Which of the following is true of the text？
A．Although the risk exists, the internet advertising still can earn a lot of profit,
B．The PPA will substitute the original click advertising model.
C．All operators start to satisfy the advertisers by using PPA.
D．The entrepreneurs are pleasantly surprised by the temporary solution.
答案
A
解析：文章第二段结尾：Google made most of its $6.1 billion in revenue last year from pay-per-click advertising．文章最后两段：A few months ago Mr. Gross pioneered an alternative to the pay-per-click model..."pay-per-action" (PPA)，a new model in which advertisers pay only if a click on an ad is followed by an action such as a purchase or a download...But Mr. Tobaccowala thinks pay-per-action could become a real alternative to pay-per-click．As bigger companies spend more on internet advertising...本题第二段结尾讲到Google通过点击广告赚到很多利润，而后三段论述点击欺诈问题，即公司利润的风险，所以A正确。根据文章最后两句话可以得知，按有效行为付费广告模式代替传统广告模式是有条件的，这意味着必须对点击欺诈进行打压。D选项中谈到的临时解决方案指的是PPA，但它能否带来惊喜还没有定论。文章中提到只有部分网络运营商开始或打算使用PPA，并非所有，因此C错误。谨记：含有绝对含义的选项往往错误。
