Question 16 A、The problems caused by the Revolutionary War. B、How some people became rich in the late 1700s. C、The importance of establishing a tax system in the Constitution. D、Motives for creating the United States Constitution. 解题思路: ① 两项提及 Constitution。 ② 四项均为名词(性)短语,相互之间的关联度不高。 结论: 由于本题为本篇短文的第一题,因此很可能考查听力短文的主题 详解: 讲话者在开头处就介绍自己将要谈论的内容是“对于美国编写1787年宪法的初衷目前存在的两种观点”,D项中的 motives for creating 是原文中 the motivation for writing 的同义转述,the United States Constitution 为关鍵词复现。故选D。
