The following appeared in a memo from a manager of a car dealership.

"Ten years ago, long-term car leasing became available in our country of Mohilia as an alternative to outright car ownership, and leasing has steadily risen in popularity. For each of the last five years, the number of people leasing new cars has surpassed the number buying new cars. The average age of cars driven in Mohilia is six years; hence, if new car leases again outnumber purchases this year, it is likely that the majority of drivers will be driving leased, not individually owned, cars. Therefore, we should change the focus of our business from selling cars to leasing them."


10年前，长期汽车租赁在我们Mohilia国家出现，成为对于汽车完全所有权的一种补充，这种租赁业务的受欢迎度也逐渐增加。过去五年的每一年中，租赁新车的人数都超过了买新车的人数。Mohilia的汽车平均使用时间为6年；因此，如果新车租赁在今年又一次超过购买，有可能大多数驾驶员将会开租来的车而不是私人拥有的车。因此，我们应该把业务重点从出售车辆转向租赁车辆。

Argument137  The following appeared in an editorial in the Mason City newspaper.
"At present, Mason City residents seldom use the nearby Mason River for any kind of recreational activity, even though surveys of the region's residents consistently rank water sports (swimming, fishing, and boating) as a favorite form of recreation. Since there have been complaints about the quality of the water in the river, residents must be avoiding the river because they think that it is not clean enough. But that situation is about to change: the agency responsible for rivers in our region has announced plans to clean up Mason River. Therefore, recreational use of the river is likely to increase, so the Mason City council will need to increase its budget for improvements to the publicly owned lands along the Mason River."

当前，Mason市很少利用附近的Mason河来进行娱乐活动，尽管对该地区居民的几次调查一直指出他们把水上运动（游泳、垂钓和划船）作为他们最喜欢的娱乐形式。由于曾经存在对于这条河水质的投诉，居民一定是因为他们认为河水不够干净才不在这里活动。但这种情况就会改变了：我们地区负责河流管理的部门公布了澄清Mason河的计划。因此，河流的娱乐用途很可能将会增加，因而Mason市的市委有必要增加用于改善Mason河沿岸公共土地的预算。

71. Copper occurs in nature mixed with other minerals and valuable metals in ore, and the proportion of copper in the ore can vary considerably. Until fairly recently, the only way to extract pure copper from ore was by using a process that requires large amounts of electric energy, especially if the proportion of copper in the ore is low. New copper-extracting technologies can use up to 40 percent less electricity than the older method to process the same amount of raw ore, especially when the proportion of copper in the ore is high. Therefore, we can expect the amount of electricity used by the copper-extraction industry to decline significantly.

铜在自然中与其他矿物和有价值的金属混合存在于矿石中，而且矿石中铜的比例可能有很大差别。直到最近，从矿石中提取纯铜的唯一方法是通过一种需要大量电力的流程，特别是当矿石中铜的比例比较低的时候。新的铜提取技术在处理同等数量的原矿石时能够比老的方式节省40％的电力，特别是当矿石中铜的比例比较高的时候。因此，我们可以预期铜矿提取工业所用的电力将会显著减少。

Argument42
The following appeared in a proposal from the economic minister of the country of Paraterra.

"In order to strengthen its lagging economy, last year the government of the nearby country of Bellegea began an advertising campaign to promote ecologically sound tourism (ecotourism). This year the number of foreign visitors arriving at Bellegea's main airport doubled, and per capita income in Bellegea increased by ten percent. To provide more income for the population of Paraterra and also preserve the natural environment of our tiny country, we too should begin to promote ecotourism. To ensure that our advertising campaign is successful, we should hire the current director of Bellegea's National Tourism Office as a consultant for the campaign."

临近城市Bellegea的政府为促进其落后的经济，去年开展了一项对生态旅游的广告推广。今年到达Bellegea主要机场的外国游客数量翻了一番，人均收入增加了10％。为增加Paraterra居民的收入并保护我们有限国土的天然环境，我们也应该推广生态旅游。为保证我们广告策略的成功，我们应该雇佣Bellegea现任国家旅游局的主任来担任广告的顾问。
