There are three things you should remember: relax, sleep and eat well. A vacation is a time for relaxing, but very often it is not. Think about what you do when you are a tourist. There are so many places to visit: shop, parks, churches and temples ( 寺庙). You may spend most of the days walking around these places. This can be very tiring. Do not ask your body to do too much. A tired body means a weak body. A weak body gets dick easily. So sit down for a few hours in a nice place. In good weather, look for a quiet park bench.Sleep is also important. If you want to stay healthy, you need to get enough sleep. Your hotel room may be noisy, or the bed may be too hard. Or you may want to stay out late at night. Then you should plan to sleep for an hour during the day. The extra  hour can make a big difference. Finally, if you want to stay healthy, you must eat well. That means eating the right kinds of food. Your boday needs fresh fruit, vegetables, mean, milk and cheese. So, remember this: if you want to enjoy your vacation, take good care of yourself. Give your body some rest. Get enough sleep and eat healthy food. 【小题1】You should ____ while traveling.
