Question 85-86 are based on the following.
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.
86. Which of the following, if true and known by the ranchers, would best help explain the results of the study?
(A) With private grazing land, both the costs and the benefits of overuse fall to the individual user.
(B) The cost in reduced land quality that is attributable to any individual user is less easily measured with
common land than it is with private land.
(C) An individual who overuses common grazing land might be able to achieve higher returns than other
users can, with the result that he or she would obtain a competitive advantage.
(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.
(E)There are more acres of grazing land held privately than there are held in common.
选项D是什么意思？？
OG 解说得满清楚啊。就是说如果每个人都多用的话，摊到每个人头上的费用也就会增加，所以大家都很小心地用，不overuses, 所以common grazing land 的状态比private grazing land 的状态要好。对吗？
共同探讨，一起进步。
谢谢MM的回复，我明白了
原来我的脑子进水了
把overuses it even slightly，理解为过度使用得轻微一些了
唉 一起进水 我也这样认为了 看来我的阅读能力还是很差啊！怎么办。。。
谢谢，我也是这题不懂。看了之后似乎有些明白，但是感觉自己对解释题的思路和方法把握不准，NN们能不能稍微指点一下，谢谢先。
(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.
是不是可以这么翻：如果一个user即使是轻微得过度使用公共地，其他user也有可能这么做甚至更厉害，这样导致对每个user的费用超过其收益。
由此可以看出user会因为顾及个人利益而不过度使用公共地，由此公共地情况比私人地好
好像也蛮勉强解释了那个现象。
请指教

我觉得你的中文是翻译的没有问题的
但是我不觉得是勉强解释,呵呵,首先看题目找出矛盾多在.
题目中说:
大家用公共草地不仔细=>公共草地比私家草地差.这里隐含了一个必要的因素就是大家是以自己利益为先的.
但是调查显示公共草地比私家草地要好,
选项D正好解释了为什么大家在以自己利益为先的情况下还是得出了公共草地比私家草地要好,不是因为大家大公无私,而是因为用了公家的更影响自己的利益.
D正好用题目中的两个矛盾的共同点来解释.
不知道有没有说明白,欢迎再讨论
我看了半天， 这个E 为何不对，
(E)There are more acres of grazing land held privately than there are held in common.
说明在 私田放牧 的机率高，
不正是解释了 common land 保持状态好吗？
再问一次。
help!!!!!!!!!!
没有人理我!
up !
这是第二次复习，这个问题仍然不懂
没有人理我，看来GG没有MM受欢迎。

e 是无关选项， 私田放牧纪律变大也是你的猜测，也可能变小呢。 都留自己的地闲着， 就只用公家的。
看了几遍还是想不明白，可能这个情景对于中国背景的考生是不好理解的。
你多用，我也多用，看谁用得又快又多，占的便宜就比别人多嘛，反正是大家掏钱一起养。所以公共牧场不可能好。
