英语句子成分I feel grateful for your offering me the post of sales

1 your offering 和allowing都是动名词,在这里分别是介词宾语和动词宾语.2 以下的表达法或许比你的原句更好：1 I feel grateful （to you）for BEING OFFERED the post of sales manager.2 I would appreciate BEING...

your：形容词性物主代词,用来修饰offering和allowaing;
offering、allowing :动名词，是所在句子的宾语。
还可以这样说：
I feel grateful for you offering me the post of sales manager.
I would appreciate you allowing me to take a make-up examination.

动名词接物主代词,

我很感激你提供这份销售经理的职位.
我很感激你准许我参加补考.

首先your肯定是形容词，offering和allowing是句子语法grate for sb dong sth 和 appreciate sb doing sth的动词ing形式，不是名词，而是动词。。
