问题 The experiment requires more money than______.
选项 A、have been put in
B、being put in
C、has been put in
D、to be put in
答案C
解析 省略用法。本句中than引导比较状语从句，从句中的主语被省略，另外，“投入了的经费”要使用完成式，money为不可数名词，故本题has been put in为正确答案。类似用法的句子如：There were more people than was expected．/We were kept waiting longer than was absolutely necessary．
