Question

______, I went to school instead of her yesterday. A.she is ill B.Her being ill C.She being ill

D.Being ill
为什么不选A 要选B？详细、准确的解释一下

Answer 1

选A的话，逗号前是一个句子，那么逗号后要有一个连词and，这样两个句子才能连接起来。
B.中being ill 是一个逻辑上系表关系的现在分词短语，又用形容词性物主代词her 作其定语；整个的Her being ill是一个独立主格结构，用作原因状语，代替了一个原因状语从句。

这句话什么意思？能讲的再清楚点吗？

追答

写一个原因状语从句：Because she was ill, I went to school instead of her yesterday.
这里Because she was ill = Her being ill

追问

为什么这里是Her而不是She？being ill是什么意思？

追答

Her是“她的”，可以做定语；而She是“她”，不能作定语。being ill是“生病”

追问

Her being ill代替了什么原因状语从句？

追答

Because she was ill “因为她当时病了”，这就是一个原因状语从句
