      CCTV held a charity show in May to raise money for the earthquake-hit areas in Sichuan. Many famous stars took part in the show. (A) They didn't ask for any pay, they all did it for free. There were a lot of performances like singing, dancing and cross-talks(相声 ). (B)The audience(观众) were so excited that they clapped(鼓掌) their hands all the time. Almost everyone was moved to cry by a lot of sad or moving stories. During the performances, they donated money to the disaster areas(灾区). The show was so successful.
      Besides that, many other stars are doing things for disaster areas in many ways. Kungfu star Jackie Chan and the foundation(基金) named Hong Kong Emperor Group have together donated 10 million yuan. And he also sent his consolation(安慰) to the people in the disaster areas and encouraged them to hold on because “People all over the country are with you.” Xiao Ke, a songwriter, wrote and recorded a song “I Know You Will Come” to warm the hearts of the people in despair(绝望). CCTV's top show “The Same Song” also held a charity special to help them.
       Both the ticket money and the donated money will be sent to the disaster areas. As the Chinese saying goes (C) “One in trouble, all to help.” I believe that the whole world will become better if everyone of us gives charity to others.
