(单选题)

I was lucky to be given an opportunity ______ I could put what I had learned to use.

A.when

B.what

C.where

D.which

参考答案：C

参考解析：

考查关系副词where的用法。句意：我很幸运地得到了一个机会，可以把我学到的东西用上。根据句意可知，此处I could put what I had learned to use为定语从句，限定修饰先行词opportunity，定语从句中主语为I，谓语动词为could put to use，what I had learned充当put的宾语从句，因此定语从句不缺少主宾表，因此应填入关系副词，opportunity为抽象地点，故填入关系副词where。故选C。
