Last Sunday I went to the park with my friends。There were many people in it though it was very hot。When we were walking in the park, we saw a little boy crying near the lake。 We asked him why he was so sad。He said nothing and pointed to the lake。 We were puzzled and surprised。"What's wrong? Who is in the water? Your mum? Your dad?" The boy didn't answer。 We wanted to help him, but we can't。 After a while, a puppy came out of the water。The boy picked it up and smiled。 中文解释:昨天我和我的朋友们一起去了公园。虽然天很热但那里还是有许多人。当我们正漫步在公园里时,我们看到一个小男孩正在湖边哭泣。我们问他为什么这么难过。他什么也没说只是指着那个湖。我们都很迷惑和惊奇。"发生了什么?谁在水里?你的妈妈?你的爸爸?"男孩没有回答。我们想去帮助他,但我们无能为力。过了一会儿,一只小狗跃出水面。那个男孩捡起它笑了。
