Some kids went to a zoo with their teachers. One girl looked around many animals with them, and there are really cute dogs and cats, so, she stoppped in front of the dogs’ cage. As soon as she stopped, her teacher started to explain about them. The teacher said, dogs, cats, and caws breed quickly, so, they probably won’t exterminate. The little girl nodded her head, and approached them, and finally, she tried to touch them through a space between bars. At that time, one of zoo officers took her hand, and advised that it’s dangerous. He said, they can have viruse, and it can be spread, because viruse like HIV, SARS, and spread easily. She nodded her head again, and she went to see other animals. When she arrived snakes’ cage, she wondered why their cage don’t make of bars. The officer said that animals such as lions, tigers, snakes, and bears are danderous if they escape, so, they have to confine safely, and the girl asked to her teacher. Her teacher said, animals like foxes, lions, tigers, bears, and snakes may attack people, so, she have to be careful. At that time, her classmate said, the snakes skin’s color is similar to diamond’s color. The teacher just smailed. He said, the snake is poor, because people usually wear diamonds as shiny jewerly, so, people who is poor can kill snake, and make fake diamonds. It’s very sad story. The teacher and a little girl said the snake is protected, so, that never happened. The teacher thought kids are creative, curious, and pure.
