(2013·高考浙江卷)The children， had played the whole day long，were worn out.
A. all of what
B. all of which
C. all of them
D. all of whom

A. all of whatB. all of whichC. all of themD. all of whom解析：选D。题干的意思是：“孩子们玩了一整天，都累坏了。”分析句子结构可知， had played the whole day long是非限制性定语从句，先行词children指人，故排除A、B、C三项。所以正确答案为D项。
