雅思阅读定位词★ 雅思定位词在文章中出现的第一种也是最常见的一种变身是“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
雅思阅读定位词★ 雅思定位词在文章中出现的第二种变身是“近义替换”，这包含近义词或近义词组。
剑7，Test1的Q8：However, even before this was understood, the principle had been applied in the design of instruments which calculated the ____ of the seabed。 此题为在原文中选词填空的摘要题，定位词为“calculate”和“seabed”， 在文章中我们会定位到“Before this was discovered, engineers had already built instruments to exploit the principle, for example to measure the depth of the sea under a ship”。此处“measure”即为“calculate”的近义词，而“sea”即为“seabed”的上义词。
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
雅思阅读定位词★ 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 discovery of the treasures of the past,…partly the exercise of the creative imagination…it is investigating the sewers of Roman Britain”。题目中定位词“creativity”为名词，在文章中对应形式“creative”(形容词)为它的派生词，;定位词 “investigative”为形容词，在文章中对应形式“investigate”(动词)为它的派生词。
其他的派生词变身如：
recover → recovery evolutionary → evolve
erosion → erode
雅思阅读定位词★ 雅思定位词在文章中出现的第四种变身是“反义词的否定形式”。
Sticking Power中的Q15：What makes sticky insects feet special is the fact that they can also detach themselves easily from a surface。
此题属于人名理论配对，题目中定位词为 detach。到文章中去定位，我们会定位到“’There are lots of ways to make two surfaces stick together, but there are very few which provide precise and reversible attachment’ says Stas Gorb”，句中attachment实际上为detach的反义词attach的名词形式，而reversible表示可逆的，因此 reversible attachment即为detach的反义词(组)的否定形式。
其它的反义词否定形式变身如：similar → not unusual
