Travelling is a very good activity. When you get tired of your work or study, and when you have free time, you can go to a beautiful place to enjoy the beauty of nature or other cities. You can breathe fresh air, meet different people and make friends with them. It’s good for your health to do so.
But sometimes, travelling is not an enjoyable thing. For example, the weather can be changeable. There may be rain when you travel. You may catch a cold or be ill while travelling. The worst thing is that the thieves may steal(偷) your money. All these may happen to a tourist.
When you go on a trip, you must get everything ready. Firstly, you must have clear information about the weather. Secondly, ask a friend to go with you so that you can help each other. Thirdly, you must be careful everywhere and try not to cause accidents. If you do this, you will surely enjoy your travel.

Jack is an Englishman. He likes travelling around the world. He has visited many countries. He knows few foreign languages, but he can always find someone who knows enough English to understand what he says. Last summer he went to China. He enjoyed himself in China and liked Chinese food very much.
One day he went into a restaurant in a small village. He knew the Chinese word ‘rice’, so he ordered some rice.
