83、The following appeared in the editorial section of a newspaper in the country of West Cambria.
The practice of officially changing speedlimits on the highways whether by increasing or decreasing them is a dangerous one. Consider what happened over the past decade whenever neighboring East Cambria changed its speed limits: an average of 3 percent more automobile accidents occurred during the week following the change than had occurred during the week preceding it even when the speed limit was lowered. This statistic shows that the change in speed limit adversely affected the alertness of drivers.
86、The following appeared as part of an article in the business section of a daily newspaper.
Company A has a large share of the international market in video-game hardware and software. Company B, the pioneer in these products, was once a $12 billion-a-year giant but collapsed when children became bored with its line of products. Thus Company A can also be expected to fail, especially given the fact that its games are now in so many American homes that the demand for them is nearly exhausted.
105、The following appeared in an editorial from a newspaper serving the town of Saluda.
The Saluda Consolidated High School offers over 200 different courses from which its students can choose. A much smaller private school down the street offers a basic curriculum of only 80 different courses, but it consistently sends a higher proportion of its graduating seniors on to college than Consolidated does. By eliminating at least half of the courses offered there and focusing on a basic curriculum, we could improve student performance at Consolidated and also save many tax dollars.
108、The following appeared as part of a business plan created by the management of the Take Heart Fitness Center.
After opening the new swimming pool early last summer, Take Heart saw a 12 percent increase in the use of the center by members. Therefore, in order to increase the number of our members and thus our revenues, which depend on membership fees, we should continue to add new recreational facilities in subsequent years: for example, a multipurpose game room, a tennis court, and a miniature golf course. Being the only center in the area offering this range of activities would give us a competitive advantage in the health and recreation market.
110、The following appeared as part of a memorandum from the loan department of the Frostbite National Bank.
We should not approve the business loan application of the local group that wants to open a franchise outlet for the Kool Kone chain of ice cream parlors. Frostbite is known for its cold winters, and cold weather can mean slow ice cream sales. For example, even though Frostbite is a town of 10,000 people, it has only one ice cream spot the Frigid Cow. Despite the lack of competition, the Frigid Cows net revenues fell by 10 percent last winter.
83、West Cambria国的报纸社论：
正式改变高速路限速的行为，不论是提速还是降速，都是非常危险的。看看邻国West Cambria10年来每次改变限速时发生的事情：改变限速后的一周内的交通事故比之前的一周内多出3%，那怕限速被降低也是一样的。这个统计说明改变限速干扰了司机的警戒性。
86、日报的商业版：
公司a在视频游戏的硬件软件方面有很大的国际市场份额。公司b是这些产品的先锋，而且曾经一度是年收入120亿元的巨人，但在孩子们厌倦了它的系列产品后崩溃了。因此公司a也将失败，考虑到它的产品已经占据了那么多的美国家庭，对他的需求已经接近枯竭。
105、Saluda镇的报纸的编者按：
Saluda统一高中提过超过200中不同的课程供它的学生选择。路那头一所小的多的私立学校提供80种基本的课程，但是它的毕业生升入大学的比例始终比统一高中要高。去除至少一半的课程而着眼于基本课程，我们可以改善统一高中学生的表现并省下税收收入。
108、Take Heart健身中心的管理者起草的商业计划：
去年夏天开了新的游泳池以后，TH发现会员对中心的使用率增加了12%。因此，为了增加我们的会员数量和决定于会员费的收入，我们应该在以后几年中继续增加新的娱乐设施：比如，一个多功能游戏室，一个网球场，一个迷你高尔夫球场。作为本地唯一一家提供各种活动的健身中心，我们将在健身和娱乐市场建立竞争优势。
110、Frostbite国家银行的借贷部门的备忘录：用的住宅单元，从而增加使用率。同样的，为了不让学生选择住在校外，住宅办公室应该降低租金来扩大需求。
