请问曹老师：
A beautiful girl about my age, she bought the ticket for me when hearing that I had lost my wallet.
A fellow Georgian, Jordan was well known as a friend of the President.
1. 以上两句句首逗号前的部分均可以看作主语的同位语吗？这种前置表示强调？
The conjunction “that” has no 百度竞价推广antic meaning but only a functional meaning, i.e. it constitutes the grammatical means of joining two clauses.
2. i.e.后面为何没逗号？该句子来自章教授的语法书。
（Being）Abeautiful girl about my age, she bought the ticket for me when hearing that Ihad lost my wallet.
（Being）A fellowGeorgian, Jordan was well known as a friend of the President.
这个二个句首的名词词组都不可以剖析为同位语，由于同位语都是在先行词之后的。关于这种名词词组到底是什么成分，不同语法书有不同剖析。我觉得最简单且适当的讲解应该是：这是目前分词短语作状语省略了Being。因为已经看不到目前分词了，于是就剖析为名词词组作状语。你可以试一试加上being，意思完全一样。自己理解了即可，不必纠结到底是什么成分。语法家对此都没统一的认识，作为英语学习者就更没必要去为此烦恼了。
i.e.是拉丁语 id est 的缩写，等于英语的namely，也就是、即。后面用或者不需要逗号均可。不少词典的例句中就没逗号的。
