雅思阅读考试的目的是考察考生通过*话题文章的阅读定位所需信息，理解、掌握并获取知识的能力，而其中定位词扮演着至关重要的角色。朗阁海外考试研究中心发现有很多考生抱怨说“题目特点和解题技巧都很清楚，定位词也能找准，可就是定位不到题目在文章中对应内容的位置”。
★ 雅思定位词在文章中出现的种也是*常见的一种变身是“同义替换”，这包含同义词或同义词组。
剑6, Test4的Q9: Kim Schaefer’s marketing technique may be open to criticism on moral grounds。题目中定位词为moral, 在文章中定位，我们会在文章第三段中定位到“Selling pharmaceuticals is a daily exercise in ethical judgment”，而其中ethical即为moral的同义词。
剑4, Test3的Q9: Any street child can set up their own small business if given enough support.此判断题中定位词实际上是词组“set up their own small business”, 在文章中定位，我们会在文章中“Lessons learned”的部分中定位到“Being an entrepreneur is not for everyone, not for every street child”。此处，文章中“Being an entrepreneur”即为定位词的同义词组。
其他的同义词/词组变身如：
perceive →sense evolve →develop detect →find
mortal →people unbiased → objective
limb → arm or leg waste→ unwanted material
resemble → look like dwelling → domestic building

其他的近义词/词组变身如：
salary → wage statement → comment
be gained from → derive from policy → initiative
valuable → important break down → subdivide
★ 雅思定位词在文章中出现的第三种变身是“派生词”。
剑6, Test3的Q33: Monkeys were less likely to become diabetic。此题为分类题，定位词为“diabetic”, 在文章中定位，我们能定位到句子“…and they have more normal blood glucose levels(pointing to a reduced risk for diabetes, which is marked by usually high blood glucose levels)”。题目中定位词“diabetic”为名词，意为“糖尿病患者”，而文章中的“diabetes”也为名词，但意为“糖尿病”，是“diabetic”的派生词。
剑4, Test4的Q14: archaeology involves creativity as well as careful investigative work。 此题为是非无判断题，定位词为“creativity”和“investigative”, 在文章中我们能定位到“Archaeology is partly the discove
