本次解析针对新托福口语考试Task 6进行讲解，在上一次的机经解析中，我们为大家展示了新托福口语考试第六题的使用技巧和解题思路，今天的讲解中，我们为大家提供第六题的更多sample。第六题是整个综合口语题目中最难的，通常来说，概括这个题目的要求还比较多，如果只答出了一部分内容，可能会丢掉些分数。困扰大家的几个难点在于：1. 第六题是讲座，涉及的话题比较学术，学生对话题的内容和词汇较陌生；2. 内容长，例子多，句型复杂，所以概括起来难度较大，时间不好掌控。对于这样的题目，对英语听力能力和概括能力要求较高，如果我们不能利用好机经的话，在无准备的情况下直接听，得到理想分数是比较难的。因此如何使用机经就显得尤为重要了，请大家注意学会使用机经的方法，然后自己举一反三地练习和丰富机经的英文版本。
