We are sure this was just due to carelessness in quality control,and that you will send another shipment of shirts promptly to replace this faulty one.
【正确答案】 A
【答案解析】解析:A)一C)一B)。解答本题的关键在于正确把握句子结构,due to引导的短语所充当的成分,以及shipment和promptly的意思。从句子结构上来看,We are sure后面接两个由and连接的宾语从句,其中第一个从句省略了that,正确把握这一结构是正确翻译的关键;due to引导的短语在从句中充当表语,而不是独立的原因状语;shipment的意思是“装运,运送”;promptly的意思是“立即,马上”。
