问题     Most of us would shy away from making purchases in a foreign country if we didn’t know the exchange rate. Yet, if privacy is the true currency of the Internet, as many argue, millions of us are doing that very thing every day. Meanwhile, Internet giants amend their privacy policies in ways that allow them to harvest and sell even more of our personal data. While privacy campaigners protest, users generally vote with their clicks and carry on regardless.
    So should we conclude the Internet generation is happy to trade its privacy for free or cheaper Web services? Not according to Nicola Jentzsch of the German Institute of Research in Berlin, and colleagues, who last week published research showing that most people prefer to protect their personal data when given a choice and that a significant proportion are willing to pay extra to do so.
    The researchers directed 443 students to a website offering tickets for a real movie showing, sold by two different vendors(商贩). Although the tickets were subsidized, the volunteers, who were able to purchase one, two, or no tickets, had to pay most of the cost themselves.
    When both vendors offered tickets at the same price but only one required customers to enter their cell phone number, the more privacy-friendly vendor got 83% of sales. When participants were offered the same choice, but with an additional charge of 50 euro cents from the privacy-friendly cinema, its market share fell to 31% .
    " It turns out that when you are good on privacy you can charge more and make a greater profit," says Alessandro Acquisti of the University of Cambridge, one of the authors of the study, published by the European Network and Information Security Agency.
    " What people say in surveys is that they care about privacy, but what they actually do is spend their time constantly updating their status on Facebook," says Acquisti. " This has led some to conclude that people no longer care about privacy. This new data, along with similar work we have done in the U. S. , shows this is not the case, and that the desire for privacy is not dead after all. "
What is the author’s purpose of writing this passage?
选项 A、To promote understanding between vendors and consumers.
B、To argue that the Internet generation still cares about their privacy.
C、To persuade people not to constantly update their status on Facebook.
D、To urge vendors to be more privacy-friendly to make a greater profit.
答案B
解析 主旨大意题。本题考查整篇文章的主旨大意。作者的写作意图一般在文章首、尾两段交代。原文末段作者引用艾奎斯蒂的话说，人们仍然有保护自己隐私的意愿，且文章中引用的研究都证明了这一点，故作者写这篇文章的意图是要证明互联网一代仍然在乎自己的隐私，故答案为B)，由此可排除A)“为了促进商贩和消费者之间的理解”、C)“为了说服人们不要不断地更新脸谱网上的状态”和D)“为了敦促商贩们更加注重保护顾客隐私以便盈利更多”。
