My report reflects a logical sequence. My introduction is exciting and inviting. My ideas flow and are well connected. I have a satisfying conclusion. Commas surround parenthetical expressions and appositives.
Commas separate the items in a series.
A comma precedes ''and'' or ''but'' when introducing an independent clause. A comma follows an introductory word or phrase. A semi-colon connects two sentences. Closing quotation marks always follow commas and periods. Apostrophes are used correctly to show possession or create contractions.
