"Although the sales of Whirlwind video games have declined over the past two years, a recent survey of video-game players suggests that this sales trend is about to be reversed. The survey asked video-game players what features they thought were most important in a video game. According to the survey, players prefer games that provide lifelike graphics, which require the most up-to-date computers. Whirlwind has just introduced several such games with an extensive advertising campaign directed at people 10 to 25 years old, the age-group most likely to play video games. It follows, then, that the sales of Whirlwind video games are likely to increase dramatically in the next few months."
2、The survey asked video-game players what features they thought were most important in a video game. According to the survey, players prefer games that provide lifelike graphics, which require the most up-to-date computers. 这句话的问题在于游戏者看重游戏的画质并不表示游戏者会选择画质比较好的游戏,或许有别的游戏者看重的方面。比如游戏性,剧情等等。
3、Whirlwind has just introduced several such games with an extensive advertising campaign directed at people 10 to 25 years old, the age-group most likely to play video games. 这句话隐含的前提就是有extensive advertising campaign和买游戏的人喜欢画质好的游戏,这种游戏就会令销量上升。这两个assumption都是有问题的。影响游戏销量的因素很多,大众的经济因素,游戏销售的价格等等,并不能由上面的两个因素就说这样的游戏销量好。
