Question

Ottawa is the capital of Canada. It is the second largest city in Ontario and the fourth largest city in the country.

The Centre Block is the main building on Parliament Hill (國會山). It is also the location of several ceremonial spaces, such as the Hall of Honor and the Memorial Chamber. 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.

Downtown Ottawa is the commercial and economic centre of the city. 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. The downtown also contains a number of apartments, hotels, and the older single family homes and townhouses along its edges.

The National Gallery of Canada is one of Canada，s premier art galleries. 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.

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.

解析試題分析：文章描寫了加拿大渥太華著名的幾處地方，并分別對這幾處地方進行詳細的說明。
【小題1】細節推斷題。從第二段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，現如今的中央街區是重新翻修的，以前的那一座在1916的大火中被毀壞了。所以iteration的意思相當于copy，復制品。故選C.
【小題2】細節題。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.可知在渥太華的市中心都是辦公大樓，而且主要是高科技行業的辦公大樓，故選B，而不能選C、D，因為文章中講到市中心最主要的是辦公大樓。
【小題3】細節題。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，主要收藏的是各種各樣的畫以及雕像、照片。它主要是收藏加拿大人的藝術作品，同時也收藏美國人和歐洲人的作品，故選C。
【小題4】判斷題。A答案中它是最古老的的現在仍在使用的水溝系統，并不是最老的水溝系統，排除。C,文中講到絕大部分沒有改變原貌，并非全部沒有改變，排除。D，文章講的是五月中旬到十月中旬，故排除D.從At the very beginning，the purpose of the Rideau Canal was military可知，最初的目的是軍事目的。故選B.
