(单选题)

Though the teacher asked a very difficult question, Tom ______ up with a very good answer immediately.

A.put

B.kept

C.came

D.caught

参考答案：C

参考解析：

考查动词短语辨析。句意：虽然老师问了一个很难的问题，但Tom立即就想出了一个很好的答案。put up with意为“容忍，忍受”；keep up with意为“与……接触”；come up with意为“提出，想出”；catch up with意为“追上，赶上”；根据句意，应是Tom回答老师问题，所以是“想出”答案，故选C。
