Question

Although the old man was ______ death, he still fought with the disease bravely. 　

A．at the end of	B．on the top of
C．at the edge of	D．on condition that

Answer 1

C

解析试题分析：句意:尽管那位老人身处死亡的边缘,却仍然在勇敢地同疾病斗争。at the edge of“在……的边缘”,符合句意。at the end of“在……最后”;on the top of“在……顶端”;on condition that“在……条件下”,后接从句。
所以选C。
