大家熟知，托福听力的题型都是选择题，不过我们又可以把其化分为三个大类：单选题、多选题及表格题。多选题在近年的考试中出现的频率逐年增加，部分篇章甚至会出现2道多选题。
多选题顾名思议答案不只有一个，多选题有两种，第一种是四选二，第二种是五选三，90%情况出现的是四选二多选题。
这类题型是大部分同学非常头疼的一种题型，很容易出现只选对一个选项的情况，而听力文本中出现列举的地方是最有可能出多选题的。
那么在对话和讲座过程中我们如何去把握对应的考点，并做到积极预测这种题型，这就是作为考生的我们需要把握的关键！
上海环球教育黄思薇老师认为多选题的考点可以通过以下两种逻辑结构去把握：第一、并列结构；第二、离散结构。并列结构所占的比例达到了95%以上，而离解结构一般不常出现，这种结构最大的难点在于我们并不能从一句话或一个段落中的并列结构去判断，需要总结原文所涉及到的对应内容。
并列结构的考点经常会出现一些起到提示作用的信号词，因此咱们在听到这些信号词时要做出迅速反应，积极预测是否会出多选题。
第一类信号词是一些并列词，比如：and, also, another, other, plus, not only… but also等；
例题：TPO15 - C2
3. What does the student need to do before he can use any rare books? Click on 2 answers.
a. Purchase a card
b. Obtain permission
c. Put on gloves
d. Try interlibrary loan service
对应原文：You need to get special permission to access them, and then you have to wear gloves to handle
解析：老师对学生说要使用rare books首先必须得到特殊的许可，咱们听到了permission这个单词，对应的是B这个选项；and then表示并列的词引导出第二个要求wear gloves，咱们又听到了gloves这个单词，对应的是C这个选项。所以答案是BC。
第二类信号词是一些数量词，比如：the first, the second等；
例题：TPO 24 - L4
2. How were scientists able to learn new information about Venus' surface? Click on 2 answers.
A. More powerful telescopes allowed astronomers to see more surface details.
B. Satellites were used to get radar images of Venus's surfaces.
C. Space modules sent photographs after landing on Venus.
D. A space probe was able to locate gaps among Venus' clouds.
对应原文：First of all, let me talk about how we have been able to get past those clouds. First, there were Soviet modules that landed directly on the surface and sent back some images of what was around them. Second, we did some radar imaging from satellites from above.
解析：教授说让我们来探讨如何穿过那些云层的，首先我们听到了第一个信号词first， 接着我们听到了modules这个单词，刚好对应的C选项；接下来我们听到了第二个信号词second，接着我们听到了radar imaging from satellites，radar这个单词对应的是B这个选项。所以答案是BC。
第三类信号词是一些名词：比如：factors, reasons, categories, elements, different kinds等；
例题：TPO7 - L4
4. What factors are involved in the amount of deformation a glacier undergoes? Click on 2 answers
A. The thickness of glacial ice
B. The hardness of glacial ice
C. The amount of water beneath the glacial ice
D. The temperature of the glacial ice
相应原文：Now, there are a couple of factors that affect the amount of deformation that takes place or the speed of the glacier's movement for example. Deformation is more likely to occur the thicker the ice is, because of the gravity of the weight of the ice. And temperature also plays a part here, in that cold ice does not move as easily as ice that is close to the melting point.
解析：在这道题目当中，教授先用a couple of factors这样的总分结构引入下面的分论点，然后说了2个影响冰川变形量的因素，以并列连接词also连接，第一个是the thicker the ice is, 第二个是temperature,所以答案应该是AD。
所以考生在听的过程中首先要有考点的意识，其次要对信号词足够的敏感，能够做到迅速识别考点，并且预测多选并列的可能性，这样才能夯实基础，在考试中把握主动。
