She was teaching (teach) very badly,while she was sitting (sit) at the back of the room and was watching (watch) her.這里sit我認為是用 was sitting,但答案是sat. why?

Miss. White usually teaches (teacher) very well,but she didn't teach (not teach) very well yesterday.She was teaching (teach) very badly, while she was sitting (sit)at the back of the room and was watching (watch) her students.后邊可能漏了students. while引導(dǎo)的句子不必前后用進行時.這里描述她昨天的情況,只是"坐在教室后邊監(jiān)視學(xué)生",還可以寫成:She was teaching very badly, while she sat at the back of the room watching her students.

was teaching和 was watching為并列的兩個句子，而 while部分為前面句子的補充部分

太亂，看不懂。she指的是the teacher， her指的是誰？
