Traveling is a very good activity. When you are fed up with your work and when you can get a holiday，you can go to the beautiful spots to enjoy the beauty of nature and the special character of other cities. You can breathe fresh air，visit some places of interest，meet different people and make friends with them. If you do so，you will forget your tiredness and troubles and build up your health. As a result，you will feel fully relaxed and you will have the energy to finish the new tasks waiting for you.

But sometimes，traveling is not an enjoyable thing. For example，when the bus or car you take has a bad accident，you just sit in and waste your time. What’s more，the weather can be changeable. If you are climbing a mountain，it may rain suddenly. You may be caught in the rain and may catch a cold. The worst thing is that you may have your money stolen and you may have an injury. All these are terrible things that can happen to a tourist.

Therefore，when you are going on a trip，you must prepare yourself carefully. Firstly，you must have clear information about the weather. Secondly，you should choose a good companion so that you can help each other. Thirdly，you must be careful everywhere and try to avoid accidents. If you do this，you’ll surely enjoy your travels and avoid any unnecessary trouble.
