Question

1.         By nine o'clock, all the Olympic torch bearers had reached the top of Mount Qomolangma, ___________ appeared a rare rainbow soon.

A. of which    B. on which   C. from which  D. above which

Answer 1

D

解析:

对于非限制性定语从句的题，我们可以将它拆为两句，找到两句的共同点（即先行词）然后再用关系代词连接。此题拆分后，逗号前为第一句，后面为第二句。原句应该是这样的：A rare rainbow soon appeared __________.这里显然应该填上“above Mount Qomolangma”。我们可以将它改写为above which并用来连接这两个句子，这样，这一道题依旧迎刃而解了。
