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 ?

Information Card

    Hey! Mother's Day is coming. Have you planned something good for your mom? If not, try one of these tips.

    What's Her Favorite?

    Buy her something she likes and wrap (包装) it carefully. The best time to give her that is while she is sleeping at night. Put it on the drawer next to her so that when she wakes up she'll be surprised to see it.

    Treat a Queen

    Your house is a palace with a king and queen (it doesn't matter if you're rich or poor). Our mother is the real queen in our life and in our family though (虽然) her duties make her look like she is not. Give the lady a day off and you can do the housework.

    Maybe you could take some of your savings to treat her in the department store. Then, choose nice clothes that would make her look beautiful!

    Have Some of Your Time

    What's your best moment with her? Have you ever had a good time with your mother not talking about your problems? Have you ever told her how much you thank her for the life she gave to you? Maybe you can tell her how happy you were when she was there looking after you during your painful days in your life.

    Tell the magic words

    Those three words can make her heart jump for joy, you know? Just tell her "I love you!" and it would make her smile so sweetly. Just try! We don't want to miss a thing, right?

    Scientists are trying to make the deserts into good land again. They want to bring water to the deserts, so people can live and grow food. They are learning a lot about the deserts. But more and more of the earth is becoming deserts all the time. Scientists may not be able to change the deserts. People are doing bad things to the earth.

    Some places on the earth don't get much rain. But they still don't become deserts. This is because some green plants are growing there. Small green plants and grass are very helpful to dry places. Plants don't let the hot sun make the earth even drier. Plants don't let the wind blow the earth away. When a little bit of rain falls, the plants hold the water. Without the plants, the land can become a desert much more easily.
