第二节：读写任务（共1小题，满分25分）

阅读下面的短文，然后按照要求写一篇150词左右的英语短文。

A father had three sons, but the brothers were always quarreling. Their father tried to make them good fiends, and called all his sons to him. He showed them three sticks and said, “I want to talk to you. Take these sticks and tie them together. Then try to break the bundle of sticks.” The oldest son tried with all his strength but he could not break it. Then the other two did the same, but neither of them could break it. “Now,” said the father, “untie the bundle and each of you take one stick and try to break it.” Either of them could break the stick easily. Then the father said, “My sons, when the sticks are bound together, it is very strong, and you cannot break it. But when they are united, you can break each stick easily. When you work together and help one another, you can become as strong as the bundle. But if you only quarrel and do not stand together, you will be broken as easily as these sticks.”
