答案

a.m.、p.m.、etc.是缩写词,有关标点符号的用法如下：
出现在句尾时,如果句尾是句点（句号）,则句点（句号）可省略,但a.m.、p.m.、etc.本身后面的点需保留,如（1）.如果句尾是问号,则不可省略a.m.、p.m.、etc.后面的点以及问号.
出现在句中,或者后面接逗号、破折号、冒号时,a.m.、p.m.、etc.的点不可省略,如（2）（3）（4）.
（1）Yorktown Daily is slowing updates as the storm moves through Virginia,effectively stopping regular updates at 10 p.m.
