③W： Here's a 10-dollar bill. Give me two tickets for tonight's show please.
M： Sure. Two tickets and here is '1，40 change.
Q： How much does one ticket cost?
A.'1.40. B.'4.30. C.'6.40. D.'8.60
10美元，两张票，找零1.40美元，说明每张票为4.30美元。
从以上例子可以看出，含有数量概念的题，对话中提到的数量一般不可能为正确答案，总要同学们进行一些简单的加减运算。
4)言外之意、弦外之音
推测说话者话中之话是听力中必考的题型。从试题的设计特点来看，大体有一下几种：
(1)对虚拟语气的考查
包含虚拟语气的听力考题中一般都有"是与非"相对的选项，这就要求同学们了解虚拟语气的表意功能，根据虚拟语气判断正确选项。 如：
①W： I'm thinking of going to Austin for a visit. Do you think it's worth seeing?
M： Well， I wish I had been there.
Q： What do we learn from the conversation?
A. The man is planning a trip to Austin.
B. The man has not been to Austin before.
C. The man doesn't like Austin.
D. The man has been to Austin before.
I wish I had been there.说明说话人没有去过。
②W： If it hadn't been snowing so hard， I might have been home by 9 o'clock.
M： It's too bad you didn't make it. Jane was here and she wanted to see you.
Q： What happened to the woman?
A. She got home before 9 o'clock.
B. She had a bad cold.
C. She had a car accident.
D. She was delayed.
If it hadn't been snowing so hard， I might have been home by 9 o'clock.说明因为雪太大，说话者未能在9点前到家。也就是说she was delayed.
(2)对建议的考查
建议题要求同学们掌握建议的各种表达方式，根据建议选择正确选项。如：
①W： The movie starts in 5 minutes and there's bound to be a long time.
M： Why don't we come back for the next show? I'm sure it would be less crowded.
Q： What is the man suggesting?
A. Coming back for a later show.
B. Waiting in a queue.
C. Coming back in five minutes.
D. Not going to the movie today.
Why don't…?上一种建议表达方式，根据该句所表达的内容可以判断答案是A.
②W： We do need another bookshelf in this room. But the problem is the space for it.
M： How about moving the old dining table to the kitchen?
Q： What does the man suggest they should do?
A. Finding a larger room.
B. Sell the old table.
C. Buy two bookshelves.
D. Rearrange some furniture.
根据moving the dining table to the kitchen来判断答案为D.
建议的表达方式还有：
Why not…? What do you think of…?
If I were you/If I were in your shoes， I would…
Shall we…? I suggest…。
You'd better/You ought to…。
(3)对话题的考查
话题指会话双方所谈论的话题，要求同学们具有概括能力。如：
①W： Do you want a day course or an evening course?
M： Well， it would have to be an evening course since I work during the day.
Q： What are they talking about?
A. The choice of courses.
B. A day course.
C. An evening course.
D. Their work.
两个人谈论的是选白天的课还是晚上的课，由此可以判断答案应该是A.
②M： I was terribly embarrassed when some of the audience got up and left in the middle of the performance.
W： Well， some people just can't seem to appreciate the real-life drama.
Q： What are they talking about?
A. A movie.
B. A lecture.
C. A play.
D. A speech.
从对话中的audience， performance与其说drama可以判断他们所谈论的是a play.
4)同义表达方式的考查
四六级听力测试中对隐含意思的考查很大程度上依赖于同义表达方式，也就是同学们对具体句式、短语、词组甚至单词的理解。如：
①M： What do you think of Professor Brown's lecture?
W： The topic was interesting， but the lecture was much more difficult to follow than I had expected.
Q： What does the woman say about the lecture?
A. It was a long lecture， but easy to understand.
B. It was not as easy as she had expected.
C. It was as difficult as she had expected.
D. It was interesting and easy to follow.
与much more difficult to follow than I had expected同义的应该是B.
②M： Nancy， why were you late today?
W： I overslept and missed the bus.
Q： Why was Nancy late?
A. She got up later than usual.
B. The bus was late.
C. She forgot she had class.
D. Her clock was slow.
overslept也就是got up later than usual.
③M： Did you mind coming back by coach instead of by train?
W： No， we didn't mind at all. It took a lot longer， but it was very comfortable and it was much cheaper.
Q： How did the woman feel about the coming back by coach?
A. She felt it was tiring.
B. She felt it was very nice.
C. She felt it took less time.
D. She thought it was expensive.
从comfortable和much cheaper来看，女士的感觉应该是very nice，答案应该是B.
(5)上下义概念的考查
有些题尽管问题可能问的是含义之类，但其实考查的是同学们对上下义关系的掌握。如：
①M： Let me see. I've printed my family name， first name， date of birth and address. Anything else?
W： No， that's all right. We'll fill in the rest of it if you just sign your name at the bottom.
Q： What has the man been doing?
A. Having an interview.
B. Filling out a form.
C. Talking with a friend.
D. Asking for information.
上义词为概括性词语，下义词所表示的则是具体的东西。本题中能够概括男士所做之事的应该是选项B.
②M： What happened to you? You are so late.
W： The bus I took broke down in front of the hospital and I had to walk from there.
Q： Why was the woman so late?
A. Something went wrong with the bus.
B. She took somebody to hospital.
C. Something prevented her from catching the bus.
D. She came on foot instead of taking a bus.
Something went wrong是对the bus break down的概括性表述。
