Up in the Sky

    Take a trip up a hill on a windy day. What is flying high in the sky? It isn't a bird or a plane. It is a kite!

    Kids and adults like flying kites. Long ago, the first kites were made by Chinese people. Then, people around the world began flying kites.

    One story tells a man's hat got lifted off by wind. He had fun chasing his hat, so he did it again! His hat became the first kite. Other stories tell that people liked watching leaves on windy days. They tied leaves to strings and watched them fly.

    Long ago, kites became important in keeping China protected. A man might be lifted up by a kite while he spied(监视) on an enemy. He could use the kite to fly high like a plane. He could also fight from the air!

    Kites come in many shapes, sizes, and styles. They are usually made of cloth or paper. A kite might be shaped like a bird, a fish,  or just a box. Kites are also painted with colors.

    You can use a kite to catch fish. First you tie a fishing line to a kite. Then you put bait(鱼饵) on the line. You watch the kite with hopes as it flies over the water. When you pull the kite down, you might find a fish on your line! Some people think this is more fun than using a fishing pole(杆).

    Many countries have special days to honor kites. People make, sell and fly many types of kites. There are several kite festivals in China. The Beijing International Kite Festival is usually held in April every year. People spend all days flying kites. You might see famous fighter kites. People fly these kites quite fast and try to cut other flyer's lines.

    There is much to learn about kites. From long ago in China until now, kites have had many uses. They have been used for spying, fighting, and fishing. But the best way to use a kite is to fly it high for fun!

    April 22 is Earth Day. Everyone on earth should care about and protect the earth! The earth has warmed by about 1 °F over the past 100 years, but why and how? Well, scientists are not quite sure. Maybe the earth gets warmer and warmer on its own. {#blank#}1{#/blank#}

    First, greenhouse effect(效应) is a very important reason for the change of the earth. People give out too much energy into the air every year. It makes the earth warmer. {#blank#}2{#/blank#} Sometimes it becomes too hot and sometimes too cold. Sometimes there is too much rain and sometimes too little. The change of the climate makes the earth warmer. In turn, the warmth of the earth changes the climate, too.

    When the earth becomes warmer, there may be more rain and a rise in sea level. {#blank#}3{#/blank#} On a Pacific island, 100 people have to move to higher ground because the sea is rising. These people can no longer live on the coast. Before that, two islands without people went underwater in 1999. Scientists say that the seas can rise by nearly one metre by 2100.

People can affect the earth's air, land and water. As for us, we can do many things to protect the earth.{#blank#}4{#/blank#} We can tell more people about protecting the earth.

    Eaten any wood today? You may have! And you possibly brushed your teeth with it and you are even dressed with wood. You might know that paper is made from wood. But we get a lot more from trees than paper! In fact, more than 5,000 wood products make our lives better each day. It's true! From toothpaste to photo film, wood products are all around us.

    Wood resin(树脂) is one of many chemicals we get from trees. When a tree gets hurt, resin will form as a protective(保护性的) coating around the wound to stop the insect. People collect the resin and use it to produce paint, glue and soap.

    There are also tree-based chemicals in many of the foods we eat and drink. Some of these chemicals are used to add colours to soft drinks, others to keep food from going bad too quickly. For example, snack food, milk shake and ice creams can be made with cellulose (纤维素) from trees.

    Our life is full of products that come from trees. Now, how many tree products can you see from where you are sitting right now?

    It's the end of class. When the bell rings, students of a Foreign Languages School in Shenzhen quickly take out their mobile phones. They like to log on (登录) to their micro blogs to check the funny things that have happened in the last hour.

    Micro blogging has swept the country during the last few years. Recent surveys show that most students in middle schools have a micro blog, and some even update their blogs more than five times a day.

    "We learn many fresh and interesting things on micro blogs and they have become popular topics in class," said Liang Jianmin, 14, a student from Harbin No. 3 Middle School. "If you do not know about them, you are out.”

    It is also a great place for students to relax." My parents always ask me to study hard, and encourage me before exams, but actually it adds pressure," said Zhang Yazhe, 15, a student from a Foreign Languages School. "When I share these feelings on my micro blog, I get many replies from friends in the same situation, which makes me feel better."

    But parents are worried that micro blogging could be a waste of time. Some misleading messages may even be dangerous to kids.

    Shen Mingde, a professor, suggests parents not worry too much that kids are crazy about micro blogging. Instead， however, it can also become a window for parents to understand their children. "If parents can read their children's micro blogs, they'll know their thoughts, it can lead to better communication and solutions to problems," he said.

    He also gives some advice to kids.

    Don't micro blog for more than one hour a day.

    Never micro blog in class.

    Try to talk face to face with people from time to time.

    Be critical(批判性的). Not all the messages on the micro blog are true.
