一Would you be so kind as to take this heavy box upstairs for me?

一

A. It’s my pleasure．

B. Help yourself．

C. Sure，with pleasure．

D. Take your time．

答案：

A. It’s my pleasure．

B. Help yourself．

(答案→)C. Sure，with pleasure．

D. Take your time．

解析：考查交际用语。It’s my pleasure，不客气，用于回答别人的感谢；Help yourself随便吃，随便用；Sure，with pleasure当然，乐意效劳，用于表示愿意提供帮助，答应别人的请求；Take your time别着急，慢慢来。句意：你能帮我把这个沉箱子搬到楼上吗？当然，乐意效劳。所以选C。
