　　剑7，Test1的Q8：However, even before this was understood, the principle hadbeen applied in the design of instruments which calculated the ____ of theseabed。 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 wasdiscovered, engineers had already built instruments to exploit the principle,for example to measure the depth of the sea under aship”。此处“measure”即为“calculate”的近义词，而“sea”即为“seabed”的上义词。

　　剑6，Test3的Q33：Monkeys were less likely to becomediabetic。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 bloodglucose levels(pointing to a reduced risk for diabetes, which is marked byusually high blood glucoselevels)”。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。

　　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”。
