听力原文：Anna Hi, Jack. Jack Hi, Anna. Anna Are you free now? Jack Not too busy. What can I do for you? Anna I wanna discuss with you on the lecture the professor gave at the last class. Jack Oh, that was an interesting lecture, wasnt it Anna Yeah, that is why I am still thinking about his views. Jack So, what is your opinion on the topic of marketing? Anna Marketing merely reflects the needs and wants of consumers. Marketing deals with identifying and meeting human and social needs. Successful goods, including products and services, are those that are demanded or needed by consumers. That is the summary of the views in our textbook. Is that right? Jack Er, those are the views in our teaching materials. Anna Well, I think that marketing can sometimes shape consumers needs and wants. It helps us in making major decisions like what car to buy; what realtor to use; to not so major decisions like what computer to buy, where to shop for clothes, groceries etc. Jack Uh...for instance... Anna regaining train of thought Er, the marketer that uses the catchiest phrases; the funniest ads; the latest music in their ads and or the coolest celebrities in their ads, are usually the ones that get our attention...We tend to buy for some of these reasons, and so this proves that our needs are shaped by marketing. Jack Uh... thinking Hmmm... that sounds reasonable. Anna So... Jack But, I think buying from one retailer over another, because their marketing is better or more convincing is not saying that the marketer is shaping or creating a need though. Anna Oh? Why? Jack The need or want is established already in the buyers mind. It is up to the marketers to make their product stand out among the competition, so that you, satisfy your need with their product. Anna Uh... thinking Er...although marketing has been defined as satisfying customer needs and wants, I tend to agree with the critics. Marketers sometimes have 'tremendous' swaying powers on encouraging consumers to spend more money than they should on goods or services that they simply do not need. Jack That is interesting, go on. Anna You see, I dont need a new computer, but Microsoft has a more updated one thats much faster and 'it will make my life so much easier' (so they say). I have a 1999 Mazda. It runs fine, but the advertisement for the new 2005 Mazda is sticking in my mind. Will I buy that new Mazda 626, hmmm? Jack Excellent. You seem to have thought about the topic deeply. Next class, you can discuss it with the professor, then we can hold a debate. Anna leaving Great. I think other students will also be excited to discuss the topic. I wanna go to the library to find reference books for the discussion. Bye! Jack Okay, bye!Narrator Listen to part of a conversation between to students. Now get ready to answer the questions. You may use your notes to help you answer. Why does Anna go to see her classmate?
