托福听力部分主要考查考生是否具备听懂对话和讲座的能力。考生不但需要听懂主旨，还要听懂细节的内容以及说话人的态度。
想要在这部分获得高分，掌握大量词汇是必要的。然而许多考生虽然背了很多单词，但在托福听力考试中仍然无法取得理想分数。那么，这究竟是哪些原因造成的呢？
在口语中，有些单词在读音上可能会出现变化，比较常见的有连读和吞音现象，如kind of有时会发成kinda ；got have to则常简化为gotta 。
另外，还有一些单词比较口语化，而且通常只在口语环境中使用。如果不熟悉这类单词的用法，也有可能造成失分。请看下面的例子：
然后，考生会听到以下录音：
Professor Remember how I showed you in the lab, one little seed starts out producing one little shoot…three weeks later you've got about fifteen shoots coming out all directions like this—all those little shoots up there?
Well, that's what they did with rye…When they looked at the shoot versus the root surface, they found that the shoot surface, with all of its leaves, had a total surface area of about five squares meters. Now, here's the biggie, when they looked at the root surface area, you would expect that the root and the shoot would be in balance, right? …
Male Student Uh-un.
Professor What's that? Did somebody say “no”? Well, you're absolutely correct…
如果考生了解biggie这个词，就会知道它后面的内容一定是比较重要的。根据Now, here's the biggie, when…及上下文的内容，就可以排除C选项。
我们为你解决口语单词用法的难题：
在做听力题目时，如果不理解特定单词的意思，那么不管它是出现在听力内容中，还是出现在题目里，都会对理解造成影响。请看下面的题目：
听力文本如下：
Professor Exactly. It's a written letter not a conversation, but the principle is the same. The boss is conveying a negative impression of Mr. X without actually saying negative about him. So, by violating the maxims, we…eh…but…it can be a way to be subtle or polite, or to convey humor through sarcasm or irony. Sometimes though people will violate maxims for another purpose: to deceive. Now, can you imagine who might do such a thing?
Student Some politicians.
Student Or advertisers.
Professor Right. Anyone who may see an advantage in implying certain things that are untrue without explicitly saying something untrue. They think, hey, don't blame us if our audience happens to draw inferences that are simply not true. So next time you see an advertisement saying some product could be up to 20% more effective, think of these maxims of quantity and relevance, and ask yourself what inferences you are being led to draw. Think, more effective than what exactly? And why do they use those little phrases ‘could be' and ‘up to'? These claims give us a lot less information than they seem to.
这里教授举了广告的例子，因为广告常以模糊而中肯的语言误导消费者。如果考生不了解relevance有“中肯”的含义，就无法选对答案。
我们为你解决词义不熟悉的难题：
托福听力考试中不会涉及太过专业的知识，但在谈论特定话题的时候，就会涉及大量相关的单词。如果考生知道这些单词的含义，那么理解材料的大意通常不成问题。如：
录音文本如下：
Professor Right. In astronomical units—not perfect, but tantalizingly close. The value of Mars is off by…6 or 7 percent or so… Then Jupiter's right there at 5-point something, and then Saturn is about 10 astronomical units from the sun. Um, well, this pattern is known as Bode's Law.
…
Well, you can imagine that there was some interest in why the 2. 8 spot in the pattern was skip, and um…but there wasn't anything obvious there, in the early telescopes. Then what happened in the late 1700s? The discovery of…?
Female Student Another planet?
Professor The next planet out, Uranus—after Saturn.
根据学生询问的Another Planet?可以知道一颗行星被发现了。如果学生不了解asteroid, astronomical, planet等词，就可能无法选出正确答案B。
