Question

英语高手帮忙啊，这个选择题选什么？为什么

These animals would be frightened_____a sudden loud noise.
A.being there B.should there be C.there was D.there having been

Answer 1

1. 答案：B.

2. 翻译：如果有一场突如其来的喧闹声的话，这些动物就会被吓到。

3. 解释：
1）此题考查if引导的条件状语从句的虚拟语气语法。
2）当对将来的动作进行虚拟的话，则从句谓语动词可以由“should + 动词原形”构成，且可以把should提前至从句句首，并同时省略if.
3) 即: should there be a sudden loud noise
= if there should be a sudden loud noise

Answer 2

B 这是以个虚拟语气的句子，其实就是If there should be a sudden loud noise, these animals would be frighteded. should 可提前，省略if
