A：You've traveled abroad a lot, Jim, so would you like to tell me something about clearing customs.
      吉姆，你经常出国旅游，能向我介绍一下关于通关的情况吗？

B：When you arrive in a country, you clear customs. A lot of countries have two channels: the green channel and the red channel. Some countries, like India, have three channels: the white channel, the green channel and the red channel.
      到达一个国家时要通关。许多国家的海关有两种通道：绿色通道和红色通道。还有些国家如印度有三种通道：白色通道、绿色通道和红色通道。

A：Then what are the differences between the green channel and red channel?
      那么绿色通道和红色通道之间有什么区别呢？

B：If you have more than the duty-free allowances or prohibited goods, you go through the red channel and declare them to a customs officer. If you otherwise have nothing to declare, you go straight through the green channel unless you are asked to stop by an officer. 如果你携带的东西超出免税的范围或属于禁带物品，你
      就得从红色通道通过并向海关官员申报物品。如果你没有需要申报的物品而海关官员又没有阻拦你，你就可以直接通过绿色通道了。

A：I see.I'm told that we'll have to state the purpose of going to a certain country, is it true?
      我明白了。我听说去一个国家时需要陈述旅行的目的，是吗？

B：That's right. People go aboard for different purposes: some for pleasure, some on vacation, some on business, and some for other purposes.
      是的。人们出国都各有目的：有的为了消遣，有的出去度假，有的是因公出差，有的是为了其他目的。

A：I'm going to New Zealand for sightseeing. What should I say if they ask about my purpose?
      我要去新西兰观光，如果他们问我旅行的目的我该怎么说呢？

B：Just saying "sightseeing" is OK.
      说"观光"就行了。
