【题目】
According to the Paragraphs 1 and 2, many young Americans cast doubts on___.
[A] the justification of the news-filtering practice.
[B] people's preference for social media platforms.
[C] the administration's ability to handle information.
[D] social media was a reliable source of news.
【解析】根据题目定位到第1段和第2段，双段推理优先考虑双段主旨。*一段中心句为最后一句话：Millennials prefer news from the White House to be filtered through other sources，not a president's social media platform。“千禧一代喜欢来自白宫的消息通过其他方式得以透露，而不是总统的社交媒体平台”，说明他们不太信任社交媒体。第2段中心为第二句转折之后，说明人们对于社交媒体的不信任上升。故双段中心都和他们不信任社交媒体相关。结合以上信息，得出社交媒体信息不可靠，选择D。选项[A]中的justification，文中并未提及，属于无中生有；选项[B]中的preference在前两段也未提及；选项[C]中的ability to handle information同样属于无中生有。

【题目】
The phrase "beef up"(line 2, Para.2) is closest in meaning to___.
[A] sharpen
[B] define
[C] boast
[D] share
【解析】根据题目定位到第2段第2句：Yet as distrust has risen toward all media，people may be starting to beef up their media literacy skills。因为逗号前提到“人们对于所有媒体的不信任增加”，根据句子的情感色彩可以推知人们应该开始增强其媒体素养的技能，故选A。选项[B]和[D]没有办法表达增强、提升的意思，故排除；选项[C]表达的是负向情感，和文章的情感色彩相反，也排除。
