三、实例讲解（选自2020年医学博士英语样卷） 1.A. Food packagingB. Safety of processed foods C. Concern about sugar intakeD. Maintenance of a healthy diet 2.A. RedB. Orange C. GreenD. Brown 3. A. IndifferenceB. Resentment C. OverreactionD. Undervaluation
第二步：听音重点和记录内容。 根据常见听音重点内容，结合上述预测方向，更针对性听取重要内容。 第一题听文章开头或全文逻辑: “I’m always seeing the news these days that we’re eating too much sugar. And one important factor is that sugars are sometimes hidden in processed foods.” 第二题记录各颜色关联的信息: “Red for high levels of sugar, salt or fat, orange for medium, and green for low.” 注意最后问题具体问及哪个颜色。 第三题记录态度内容: “M: That sounds helpful; W: But one problem we see in nutrition is sort of this focusing on any individual foods. Sugar is demonized. People link it to drugs. And I think this is the wrong way forward.”注意转折之后的内容，并注意最后问题具体问及男性还是女性的态度。
第三步：确定答案。 第一题：“对话中主要讨论了什么?”文章开头则提及“我们吃太多糖了，而且糖有时隐藏在加工食品中”。后文则提及怎么寻找糖分在食品中的比重信息等，则C项正确。 第二题：“哪一种颜色表示糖含量低? ”根据“green for low 绿色表示（糖分）低”可知C项正确。 第三题：“根据这位女士的说法，人们对糖的态度有什么问题?”因此，根据“People link it to drugs. And I think this is the wrong way forward.人们把它与毒品联系起来。我认为这是错误的方向。”可知，C项正确。

M: That sounds helpful. W: But one problem we see in nutrition is sort of this focusing on any individual foods. Sugar is demonized. People link it to drugs. And I think this is the wrong way forward.
