独立主格

题目

独立主格
school being over,the students left the classroom and went home,为什么用being而不用 had being完成时态呢?因为后面用了went了啊.时态…….为什么?

答案

你的句子是独立主格,其中 school being over是伴随状态,可以改写成when school was over,其实非常简单.又如：
As Mike had fallen ill,I did the work instead of him.你就把从句部分改动一下,去掉as,主语保留,把had变成having.-----------Mike having fallen ill,I did the work instead of him.
你的句子也是如此,把was变成be,再把be换成being.
现在你会了吗?a good day to you.
