Question

这里的should have been done是否为虚拟语气？谢谢

全句为：Without elaborating, she admitted that medical care for the terminally-ill had declined since the law came into effect. She said more should have been done legally to protect people who wanted to die natural deaths.
是否表示“应该已经被做了而没有被做“，谢谢🙏

Answer 1

She said more should had been done legally to protect people who wanted to die naturally.
先看这句话的意思：
她说，要采取更多的法律措施来保护那些希望自然siwang的人。
more should had been done.是含有情态动词的希望去做而没有做的愿望。可以看做是虚拟语气。

Answer 2

对的，Should have been done 是一个典型昀虚拟语气说法，因为这件事仍未完成。

Answer 3

对，这里表示应该被做，而没有做，主语是承受动作的。

情态动词should加动词的完成式，表示某事应该做，却没有做的意思，这里用了被动语态，主语是动作的承受者。这里的should可以用ought to来代换。
希望我能帮助你解疑释惑。
