下面是个有趣的题目:“请用6根火柴棒摆出4个三角形,但不能将火柴棒折断。”如果你摆了6分钟还摆不出来,也不必心灰意冷,因为根据调查,大多数人都摆不出来。在公布答案之前,我们先聊一下跳蚤。跳蚤之所以叫跳蚤,因为它前进时不是走,而是跳,并且一跳可以跳到身体的近百倍高度。但德国柏林马戏团里的跳蚤却是用走前进的,甚至会表演拉车的特技(当然,观众要用放大镜来观赏)。 Here’s an interesting question: “Please put 4 triangles on 6 match sticks, but you can not break the match stick.” If you do not put it for 6 minutes, do not be discouraged, because according to the survey Most people can not figure it out. Before we announce the answer, let’s talk about the fleas. Fleas are called fleas, because it is not to go forward, but to jump, and jump to jump to the body nearly a hundred times the height. However, the fleas in the berlin circus in germany are walking forwards and even performing stunts (of course, spectators use spectacles to watch them).
