Mary: What are you going to do this weekend, Lucy?
Lucy: much. How about you, Mary?
Mary: I'm going to buy my father a present for his fortieth birthday. Would you like to go with me?
Lucy: I'd love to, but where would you like to go shopping?
Mary: place where they have many different stores.
Lucy: I hear a new shopping center just opened downtown.
Mary: That great. What time would be good for you?
Lucy: How 2:30?
Mary: Sure. That would be fine.
Lucy: Where should we meet, then?
Mary : meet just outside the shopping mall.
Lucy: OK. See you then.
Mary: See you.
（1）句意：没什么事。根据Mary: I'm going to buy my father a present for his fortieth birthday. Would you like to go with me? 可知玛丽要求露西去购物，因此露西这个周末将没有什么事做，故此处为Nothing。
（4）句意：2点30分怎么样？How about sth? 某事怎么样？故此处为about。
（5）句意：让我们就在购物中心外面见面吧。Let sb do sth让某人做某事，此处表示建议，故用Let's。
