The word conservation has a thrifty(节俭) meaning. To conserve is to save and protect, to leave what we ourselves enjoy in such good condition that others may also share the enjoyment. Our forefathers had no idea that human population would increase faster than the supplies of raw materials; most of them, even until very recently, had the foolish idea that the treasures were "limitless" and "inexhaustible". Most of the citizens of earlier generations knew little or nothing about complicated and delicate system that runs all through nature, and which means that, as in a living body, an unhealthy condition of one part will sooner or later be harmful to all the others.
Fifty years ago nature study was not part of the school work; scientific forestry was a new idea; timber was still cheap because it could be brought in any quantity from distant woodlands; soil destruction and river floods were not national problems; people had hardly studied long-term climatic cycles in relation to proper land uses even the word "conservation" had nothing of the meaning that it has for us today.
For the sake of ourselves and those who will come after us, we must now set about repairing the mistakes of our forefathers. Conservation should therefore, be made a part of everyone’s daily life. To know about the water table (水位) in the ground is just as important to us as a knowledge of the basic arithmetic formulas. We need to know why all watersheds (分水岭) need the protection of plant life and why the running currents of streams and rivers must be made to yield their full benefit to the soil before they finally escape to the sea. We need to be taught the duty of planting trees as well as of cutting them. We need to know the importance of big, mature trees, because living space for most of man’s fellow creatures on this planet is figured not only in square measure of surface but also in cubic volume above the earth. In brief, it should be our goal to restore as much of the original beauty of nature as we can. [br] It can be inferred from the passage that earlier generations didn’t realize______.
选项
A、the interdependence of water, soil, and living things
B、the importance of the proper land use
C、the harmfulness of soil destruction and river floods
D、the extraordinary rapid growth of population
答案
A
解析
文章第三段首先说“我们应着手弥补先辈们的错误,要把环境保护作为我们日常生活的一部分”,接着又谈到“认识地下水位的重要性”,再谈到“森林、水、人类之间的相互关系”。由此可推断“先辈们没有认识到土壤、水、生物的相互依存关系”,故选A)。
