"I am writing this letter to tell you..." would be correct.
When you are just beginning a letter, you have not yet written it. You don't refer to the act of writing as something that has already happened--that is, something in the past.
If you were to use this expression at the end of a letter, you might say "I wrote...," but by then it should not be necessary to state the subject of the letter. It has already been presented.
It would be even better just to go ahead and deliver the message without any such introduction as "I am writing this letter."
I was writing 'there' when I was right there in the open area. Are you there? You there! There now!
Receivers address on the right. I do not think a return address is necessary. I believe the rest of the format should be like writing a note or a letter.
The sentence is nearly correct, but it should be "How did your paper go?" with a capital letter at the beginning and a question mark at the end.
I'm writing on papyrus right now!
You should probably just right to I love you or will you go out with me or just will you dance with me at the next ball, stuff like that
the mean of inconvenience
No. It should be "Is the grammar right in this sentence?"
No. Maybe it should be: They are absolutely right. - They're absolutely right.
If you are referencing yourself, "i" should always, always, always be capitalized. Me = I. When referring to yourself, the "i" should be capitalized even if it is not at the beginning of the sentence. Example: Dave and I went to the store. Remember, just because a word has the letter "i" in it does not mean that the "i" should be capitalized. Example: She used It. (wrong) She used it. (right) The "i" is capitalized only when referring to yourself. In other words, when "I" means "me" or yourself.
If she knew that you had plagiarised this sentence, your teacher should get into a right lather.
"Winning is an habit" is not a right sentence. It should be winning is a habit.
The sentence, 'When you slept you write this sentence', makes no sense. No one writes while asleep. More accurate might be these sentences: After I awoke, I wrote my sentence. When I slept, I dreamed about writing a sentence.
