首先是第四题各个环节的介绍：
Reading: (75-100 words): short passage about an academic subject---life science, physical science and the humanities (no outside knowledge is needed).
Listening: a professor gives a brief excerpt from a lecture on that subject.
Speaking: combine information in two sources.
虽然第四题的涉猎范围十分广泛，但并不要求考生具备任何课外知识，只要考生具有从材料中获得信息的能力，就可以回答第四题的问题。
在第四题的介绍(introduction)中，考生可以得到几个有用信息。在介绍的中部，考生可以得到第四题是关于哪个领域的相关信息(例如：sociology);在介绍的最后，考生可以得到与第四题文章内容相关的重要信息。例如：Using the examples discussed by the professor, explain what cognitive dissonance is and how people often deal with it.
下面，是第四题的阅读和听力材料的对比与分析。
对于听力材料，考生需要重点关注：
Topic
Major points
Examples
Causes (cause-and-effect relationship)
因为第四题的材料选择是学术型话题，逻辑比较严密，所以考生要特别关注材料中涉及到的因果关系。在口语回答时，考生也需要将材料中的因果关系解释清楚。
口语回答的要求：Orally summarize the lecture (key points and main examples).
网翟少成老师为考生总结了几条回答小贴士(useful tips)：
Find the KEY words as soon as possible and then write them down. This is to make sure that you will know what the professor is going to talk about.
Pay attention to the JARGONS(术语)in order to get familiar with the words that you don’t know before.
Do not panic if you don’t know anything about the subject, because your opinion is NOT included.
