Lesson 339

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.
