单选题 There is a real possibility that these animals could be frightened, _____ sudden loud noise.无

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

【正确答案】 B

【答案解析】句意：万一突然出现了噪音，这些动物就有可能受到惊吓。本题是一个省略了if的虚拟语气句，并且是与将来相反，从句可以使用： should+动词原形；原句为： If there should be a sudden loud noise, these animals could be frightened.
