阅读理解：阅读下列短文，回答文后问题，选择最佳答案Trees mainly serve man in three important ways: They provide him with wood and other products; they provide him shade; and they help to prevent droughts and floods.Unfortunately, in many parts of the world, man has not realized that the third of these services is the most important．In his eagerness to make money from trees, he has cut them down in large numbers, only to find that without them he has lost the best friends he had. And besides, 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 more serious: for where there are trees, their roots break up soil allowing the rain to sink in and also bind(固定) the soil, thus preventing 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 the top-soil is gone, nothing remains but worthless desert.Two thousand years ago，a rich and powerful country cut down its trees to build warships, with which to gain itself an empire．It set up the empire, but, without its trees, its soil became poor and grew weak. When the empire fell to pieces, the home country found itself faced by floods and starvation(饥荒)．1. According to the passage, which is the most important service of trees to man? A、 A. They help him make money. B、 B. They give him cool. C、 C. They give him wood and other things. D、 D. They help him to stop droughts and floods.大学英语1 受弯构件的挠度变形按（ ）原则来计算 混凝土结构设计原理 On the one hand, I want to sell the house, but on other hand I can’t bear the thought of moving. 大学英语（上） 符合哪种情况的保险合同，是无效合同 （ ） 保险学 关于佩戴首饰说法，错误的是（）。 社交礼仪 病例对照研究中，使用新发病例的优点是 预防医学基础
