The Rideau Canal is the oldest continuously operated canal system in North America. At the very beginning，the purpose of the Rideau Canal was military, as it was intended to provide a secure supply and communication route between Montreal and the British naval base in Kingston.

(答案→)B 解析：文章描写了加拿大渥太华著名的几处地方，并分别对这几处地方进行详细的说明。【小题1】细节推断题。从第二段The present Centre Block is the second iteration of the building，after the first was destroyed by fire in 1916，and it is one of the most recognizable buildings in Canada.可知，现如今的中央街区是重新翻修的，以前的那一座在1916的大火中被毁坏了。所以iteration的意思相当于copy，复制品。故选B【小题2】细节题。Most of the buildings are office towers. While most of Ottawa’s high tech industry is based elsewhere, it has a significant presence in the downtown core.可知在渥太华的市中心都是办公大楼，而且主要是高科技行业的办公大楼，故选C，而不能选B、D，因为文章中讲到市中心最主要的是办公大楼。【小题3】细节题。The Gallery has a large and varied collection of paintings, drawings, sculpture and photographs. Although its focus is on Canadian art, it also holds works by some noted American and European artists.可知，主要收藏的是各种各样的画以及雕像、照片。它主要是收藏加拿大人的艺术作品，同时也收藏美国人和欧洲人的作品，故选D。【小题4】判断题。B答案中它是最古老的的现在仍在使用的水沟系统，并不是最老的水沟系统，排除。C,文中讲到绝大部分没有改变原貌，并非全部没有改变，排除。D，文章讲的是五月中旬到十月中旬，故排除D.从At the very beginning，the purpose of the Rideau Canal was military可知，最初的目的是军事目的。故选A.

就是这个解释
