21.______that the pilot couldn’t fly through it.( )

　　A.So severe was the storm

　　B.The storm so severe was

　　C.So the storm was severe

　　D.Such was the storm severe

　　21.A【解析】在so…that…结构中，若将so+形容词/副词置于句首，则其后的主句要用部分倒装。故C选项错误;B选项的正确形式应为“The storm was so severe”;D选项应为“It was such a severe storm”。故只有A选项正确。

　　22.The senior official was the person______.( )

　　A.whose honor the ball was given

　　B.whom the ball was given for him

　　C.for him the ball was given

　　D.in whose honor the ball was given

　　22.D【解析】句意：这场舞会为了纪念这位高级官员而举办。分析句子可知，the person为先行词，在后面的定语从句作honor的定语，所以关系代词为whose，排除B和C。in one’s honor指“为了庆祝或纪念某个人”，排除A。故D选项正确。
