【正确答案】 D

【答案解析】[听力原文] U.S. President Barack Obama has said the time has come for a review on the U.S. immigration system. He made his case at a high school in Las Vegas, Nevada, a day after a group of senators outlined a framework for reform. The White House and senators conceive a path to citizenship for many of an estimated 11 million undocumented immigrants in the U.S. He noted that the current system was 'out of date and badly broken'. Mr. Obama's case for an immigration reform reflects a blueprint he rolled out in 2011, though that did not go far. Mr. Obama now backs the Senate plan including making illegal immigrants pay taxes and fines, and sending them to the back of the queue before they can become American citizens. His 2011 blueprint also focused on a path to permanent residency and eventual citizenship. After eight years, individuals would be allowed to become legal permanent residents and would eventually become citizens five years later, according to his 2011 blueprint. What can we know about the immigration reform? 本题考查与移民政策改革相关的细节信息。新闻中提到Mr. Obama now backs the Senate plan including making illegal immigrants pay taxes and fines, and sending them to the back of the queue before they can become American citizens. 由此可知，奥巴马倡导的此次改革计划包括让非法移民纳税和缴纳罚金，并给他们提供获得永久居住权和公民身份的路径，故此次改革旨在解决非法移民问题，故选D。

【正确答案】 C

【答案解析】[听力原文] According to Obama's 2011 blueprint, how long would it take for illegal immigrants to gain citizenship? 新闻在最后提到After eight years, individuals would be allowed to become legal permanent residents and would eventually become citizens five years later, according to his 2011 blueprint. 由此可见，根据奥巴马总统的2011蓝图，非法移民者要成为永久居民需要8年的时间，在此基础上再过5年即可成为美国公民，因而一共需要13年的时间，故选C。
