北师大版七下英语 Unit 5 Lesson 14 My First Day 巩固提升 一、阅读理解-阅读选择（共1小题） Since the earliest times, trees have always been very useful and important to man. Even today trees serve man in many ways. Trees provide man with fruits and building materials in the form of wood. Without trees it may be impossible to build houses, boats or bridges. Furniture such as tables, chairs and beds is made of wood too. In the tropics (热带地区), trees protect man from the terrible heat. They are also useful in preventing good and rich topsoil from being washed away during the heavy rain. If there were no trees or vegetation (植被) to hold the soil with their roots, heavy rains would wash away the rich surface soil that is so important to agriculture. 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 were fertile (肥沃的) areas, but since our ancestors (祖先) in the distant past had no enough knowledge about the science of nature, they cut down all the trees in the areas and never planted new ones. By and by, the rich surface soil was blown away and washed away by strong wind and heavy rain. In the end the land was turned into useless deserts where nothing could grow. 1.
