Here is point 4 & 5. I hope these are helping you understand how to emphasize what you want emphasized.
4. Subordinate conjunction subordinate or weaken the clause they introduce. They make the clause dependent on another clause, one which can stand alone. Example: "when we come home late" cannot stand on its own be and understood. (Common subordinate conjunctions: if, because, after, before, since, when). Only subordinate an unimportant clause. Not an important one!
5. Humans always remember the last word they've read. Just as we build a plot to a climax, every sentence reaches a climax at its end. Save the best to be used as a last word.
See you tomorrow!
