看DUKB24 的千行excel上有下面的解释，没看懂


Ron对这题的解释：
"require" can also be used simply with a direct object, as in
i require perfection.
this device requires four AA batteries.
these are perfectly good sentences.
(d) and (e)
"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)

为什么laws to specify long jail sentences for drunk drivers --> incorrect (that's not the ultimate purpose of the laws)
没有表达出the ultimate purpose of the laws
而laws to discourage drunk driving --> correct (this IS actually the ultimate purpose of the laws) 表达出了呢？

你建立醉酒驾驶的目的不是去规定人们要去做牢，而是去抑制人们减少醉酒驾驶（这时用to）
醉酒驾驶规定喝酒驾驶的要无期徒刑（这时是规章制度的内容，所以用ing）
