Part B:长对话(Longer Conversati##被过滤##) 　　
考试当天你将会碰到如下的答题提示：　Directi##被过滤##: In this part of the test you will hear longer  conversati##被过滤##. After each conversation you will hear several questi##被过滤##. The  conversati##被过滤## and questi##被过滤## 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. 　　
策略：逆向搜索法不太适合较长的对话和段落题,因为每个段落的后面接下来有3至4个问题.充 分利用Direction旁白时间,尽量事先浏览一下答案的选项,对这篇文章中会用到的一些词汇有 个提前的熟悉。 　　
策略1： (针对听力能力较差的考生)当磁带在放的时候,闭上你的眼睛全神贯注于对话的主题(中 心思想),不必担心你没有每个词都听懂,尽量去理解这个对话是关于什么的,说话的人是谁,然 后根据你对文章大意的把握答题。 　　
策略2： (针对听力能力较高的考生)当磁带在放的时候,听对话或演讲的大意,同时留意细节.注意 特别的人，物，地点和事件.同样要想说话的人是谁,他们的关系是什么.因为后面出题时经常 用原字或者原词(一般不会用不同的词，即同义词复述).这一部分的难度很大程度上来自记住 所有的细节，因为考试时规定你不能做记号。所以当你练习的时候要注意训练这种能力。(当 然你要是写一点记号也是可以的,做完题后擦掉就行了。)

1999年1月Part B考题(第31-34题) 　　PART OF A TELEPHONE INTERVIEW 　　
* Dr. Thomas? This is Keet Bradley from the daily news. I'd like to ask  you some questi##被过滤## 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 resp##被过滤##ibility to see that all the scales  measure a kilogram accurately 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 porous. 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 cost? 　　
* 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?  　　
(A) How to care for precious metals. 　　(B) A standard unit for measuring weight. 　　(C) The value of precious metals. 　　(D) 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。因为一 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。首 先，Daily news的职员(记者)电话采访Dr Thomas。即使你的听力不是很好，你也能听到首 音节重读的单词standard。接着，又出现了许多与尺度有关的词，如weight，measure， scale。所以，我们可以肯定他们在谈关于选项B中的“衡量重量的标准单位”。 复述题? 　　例题：How was the weight used?  　　
(A) To check the accuracy of scales. 　　
(B) To calculate the density of other metals. 　　
(C) To observe changes in the atmosphere. 　　
(D) To measure amounts of rainfall.? 　　答案是A。复述题只是对对话中原句用同义词的改写甚至就用原句照搬到选项中。在这一 题中，即使你不知道the weight到底是什么东西，你也可以猜测它应该指代the standard  weight(标准称)。对话中曾经出现
