题目内容：

  You’re in a department store and you see two fashionable young women, looking at a sweater. You listen to their conversation:

“I can’t believe it—a Lorenzo Bertolla! They are hard to find. It’s much cheaper than the one Sara bought in Rome.”

They leave and you go over to see this sweater. You’ve never heard of Lorenzo Bertolla, but those girls looked really fashionable. They must know. So, you buy it. You never realize that those young women are employees of an advertising agency. They are actually paid to go from store to store, talking loudly about Lorenzo Bertolla clothes.

Every day we notice what people are wearing, drinking and eating. If the person looks cool, the product seems cool, too. This is the secret of undercover marketing (秘密行销). Companies from Ford to Nike are starting to use it. It can reach people that don’t pay attention to traditional advertising. For example, consumers between the age of 18 and 34. They have a lot of money to spend, but they don’t believe ads.

So advertising agencies hire (雇佣) young actors to “perform” in bars and other places where young adults go. Some people might call this practice misleading, but the marketing manager Jonathan Reseller calls it creative. “Look at traditional advertising. Its effectiveness is decreasing”
