雅思阅读之难破的词汇关首先我们来给同(反)义词下个定义：释义相同(反)的词。如： attraction 和 allure 虽然词性不同但我们仍然称它们为同义词。同样， essentially 和 unnecessary 称为反义词。同根词指的是一个单词的所有词性的组合, 如: value, valuable, invaluable, valueless. 可见这里的定义是泛泛的，是为了很好的考试而进行的 粗糙却很受用 定义。 了解了词汇的考核形式，下面笔者就雅思阅读中典型的词汇换用举几个例子： 例一： 原文：In Europe, the obstacle has been conservative local authorities and developers who prefer to ensure quick sales with conventional mass-produced housing. 题目：Many developers prefer mass-produced houses because they... 答案：sell quickly 解析：原文和题目中的句意关键词 developer, prefer 均相同，但 housing 换成了 houses, 即同根词的代换。 they 指代 houses， 又因为 because 应该引导从句，所以答案为动词短语。 quick sales 对应的动词短语为上述答案， 也就是说答案也是根据同根词替换而来的。 例二： 原文：While this includes complex kingdoms, as in Africa, and ancient empires, such as those of the Americas, the primary focus of attention in the twentieth century has been on small-scale societies. 题目：The twentieth-century collections come mainly from mainstream societies such as the US and Europe. 答案：FALSE 解析：原文与题目对比出现了一组反义代换词 small-scale societies 和 mainstream societies. 例三： 原文：Countries all over the world are actively promoting their wilderness regions to high-spending tourists. The attraction of these regions is obvious: by definition, wilderness tourism requires litter or no initial investment. 题目：The low cost of setting wilderness tourism makes it attractive to many countries. 答案：TRUE 解析：low cost=little or no initial investment; attractive 为 attraction 的同根词代换。 例四： 原文：In their new location, the beekeeper will pay the farmer to...
