When you go on a trip, it's easier to get sick because your body isn't used to the food, water, and air in a new environment. Here are some tips on keeping your travel experience as healthy as possible.

    Have safe foods and drinks.

    So what foods are safe to eat? Any boiled food, fresh fruit and vegetables are safe for you. Peel(剥) the fruit before eating. You should try to drink only bottled (瓶装的) water when traveling. If you need to use tap water (自来水), you should boil it first.

Take some medicines.

You should also put some medicines in your bags, because they may be hard to find in another country. It's a good idea to always carry your medical history with you. This helps doctors well, and you won't have to worry about forgetting important information.

    Basic Safety

    You'll need to reset your thinking when it comes to traffic safety. The rules of the road aren't the same as they are at home. In some countries, people drive on the left side of the road, and you'll need to be careful before you cross the street. Be sure there are no cars coming when you step into the street: If there are, they may not stop for you!

    More and more children play computer games for a long time. Most parents feel quite worried about that. But in fact, not all games are bad for kids.

    There is a popular game called Mole Manor（摩尔庄园）on line now. In this game, it is a world of the kids. Children can do what they want to do there. They can buy what they want and even the pets. Almost every player has one or two pets called Lam. The players can buy something for Lam and they also want to give them some food to eat. Sometimes kids must wash their pets to keep them clean. At that time, they are the parents themselves. That helps them know how much their parents do for them. There are many other games for kids in Mole Manor. Kids can be a policeman here. They can also be a teacher to help the Lams to learn more.

    Get the kids to play for only half an hour on line. Don't hate all computer games and you can be a good parent.

    Weather has a strong effect(影响) on people. It influences health, influences health(智力), and feelings.

    In August, it is very hot and wet in the southern part of the United States. Southerners have heart trouble and other kinds of health problems during this month. In the northeast and the Middle West, it is very hot at times and very cold at other time. People in these states tend to(趋向) have heart trouble after the weather changes in February or March.

    The weather can also influence intelligence. For example, in a 1983 study by scientists, the IQ scores of a group of college students were very high during a hurricane(飓风), but after the storm their scores dropped 10%. Storm can increase intelligence. Very hot weather, on the other hand, can lower(降低) it. Students in many schools of the United States often do badly on exams in the hot months of the year.

    Weather also has a strong influence on people's feelings. Winter may be a bad time for thin people. They usually feel cold during these months. They might feel sad during cold weather. In hot summer weather, on the other hand, fat people may feel unhappy. At about 18℃, people become stronger.

    Are you feeling sick, sad, tired, forgetful（健忘）, or very intelligent today? The weather may be the reason.

    Many kinds of birds live in the United States, but the number of the birds is becoming smaller every year. One of the leading reasons is the growing number of pet cats. By keeping your pet cats in your home, you can help give birds a better possible chance to live.
