    During the years of game making, there have been a number of games. Many old games have gone since modern games came out.

Teachers at a primary school asked their students to write articles about games they knew and were surprised by the results. Half of the 50 children in one of the classes wrote about online games. It is easy to see that traditional games like hide-and-seek and jump rope games are unfamiliar(不熟悉的) to many of today's schoolchildren. They like to play computer games, especially in the cities, with the rising popularity of TV, the Internet, video and online games.

    An educationist said, "Traditional games used to be so popular, but over just a few years, kids have forgotten them. It's sad."

    The games that many parents once played were generally outdoor activities which were enjoyed by students during breaks or after school. They usually needed several partners and just a little space.

    Jump rope games, for example, have always been popular in many countries around the world. A kind of jump rope game, played with rubber bands(橡皮筋) which are connected together to make a long rope, is played in many countries.

    Rubber band jumping was once very popular in primary schools. Girls loved playing this game. It can help kids practise their jumping skills and develop coordination(协调性), and also help them meet lots of friends.

    It is common these days to see primary school students spending their breaks in the classroom. They are busy with their studies.

    "When we were young, we played many different outdoor games, but today's children don't know what to play or how to play," a 40-year-old mother said. "They don't know what teamwork is."

Being worried by the situation, educational officers have tried to make some programmes to educate children on traditional games.

    One Tuesday morning, Harry saw all ad(广告) in a window. It said, "Wanted, the Best Salesman in the World. Top Pay." Harry thought he was a great salesman and went to ask for the job. "I am the best salesman in the world," he said to the manager, "Give me the job."

    "You must prove you're the best," the manager said.

    "OK, I will!" Harry answered.

    "Good!" The manager took a box of sweets out of his desk. "Last week I bought a thousand boxes of sweets. If you can sell them all before the end of the week, you can have the job," said the manager.

    "That's easy," Harry said. He took the boxes of sweets and left the office.

    Every day and all day, he went from shop to shop, trying to sell the boxes of sweets. But he couldn't sell one. The sweets were too bad for him to sell. At the end of the week, he went back to the manager. "I'm sorry, Sir." he said. "I was wrong about myself. I'm not the best salesman in the world, but I know who is."

    "Oh," said the manager, "Who?" The person who sold you a thousand boxes of these sweets," Harry said.

    A rabbit is running into its hole. You may ask, "What happened?"

    Well, when a rabbit sees something dangerous, it runs away. Its tail moves up and down as it runs. When other rabbits see this tail moving up and down, they run too. They know that there is a danger. The rabbit has told them something without making a sound. It has given them a signal.

    Many other animals use this kind of language too. When a bee found some food, it goes back to its home. It cannot tell the other bees where the food is by speaking to them, but it does a little dance in the air. This tells the other bees to go with it to find food.

    Some animals say things by making sounds. A dog barks, for example, when a stranger comes near. A cat purrs (发出呼噜呼噜的声音) when it is pleased. Some birds make several different sounds, each with its own meaning.

    But human beings have something that no animals have—a large number of words about things, actions, feelings or ideas. We are able to give each other information and to tell or inform other people what is in our mind or how we feel. By writing words down we can remind ourselves of the things that have happened, or send messages to people far away. No animal can do this. No animal has the wonderful power of language.

    No one knows how man learned to make words. As centuries went by, he made more and more new words. This is what we mean by language.

    People living in different countries made different kinds of words. Today there are about fifteen hundred different languages in the world. A very large English dictionary, for example, contains four or five hundred thousand words. But we do not know all of them. The words we know are called vocabulary. We should try to make our vocabulary larger. Read as many books as possible. When we meet a new word, look it up in the dictionary. A dictionary is the most useful book.
