【答案解析】[听力原文]17-20
Thomas Jefferson was inaugurated on March 4, 1801. He was the first President to take the oath of office in the nation's permanent capital, Washington D. C. Although Washington was a new city it was already familiar to President Jefferson. In fact, Jefferson had helped plan the capital's streets and public buildings. Besides being a city planner and architect, the new President was a writer, a scientist, and the inventor of several gadgets and tools.
After his inauguration, Jefferson moved into the Presidential Palace. The Palace was more than a home; it contained offices for the president and some of his staff and advisors. It also included dining and reception room, where the President could entertain congressmen. However, President Jefferson did not give many formal parties. This was partly because there was no First Lady; Jefferson's wife had died in 1782. But it was also because Jefferson liked to live in a simple fashion. Once, he showed up for an important meeting wearing old clothes and down-at-the-heels slippers! Neither Washington nor Adams would ever have dressed so casually.
Jefferson was different from the first two Presidents in other ways, too. He disagreed with them about how the country should be run, and about what part a President should play in running it.
17．Which one is implied about Washington D．C．?
推理判断题。短文第一段中介绍了杰斐逊于1804年3月4日宣誓就职，他是第一位在首都华盛顿宣誓就职的总统。华盛顿尽管是个新城市，但杰斐逊对它并不陌生。因为他亲自参与了该市的建筑与规划。根据我们对短文以及美国文化的了解，我们知道杰斐逊是美国的第三任总统，文中提到他是第一位在首都华盛顿宣誓就职的总统，那就意味着在他之前的两任不是在华盛顿就职的，所以可以推断出华盛顿不是美国的第一个首都。
