如果要我们分辨一个西瓜与一粒芝麻的重量,你会很轻易得出正确结论。有一个“脑筋急转弯”题目——一斤棉花和一斤铁哪个重?这个问题,却在一时间难倒无数英雄。究其原因,可能是铁的用处更多,给我们的帮助更大,在我们心中,铁重。或者,铁总是给人沉重之感,我们理所当然地认为铁重。由此看来,有些时候,轻和重并不如人们想象中那般容易区分,最典型的莫过于环境与经济的关系。 If you want to tell us the weight of a watermelon and a sesame seeds, you will easily draw the correct conclusion. There is a “Riddles ” topic - a pound of cotton and a pound of iron which heavy? This problem, but for a time difficult to countless heroes. The reason may be more useful for iron, to our greater help, in our hearts, heavy iron. Or, iron always gives a heavy feeling, we take for granted that iron heavy. From this, in some cases, light and heavy are not as easily distinguishable as people think. The most typical one is the relationship between environment and economy.
