People visit other countries for many purposes. Some travel on businesses; others travel to visit interesting places that are only found in other countries.
Wherever you go, and for whatever purpose, it’s important to be safe. A tourist can attract a lot of attention from local people. While most people you meet when travelling are sure to be nice, there are dangers—theft being the most common. So prepare for your trip in advance.
As you prepare for your trip, make sure you have the right paperwork. You don’t want to get to your destination （目的地）only to find you have the wrong visa, or worse, that your passport is about to expire (到期). Also, make sure you travel with proper medical insurance, so that if you are sick or injured during your travels, you can be treated. If you want to drive while you are abroad, make sure you have an international driver’s license.
If you need to take medicine with you—such as travel-sickness pills—keep it in its original container（容器）. If you don’t, you may find yourself doing a lot of explaining to customs officials at your destination.
Buy a guidebook and read about the local customs of the country you are going to. Also, try and learn a few basic words and phrases—don’t assume that the local people will speak your language.
When you get to your destination, you’d better use official transport. Always go to the bus and taxi stands, don’t accept rides from strangers who offer you a lift. If there is no meter in the taxi, agree on a price before you get in. If you prefer to stay in cheap hotels while travelling, make sure you can lock the door of your room from the inside. If you are travelling with valuables such as jewelry, or a lot of money, you should ask about a safe for storing them in. Finally, remember to smile. It’s the friendliest and most sincere form of communication, and is sure to be understood in any part of the world!
