閱讀理解
Since the earliest times , trees have always been very useful and important to man who made use of them in many ways . Even today trees continue to serve man in so many ways .
Trees provide man with fruits and building in the form of wood . Without trees it would be impossible to build houses , boats and even bridges . Furniture(傢俱)such as tables , chairs and beds are made of wood .
In the tropics(熱帶地區)where it is very hot all through the year, trees protect man from the terrible heat . They are also used in preventing good and rich top soil from being washed away during heavy rains which are so common in the tropics .
In there were no trees or vegetation(植被)of some kinds to hold back the soil with their roots soil , heavy rains would wash the rich surface(表面)soil that is so important and necessary to agriculture(農業). The result is that the land becomes a desert .
There are so many desert areas in the world . A long time ago these desert areas must have been very rich fertile(豐產的)areas , but since our ancestors(祖先)in the past hadn’t enough knowledge about science of nature , they cut down all the trees in the areas where they lived and never planted new ones . By and by , the rich surface soil was blown away and washed away by strong winds and heavy rains . In the end the land was turned into useless deserts where nothing could grow .
