形式为should （not）do…的宾语从句表示虚拟语气吗?

要看前面的部分是什么.
若：i have told you that you shouldn't do this.句中的should仅仅表示应该的含义.为情态动词的考查范围.
如果与虚拟语气有关,比如：
it is high time that you should do your own work.
以上两句均为should做宾语从句的部分,但是很明显用法不同.
关于should,一般就考察做情态动词表语气如：you should have done this.表责备语气.或是考察关于虚拟语气：he requires that you (should) finish it.
