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 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.

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.
