Chuck Wall teaches management and human relations at Bakersfield College. He walked into class one day and told his students that their h 小题1: was to perform one act of random(任意的) kindness. His students did not understand the assignment(任务), but the professor would not answer their questions. He e  小题2:  his students to find it out for themselves.

One week later, the students entered the classroom excited to s  小题3:  their stories. One student told of distributing （分配，散发）blankets to the homeless, another had contacted a long, lost friend, and another student r   小题4: that he had helped a dog to find its owner. Students were energized(激励) by the homework assignment and wanted other people to be kind too. W  小题5:  the support of local businesses, the students made stickers to put on cars that invited people to do something k 小题6: for others. They sold the stickers and decided to donate the money to a center for the blind –not surprising as Professor Wall is blind.

Since then, s  小题7: kindness activities have been organized in schools all over the world. Many schools organize a Random Acts of Kindness Week, a 小题8: November 13, to celebrate World Kindness Day. Some schools use each day of Random Acts of Kindness Week to perform d  小题9:   kind acts, such as making a new friend, helping someone, doing community service, or raising money for a charity. Students learn to c  小题10: other people and think about how small actions can make the world a better place.
