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：

Anna really wanted to do something significant for her school before she went to college. But she couldn't think of anything meaningful that would influence the lives of her schoolmates.

One day, Anna saw a girl sitting by the school pond crying. Anna went up to her and said, "Are you okay? Is there anything I can do to help?" Anna found out that the girl was in her first year and was having trouble coping with her schoolwork. Then, Anna had an idea. She would start a tutoring group where seniors could help juniors who were struggling in their subjects.

Before long, many seniors volunteered to join Anna's tutoring group. Soon, Anna also started other support groups like "I'm not Alone" which provided counseling for students whose parents had been divorced and "Crime Fighters" where students helped prevent theft. Anna was happy that she made a difference in her peers' lives. She was showered with flowers of appreciation from her friends at her graduation!
