I'm going to            tomorrow.   （    ）

    One day Tom tells his friends，" I'm going to have holidays in Beijing. But I can't speak Chinese，so I'm going to have evening classes and have Chinese lessons there for a month." Soon his holidays come and he goes to China happily. After he comes back，his friends ask him，" Do you have any trouble with your Chinese when you are in Beijing，Tom?" "No，I don't." Answers Tom，" But the Chinese do!"
