Question 2 is based on the news report you have just heard.

News Report One

    New York State plans to shut off the thundering waters of Niagara Falls—again. At least, the American side of the falls. This “once in a lifetime” event actually may take place twice in some folks’ lives. 

    The New York State parks system wants to turn off the falls on the American side sometime in the next two to three years to replace two 115-year-old stone bridges that allow（1）pedestrians, park vehicles and utilities access to Goat Island. The American side of the falls were shut off in 1969 to study the buildup of rock at the base of the falls. When that happened, people came from all over the world to see the falls turned off. 

    People are curious by nature. They want to see what’s underneath. （2）In fact, those who first came to have a look did see something. They found millions of coins on the bottom.

2. What did people find when Niagara Falls were shut off in 1969?

解析：D。该题目为细节题。问题为：1969年 尼亚加拉瀑布关闭时，人们有什么发现？出题点位置在报道尾端尾句。考点出自原文“They found millions of coins on the bottom”一句，他们发现瀑布底下有数百万枚硬币。选项D) Millions of coins on the bottom，其含义和形式与该内容完全一致。采用视听一致和选项关键词再现率原则，可以选出正确答案D。
