英语两个介词连用的现象的语法解释

Question

I remember refying my parents when I grew my hair long. It was so long it was down below my shoulders.出自大学英语教材nhce.句中出现 down below连用,请问语法解释?

Answer 1

语法解释？没什么可解释的。为了满足准确表达句意的需要。少一个词就表达的不充分。
这句话是，我的头发垂下来一直到肩膀下面。down below表示 下来 并且 一直到。。。下面 的意思。

两个介词是可以连用的,在语法中叫做"二重介词"比如:
He jumped from behind the tree.
He waited there until after 8:00.

Answer 2

楼主说的这个不是两个介词联用，这里的down不是介词，是形容词而已。
两个介词联用的情况确实有，比如I watch the children playing football from within the room.

Answer 3

在我肩膀下面
down补充说明below

Answer 4

it was down
it was below my shoulders
有从句啊
