| Last week I read a report on a charity show. The aim of the show was to 1 money for the poor children who were out of school 2 their families didn' t have 3 money for their children. Many famous pop stars 4 the charity show, such as Jackie Chan and Lin Junjie. The stars didn't 5 any pay (报酬). They did that for free. There were a lot of performances, including singing and dancing. The audience were 6 excited that they clapped their hands (鼓掌) from time to time. Of course, the show was 7 . All the people followed the 8 examples. They gave their money to the charity show. Both the ticket money and the donated money would be sent to the poor areas and some of the poor children would get back to school. Now many charity shows 9 in our country, not only to support education in poor areas but also to help people in trouble. I hope the whole world will become more and more beautiful 10 people's help. | |||
