答案：Xiao Ming, a lovely Grade 8 student, needs our help! Xiao Ming is suffering from a serious heart disease and has been absent from school since last week. A necessary operation can cure him, but it costs over 250,000 yuan. Xiao Ming's parents are both farmers. They cannot afford such an expensive operation. Without this operation, Xiao Ming's life would be in danger. Let's come together to support Xiao Ming. We are planning to organize a book fair to raise money next Saturday from 10 a. m. to 3 p. m. in the school library. Join us to show Xiao Ming that he is not alone. If all of us give a helping hand, we can save Xiao Ming!
