Mechanics - Punctuation - Periods
Use a period with abbreviations used with figures showing time.
Examples: A.M., P.M., B.C., A.D.
Instructions: Put periods where needed in the following sentences.
1. I was born in A D 1940.
2. Be here at 4:30 A M , or you will not see me until 9:45 P M
3. What happened in A D 1776 that was of great importance?
4. People living in 2000 B C did not enjoy all that we have today.
5. Class starts promptly at 8:00 A M
Note: When a period is used for an abbreviation or some other reason at the end of the sentence, you do not need a second one to end the sentence. The one period does double duty.
