Have you ever planted trees before?   Every year, millions of people, both    1    ,   plant many trees. But this may not be the best way to make your home a    2    place.

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 of the trees was really more    9    than the number of the trees that were planted.

Some people in Beijing now have a  new idea that they can donate(贡献) some  money and let professionals (专业人员)  plant and   10   the trees.

Trees are useful to man in three important ways: they give him wood and other useful things, they give him cool places, and they help to stop drought and flood.

Unluckily, in many parts of the world, man has not found that the third of these points is the most important. Man wants to make money from trees, so he has cut them down in large numbers, only to find that without them he has lost the best friends he had. And also, he is usually too careless to plant and look after new trees. So the forests slowly disappear.

This does not only mean that man will have fewer trees. The results are even worse: for where there are trees, their roots break up soil-make the rain in-and also bind the soil, thus stopping it from being washed away easily; but where there are no trees, the rain falls on hard ground and flows away, causing floods and carrying away the rich top-soil. When all the top-soil is gone, nothing is left but useless desert.
