从别的帖子上找来的一个例子

(A) reduced the amount of phosphates that municipalitieshad been allowed to dump

(B) reduced the phosphate amount that municipalitieshad been dumping

(C) reduces the phosphate amountmunicipalities have been allowed to dump

(D) reducedthe amount of phosphates that municipalities are allowed to dump

(E) reduces the amount of phosphatesallowed for dumping by municipalities

DUKB24

quote:

"laws to require..." isn't a correct idiom if you're discussing the actual text of the laws themselves.


if you were discussing the ultimate purpose of those laws, then this could be idiomatic.




examples:
laws specifying long jail sentences for drunk drivers --> correct (___ing), since that's what the laws actually specify.


laws to specify long jail sentences for drunk drivers --> incorrect (that's not the ultimate purpose of the laws)


laws to discourage drunk driving --> correct (this IS actually the ultimate purpose of the laws)
