Do you live in a city? Do you know how cities began? Long long ago, the world had only a few thousand people. These people moved from one place to another. They moved over the land, hunting animals for food. No one knows how or when these people learned about growing food. But when they did, their lives changed. They did not have to move houses any more. They could stay in one place and grow it. People began to live near each other, so the first village grew. Many people came to work in the villages, and these villages became larger and larger. Then people had machines, life in the villages changed again. People built factories. More and more people lived near the factories. So the villages grew into cities. Some of them grew very big. Today, it's strange that some people are moving back to small villages. Can you tell me why ?

    Mum and dad are two of the most important people in your life. You probably see at least one of them every day. And they influence (影响) you more than anyone else you meet in your 1ife. So if your mom loves to read, you just might grow up carrying a book wherever you go, just like she does.

    But parents do a lot more than just passing on their hobbies. Mums and dads care for（关心）their children from the minute they were born. So they are the people we should respect(尊敬) and love best. It's very important to stay close, get along, and build a strong relationship with your parents. But not every child knows how to do this. Here are some ways to help you.

    Spend time together. Don't play a computer game or watch TV, ask your mum and dad to play with you. Go outside together, or read a book out loud.

    Be kind. Little things might mean a lot to your mum or dad. You can make your parents happy with a hug (拥抱), a card, or a joke（笑话）. It's also lovely when a child cleans up his or her room without being asked. And if you try not to fight with your brothers or sisters, your parents might be very happy.

    Do your best at whatever you do. You don't have to be perfect, but when you do your best, you make your parents proud(自豪). It makes them happy to see how you're turning into a great kid. Why? Because it lets them know you're doing a good job.

    Long ago, people did not need money. {#blank#}1{#/blank#}

    As time passed, people learned to raise animals and crops. Sometimes, families produced more than they needed, so they started to trade (交易) with other families. Later, people began to use money as a means of exchange. {#blank#}2{#/blank#}They used shells, rice, salt, large stones, etc.

    During the 600s BC, people began using coins as money. They soon found that coins were easier to carry than goods (货物) and lasted a long time. {#blank#}3{#/blank#}

    The Chinese were the first to use paper money, probably as early as the eleventh century. The Italian traveller Marco Polo saw the Chinese using paper money when he visited China in the 1200s. {#blank#}4{#/blank#}

    Today, we have many ways to pay for things. {#blank#}5{#/blank#}Often, people prefer to pay for things by card. Paying with a card is easier and safer than carrying around a lot of "real" money.
