9、the following four texts. Answer the questions below each text by choosing A, B, C or D._The word conservation has a thrifty(节俭) meaning.

11、ystem 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 cou
12、ld be bought in any quantity from distant woodlands; soil destruction and river floods were not national problems and 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 our
13、selves 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 in the ground is just as important to us as a knowledge of the basic arithmetic formulas.
14、We need to know why all watersheds need the protection of plant life and why the running current 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 kn
15、ow 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.(分数:

To help solve their traffic woes, some rapidly growing U.S. cities have simply built more roads
21、. But traffic experts say building more roads is a quirk-fix solution that will not alleviate the traffic problem in the long run.
