有一道语文题让考生曲解成语，给出的例子是“度日如年”，曲解为日子过得快乐得和过年一样，让考生再想两个曲解成语的例子有一题出上联“博雅塔前人博雅”，叫学生以北大的景物对下联，着实难倒了不少考生从“酷”“粉丝”“小众化”“媒体”等十个流行名词中选择5个，来解释其含义。

清华大学：《汉书·艺文志》中有“小说家者流，盖处于稗官，街谈巷语，道听途说者之所造也……”先用中文解释其含义，再用英文概括其大意，并用英文评论其观点。

武汉大学2010年攻读博士学位研究生入学考试真题解1

武汉大学2010年攻读博士学位研究生入学考试真题解析Part I Reading Comprehension (2×20＝40%)Passage One【译文】亚马逊迫于出版社压力，放弃以9.99美元的价格出售电子书。

许多精装的畅销书售价是30美元，麦克米伦出版商认为电子书9.99美元的价格会降低这些畅销书的价值。

为了回应这场价格之争，亚马逊上周撤下了所有麦克米伦出版的书籍。

但是，亚马逊仅仅抵制了一周，便答应了麦克米伦的要求。

在周日的声明中，亚马逊向消费者辩护了自己的态度。

世界六大出版社之一麦克米伦出版社已明确地告知我们，不管我们态度如何，他们已下定决心转换代理模式，将畅销书和大部分精装图书的电子版本售价调整为12.99美元至14.99美元不等。

我们强烈地反对这一决定，并且通过暂时停止出售麦克米伦出版的书籍来严肃地表明反对态度。

我们希望大家知道由于麦克米伦对其出版书籍的垄断，我们最终必须向麦克米伦认输并接受其条约。

即便我们认为电子书籍不需要这么高的价格，我们仍然想将这些书籍呈现给你们。

亚马逊决定妥协和麦克米伦授权苹果在其iBookstore售卖电子书的协议有关。

亚马逊占有电子书市场的绝大多数份额，但是如果iPad成功了，出版商可能授权苹果售卖他们的电子书。

相比于竞争电子书市场，出版商貌似对保护硬皮书的价值更感兴趣。

电子书价格的提高会促使你买纸质版的小说吗？或者鉴于电子书更便宜，你们会接受电子书价格的微微上调？【答案详解】1.【答案】A【注释】关于亚马逊与麦克米伦之间的价格战争哪种说法是正确的？文章第一句话“Amazon has given in to publisher pressure and agreed to abandon their $9.99 price point for eBooks.”说明亚马逊做出了让步，不再以9.99美元的价格售卖电子书。

因此A选项“麦克米伦赢得了此次价格之争”是正确的，B选项“亚马逊取得了胜利”以及C选项“双方均没有赢得价格之争”都是不正确的，而D选项“顾客很喜欢这次价格之争”文中并没有提到这一信息。
