聪明人从旁人的错误中吸取教训，愚笨人则从自身的错误中吸取教训。

Wise men learn by other men's mistakes; fools by their own.

在过去二十年间进入大学的热潮中，贫困家庭聪明的孩子确实受到富裕家庭相对愚笨的孩子的挤压。

And in the stampede for university places that has taken place over the past 20 years, clever children from poor families have indeed lost out to dimmer peers from prosperous ones.

聪明人的手不做愚笨人所说的事。

The wise hand doth not all those the foolish mouth speaks.
