Travelling is one of the most important activities and people have been interested in it for many years. Modern traffic develops fast, so travelling to different places has become much faster than before. Staying healthy while travelling can make your trip happier. But do you know how to keep healthy during a trip? The following information may be useful to you.

Before leaving

    ●Wear comfortable shoes, a hat and sunglasses.

     ●Take some necessary medicine with you. They can be used when you get sick or have other problems.

     ●Do some exercise for weeks or months before you leave if you plan to do lots of walking or climbing during your trip.

● Prepare proper food. Before you prepare the food, the first thing you need to think about is how long you will travel with the food. If you take a long trip, you should bring food such as bread, biscuits and some fruit. They don't go bad quickly. The nearer people can bring meat, fish, eggs, milk and even salads and vegetables.

While travelling   

     ●Be sure not to eat dirty food or bad fruit.

     ●Have enough time to take a rest during your trip.

     ●Tap water is not safe, so drink bottled water and always clean the cover of the bottle.

     ●Keep food in good condition. If you take hot food, you should try to keep it hot. For example, you can put it in heavy towels. If you need to keep cold food cold, you can put cold food in a box with ice. When you arrive, put cold food in the fridge. Remember: If you travel with food, keep hot food hot and cold food cold.       

    Now many people like to keep dogs as their pets. But how did dogs become humans' close friends?

    In some places of Europe (欧洲), about 10,000 years ago, some wild (野生的) dogs often came to human's houses to find food. The wild dogs looked different from the ones today. They looked like wolves (狼). At first, they felt ① frightened. They always stood and looked for a short time. Then they got the food and ran away. Sometimes the young dogs couldn't run fast and people caught them. People trained them and the young dogs grew up with the help of people. Slowly, the wild dogs became home dogs. They could make home safe when people were away. They helped people hunt (狩猎). They helped people keep warm on cold nights. ② Sometimes, they could smell and hear danger before people could. In some cold places, they helped people pull (拉) things people need.

    Now there are more than 400 different kinds of dogs in the world. And they look different from each other. The number and kind are growing all the time. Today, some people mainly (主要地) regard dogs as pets. In fact, dogs are really our close friends. We should protect them from being killed.

    An English gent leman always takes an umbrella and wears a hat. Why? In England, it rains often. The rain comes at any time, so an umbrella is necessary (必要的) in people's life. English gentlemen love to take a long black umbrella. It is useful when the rain comes. And it is also a style. The hat plays an important part in their life too. If two men meet in the street,  they take off (脱掉)  their hats to show their respect (尊重) to each other. If a man visits his friend, he takes off his hat frst when he gets into the room. If he goes to a party, he can only put the hat on his chair, but not on the table. You don't have the two things, but you can still (仍然) be a gentleman. Always be nice to others and be ready to help others. Show your respect and love to old people, women and children. Never shout. Never lose your temper (发脾气).

    Some people succeed, while others may not. This is because some people have certain qualities, which others do not.

    The first thing you must remember is that in order to succeed, you must be optimistic (乐观的). If you do not expect to win, you will not try as hard as those who do expect to win. You also need to have a clear aim and a reason for doing something because motivation (动力) is a key to achieving success.

    Another quality that helps people succeed is creativity-thinking about things in a different way and wondering how others would do the same thing. Think about some successful people you know.

    Reading is another quality to success, as it will help you learn about how other people have achieved success. If you want to learn how to set up a successful business, you should read books about people like Bill Gates and Jerry Yang, who have achieved amazing success in their areas of business. Practicing is also important if you want to succeed because practice makes perfect.

    If you feel confident about what you do, this confidence will make other people believe in you as well.

    James Watt was an English boy. He liked asking questions and was always thinking hard.

    One day he was sitting in the kitchen with his grandmother. There he saw a kettle (壶) on the fire. Some steam began to come out of the kettle. The lid (盖子) was shaking. "Grandma, what's in the kettle?" he asked. "Water, my child… nothing, but water." "But I know there is something else. It pushes the lid up. How did the steam get under the lid?" "It comes from the hot water."

    The boy said to himself, "The steam must be very strong. It can push things. If there is more water, the steam will be much stronger."

    Many years later James Watt tried to make steam work for people. He gave the world the first engine.
