问题补充：

I would love to the party last night but I had to work extra hours to finish a report.

A. to go

B. going

C. to have gone

D. to be going

答案：

A. to go

B. going

(答案→)C. to have gone

D. to be going

解析：本题考查非谓语动词。would love或would like后要接动词的不定式形式，不能跟动词的-ing形式，排除B；would love to do sth. 意为“想去做某事”，指将来的动作；would love to have done sth．意为“本来打算去做某事，而由于某种原因没有做。”根据题意“昨晚我本打算去参加宴会的，但我不得不加班赶完一份报告。”可知答案为C项。
