It used to be that looking for a job meant pounding the pavement, knocking on doors and poring over help-wanted ads. But that's changing, thanks to the Internet.  [20] A new report by Georgetown University's Center on Education and the Workforce says, for college graduates, looking for a job is getting easier.
The report's lead author, Tony Carnevale, spoke to VOA, appropriately enough online, via Skype. "More than 80 percent of those jobs that existed, at any point in time, are available online."
At the height of the recession--when U.S. unemployment peaked at 10 percent, just a little more than two million jobs were being posted each month. [21] But as the recovery takes hold, Carnevale says the job picture looks increasingly bright.
"We're now at about 3.7 million job openings out there. By the time the recovery is done, we think we'll get to maybe five million job openings online."
That's great news for Georgetown Junior Jamil Hamilton. Only once has he ever applied in person for a job at a shopping mall.
"I think my generation--the idea of going door to door, out knocking and saying, hey are you hiring?—like that—doesn't exist anymore.., those days are gone, just go online. "
[22] Kim Dancy recently graduated with a Master's degree in Public Policy. She found her dream job as an education policy researcher. But she says finding the perfect job online takes a lot of perseverance.
"It can be really frustrating and it takes a long time, but if you applied for enough positions and really do your homework you will get somewhere."
The report's findings suggest careers in the so-called STEM fields--Science, Technology, Engineering and Math —provide the greatest opportunities, with salaries that range between 30 to 45 an hour. But for maximum in come and satisfaction, Professor Carnevale says workers must be prepared to move and change jobs at least every five years.
According to the lecture, what change has the Internet brought about?
【解题思路】四项中均出现了look for／find ajob。本题考查的内容与找工作有关，by和means提示，本题可能考查找工作的方式。
【解析】讲座开头部分提到，由于互联网的存在， “徘徊街头，挨家挨户敲门，关注急聘广告”这种找工作的模式已经改变了，乔治敦大学教育与劳动力研究中心最新发布的一份报告称，对于大学毕业生拳说，找工作正变得越来越容易。因此可以得出D项为正确答案。A项中提到的“关注急聘广告”和B项中提到的“挨家挨户敲门、询问”都是以往找工作的方式，不是互联网带来的改变，可以排除。讲座前面部分提到，“现有的职位中，80％以上任何时候都可以在网上找到”，但这并不是说大学生随时都能找到工作，故排除C项。
