Use your question. Your question uses sentence in a sentence.
------------------------------------------------------------------
Previous Answer:
You should write it like an exclamatory: I don't know how to write sentence!
Imperative (question): Do you know how to write a sentence?
Or just plain old sentence: I wrote a run-on sentence.
'A' or 'an' if the word starts with a vowel sound, is called a determiner; it tells you that the noun after it is just one. Example:
A boy and a dog walked down the sidewalk. (one boy and one dog)
You is either a direct address (second person) or a protocol established for general comments, e.g. "You don't see those around much anymore."
"I love you."
"You are looking for trouble."
"You and your brother should end your quarrel."
"So you are coming to the match or what??
"Are you coming in?" She asked.
" Do you want to come in the haunted house?" Asked John.
i do not know how to use embalming in a sentence. (there is the sentence)
So- you are asking when to use 'when' in a sentence. When you are asking how to use when in a question, you are already using when in a sentence, because a question actually is a sentence. I like to use when in a sentence whenever I like.
