但不是所有带有爪子的动物都能上树。老虎、熊等动物都有爪子,但它们不会爬树。这是因为它们的生活习性与猫不同,而且它们体格强壮,可以以凶猛的力量来捕食,同时抵抗敌人的伤害,而不需要爬树来躲避敌人的追击。其次,他们的身体重量都很大,一般的树不能承受这个重量,即使爬上去,树枝会被压断。因此,它们的爪子慢慢地变成只用来捕食,而不用于上树,老虎、熊等就不会上树了。而猫则不同,除了具有锋利的爪子外,身体轻快敏捷,同时,需要爬树来躲避敌人。因此,猫是爬树的能手。
But not all animals with claws can climb trees. Tigers, bears and other animals have claws, but they can't climb trees. This is because their living habits are different from those of cats, and they are strong enough to hunt with ferocious force and resist the enemy's damage at the same time, without climbing trees to avoid the enemy's pursuit. Secondly, their body weight is very large, and ordinary trees can't bear this weight. Even if they climb up, the branches will be broken. As a result, their claws gradually become only for hunting, not for climbing trees, so tigers, bears, etc. will not climb trees. Unlike cats, which have sharp claws, they are light and agile. At the same time, they need to climb trees to avoid enemies. So cats are good at climbing trees.
人们从动物身上学到了不少知识,利用鸟的飞翔的翅膀,人类制造了飞机,成功地在空中飞行;蝙蝠能发出超声波,并能根据回声判断环境的情况寻找食物,人们研究蝙蝠这种独特的本领发明了雷达;
