问题 There is a real possibility that these animals could be frightened, ________a sudden loud noise.

选项 A、being there
B、should there be
C、there was
D、there have been

答案 B

解析 如果突然有很大的噪音,这些动物很可能会受到惊吓。虚拟语气题。从句意判断,该句讲的是一种假设的情况,使用与将来事实相反的虚拟语气。当条件状语从句中含有should、were或had时,可以将if省略,should、were或had提前,构成部分倒装,可以还原为if there should be。故B选项为正确答案。
