Answer 1

61．was covered．考查谓语动词．主语the city 和谓语动词cover之间是被动关系，根据When Polly left home that morning可知cover用一般过去时态，所以用was covered．
62．foggy．考查派生词．修饰名词 day用形容词foggy，表示"一个大雾天"．
63．to run．考查固定句式．too…to表示"太而不能"，本句句义是雾太大了，汽车不能跑了．
64．arriving/arrival．考查非谓语动词或派生词．介词on用名词或动名词做宾语，表示"一到…就…"．
65．who．考查关系词．定语从句would come along to help her 的先行词是someone，缺少主语，所以关系用who．
66．her．考查代词．根据上文可知本句表示"让这个女孩吃惊的是"，所以用her．
67．finally．考查副词．修饰动词短语  accepted the offer用副词finally．
68．for．考查固定短语．watch out for表示"当心"．
69．later．考查单词变形．About half an hour later表示"半个小时以后"，late表示"迟到"．
70．losing．考查非谓语动词．lose做定语，修饰more people，二者之间是主动关系，所以用losing．
