【正确答案】 C

【答案解析】[解析] 运动会由于暴雨而推迟举行。句中postpone：推迟。put up：举起，如：Put up your hands!举起手来!put away：把…收起，放好，如：The boy put the food away in the cupboard after he finished his dinner．小男孩吃完晚饭后把食品在橱里放好。put off：推迟，如：Don't put off until tomorrow what can be done today．今日可做的事不要拖到明天。put on：举行，假装，上演，如：put on a play上演一出戏剧。只有put off意思上和postpone最接近。
