2--How nice! Are you going to convert some RMB to US dollars?
 
1--Yes. But I will not take much cash with me I can ask the bank to give me the traveler's checks. So it will be safer.
 
2--How can you cash them when you arrive in the United States?
 
1--I will go to the bank, give them my check, show them one piece of my identifications, and the most important thing is that I should sign my name to endorse the check.
 
2--It sounds quite simple. Next time when I travel abroad, I will apply for this kind of check too.

译文：

1--我要到美国去参加我女儿的毕业典礼。
2--真好！那你准备兑换一些美元吗？
1--是啊。但我不会随身带很多现金。我可以请银行给我旅行支票，这样会更安全一些。
2--你到了美国后怎么把它们兑成现金呢？
1--我会到银行去，把支票交给他们，然后出示我的证件，最重要的一点就是我应在支票上签名。
2--听起来还挺简单的。下次我到国外去旅游，也要申请这种支票。
