The journey of a drop of water.
Du Yun was in the bathroom. The tap was on. As she brushed her teeth, she thought about going swimming with her friends and...
“Turn that tap off!” said an angry voice suddenly.
“You're wasting water!”
Du Yun turned the tap off and looked around, but there was no one there.
“Who are you ”
“I'm Dribble, and I'm a drop of water. Do you know where I come from ”
“From the tap ” asked Du Yun.
“Well, yes, but a few days ago I was in a cloud,” said Dribble.
“Then the wind pushed the cloud up a mountain. When the cloud cooled down, it started raining. I became one of the raindrops.”
“How did you come into my house then, Dribble ”
“I fell into a river and eventually ended up in a reservoir. Then I went to a special place. There people cleaned me and added some chemicals to me.”
“They cleaned you Why ” Du Yun asked.
“Because I was a bit dirty. Then I travelled through the pipes under the streets, and now I'm here,” Dribble explained.
“So is this the end of your journey " Du Yun asked.
"No. People will clean me one more time. Then I'll go into a river, and after that I'll return into the sea again.”
“Again ”
“Yes. My journey back to the cloud starts there. Remember not to waste or pollute me. I'm valuable.”
“I'm sorry, Dribble,” Du Yun came out of the bath.
Du Yun came out of the bathroom and rushed to her study. She wanted to tell her diary about this at once.
Understanding personification
Writers sometimes make animals or things seem human to make a story more interesting. In this story, the drop of water talks like a human being. This is called personification, and it helps the reader understand the writer's ideas more easily.
Read the story again to see how the writer uses personification.
作者有时会将动物或事物拟人化处理，以使故事更有趣。 在这个故事中，水滴像人一样说话，这是英语中的“拟人”手 法，有助于读者更容易理解作者的想法。
再读一遍故事，看看作者是如何运用拟人手法的。
