before doing sth
我看见有一个就是说 before having to make a turn.能介绍一下为什么这样用么?

efore doing sth 做某事之前（完全正确的用法）
before having to make a turn 在必须转弯之前
例句与用法
1.We must have a plan before doing any work.

before doing sth before doing sth还是do sth before doing sth 和 before you do sth,为什么? before sb doing还是do sth 求 before doing sth的用法? help,open的过去分词是什么?是before sb do sth.还是before sb doing sth... before什么时候加doing sth./sb.do sth.什么时候before后加一般过去时的句子或过去完成时的句 before doing与before do approach to sth /doing sth after doing sth 还是 after doing sth? 翻译 prefer doing sth to doing sth perfer doing sth to doing sth
