Lost of empty bottles were found under the old man'bed.He must have done nothing but_____
A drink
B to drink
C drinking
D drunk
我认为选B,因为but前不是动词,所以不定式加to.但是正确答案是A
▼优质解答
答案和解析
nothing but 后跟 to do 还是do, 要看主句的 动词,前后一致
I can do nothing but wait. (前面原形,后面原形)
I am going to do nothing but to wait. (前面不定,后面不定式)
根据这个可以回到题目那里看,它的谓语是must have done,在情态动词must后面必须是动词原形,所以选A啊.
望采纳哦
