单选题 I expected a more enthusiastic welcome, especially ______ it is the first time I have come here.
A. providing C. comparing B. supposing D. considering

【正确答案】 D

【答案解析】[分析] considering“考虑到”，是引导原因状语从句的从属连词，若后接that引导的从句，则considering是介词，如：Considering(that)they are just beginners，they are doing quite a good job．A项providing(that)“只要”；B项supposing that“假定”，不符合题意，C项comparing不是连词，故均可排除。只有D是正确答案。
