问题补充：

—I’m sorry. That wasn’t of much help.

—Oh, . As a matter of fact, it was most helpful.

A. sure it was

B. it doesn’t matter

C. of course not

D. thanks anyway

答案：

(答案→)A. sure it was

B. it doesn’t matter

C. of course not

D. thanks anyway

解析：考查交际用语：句意：--对不起，那没什么帮助。---哦，那当然是（有帮助的）。事实上，它是最有帮助的。” B. it doesn’t matter没关系，D. thanks anyway仍然感谢，这两项明显不对，也不能选C，因为of course not的意思是“当然没帮助”，就与后半句的意思相反了。选A。
