单选题
This notice is to provide information about ______.
【正确答案】
C
【答案解析】[解析] 本题询问这则通知提供了哪些信息。根据第一段第一、三句话可知这篇文章是关于申请参观白宫需要注意的问题。C项中的application for a tour与文中的requesting a tour同义，可判断C项为正确答案。
虽然第一段提到了A项中的scheduling( 排)一词，但根据下文的内容，文章说的并不是旅行团的路线安排。而B项的security system(安全体系)在文中没有提及。D项的a tour group leader(旅行团领队)只是在倒数第二段和第三段提到，不能概括全篇通知的内容。
单选题
The White House is open to the public ______.
【正确答案】
B
【答案解析】[解析] 题目中的open to the public意为“对公众开放(时间)”，故定位到第三个分点。该分点谈到，参观时间为周二到周六上午7:30至11:30，换句话说，一周开放五天。因此选B项。
工作日一般为周一至周五，而周六不属于工作日，因此可以排除A项。weekend一般指周六和周日，但是周日显然不能参观白宫，而周二至周五的工作日时间也可以参观，因此可排除D项。C项意为“每隔一天”，而原文中的Tuesday through Saturday表明时间是连续的，因此不选。
单选题
Application for a group tour of the White House must be submitted ______.
【正确答案】
B
【答案解析】[解析] 根据题目中的must be submitted定位第二个分点。该分点清楚说明，申请必须至少提前一个月(a minimum of one month"s advance notice)交，即至少30天。所以B项是正确的。
文中没有谈到申请必须在当天(exactly on the date...)提交，不难排除A项。C项是参观白宫的时间，D项是公布是否批准参观的时间，两者都不是提交申请的时间。
单选题
After your tour request has been confirmed, ______.
【正确答案】
A
【答案解析】[解析] 根据题目中的tour request has been confirmed定位第二个分点。该分点最后一句谈到，所有参观活动，包括已经确认批准的(have been confirmed)，都可能由于安全问题而被取消(cancellation)。A项中的may be cancelled对应文中的are subject to cancellation，是正确答案。
B项中的are still allowed to change，C项surely visit和D项的start...immediately都没有在文章中提及。文章只谈到了即便被批准的游览团也有可能被取消，只有A项符合。
