One day, a student asked her teacher, "What is greed (贪婪)?" The teacher didn't answer her question (quick), but said, "Walk through the chocolate factory. Pick out the biggest chocolate bar (条,块) you can find. But there is rule: As you pass through the factory, you can't turn back"
The student went to the chocolate bar factory. As she walked, she saw a large chocolate bar.
She liked it, but she thought she might be able(find) a bigger one. Then she saw another bigger one. But again, she thought she could get an even bigger one she kept going. As she neared the end of the factory, she saw(few) chocolate bars, and none of them were as (large) as the earlier one. She started to feel sorry.
Finally, she (choose) nothing. She went back to her teacher without (something). The teacher told her, "You liked the first chocolate bar, but you kept looking a bigger one. So you didn't have the largest because you thought you could get a bigger one. That is called greed."
Sometimes, we let go of good (thing) in our life because we think we can find something even better.
