________didhe________onhiswaytothelecture？Helostthekeytohisbikeonhis

________did he________on his way to the lecture？He lost the key to his bike on his way to the lecture．A.What，doB.Where，goC.What，loseD.Where，lose

C解析分析：如果是对整个谓语部分lost the key to his bike提问，似乎是What did he do on his way to the lecture？但What did he do是问主语有意识的动作，此处lost the key绝对不是主语有意识的动作，正确的提问应该是What happened to him on his way to the lecture？B项和所给的on his way to the lecture是矛盾的。D项的lose缺少了宾语。

和我的回答一样，看来我也对了
