单选题 At a party.
Adam: This is a great apartment.
Tammy: I think so, too.______?
Adam: No, I'm Adam. I came with Carl. I don't really know anyone here. Carl's told me about most of his friends, but I can't match the names with the faces.

【正确答案】 A
【答案解析】[注释] 聚会上两个互不相识的人Adam和Tammy在谈话,从Adam的回答看, A. Excuseme,but do I know you?符合对话语境,意思是“请问我们以前见过吗?” B.Excuseme,could I know you?与Adam的回答不一致;C,D显得唐突。
