问题补充：

Jerry was very excited to see the playground she used to play football with lots of snow.

A. where; covered

B. which; covered

C. /; covering

D. where; covering

答案：

(答案→)A. where; covered

B. which; covered

C. /; covering

D. where; covering

解析：第一空考查定语从句，先行词为the playground，从句中缺少地点状语，故用关系副词where，第二空考查 see sth done，句意：翟瑞非常的兴奋看到她过去常常打篮球的操场被覆盖上了许多雪。所以选A。
