Dear teacher

?

I am chen, your student in tsinghua University . I am so sorry for my absence in the last English course, for I forgot this important day carelessly. Last week, all the courses, except oral English course, were finished, so I neglected the fact that today is Tuesday. You know, I never miss any course you taught, so please forgive me.

More importantly, I shall appreciate you, for my oral English have been improved so much during this term. You definitely are the one of the best respectable teachers I’ve ever met. Thanks a lot.

Best wish to you
