 题目是Senator Lasker has proposed legislation requiring that employers should retain all older workers indefinitely or show just cause for dismissal.

(A) that employers should retain all older workers

(B) that all older workers be retained by employers

(C) the retaining by employers of all older workers

(D) employers’ retention of all older workers

(E) employers to retain all older workers

A的SHOULD 为什么是多余的？

我理解是虚拟语气require/request/mandate/demand。。。 +that (should) do.

should 是可有可无而不是多余。请大家指点下。

真相是。。。。should必须省略。。。。
