One day, Jim asked his mother, “Is there a river near here?” His mother answered. “No, there isn’t, but there’s a nice park near here and there’s a pool(池塘) in it. We’re going there this afternoon.” Jim was very happy.
After lunch(午饭), Jim and his mother went to the park. Jim wanted to walk near the pool, but there was a sign(标记) in front of it.
