托福听力 场景对话解析
托福听力真题TPO第一套的第四篇是课程场景对话。对话的整体思路和出题点分析如下。
对话开篇
本篇课程场景对话开篇是非典型的，属于教授针对自己感兴趣的话题找学生交谈，所以第一题主旨题的答案对应开篇教授说的"Hi Mathew, I'm glad you can come in today. You've been observing Mr. Grable's third-grade class for your approaches to education paper。"学生正在听课，第一题What is the conversation mainly about? 答案为 B. A class Matthew has been observing. Mathew正在听的一门课程。切记，听准开头做主旨题。
对话中间
两人展开Mathew听课之后的感受的讨论。Mathew用了一系列的积极向上的词来表达听课的感受，比如"amazing、 learning so much、so glad……I mean it's like the best thing ever to prepare you to be a good teacher."这里对应第二题What is Matthew's opinion about observing Mr. Grabell's third-grade class? 很明显答案为A. It will help him become a more efficient teacher. 可以有效帮助他成为一个能干的教师。这里既符合语义重复也符合最高级强调(the best thing)笔记法。
然后，教授提到It seems that Mr. Grable has mastered the interdisciplinary approach to teaching - the way we've been talking about in class.即课上讲过一种教学法IAT，后面听到的内容是对此教学法的解释。Matthew用到了举例子的讲课法，举了教授讲的天文学课程用到了mythology的知识，这里对应第三题Why does Matthew mention Greek and Roman mythology? 答案是D. To illustrate a technique used to teach a third-grade class. 为何提到举例主体，答案为例子出现前面的topic，即教授提到的IAT教学法。
接下来，Mathew谈到了学生在课上学习到的主要技能，And each student chose a planet and then did research on it to write a report and make a presentation. They went to the library to do the research, then they made presentations about the planet they chose.先做research，再写report，然后做presentation。
教授和Mathew再次重复这个信息，符合重复原则笔记法。对应第四题What important skill did Mr. Grabell introduce to his third-grade class?五选三，答案为 B. Using books in the library. D. Speaking in public. E. Writing reports.
对话结尾
结尾部分，教授对Mathew 提出建议"You know, Mathew, I'd love you to talk about this astronomy unit in class on Wednesday."Mathew开始并未答应教授的建议，后来同意了教授的建议，所以最后的第五题What will Matthew probably do in next Wednesday's class? 预测Mathew接下来可能做什么的答案为C. Make a presentation to the class. 将文中关键词talk同义替换为presentation。这是推断题考结尾段的引申的典型例子。
希望本篇解析可以起到抛砖引玉的作用，给备考托福的考生在对真题的理解上以启发。
