Question

请问Never before_______see such a terrible car accident on the road!
A i have B have i C i did D did i 为什么选第四个

Answer 1

因为否定词放句首了，所以要倒装，将助动词提前。如果不倒装的话，原句应该是:I never saw such a terrible car accident on the road before.

Answer 2

选 D 这里考察的是现在完成时态的倒装句，状语提前了，句子应该用部分倒装结构

Answer 3

倒装句，never before+助动词+主语

Answer 4

就是引文不喜欢的意思吧！
