单选题 Speaker A: Hi. Excuse me, ...um ... do you need any help?Speaker B: ______

A、 Yes, but are you sure you can help me?
B、 Oh, yes. Do you have tennis shoes?
C、 Well, I'd like one chicken burger and a cup of coke, please.
D、 Oh, yes, I do. I've been walking around in circles. I can't seem to find the train station.

【正确答案】 D

【答案解析】A方主动向B方提供帮助，B方需作出接受或谢绝对方好意的答复。B和C项通常是对“Can I help you?”作出的答复，但显然不符合这一对话场合的要求。A项前半部分对，后半部分提出需要什么帮助，这不符合这一对话的逻辑关系。D项是在这种情景下正确的回答。
