1.The following is a memorandum issued by the publisher of a newsmagazine, Newsbeat, in the country of Dinn.
"Our poorest-selling magazine issues over the past three years were those that featured international news stories on their front covers. Over the same period, competing news-magazines have significantly decreased the number of cover stories that they devote to international news. Moreover, the cost of maintaining our foreign bureaus to report on international news is increasing. Therefore, we should decrease our emphasis on international news and refrain from displaying such stories on our magazine covers."
2.The following recommendation was made by the president and administrative staff of Grove College, a private institution, to the college s governing committee. 来源：考试大
"We recommend that Grove College preserve its century-old tradition of all-female education rather than admit men into its programs. It is true that a majority of faculty members voted in favor of coeducation, arguing that it would encourage more students to apply to Grove. But eighty percent of the students responding to a survey conducted by the student government wanted the school to remain all female, and over half of the alumni who answered a separate survey also opposed coeducation. Keeping the college all-female, therefore, will improve morale among students and convince alumni to keep supporting the college financially."
3.The following appeared in a letter to the school board in the town of Centerville.
"All students should be required to take the driver s education course at Centerville High School. In the past two years several accidents in and around Centerville have involved teenage drivers. Since a number of parents in Centerville have complained that they are too busy to teach their teenagers to drive, some other instruction is necessary to ensure that these teenagers are safe drivers. Although there are two driving schools in Centerville, parents on a tight budget cannot afford to pay for driving instruction. Therefore an effective and mandatory program sponsored by the high school is the only solution to this serious problem." 来源：考试大
4.The following is a memorandum from the sales director to the president of the Healthy-and-Good food company. 来源：考试大
"A recent study indicates that Venadial, a new margarine currently produced only in the country of Alta, actually reduces cholesterol levels. Derived from the resin of pine trees, Venadial works by activating a metabolic response that is not yet well understood. However, cholesterol levels fell ten to fifteen percent among participants in the study who consumed Venadial daily, and the risk of heart attack by one-third. In addition, the new margarine is so popular that stores in Alta are unable to keep it on their shelves. Therefore, if our company obtains the exclusive right to sell Venadial internationally, our profits are sure to increase substantially within a very short time."
