单选题 Your order of printer paper has already been shipped from our warehouse______ will most likely arrive late due to poor weather conditions.

A、 but
B、 until
C、 even
D、 since

【正确答案】 A

【答案解析】解析：此处需要填入连接两个拥有共同主语Your order的谓语has already been shipped和will most likely arrive的并列连词，且根据上下文语义，此处句意应为“已发货但会稍迟送达”，故并列连词(A)but(但是)为正确答案。but用于连接语义相反的分句。状语从句连接词或介词(B)和(D)以及程度副词(C)都不能连接两个谓语。
