想请教你， stating theterms on which she would be employed这里作独立主格，还是现在分词表伴随？

Shortly after her eighteenth birthday Maria received a letter from Mrs Hutchinson, the wife of an advertising executive, stating theterms on which she would be employed.

Shortly after her eighteenth birthday 是状语修饰received
Maria是主语 received 是谓语a letter 是宾语from Mrs Hutchinson是定语,
the wife of an advertising executive是同位语说明Mrs Hutchinson,
stating the terms on which she would be employed.是非限制性定语修饰a letter
不是独立主格结构因为没有自带逻辑主语。本句stating的逻辑主语是a letter

现在分词作后置定语修饰letter the wife of an advertising executive只是Mrs Hutchinson的同位语 反驳另一位的说法，他说的是定语从句和同位语从句的区分，这两个是易混的，但还没听说过把定语和同位语当成易混知识的，现在分词能作定状表补，但不能作同位语，同位语的定义首先就是一个具有名词性质的单词或短语，不可能由一个现在分词充当 引导词是引导从句的词，这里不是定语从句而是现在分词作定语，如果要改成定语从句那么a letter stating the terms要改成a letter which stated the terms，引导词是which，这里因为原句中stating the terms on which she would be employed太长所以没有紧跟a letter，而是放到句末避免句子不协调 望采纳

独立主格要有主格啊。。。比如A girl came in,book in hand.那个book就是主格 stating the terms on which she would be employed 这里面哪来的主格？ 而现在分词作伴随状语是修饰动词的 你这里谓语动词是received 和后面的stating...八竿子打不着 这个stating...的成分很明显是修饰a letter的 楼上说对了一半 结论：stating the terms on which she would be employed作同位语修饰a letter 定语和同位语的区别：定语修饰名词或限定名词的范围 而同位语阐述名词本身的内容 比如这里的stating...充分说明了信的内容 所以是同位语
