request等命令、建议动词后,从句用虚拟语气（should）do.可以用could,would,might+do吗?

不能 只用should加v原 should可省略 insist坚持要求“引述部分含insist、suggest、demand引导的虚拟宾语从句，引语的主从句时态都不变。”能给我举个例子吗？He said, “We insisted that she start immediately. She said, “He demanded that the girl leave at once.”变成间接引语就是"She said that he demanded that the girl leave at once."？嗯
