試題分析：通過分析句子結構，可知這個句子中包含一個定語從句，且關系詞在定語從句中作賓語，先行詞指物，故用that或which，也可省略。第二個空，表示“為了贏得比賽”，故用介詞for。
點評：如果先行詞是表示時間或地點的名詞，不能就一律斷定要用關系副詞when或where，務必要看引導詞在從句中作什么成分，如果作狀語，用關系副詞，如做主語或賓語要用關系代詞。同理，當reason做先行詞時，也需注意其引導詞在從句中作什么成分，不能斷定一概用why來引導。如：The reason why I was absent yesterday was that I was ill.    我昨天缺席的原因是我生病了。（定語從句中缺狀語，表示原因，故用關系副詞why）The reason that he explained for his being late was that he had missed the early bus.他所解釋的遲到的原因是他誤了頭班汽車。（explain是及物動詞，that在從句中作其賓語）
