实例解析雅思阅读定位词的三十六变

　　★ 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

　　★ 雅思定位词在文章中出现的第五种变身是“上义词/词组”。

　　剑6，Test3的Q28：Studies show drugs available today can delay the process of growing old。此题为是非无判断题，定位词为“drugs”，在文章中定位，我们能在文章第一段定位到“As researchers on aging noted recently, no treatment on the market today has been proved to slow human aging –the build-up of molecular and cellular damage that increases vulnerability to infirmity as we get older”。文章中“treatment”即为定位词“drugs”的上义词。

　　剑4，Test2的Q8：Young people often reject the established way of life in their community。此题为人名理论配对题，题目中信息量较大，需要根据词组“reject the established way of life in their community”来定位，到文章中定位，我们会定位到“When the next generation reaches their teens, they might not want to be induced into the old traditions”。此处，“the old traditions”即为题目中“the established way of life in their community”的上义词组。

　　其它的上义词/词组变身如：the newspaper and television → media
