With more and more rain falling, it's time for snakes to be active. Living in the city, it never crosses your mind that we might meet them face to face.
Most people are afraid of snakes. They may think snakes are dangerous and ugly. There are more than 2,000 kinds of snakes. Most of them live in mountains or forests, and in cities sometimes we can find them in grass or other dark places. Snakes can't walk or run because they have no legs or feet, but these long and thin animals can move very fast on their stomachs. Snakes usually have green, yellow or black skins, which make it difficult for their enemies to find them. In winter they hibernate in holes. They look for a hole to stay inside, in the ground, or in a rock or a tree. They do not wake up again until spring comes. Snakes feed on mice, frogs, bird eggs and so on.
Snakes play an important part in nature. We can make useful medicine with them. Without their help, the rodents (啮齿动物) will be out of control. But many of them are in danger of disappearing. Houses and buildings take up the land where snakes live. Many snakes lose their lives in traffic, and people often kill snakes for their skins or meat.
