before的反义词英文怎么写？

"Before" denotes something happening or existing prior to a particular event or time, while "after" refers to something occurring subsequently or later on. For example, if we say "I arrived before the party started," it means that I reached the location prior to the commencement of the party. On the other hand, if we say "I arrived after the party started," it implies that I reached the location subsequent to the commencement of the party. The words "before" and "after" are often used to indicate the sequence of events or the chronological order of occurrences. It is essential to understand the difference between these two terms to accurately comprehend the temporal relationship between different actions or incidents.
