Never turn in a written work to a teacher without keeping a copy for yourself. Never throw away your work until after you have received your grade. If you think you might ask the teacher later for a recommendation, you want to keep your written work to remind the teacher of you when you ask for a letter. Copy lines of poetry with line-breaks exactly as they are in your text. Commas come before and , but , or , nor , such as , and before and after for example .
Commas serve to bracket a phrase or a clause.
If the phrase or clause begins or ends a sentence, one of the commas is suppressed. Do not separate a subject and its verb by a comma. Use a semicolon to separate two independent clauses, NOT a comma. Write about what happens in a fiction in the present tense. Verbs are the first place to work to improve your writing style.
