178. (31376-!-item-!-188;#058&005785)
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

这题选B  如果C 的protect改成protects的话 是不是C就没问题了？？？？做LAW的定语为什么要用requiring 不用THAT呢~~

prep笔记上又说，法律的内容用ing形式，然后根据require的用法，（或者你直接比AB，也明显B读起来更通顺，更接近正常人说话）B>A

思兼

这题。。。。。应该是因为require的用法问题吧。。。。

关于require的用法正确的形式有：require sb. to do sth.  ;    require  of sb. that  ;  require that ;   none + required of sb. to do sth.

D、E无问题所以不说了。。。。

而按照LZ所说的，如果要C正确的话，应该要把protect 改成 to protect 吧。。。。而且，为什么要改protects 呢。。。第三人称单数？？

至于A的话，错的地方应该是be on吧。。。。wordy而且awkward 了。。。。。

对于定语从句和现在分词修饰的区别，跟楼上所说的一样~~~~~

因为that定语从句表示的是一次性动作，而ving表示的是重复性动作，而法律颁布之后是在长时间内有效的，所以用ving。
