     Jim lives in the country. He loves playing in the river near his old house, but now his father has a job

in a big city, so he moves there with his family.

      Their new house has a garden, but the garden is very small. So Jim isn't happy. "Is there a river

nearby?" he asks his mother on the first morning. His mother answers, "No, there isn't. But there's a nice

park near here, and there's a pool in it. We are going there this afternoon." Hearing it, Jim is happy now.

      After lunch, Jim and his mother go to the park. Jim wants to walk near the pool, but there is a sign

(牌子) before it. His mother reads it to him, "Be careful! This pool is dangerous (危险的). 367 people

have fallen (掉进) into it." Jim looks into the pool carefully, and he says, "But I can't see them."
