the child has made so much noise that he should not have been allowed to attend the concert.

问题描述:

the child has made so much noise that he should not have been allowed to attend the concert.
如何翻译,是什么时态,为什么allow是过去时.

这个孩子制造出这么大的噪音,他就不应该被允许参加这个音乐会
这个是虚拟语气,对他就不应该参加这个音乐这个事实进行虚拟,其实他已经参加了
引处用should来表示虚拟语气时,把一般现在时变为现在完成时,孩子是被允许,所以去过去分词形式你好,请问在句子“he should not have been allowed to attend the concert."中怎么又been和 allowed两个过去分词?这里面包括现在完成时,还有被动语态,所以要用have been allowed
