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

答案选B，我没疑问。

但我做题的时候总觉得后边的动词时态有问题，为什么是用一般现在时？不应该和主句的held保持时态一致吗?
我看题目的时候就已经想到这个了，本来想借此排除几个错误选项，结果发现全都不用过去时。。。顿时傻了。

从句的时态和主句向来是独立的。给你句话就明白了，she said she is a teacher.

主句和从句时态向来都不是独立的吧。。。

有三种情况，主句用过去时或过去完成时，从句都用现在时:

1)当从句描述宏观事实存在的事情时
2)当从句描述的是政府规定的事情时
3)当从句描述的是科研成就，统计结果时

这里应该属于第二种。
