单选题
Chime Bank would have become the largest financial institution in the world ______ its acquisition of BBO International had been carried out. A. so B. then C. there D. if
【正确答案】
D
【答案解析】这道题考查的是连词，所以需要了解整句的意思，把握空格前后的上下文关系是最重要的。而如果换作运用相关的语法知识来解本题，也是可以秒杀的。因为前半句有“would havebecome”，后半句有“had been carried”，所以能推断出这句话表示过去情况的虚拟(If Shad过去分词，S would have过去分词)，即可得出是(D)。
