Composition

[이름], I don\'t have any problems answering your

questions so never hesitate, OK?

However, if I wasn\'t able to explain it well, tell me so.

As I said before, there are times that a teacher also

cannot explain things well. So, please inform

me as well.

Thank you my dear, [이름].

Dear Teacher,
>> Correct
After checking your correction, I have some questions again. 

>> Correct
 A is what I wrote this morning. 

>> Correct
 B is what you corrected. 

>> Correct
 C is my new question.

>> Correct
 A. People nowadays can\'t avoid from using computers and smart phones for an entire day so it leads our eyes to feel painful.
B. People nowadays can\'t avoid from using computers and smart phones for an entire day so it leads our eyes to feel pain.
C. I thought I could use \'feel painful\' in this sentence because what I wanted to say is that my eyes are painful, so I feel pain.
>> Correct

Your eyes are painful. = be verb + painful

I feel pain. = feel + pain

Remember the sentence pattern so you won\'t be confused.^^
 I am a little bit confused again. ㅠㅠ

>> Correct
Maybe, are we only able to use \'be painful\' not \'feel painful\'? 

>> Correct
 You already told me like something is painful so I feel pain. 

>> Correct (Something + be verb + painful.)
 At that time, I thought I totally understood about this usage but I still need to study more. ^^;;

>> Correct
 See you tomorrow!
