In advertising various strategies are used to persuade people to buy products. In order to sell more products, advertisers will often try to make us believe that a product will meet our needs or desires perfectly, even if it’s not true. The strategies that they use can be subtle, friendly forms of persuasion that are sometimes hard to recognize. In a lot of ads, repetition is a key strategy. Research shows that repeated exposure to a message, even something meaningless or untrue, is enough to make people accept it or see it in a positive light. You’ve all seen the car commercials on TV like, uh, the one that refers to its roomy cars over and over again. You know which one I mean. This guy is driving around and keeps stopping to pick up different people. He picks up three or four people. And each time, the narrator says, “Plenty of room for friends, plenty of room for family, plenty of room for everybody.” The same message is repeated several times in the course of the commercial.
Now the car, the car actually looks kind of small, it’s not a very big car at all, but you get the sense that it’s pretty spacious. You’d think the viewer would reach the logical conclusion that the slogan mis-represents the product, instead, what usually happens is that when the statement “plenty of room” is repeated often enough, people are actually convinced it’s true. Um, another strategy they use is to get a celebrity to advertise a product. It turns out that we’re more likely to accept an advertisement claim made by somebody famous, a person we admire and find appealing. We tend to think they’re trustworthy. So, uh, you might have a car commercial that features a well-known race car driver. Now, it may not be a very fast car, uh, it could even be an inexpensive vehicle with a low performance rating. But if a popular race car driver is shown driving it and saying, “I like my cars fast!” Then people would believe the car is impressive for its speed.

? 中开头，教授指出讲座的主题是关于广告中有许多战略用来说服人们购买商品。为了卖出更多的产品，广告商往往会试图让我们相信产品将满足我们的需求或渴望，即使这不是真的。从关键词various strategies are used to persuade people推断出，该讲座主题属于方法一类，因此可以推断，教授在下文将介绍几种广告行业中运用的战略。
中以… is a key strategy的句型指出第一种战略方法是repetition，即重复。?中以another strategy …的句型引出第二种是通过celebrity来做广告，即名人。
?中教授用You’ve all seen引出car commercials(汽车广告)的例子说明这个战略方法是什么。教授用like, uh, the one that 指出roomy cars是一直被重复的一个信息，广告中反复plenty of room来突出汽车空间非常大。?中又更近一步指出实际上这辆车看上去并不大，由于plenty of room一直被重复，人们会相信这是事实。
?中用So引出celebrity(名人)的例子来说明第二个战略方法。?中详细举例well-known race car driver，利用著名赛车手的例子展开描述。?中提出即使车辆本身不贵、性能评价也不高，但是赛车手在代言此汽车广告的时候说到I like my cars fast，那么人们会对这辆车的速度印象深刻。
