     Snake meat is popular in restaurants. Some people think eating snakes is good for their health. But

these people don't know that snakes feed on mice and worms, so there are many parasites (寄生虫) in

snakes' bodies. They may be bad for our health. And we're sorry to see a butcher's (屠夫的) knife is

killing more snakes.

     An English newspaper says, "People eat about 1,000 tons of snakes every year in China. In

Shenzhen, sometimes people serve 10 tons of snakes on dinner tables in a day."

     If we continue to eat snakes, there will be a vicious circle (恶性循环). If people eat more snakes,

snakes are becoming fewer and fewer. But mice are becoming more and more, there will be few crops.

     This will make more people hungry. Who wants to see such a bad thing happen? So people must

stop eating snakes. To protect snakes is to protect ourselves.
