Whatdoyouthinkofthereason_______hementionedatthemeeting_______winning

What do you think of the reason _______ he mentioned at the meeting _______ winning this competition?A.why; whyB.that; ofC.which; whyD.\; for

D解析试题分析：通过分析句子结构，可知这个句子中包含一个定语从句，且关系词在定语从句中作宾语，先行词指物，故用that或which，也可省略。第二个空，表示“为了赢得比赛”，故用介词for。 考点：定语从句和介词的考查 点评：如果先行词是表示时间或地点的名词，不能就一律断定要用关系副词when或where，务必要看引导词在从句中作什么成分，如果作状语，用关系副词，如做主语或宾语要用关系代词。同理，当reason做先行词时，也需注意其引导词在从句中作什么成分，不能断定一概用why来引导。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。（定语从句中缺状语，表示原因，故用关系副词why）The reason that he explained for his being late was that he had missed the early bus.他所解释的迟到的原因是他误了头班汽车。（explain是及物动词，that在从句中作其宾语）
