(2009江苏四市联考) 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

A. of whichB. on whichC. from which(答案→)D. above which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。
