Snakes Are Hunters

捕猎能手--蛇

If you want to see really big snakes, a zoo is the place to go. You will never find these snakes near your home. Big snakes come from jungles and other hot parts of the world.

如果你想看真正的大型蛇，动物园是个好地方。这些蛇来自从林以及世界上某些炎热的地方。在你家附近可找不到它们的踪影。

You will also see small snakes and middle-sized snakes. But no zoo can show you every kind. All together, there are more than 3, 000 kinds of snakes.

在动物园你还能看到小型蛇和中等大小的蛇。但没有一个动物园能展示所有类型的蛇世界上总共有三千多种蛇。

Look at some snakes and you will see ways they are all alike. Each has a long body that is covered with scales. The scales overlap like shingles on a roof. Every snake has round eyes. The eyes never blink because a snake has no eyelids. Instead, each eye has a clear cover called a spectacle. The spectacle protects the eye.

仔细观察，你会发现这些蛇有很多共同点。每条蛇长长的身体上覆盖着鳞片。这些鳞片像屋顶上的瓦片一样交叠在一起。 蛇有圆圆的眼睛，却从不眨眼，因为蛇根本就没有眼皮。蛇眼上覆善着一层透明的膜,称为眼盖。眼盖能保护眼睛。

A snake has no legs. Even so, it gets around very well Many snakes can glide over the ground, climb trees, and swim. Snakes move in several ways. Most often you see one moving with S-shaped curves of its body. The curves push against rough spots on the ground, and the snake slides forward.

蛇没有腿，可照样能到处溜达。很多蛇可以在地面上滑行、爬树和游泳。 蛇有几种移动方式，最常见的是它的身体呈s形曲线移动。曲线推着地面上的粗糙点，蛇向前滑动。

Snakes are hunters. In the wild they find and catch other animals for food. This garter snake is hunting. It first senses that something is near when the frog hops. Snakes cannot hear sounds as we do. But they can sense the shaking of the ground when an animal hops or runs.

蛇是捕猎高手。它们在野外寻找并捕捉其他动物为食,这条束带蛇正在捕猎。当青蛙跳过时，它首先感应到附近有东西。蛇无法像我们一样听到声音，不过动物跑跳时，它们能觉察到地面的震动。
