16.We all know that certain oils are healthier than others.but your oil health goes beyond just the type.The health of your oil can be related to how you use it too.Each type of oil has what is called a"smoke point."The smoke point is the specific temperature at which the oil starts to break down,or in more technical terms,its molecular structure begins to change.These molecular changes result in; changes in flavor,as well as changes in nutritional value,specifically,the nutritional value of the oil starts to reduce;changing what once may have been considered an especially healthy oil,like Olive,into one that is unhealthy.
The higher an oil's smoke point is,the higher the temperature of the oil can be.As a result,each type of oil should be used for the cooking method that is most appropriate to its individual smoke point and heat tolerance.Here is a quick guide for the next time you reach for your favorite oil.

分析 本文属于说明文阅读,作者通过这篇文章主要向我们介绍了油的烟点和每种类型的油都应用于最适合它的个别烟点和耐高温的烹调方法,作者旨在告诉我们某些油是健康的"这个观点是相对的.
解答 62.D.细节理解题.根据文章第一段"but your oil health goes beyond just the type.The health of your oil can be related to how you use it too"油的健康不仅仅是类型,也取决于你如何使用它;可知你如何使用它决定了油是否健康;故选D.
63.C.推理判读题,根据表格可知制作沙拉需要的是未经提炼的低热度的油,根据表格可知符合题意的只有未经提炼的橄榄油;故选C.
64.B.细节理解题.根据文章第二段"These molecular changes result in; changes in flavor,as well as changes in nutritional value,specifically,the nutritional value of the oil starts to reduce"这些分子变化的结果;风味改变,以及改变的营养价值,特别是对油的营养价值开始减少;可知是油变不健康的方法是加热超过烟点;故选B.
65.C.推理判断题.根据文章第二段"As a result,each type of oil should be used for the cooking method that is most appropriate to its individual smoke point and heat tolerance"因此,每种类型的油都应用于最适合它的个别烟点和耐高温的烹调方法;可知作者想告诉我们某些油是健康的"这个观点是相对的;故选C.
点评 考察学生的细节理解和推理判断能力,做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确的选择.在做推理判断题不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.
