请为短文纠错！（快）

第一句back与returning重复，所以应该去掉back,第二句应该是现在完成时，应该把had改为have,第三句不能说wery much interesting，应该说I am very interested in your lecture,下一句，在wonder that 后面应该加上if,表示选择，疑问
呵呵，不确定，不过只能想到这儿了啊，楼上说的也对，possible拼写也错了，呵呵

原文：
My uncle is returning back home from France,and I had promised to meet him at an airport at 3:30 tomorrow afternoon.I am very much interesting in your lecture.I wonder that it is possiable for the talk to be recorded.
修改：
My uncle is return home from France,and I have promised to meet him at the airport at 3:30 tomorrow afternoon.I am very interesting in your lecture.I wonder that it is possible for the talk to be recorded.

My uncle is returning home from France,and I promised to meet him at the airport at 3:30 p.m.tomorrow. I am very interested in your lecture.I wonder if it is possible for the talk to be recorded.

没记错的话应该是中学作文题吧 I am very interested in your lecture.好象不符题意哦，是一个外国教授演讲，“我”请求老师帮忙记录，your→the吧。

严格点，呵呵，错误一： return 本身就是“回来
