许多人对蛇都有一种与生俱来的恐惧感,在他们眼里,蛇也许是地球上最可怕、最令人厌恶的动物之一。这些“冷血杀手”虽然没有四肢,却能上天入地、无处不在,既能在崎岖不平的陆地上迅速移动,如履平地,也能在温暖的水域中畅游,还能在枝叶繁茂的树木中自由穿梭甚至滑行,四肢对它们来说的确有些多余。 Many people have a natural sense of fear of snake, in their eyes, the snake may be one of the most horrible, most repulsive animals on earth. These “cold-blooded killers,” without their extremities, are capable of moving into the sky and everywhere, moving rapidly over bumpy land, leveled, swimming in warm waters and lush foliage The trees are free to shuttle or even glide, and limbs do have some excess to them.
