【正确答案】
D
【答案解析】[听力原文] The U.S. Federal Reserve announced yesterday it was raising interest rates for the first time since 2006. Known as the Fed, it's America's central bank. It's led by Janet Yellen. Its job is to help stabilize America's financial system. The Fed makes moves to try to lower unemployment and control inflation, when the price of goods goes up too fast for people to afford them. Because the U.S. economy is growing, the Fed raised its key interest rate by a quarter of a percentage point, not much. But gradual rate increases are likely in the new year. That means you'll have to pay more interest if you borrow money, higher mortgage rates for home buyers, higher interest rates if you finance a car, higher student loan rates for people who get those in or after 2016. And eventually, savings accounts could earn a little more interest. What is the news report mainly about? 新闻开头提到，美国联邦储备系统于昨日宣布，它自2006年以来首次加息，下文简单介绍了美联储的职能，并分析了加息可能会给美国社会带来的影响，由此可知，该则新闻主要关于美联储的加息政策，D项符合此意，故为答案。
