看了半天,没有问这两道题的?可是我还是不太清楚啊,题干的层次内容和问题选项都感觉模模糊糊的。题干中是两个相矛盾的结论吗? 拜托nn们帮忙翻译一下题干和正确选项好吗?不胜感激啊~~ Hardin argued that grazing land held in common (that is, open to any user) would always be used less carefully than private grazing land. Each rancher would be tempted to overuse common land because the benefits would accrue to the individual, while the costs of reduced land quality that results from overuse would be spread among all users. But a study comparing 217 million acres of common grazing land with 433 million acres of private grazing land showed that the common land was in better condition. 85.The answer to which of the following questions would be most useful in evaluating the significance, in relation to Hardin’s claim, of the study described above? (C) Was the private land that was studied of comparable quality to the common land before either was used for grazing? 86.Which of the following, if true and known by the ranchers, would best help explain the results of the study? (D) If one user of common land overuses it even slightly, the other users are likely to do so even more, with the consequence that the costs to each user outweigh the benefits. 谢谢各位nn们了啊~~我是新手,请多关照啊~~ |
