问题 At one time we had about eighty people here who did nothing but______into his family history.

选项 A、to research
B、researched
C、researching
D、research

答案D

解析本题考查but作介词后面跟动词不定式的用法。在这一结构中but为介词，后面可以跟带to的不定式，或跟不带to的不定式。一般情况下后面使用带to的不定式，但是如果在but前面的句子成分中出现了动词do及该动词的其他时态的相应形式，都需要使用不带to的不定式。本句中but前面出现了who did nothing，故选项D为正确答案。
