Dialogue对话
Martie:Todd, you seem to know a thing or two about math.Can you help me?
Todd:I’ll try.What's the trouble?
M:Oh,it’s these calculus problems that my teacher assigned for homework.I can’t make any sense out of them,can you?
T:I'm an old hand at calculus.Let me see.The function of two plus three equals two times ten divided by four to the sixth power,and…hmm…It's Greek to me, too.
M:I guess the "old hand" is a little out of practice.
T:Well,if neither of us can figure out the answer,then ten to one it's the teacher who made the mistake!
