雅思听力--学术选择的对话逻辑关系

熟悉雅思听力的同学们都知道，雅思听力总共分成4个部分，每个部分来说在题型以及难度上讲也是不同，尤其是s3部分，结合近几年的考试来看，大部分情况出现题型以选择题为主。s3选择题由于本身文章以及题目相对较长，同时又结合较难的同义替换，很多同学在做题中总是会毫无头绪。对此，我们可以结合s3以及选择题型特点来进行处理。 

首先在雅思听力中s1以及s3部分基本都是以对话结构出现，尤其是s3部分的文章一般以校园学术对话为主，且大部分文章的对话人数为2人为主（偶尔存在3人对话文章）。所以校园学术对话从对象上来说基本存在两种情况：

1. 师生对话 ，一般为学生课题遇到问题去请教老师； 

2. 两个学生一组做一个project，相互讨论相关内容。我们可以先来看一个简单的例子来弄清楚对话逻辑。

在C11T2S3这一篇Helen 与 Colin两位学生课题讨论的文章中：

在用题干中的“aim”定位之后，Colin先通过“ But we need something about what causes different organisms to choose particular habitats.” 提出自己建议，在选项中对应为A，这时候建议学生在做题时可以先定位到该选项，但记住文章对对话结构，所以必定要去听取另一对话对象的态度，随即Helen给出的态度为“ I agree”，即肯定态度，这时才可确认正确答案为A。

Helen之后也提出“And something about finding out how to protect organisms in danger of dying out?” ，即B选项，一样的道理，之后Colin的态度也是很明确的一个否定，所以也将误导选项B排除。

Colin: I just put something about getting experience of the different sorts of procedures used on a field trip. But we need something about what causes different organisms to choose particular habitats.

Helen: I agree. And something about finding out how to protect organisms in danger of dying out?

Colin: In our aims? But we weren’t really looking at that.

21. what do the students agree should be included in their aims？

A. factors affecting where organisms live

B. the need to preserve endangered species

C. techniques for classifying different organisms

同理：在C10T2S3两位学生讨论考古学家Thor Heyerdahl的文章中，学生Olivia在定位到之后先讲到“ do you think it was important to him that he achieved it before anyone else did ?” 对应同义替换选项为A，但紧接着Victor提到态度：“um, i haven’t read anywhere that was his motivation” 否定了该选项，同时” the most important factor seems to have been that he only used ancient technique and local materials to build his raft” 即C选项，Olivia随记肯定：“yes” ，所以得出正确选项C。

27. What was most important to Heyerdahl about his raft journey?

A. the fact that he was the first person to do it

B. the speed of crossing the pacific

C. the use of authentic construction methods

小结：所以灵活运用对话逻辑结构，确认对方态度在做对话类文章中能够帮助同学们在处理学术类选择时能够更加清晰明了句子与选项的关系，同时结合排除法帮助排除误导项，帮助确认正确答案。

最后希望每一位要雅思备考路上的同时都能早日成功，拿到理想成绩！
