OG12-SC-133，关于require的固定用法

yunshishow

133 Last week local shrimpers held a news conference to take some credit for the resurgence of the rare Kemp's ridley turtle, saying that their compliance with laws requiring that turtle-excluder devices be on shrimp nets protect adult sea turtles.
(A)    requiring that turtle-excluder devices be on shrimp nets protect
(B)    requiring turtle-excluder devices on shrimp nets is protecting
(C)   that require turtle-excluder devices on shrimp nets protect
(D)    to require turtle-excluder devices on shrimp nets are protecting
(E)    to require turtle-excluder devices on shrimp nets is protecting
这道题答案选B。但是B中是require sth的结构，怎么看都不顺眼。不是只有require to do sth这种固定用法吗？

这里是require虚拟语气的用法 require that turtle-excluder devices be on shrimp nets, 但是用在这里要用这个虚拟句子的内容来补充说明laws，这就又涉及到另外一个语法点，即对法律内容进行说明的时候用V-ing形式，因此这里是省略that和be变短语来对laws进行说明的
