SC 700-800 求解释

19. In the wake of several serious cases of mercury poisoning caused by tainted fish, the state

government ordered that all lakes and streams should be tested for mercury levels.

a。 all lakes and streams should be tested for mercury levels

b。 all lakes and streams should have their mercury levels tested

c。the mercury levels be tested for all lakes and streams

d 。the mercury levels of all lakes and streams should be tested

e。 the mercury levels of all lakes and streams be tested

答案是e但是我选的d，就是想问有没有大神知道为什么这里不能用should be而只能用be。解释是The non-underlined portion of the sentence contains the phrase "ordered that," which requires a clause containing the subjunctive mood. However, this choice uses "should be tested" instead of the subjunctive “be tested.”

关于这里虚拟语气的知识我了解甚少，有人愿意讲解一二吗？

像命令（order demand）坚持（insist）等词语打头的，后面用虚拟语气，我自己喜欢先用后面直接跟动词原形，should似乎在这里被认为是多余的（我记得高中似乎可以加上should）

一般虚拟语气就总结了7个，order算是第8个吧
