撤离。）

The flood damage was so bad they had to evaporate the city.

（“张冠李戴”的句子，evacuate 错成evaporate “蒸发”。）

5. A rolling stone gathers no moss.

（正确句子：滚石无苔。）

A rolling stone gathers no moths.

（“张冠李戴”的句子，moss “青苔”错成moth “飞蛾”。）

6. Good punctuality means not to be late.

（正确句子： 准点的意思是不迟到。）

Good punctuation means not to be late.

（“张冠李戴”的句子，punctuality 错成punctuation “标点符号”。）

这种“直把冯京作马凉”的张冠李戴，字里行间自有它一番幽默在。
