求英语高手指点，帮忙划分一下句子前半部分的成分，谢啦

Where previous athletes went over the bar while facing it,Fosbury developed a technique where he went over headfirst with his back to the bar.在他以前，运动员过杆时都脸朝下，福贝斯里却设计了一套头先过杆、脸朝上的新技术。

Answer 1

从句where引导的状语从句
Where/ previous athletes主语/ went 谓语/over the bar宾语 /while（they are) facing it 时间状语从句,
主句，Fosbury/主语 developed 谓语/a technique 宾语/where he went over head first/ with his back to the bar.where引导的同位语从句
在他以前，运动员过杆时都脸朝下，福贝斯里却设计了一套头先过杆、脸朝上的新技术。
