Here is the sentence:
Danny loved going to the beach. He watched beautiful women in skimpy bikinis,
ate fresh seafood, and
swum in the refreshing water. After a shark
bit his leg, however, Danny preferred the
pool at his apartment complex.
The second verb, swum, is incorrect. As you know, the sentence requires the simple past form, swam, because there are no auxiliary verbs. Swim is an irregular verb; the chart below shows its forms.
| Verb | Simple Present | Simple Past | Past Participle |
| swim | swim(s) | swam | swum |
