单选题 There is more land in Australia than the government knows ______.
A. what to do with B. how to do
C. to do with it D. to do it

【正确答案】 A
【答案解析】[解析] 该题旨在考查动词know和短语动词do with的用法。我们知道动词know后面既不能接动名词,也不能接不定式作宾语,所以C项和D项皆不是正确答案。但动词know后面可以接“疑问词+不定式”的结构,例如:Nobody knows how to operate the new machine. 没有人知道怎样操作这台新机器。He doesn't know what to say before the VIP. 他不知道在那位大人物面前该说些什么。do with意为“处理,对付(deal with)”,例如:what did you do with yourself last Sunday?上个星期天你是怎么度过的?The children didn't know what to do with themselves for joy. 孩子们高兴得无法控制自己。由此可见,A项正确而B项错误。
