    What do you do on weekends? Some people like to stay at home, but others like to leave home and do other things. My friend, Tom works hard in a factory. He has a son and a daughter.

    On weekends, he usually does the same things. On Saturdays he washes his car and clothes. On Sundays, he goes to a farm with his family by car. His parents live there. The farm isn't very big, but there're often many things to do on the farm. The children help feed (饲养) the animals. There are many animals on the farm. You can see sheep, cows, horses and pigs. Tom and his wife help in the fields. At the end of the day, children are very tired and hungry. Tom's mother gives them a big meal. They are very happy.

    Helen Monson has always been interested in helping her community. Her first volunteer experience was for the American Red Cross when she was in high school. When she was a school teacher, she also found time to volunteer.

After she retired, she started volunteering to help the old. When her father was older, he was not able to see as well as he used to, which made her sad because he had always enjoyed reading.

    She decided it would be fun to read to elderly people in her community. She also helped one woman write her stories. Ann was almost 100 years old, and Helen wrote down information about her life when she visited Ann. She put the information in a book and got it published. Ann was very excited to share her life story with her children and grandchildren.

    One day Helen read an article in the newspaper about refugees (难民) who needed to learn English. Now, she meets once a week with Sahra, a 38-year-old woman from Somalia. Sahra is learning reading and writing skills. Helen gave Sahra a camera and asked her to take pictures of her daily life. She developed the pictures, and then asked Sahra questions about them. In the end they wrote a book together and used the photos in the book. This helped Sahra learn many new words about her everyday life.

    Helen says, “The most rewarding part of volunteer work is becoming friends with the people I help. They enrich my life as well as I enrich theirs.”

有一个温水煮青蛙的故事：把一只青蛙放进装有沸水的杯子时，青蛙会马上跳出来；但把青蛙放在温水中，慢慢加热至沸腾，青蛙则会舒适的游来游去，直至失去逃生机会，这个故事告诉人们“太舒适的环境往往蕴含着危险”之类的哲理。

但青蛙真的会被煮死吗？美国动物学家霍奇森就作了相关试验。他发现即使缓慢加温，到了一定温度以后，青蛙就开始躁动不安，试图逃离这个环境，如果装载的容器允许，青蛙还是会跳出来，所以，温水煮青蛙的故事根本就是蒙人的。
