单选题 Speaker A: I sent a package to Dallas two days ago and it still hasn"t arrived. My tracking number is 641-24.
Speaker B: Ok, Mr. Smith. ______ but our delivery person said that there was no such address.
【正确答案】 C
【答案解析】[解析] 本题考查询问信息的场景表达。说话人A向对方说自己寄送的包裹两天了还没有到，说话人B提到“但是我们的快递员说这个地址不存在”，由本句话的内容可以推测，正确答案应该是C“我们尝试过投递包裹”。A选项“别生气”，B选项“保持平静”，D选项“感谢询问”，均与题意不符。故选C。
