—What is the man, do you know?
—I don’t know exactly. But I think he can be but a teacher.
A. anybody
B. something
C. anything
D. everybody

A. anybodyB. something(答案→)C. anythingD. everybody解析：考查不定代词。句意：。--你知道，那个男士是干什么工作的吗？---我的确不知道。但我认为绝不是一个老师。anything but =not, never表示绝不，根本不，除此之外别的都是。后面可以接名词，代词，形容词，分词及不带to的不定式。He is anything but a teacher. 他决不是一个老师。（后接名词）I'll do anything but that. 我决不干那件事。（后接代词）；nothing but=only表示“只是，只有，只不过，除……而外，什么也没有”。用法与anything but一样。故C正确。
