I’ve made it a rule ( )up late at night.
A.to stay
B.to staying
C.to be staying
D.for staying
A.to stay
B.to staying
C.to be staying
D.for staying
这道题选a
这实际上是it作形式主语的用法。
it a rule ( )up late at night
可改写为 it is a rule to stay up late at night
或者to stay up late at night it is a rule
换成这样的方式来看，这个题目就很容易理解了。
