Question

求助，这个句子的从句到底是above which是主语还是逗号前的句子是主语

By nine o’clock，all the Olympic torch bearers had reached the top of Mount Qomolangma，above which appeared a rainbow soon.

Answer 1

从句部分的主语是 a rainbow, 这里用到了全部倒装。
A rainbow appeared above Mount Qomolangma.

追问

懂了，问一下介词＋关系代词可以做从句的主语吗？

Answer 2

从句的主语是the top of mount opmolangma，which的位置就是这个。全句的意思是，在将近九点的时候，奥林匹克的队员登上了珠穆朗玛峰，在那上面出现了彩虹。

Answer 3

• By nine o’clock，all the Olympic torch bearers had reached the top of Mount Qomolangma，above which appeared a rainbow soon.

  到9点钟,所有的奥运火炬手达到了珠穆朗玛峰,上面出现了一道彩虹。

Answer 4

绝对不是倒装句，主语一定不是rainbow。
