问题补充：

The exciting news he had been looking forward at last, so he did nothing but.

A. to came; cry

B. to coming; cry

C. to come; to cry

D. of come; to cry

答案：

(答案→)A. to came; cry

B. to coming; cry

C. to come; to cry

D. of come; to cry

解析：A考查句式。look forward to为定语修饰news，此句主语为news，谓语为came；故排除B，D；后空前面动词为do，but后面的词为原形动词。
