Have you ever planted a few trees on Tree Planting Day? Each year, millions of people, both 1, plant a lot of trees. But this may not be the best way to make your home 2.
Last week we visited a park in Hebei. We were 3 to find most of the trees had been burned. The workers told us that the trees 4 soon after they were planted because they weren't watered well enough. 5 workers burned them and cleaned the place for 6 trees to be planted this year. 7 a card found in one of the dead trees, a student wrote, "I hope this tree will grow up with me to 8 the backbone(栋梁) of our country." The workers said that the survival(存活) of the trees was really more important than 9 trees were planted.
Some people in Beijing now have a new idea that they can donate(捐赠) some money and let professional (专业人士) plant and 10 the trees.
Peter was a small boy. He lived with his parents in a small house near some hills. The people there were all poor.
One night it was very dry and windy. When everybody was asleep, Peter suddenly heard some noise. It came out from the kitchen. He got up and walked to the kitchen. He found that the wood beside the stove(火炉) was on fire. There was no water tap in the house, so he could not put out the fire. He shouted loudly to wake up everyone in the house. Then he ran out of his house and knocked on the doors of many houses to wake the people up. They all ran out of their houses quickly.
At last the fire was put out by the firemen. Many houses were burnt. But nobody was burnt in the fire.
In l620, about half the USA was covered by forests. Today the forests have almost gone. A lot of good land has gone with them, leaving only sand. China doesn't want to copy the USA's example. We're planting more and more trees. We've built the "Great Green Wall" of trees across northern part of our country. The Great Green Wallis 7, 000 kilometres long, and between 400 and 1, 700 kilometres wide. It will stop the wind from blowing the earth away. It will stop the sand from moving towards the rich farmland in the south.
However, more "Great Green Walls" are needed. Trees must be grown all over the world. We wish to have more Green Walls and the world becomes a better place for people to live in.
