解析： 19-22
M: Hi, Betty, nice to see you again. How long ago did we two meet in this Student Centre I’m glad the final examinations are over, and we don’t have to stay up all night to cram all the academic stuff into our minds.
W: Yes. I’m glad that we can be here again to relax and have fun with other fellow students. And now we can look forward to our summer holiday. I’ve been thinking of going to the States for some time.
M: I think it would be much better for you to go on holiday here in England than to the United States. To start with, it’s a lot nearer and so it will be much cheaper to get around. That means you will have far more money to spend.
W: That may be true, but think about when you get there. There is much more to do in the United States, there are so many different things to see and places to go. Imagine, you could go to New York, San Francisco, the Grand Canyon, and Disneyworld...
M: Exactly, Disneyworld! I have been dreaming of going there ever since my childhood.
W: So you’re changing your mind, aren’t you!
M: I’m still worrying about the cost of taking a trip to the States. Meanwhile, if you stay here in England, you can probably take up some part-time jobs. That way, you can earn extra money to support your study next semester.
W: Maybe you are right. I will think it over and talk about it with my parents while I’m home. Anyway, it is they who pay for my study here in the University.
