A concert was given to several famous singers last Saturday. Tickets were very hardly to get. Since I wanted to attend that concert, I bought one at the high price. For the first half an hour, the concert went on smooth. The nice shows of the singers were warmly welcomed by the audience, many of them couldn’t help burst into tears. Before long the microphone went wrong. Some people begin to make noise. The members of the theatre tried to keep in order, but failed. He had difficulty in continuing the concert. Thus, a perfectly good concert caused to be of no value by some uneducated people.
