题目解答
答案
解析
考查要点:本题主要考查学生对文章主旨的把握能力,需要根据段落内容准确判断其核心主题。
解题思路:
- 定位核心信息:文章围绕“加拿大交通系统”展开,重点描述其建立的必要性、建设难度、铁路成就及现状。
- 排除干扰项:需区分“历史”“不同交通方式”“进步”等与“现状”相关的概念,明确文章未涉及具体历史事件或技术发展。
- 锁定关键句:文章多次提到“运输系统的必要性”“建设困难”“铁路现状”等,直接指向交通现状的描述。
选项分析
A. the history of Canadian transportation(加拿大交通的历史)
- 错误原因:文章未详细叙述时间线或历史事件,仅提到“上个世纪修建铁路”和“1990年数据”,属于时间背景而非历史主线。
B. the different forms of transport in Canada(加拿大不同的交通方式)
- 错误原因:文章仅聚焦于铁路运输,未提及公路、航空等其他交通形式,无法涵盖“不同交通方式”。
C. the condition of transportation in Canada(加拿大交通的状况)
- 正确原因:文章全面描述了加拿大的交通现状,包括必要性(国土面积大)、挑战(地理因素)、成就(铁路长度)及现状(货运公司主导)。
D. the advancement of Canadian transportation(加拿大交通的进步)
- 错误原因:文中虽提到铁路成就,但未强调“技术进步”或“发展过程”,重点在现状而非进步性评价。
