I’m glad to see that you a lot of progress since I you last.

A. will make; have met

B. have been making; met

C. had made; met

D. have made; meeting

答案：

A. will make; have met

(答案→)B. have been making; met

C. had made; met

D. have made; meeting

解析：因为是“上次见你”，所以since从句的谓语动词用一般过去时，排除A和D；又表示从上次见你以来一直到现在并且现在依然在不断取得进步，所以用现在完成进行时。
