Here are some examples of how it can be used in English:
* "He was walking atras." (He was walking behind.)
* "Move the chair atras." (Move the chair backward.)
* "We're atras on schedule." (We're behind schedule.)
However, it's important to note that "atras" is not a common English word. It is more likely to be used in Spanish-speaking communities or in contexts where Spanish is being discussed.
