问题     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] What does the author imply by saying "living space" is "figured", also in "cubic volume above the earth" (Para. 3)?
选项 A、Our living space on the earth is getting smaller and smaller.
B、Our living space should be measured in cubic volume.
C、We need to take some measures to protect space.
D、We must create better living conditions for both birds and animals.
答案 D
解析 本文主题是“环境保护”。根据最后一段“我们需要了解高大树木的重要性，因为对于与人类共同生活在这个星球上的大多数生物来说，生存空间不仅以平方面积来理解，还以立方空间来理解。”本句首先提到需要高大的树木，后说明原因。由此可推出，既要保护生活在地球陆地上的动物生活环境。也要保护生活在树木上的鸟类的生存环境。故选D)．
