考试当天你将会碰到如下的答卷提示：
Directions: In this part of the test you will hear longer conversations. After each conversation you will hear several questions. The conversations and questions will not be repeated.After you hear a question, read the four possible answers in your test book and choose the best answer. Then, on your answer sheet, find the number of the question and fill in the space that corresponds to the letter of the answer you have chosen.Remember, you are not allowed to take notes or write in your test book.
方案
逆向搜索法不太合适较长的对话和段落题,由于每一个段落的后面下面有3至4个问题.充分借助Direction旁白时间,尽可能事先浏览一下答案的选项,对这篇文章中会用到的一些词语有个提前的熟知。
方案1
当磁带在放的时候,闭上你的双眼全神贯注于对话的主题,不必担忧你没每一个词都听懂,尽可能去理解这个对话是关于什么的,说话的人是哪个,然后依据你对文章大意的把握答卷。
方案2
当磁带在放的时候,听对话或演讲的大意,同时注意细节.注意特别的人，物，地址和事件.同样要想说话的人是哪个,他们的关系是什么.由于后面出题时常常用原字或者原词.这一部分的困难程度非常大程度上来自记住所有些细节，由于考试时规定你不可以做记号。所以当你训练的时候应该注意练习这种能力。
考试知识点及题型
中心思想题/场景题；复述题；暗示推理题。?
1999年1月Part B考试试题
PART OF A TELEPHONE INTERVIEW
* Dr. Thomas? This is Keet Bradley from the daily news. I'd like to ask you some questions about the new official standard weight that you purchased.
* I'd be happy to help you. What would you like to know?
* First of all, how was the standard weight used?
* Well, the people in our department use it to check the scales all over the country. The department of weights and measures, we are a government agency. It's our responsibility to see that all the scales measure a kilogram accurately1 so this is the way we use to adjust the scales.
* How did you check the scales before?
* We have an old standard weight that we used to use. It had to be replaced because it was imprecise. You see it was made of poor quality metal that was too porous2. It absorbed too much moisture.
* Oh. So when the weather was humid it weighed more and when it was dry it weighed less.
* Exactly. And that variation can affect the standards of the whole country. So our department had the new weight made out of higher quality metal.
* How much did it cosplayt?
* about 45 thousand dollars.
* 45,000 dollars? For one kilogram weight? That's more expensive than gold. Is it really worth that much?
* I'm sure it is. Industries depend on our government agency to monitor the accuracy of scales so that when they buy and sell their products there is one standard. Think of the drug industry, for example, those companies rely on high accuracy scales to manufacture and package medicine
中心思想题/场景题?
例题：
What is the conversation mainly about?
How to care for precious metals.
A standard unit for measuring weight.
The value of precious metals.
Using the metric system.
答案是B。显然这是一道中心思想题。在托福的听力中，中心思想题又叫场景题。由于一旦你能确定对话或者演讲的中心内容，你也就确定了该对话或演讲的场景；反之亦然。第一，Daily news的员工电话采访Dr Thomas。即便你的听力不怎么样，你也能听到首音节重读的单词standard。接着，又出现了很多与尺度有关的词，如weight，measure，scale。所以，大家可以一定他们在谈关于选项B中的衡量重量的规范单位。
复述题?
例题：How was the weight used?
To check the accuracy of scales.
To calculate the density3 of other metals.
To observe changes in the atmosphere.
To measure amounts of rainfall.?
答案是A。复述题只不过对对话中原句用近义词的改写甚至就用原句照搬到选项中。在这一题中，即便你不了解the weight到底是什么东西，你也可以猜测它应该指代the standard weight。对话中过去出现了check the scale，而文章的倒数第二句Industries depend on our government agency to monitor the accuracy of scales so that when they buy and sell their products there is one standard.也说明了the weight的作用。?
例题：Why was it necessary to replace the old standard weight?
Someone spilled water on it.
Someone lost it.
It was made of low quality metal.
The standard for measuring had changed.?答案是C。
对话中出现了poor quality metal如此的词句，而在谈到new standard weight时又用higher quality。显然，old standard weight不是poor quality metal就是not higher quality，两者都可以，由于得出的关于old standard weight的结论都是一样的，即低水平。
暗示推理题?
例题：What does Dr. Thomas probably think about the cosplayt of the new weight?
It is a small amount to pay for so much precious metal.
It is difficult to judge the value of such an object.
It is reasonable for an object with such an important function.
It is too high for such a light weight.
答案是C。这里，问题问Dr. Thomas可能如何看待new weight的本钱。对话中，Dr. Thomas并没直接说the cosplayt is good or bad。但大家却可以通过前后两句推出它觉得it is worthwhile，即一问一答Is it really worth that much?I'm sure it is.。
