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.

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”根据材料内容选择最佳答案，并将其标号填入题前括号内。16．Why do the two fashionable young women make the conversation in the store?A．Because they want to buy the clothes.B．Because they are the owners of the store.C．Because they want to draw other customers’ attention.D．Because they are excited to find the clothes.17．What is Lorenzo Bertolla?A．The name of a clothing store.B．The brand name of a sweater.C．The name of a fashionable girl.D．The name of an advertising agency.18．The undercover marketing mainly aims at .A．teenagers B．the oldC．young adults D．young women19．According to the passage, which sentence is wrong?A．The two fashionable young women are hired by an advertising agency.B．Some companies begin to use the undercover marketing.C．The customers between 18 and 34 don’t believe the ads.D．The undercover marketing is not as good as the traditional advertising.20．What’s the passage mainly about?A．Lorenzo Bertolla clothes.B．Undercover marketing.C．Traditional advertising.D．Companies about Ford and Nike.  四、短文选词填空A．skin    B．communicate    C． method    D．schedule    E. affordWhen you hold a book in your hands, please stop and think. It is the result of thousands of years of human invention. First came the invention of writing. With it, people didn’t have to remember everything in their heads.
