Question

we were wandering in the street when
we were wandering in the street when from behind ______,which made us scared.空里填的是came a frightened voice ,那为什么不用did a frightened voice come呢?不都是倒装么?

Answer 1

from behind 一类表位置关系的介词短语放在句子前面时一般用【全部倒装】语序
再如：
On the wall hangs a picture
In front of the house sat an old man
did a frightened voice come 是部分倒装,不符合习惯
