Question

【题目】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

Answer 1

【答案】D

【解析】句意：孩子们因为玩了一整天，都已经精疲力竭了。本题考查定语从句的用法。先行词为the children，将先行词代人定语从句后为：All of the children had played the whole day long. 由此可见，先行词在定语从句中作of的宾语，且先行词表示“人”，故只能用all of whom。
