阅读理解 The word “conservation” has a thrifty meaning. To conserve is to save and protect, to leave what we ourselves enjoy in such a 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 could “last forever”. Most of the citizens of earlier generations knew little or nothing about the 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 school work; scientific forestry was a new idea; wood was still cheap because it could be brought in any quantity from distant woodlands; soil destruction and river floods were not national problems; nobody had yet studied long-term climatic cycles in relation to proper land use; 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 correcting the mistakes of our forefathers. Conservation should be made part of everybody’s daily life. To know about the water table (水位) in ground is just as important to us as a knowledge of the basic math formulas(公式). We need to know why all watersheds (上游集水区) need the protection of plant life and why the running current of streams and rivers must be made to give 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, grown 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（立方体的） volume above the earth. In a word, it should be our goal to restore as much of the original beauty of nature as we can1.The author’s attitude towards the use of natural resources is_________A.positiveB.uninterestedC.optimisticD.critical2.According to the author, the greatest mistake of our forefathers was that________A.they had no idea about scientific forestryB.they had little or no sense of environmental protectionC.they were not aware of the importance of nature studyD.they had no idea of how to make good use of raw materials3.To avoid repeating the mistakes of our forefathers, the author suggests that ________A.we plant more treesB.natural sciences be taught to everybodyC.environmental education be given to everybodyD.we return to nature4.How can you understand the underlined sentence in the last paragraph?A.Our living space on the earth is getting smaller and smallerB.Our living space should be measured in cubic volumeC.We need to take some measures to protect spaceD.We must preserve good living condition for both birds and animals

DBCD解析1.作者态度题。结合第一段“foolish idea”及最后一段可明显感觉到“作者对自然资源的开发持批评态度”。选D。2.细节理解题。从第一段后半部可知“祖先基本没有环保意识”。选B3.细节理解题。最后一段第二句“环保应该人人有份，成为大家生活的一部分”，显然和C项意思吻合。4.句意理解题。从最后一段结尾处可推知“我们要努力为人类以及人类的朋友维护良好的生存环境”。 选D。
