is being 和are being
3个回答

is being 和 are being 都是被动语态的正在进行时态 .

is 和 are的使用取决与主语的人称数:一般情况下,第三人称单数就用 is ;you 及复数就用 are 了:

eg:

You/they are being told how to dance by the teacher at the moment (now).

She is being told how to dance by the teacher at the moment (now).举了同样的例子便是为了于对比区别.

下面的句子是正确的:I could dance very well when I was still young..

英语只要掌握基本的语法知识,多读就可以学的很不错的(个人意见)
