单项选择题
Speaker A: Excuse me, do you need a hand Speaker B: ______
A．Oh, yes, please. I haven't used one like this before.
B．No, thank you. I don't need another hand.
C．Sorry, do you know how to do this exercise
D．of course. I need a hand.
答案
参考答案：A
解析：A方主动向B方提出是否需要帮忙。B方需根据实际情况接受或谢绝别人的好意。A项和B项前半部分都是恰当的回答，但B项的后半部分显示B方误解了A方的话。C项后半部分恰当，但前半部分用“Sorry'’错误，D项前半部分用Of course，显得不太礼貌。
