Why do plants grow in some places but not in others? Why does some land have so many plants growing on it, while other land has almost no plants growing on it at all?

    To grow, plants need several things. One is warmth. In very cold places almost nothing grows. Plants also need water. In very dry parts of the Earth only a few unusual plants can grow. That's why there are almost no trees or grass in dry deserts.

    Plants must also have a place to put down their roots and grow. They find it difficult to grow on hard land. The town is built(被建立) on hard land. The plants there have only the soil between the cracks of the stones to grow in.

    Another thing plants must have before they can grow is food. What will happen if we try to make things grow on the sandy beach? A few plants, such as grass, will grow in sand, but most plants won't. Even if the weather is warm enough and we water the plants each day, many of them will die because the sand on this beach has almost no food for plants.

    It is said that more than four million people die each year from smoking. That number is increasing. Seven in ten of those deaths are in developing countries. These numbers are frightening.

    Yet people around the world continue to smoke. The Great American Smokeout has been founded for twenty-five years to show the dangers of smoking and provide support for people who decide to stop smoking. The American Cancer Society says all cigarettes damage the body. It warns that smoking even a small number of cigarettes is dangerous. It is not easy to give up smoking forever. However, doctors say they probably will live longer if they do stop smoking. They will feel better and look better. They also will protect the health of family members who breathe their smoke.

    The American Cancer Society says there is not just one right way to stop smoking. Any useful way to stop smoking is worth trying. They may take long walks or spend time in places where smoking is not allowed. Also, they could eat a small piece of fruit instead of having a cigarette.

    The American Cancer Society says the sooner smokers stop smoking, the more they can reduce their chances of getting cancer and other diseases. It says blood pressure returns to normal twenty minutes after smoking the last cigarette. Carbon monoxide (一氧化碳) gas levels in the blood return to normal after eight hours. After one day, the chance of heart attack decreases. After one year, the risk of heart disease for a non-smoker is half that of a smoker.

Stop smoking before smoking stops you!

Do you know{#blank#}9{#/blank#} (this) two boys? Oh, they are {#blank#}10{#/blank#} (I) cousins, Bob and David. I love my family very much

Have you ever seen the treasures at Sanxingdui?

The number one divine tree (神树) is one of the most famous of them. It includes three parts: a base, the tree itself and a dragon. The base is made to be like a mountain, rising on three sides. {#blank#}1{#/blank#} The dragon is winding (弯曲) its way down to the mountain. The divine tree is divided into three levels. There are three branches on each level. And each branch spreads in two directions. {#blank#}2{#/blank#}

Some people think the Number one divine tree is the tree Fusang in the book "Classic of Mountains and Seas". It describes there live nine birds carrying the sun from east to west in Fusang tree. {#blank#}3{#/blank#} Every day, one bird takes off from the Fusang tree in the east and flies to the Ruomu tree in the west.

It's said that there are in total of ten birds. But on the divine tree there are only nine, so where's the tenth? There are two different ideas. {#blank#}4{#/blank#} However, most people believe the tenth bird isn't there because it is its turn to fly west, carrying the sun.

{#blank#}5{#/blank#} Maybe they wanted to use it to connect heaven and earth. They wanted to reach higher and communicate with the gods. At the same time, they hoped to receive gods'ideas.

Hip-hop dancing（街舞）is popular with many young people today. They like it because they can invent their own moves. They use this dance to show their love for life. It also shows that they feel good about life, that they just want to be themselves and enjoy life, and that they are not afraid of problems. 

Hip-hop dancing has a history of more than 30 years. It first began in the 1980s in the USA. In early times, it was seen in New York and Los Angeles. At that time, many young black people often danced to the music in the streets. They used their legs, arms, heads and even shoulders to dance. Many young people still use most of these moves today. 

Hip-hop dancing became popular all over the world because of the 1983 movie Flashdance. Some people performed Hip-hop dancing in the movie. People enjoyed their performance. They began to dance like them. Then it became popular. There are two kinds of Hip-hop dancing: new school and old school. More and more young people are learning Hip-hop dancing. People believe that it is a good way to exercise their bodies, and that it is good for their health .
