通俗地理解,腿是用来走路的,其实不尽然。请看下面几种动物对腿的妙用。残体自卫的腿:蚱蜢由于身体纤细,跳跃能力极强。按体重和跳跃距离相比,它的一跃相应于人跳过足球场的三分之二的长度。奇怪的是,当它被捉住时,为了逃命,自己会掉下一条腿,留下一条腿跳着逃跑,生物学上把这种现象称为“残体自卫”。 It is understood in the popular sense that legs are used to walk. It is not always true. Take a look at the magical use of the following animals on the legs. Legs of self-defense: As the body is slender, it is very strong in jumping ability. Its leaps correspond to the length of two-thirds of a person skipping a football field, as compared to weight. The strange thing is that when it is caught, in order to escape, he will drop a leg and leave one leg to escape and biologically call this phenomenon “residual self-defense.”
