Examples of past tense verbs are: walked, stopped, looked, pushed
If you were writing an essay about why you need to look both ways before crossing the street, here is an example of how you could use these verbs:
"Laurence walked home from school one day and he forgot to look both ways before crossing the street. A car started coming near him and he almost got hit! He stopped right away. This is one reason why looking both ways is important, to stay safe. "
Hope this helps!
