多选题 Representing a round world on a flat surface is impossible without some ______: the Mercator projection may shows Greenland as over ten times larger than Mexico, a country in fact only slightly smaller than Greenland.
【正确答案】 C、F
【答案解析】[解析] ●冒号表示前后同义重复；impossible without修饰空格，双重否定等于肯定。
●冒号后面的in fact体现了一种矛盾或者不合理，与空格对应。因此空格需填入一个表示矛盾或者表示不合理的词。
●oversight失察，simplification简化，distortion扭曲/歪曲，clarification澄清/净化，superficiality表面的东西/肤浅的东西，warping扭曲。答案选CF。
