请英语好的朋友帮助纠正一下翻译错误：“Dear Professor: 我没有收到你。。。”

I Know i maybe bother you too much times about these kind things. I feel truly sorry about this.

改成
I feel truly sorry to bother you so many times about this.

最后写I will appreciate it very much.

语法上就是much times -->many times
appreciate-->appreciate it
其他只是我的建议，您可以随意。

------------------------------------------------
看了楼上的回复我发现这里也是要改的
But could you take some time recheck my exactly exam paper again, since i really can't believe I got a such low mark.

take some time to recheck
然后exactly是副词，不能修饰名词，所以去掉就可以了
然后,改成? 后面since的s改成大写
然后a such low mark改成such a low mark，这个也是语法问题

Dear Professor,

I haven't received your reply yet. I bet my previous request has been rejected.

But I hope you could take some time to double check my final examination paper since I still can't believe I got such a low score against this course.

I feel truly sorry for bothering you so many times about this matter. But this result means much for me.

I will appreciate so much if you could do me the favor.

Sincerely yours,
XXXXX

But could you take some time recheck my exactly exam paper again,
it take some time to do 固定搭配
sb spent some time on/for sth
I Know i maybe bother you too much times about these kind things.
Know 不要大写
跟老外打交道不要太委婉,不要说你估计你得申请被拒绝,模凌两可的回答不好

rely依赖，应是reply
可以把previous去掉
could you please take some time to my exam···
such low marks

so many this kind of thing
this换成it
this will be my last time to request you like this

will be very appreciate if you could help me
