雅思多项选择题分为7选3和5选2，答案并没有顺序限制，这两类选择题可以用以下两个方法来解决。

排除法

排除法主要应用在选择题的选项在录音中全部出现，也就是干扰选择很多的题目中，以下面这道题为例，我们来讲解如何在实际中运用排除法解题：

【剑桥8 test1 section 2 19-20】

Which TWO activities can students do after the tour at present?

A. Build model dinosaurs

B. Watch films

C. Draw dinosaurs

D. Find dinosaur eggs

E. Play computer games

根据题干的限定词after the tour at present，在审题时就应该判断出来此题会出现干扰选项

原文：on the ground floor there are continuous screenings of short documentaries about dinosaurs which you can see at any time……这时理解力能力强的同学会对应到B选项 watch films

没理解的同学别着急，我们继续往下听：

we used to have an activity room with more interactive things like making models of dinosaurs and drawing and painting pictures, even hunting dinosaur eggs,听到这三个选项A,C,D并列可以根据并列排除法直接都排出来，或者根据used to have 与at present题干限定冲突全部排除，如果没反应过来继续听，会听到but unfortunately the room was damaged 更可以确定以上答案排除。

接着录音提到we do have an IT center where students have access to CD ROMs with a range of dinosaur games. 同意转换反应快的同学会对应到E.

所以通过录音的同意转换或者排除就可以选出正确选项B E了.

答案替换法

替换法应用的题目主要是选择题的选项在录音中只出现2至3句的情况，这类选题出现得不是很频繁，并且难度不大。

例题：【剑桥4 test 2 section3 25-26】

What TWO disadvantages of the questionnaire from of date collection do the students discuss?

A. The data is sometimes invalid

B. Too few people may respond

C. It is less likely to reveal the unexpected

D. It can only be used with literate populations

E. There is a delay between the distribution and return of questionnaires.

此题让选两个questionnaires的disadvantages.在录音说了大量废话后，然后出现I’m sure it talked about drawbacks as well.注意：Drawback =disadvantages，限定词出现之后，紧接着出现答案：something about the response rare and the problems you get if it’s too low. 对应B选项;another drawback I remember it mentioned was that questionnaire data tends to not to reveal anything unexpected对应C选项。
