单选题 They always lay in a large ______ of tinned food in winter in case they are snowed up.
A. provision B. supply C. proportion D. storage

【正确答案】 D

【答案解析】[解析] lay in a large storage of“大量贮藏”，符合题意。make provision for“为……做准备(做安排)”；furnish supply to“为……提供”或have a good supply of“有大量的”；a large proportion of“大部分”，用在句中不合适。
