在商店里买布,特别是花布,为了看准颜色,往往把布拿到太阳光下观察,而不是在日光灯下看,这是为什么?

答案

因为太阳光中的色光最全,照在花布上反射的色光就是花布的各种真实颜色,而日光灯的色光不全,偏重于紫光,不管什么颜色在日光灯下都有一点灰暗的调子,所以为了看准颜色,往往把布拿到太阳光下观察,而不是在日光灯下看.

If someone says to you: “ Give me five”, do not search your pocket to get five yuan! It will make others laugh! The person’s not asking for your money, but your fingers.

In the US, “ give me five” or “ give me the high five” is a popular gesture ( 动作 ). You can see it often in films or on TV. It means the clapping ( 拍  ) of each other’s raised right hands together.

People do it when they meet for the first time or something happy happens. For example, a student has good marks in exams or wins a lottery ticket ( * *   ). If a football team wins a game, the players will give high fives to everyone around to celebrate.

This gesture may come from the old Roman gesture of raising the right arm for the king. This showed that the person raising his arm did not have a sword ( 剑 ) in his hand.

Why not try to give the high five to your friends?
