The Importance of Trees
As we all know, trees are very useful. They are of great benefit to man as follows: First, trees provide us with wood and other products; Second, their roots can allow the rain to sink in and keep the soil, so they help to prevent droughts and floods. Trees can clean air and beautiful life.
Unfortunately, nowadays in many parts of the world lots of people fail to realize the importance of trees. They have cut trees down in large numbers without a plan,which makes the soil washed away. They don't know where there no trees, the rain washed away the surface of the soil and this causes floods.
We ought to plant trees each year and carefully look after new trees in order not to make the forest slowly disappear. Only' in this way can we make the forest serve man forever.
眾所周知，樹有很多的`用處，人類從中得到如下很多益處：第一，樹給我們提供了木材和其他一些產(chǎn)品。第二，它們的根能讓雨水滲進并保持乒壤以免被水沖走，所以樹木可以預(yù)防旱災(zāi)和水災(zāi)。同時樹木還幫我們凈化空氣，美化生活。
不幸的是，今天世界上很多地方人們沒有意識到樹木的重要性。他們無計劃的大量砍伐樹木，這樣使得土壤被破壞，他們不知道那沒有樹的地方，一下雨就把土壤的表層沖走了，導(dǎo)致洪災(zāi)。
我們應(yīng)該多植樹，同時好好照顧小樹，不要讓森林一點點消失，只有這樣才能讓森林永遠(yuǎn)為人類服務(wù)。
