The climate of the west coast is the most moderate in Canada. Summers are cool and fairly dry and winters are mild, cloudy and wet. Even in mid-winter, average temperatures arc usually above freezing.
    The central plain from the Rocky Mountains to Great Lakes is characterized by cold winters, short but hot summers,  and light snow and rain. The large water-surfaces of Central and Eastern Canada produce considerable modification  in the climate. Southern Ontario, and Quebec experience cold, damp winters and hot, humid summers.
    Most of Atlantic Canada has a humid climate owing to its maritime character. Nevertheless, it experiences weather  systems arriving front the dry continental interior as well as from the sea. The combined influence of these systems creates some of the most variable day-to-day weather conditions to be encountered anywhere in Canada.
    The north-central part of Canada is usually snow-covered for more than half of the year, with a frost-free period of barely two months. Rain is relatively light. Further north, on the islands along the Arctic coast and round Hudson Bay, the land is always frozen. Average temperatures stay above freezing for only a few weeks of the year. The Arctic Islands and the northern border of the mainland do not have a summer season of the kind known in Southern Canada.

选项 A、The Arctic coast.
B、The west coast.
C、The east coast.
D、The central plain

答案 C

解析 事实细节题。文章中提到加拿大的中部湖区和东部地区气候变化相当大(produce considerable modification in the climate),所以应选C。A文中提到北冰洋沿岸最冷(frozen);B文章中提到西海岸地区的气候最温和(the most moderate);D文中提到中部平原地区的气候特点是冬冷夏热,雨雪较少(cold winters,short but hot summers,and light snow and rain)。这道题问的是哪个地区气候最多变,这二项都答非
