答案：
(答案→)A. Can you give me a hand?
B. How are you getting on with your work?
C. What can I do for you?
D. What a nice day!
解析：考查礼貌用语，Can you give me a hand?意思“你可以帮助我吗？”， How are you getting on with your work?意思“工作进展的怎么样？”，What can I do for you?意思“我能为你做些什么？”，What a nice day!意思“多好的一天啊！”，由后面的回答“当然，乐意效劳”，所以选A
