A boy went to the zoo with his family. He learned many things. He followed a guide. Guide said that dogs, cats, and cows breed quickly because they bear many offspring just one time. And ge went to the other area that is called dangerous place. Animals like foxes, lions, bears, and snakes may attack people because they like to eat people. So a little boy was afraid of them, and staied beside of the guide. He thought animals such as lions, tigers, snakes, and bears would be dangerous if they escape becaues they might attack people. His mother told him, ” People would protect all of things. Even though they are dangerous, people will treat well.” But the boy thought viruses like germs, HIV, and SARS spread easily, because people don’t protect these viruses. People couldn’t protect all of things. He just though, but didn’t tell his mother. It was not a party but just a going out, people wore diamonds, because they wnat to show their riches. His mother was not that kinds of person. He looked around the zoo and went to home.
