问题补充：
she was fully conscious all the time and knew what was going on.她一直都很清醒,知道是怎么回事.knew what was going on.what = that which 缩合关系代词引导从句作宾语.这个从句我不太清楚句子成分~which was going on
答案：
1、划分句子成分有助于理解你的问题：
【She主语】【 was fully conscious谓语 】【all the time 时间状语】and 【knew 并列谓语】【what was going on.宾语从句】
2、替换理what= all/everything/something that
She was fully conscious all the time and knew【all/everything （that was going on定语从句).】
祝你开心如意!
