谓语动词的形式为“is / are / am + being+过去分词”。如果去掉being, 就成为一般现在时被动语态或系表结构。试比较下列句子: Look! The children are being taken care of by their aunt.

瞧! 孩子们现在正由姑母照看着(指现在的情况) Children are taken good care of at school. 孩子们在学校被照看得很好。(指通常的情况)

The report is being written by one of the best students. 报告正在由一个最好的学生写着。

The report is well written. 报告写得很好。(系表结构)

The house is being painted. 房子正在被粉刷。
