There were a lot of performances       singing and dancing. The audience(观众) were so      that they clapped their hands from time to time. Of course, the show was      .
All the people followed the stars’ example. They showed their generosity(慷慨)in        their money to the show. Both the ticket money and the donated money were soon sent to the poor areas and some of the poor children could get back to school.

I       the whole world will become better and better.
