In 33-3 quiz, I did very good because it was so easy and It was about misuses of the comma. So, I will talk about four basic of using the comma. First of all, use a comma before and, but, or, for, nor, so, and yet when they connect two independent clauses. For example, the cook got sick, but dinner was served anyway. Second, Use a comma after one or more introductory words that come before your main sentence. For example, When she saw her grade, she was glad. So, I will continue the rest of four basic rules of using the comma in next blog.
