Mr. Li： You've traveled abroad a lot， Tom， so would you like to tell me something about clearing customs.

Tom： 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.

Mr. Li： Then what are the differences between the green channel and red channel？

Tom： 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.

Mr. Li： I see.

Mr. Li： I'm told that we'll have to state the purpose of going to a certain country， is it true？

Tom： That's right. People go aboard for different purposes： some for pleasure， some on vacation， some on business， and some for other purposes.

Mr. Li： I'm going to New Zealand for sightseeing. What should I say if they ask about my purpose？

Tom： Just saying "sightseeing" is OK.

李先生：湯姆，你經(jīng)常出國旅游，能向我介紹一下關(guān)于通關(guān)的情況嗎？

湯姆：到達一個國家時要通關(guān)。許多國家的海關(guān)有兩種通道：綠色通道和紅色通道。還有些國家如印度有三種通道：白色通道、綠色通道和紅色通道。

李先生：那么綠色通道和紅色通道之間有什么區(qū)別呢？

湯姆：如果你攜帶的東西超出免稅的范圍或?qū)儆诮麕锲罚憔偷脧募t色通道通過并向海關(guān)官員申報物品。如果你沒有需要申報的物品而海關(guān)官員又沒有阻攔你，你就可以直接通過綠色通道了。

李先生：我明白了。

李先生：我聽說去一個國家時需要陳述旅行的目的，是嗎？

湯姆：是的。人們出國都各有目的：有的為了消遣，有的出去度假，有的是因公出差，有的是為了其他目的。

李先生：我要去新西蘭觀光，如果他們問我旅行的目的我該怎么說呢？

湯姆：說“觀光”就行了。
