A 我还没来得及跑过去他就挣扎着站起来了
构成过去完成时 .在我到之前他的动作已经发生了

B 我到之前就站起来了。

A before

A before 在..之前
翻译：--你为什么没有帮那个小男孩？
-- 噢，对不起，在我到达那之前，他已经挣扎着站起来了

A. before 主句是过去完成时，发生在从句一般过去时之前，故用before

选A before 在---之前，----后、才---
在我跑到之前，他就站起来了。

你为什么不帮助这个小男孩？噢，对不起，在我还没有到之前他就已经站起来了。选择A

选A吧 因为从句意上可以看出 你为什么不帮那个小男孩？对不起，我跑过去之前他已经绊倒了！里面是存在一个先后关系了，主要就是语境的把握！希望能够帮到你！

A

选A
A的意思是：在……之前
B的意思是：在……之后
C的意思是：直到……
D的意思是：自从……
根据句意思是：在我到之前，他已经摔倒了，所以才有了前面那句：你为什么不帮助这个小男孩？

选A 我还没来得及跑过去他就挣扎着站起来了
