题目：
It is said in Australia there is more land than the government knows ________.
A．it what to do with
B．what to do it with
C．what to do with it
D．to do what with it
答案：
答案：C
“疑问词＋不定式”作动词“knows”的宾语，而to do with sth意为“处置、对付”是固定搭配。“it”是“with”的宾语指“the land”。“what to do with it”当于宾语从句“what the government should do with it”。
