Therefore, the simple past tense verb 『swam』 should be changed to the gerund 『swimming』 to comply with English grammar rules.

Therefore, the definite article 『the』 needs to be added before 〈seaside〉 here to indicate specificity and comply with grammar rules; ② Spelling Error: According to the original sentence's meaning, it intends to express 'go to the seaside'. The correct spelling for '海边' is 'seaside', so the incorrect spelling 〈seside〉 needs to be changed to 『seaside』 to conform to word spelling norms and the original meaning; ③ Punctuation Error: According to English syntax rules, the clauses 'and my parents and I went to the seaside' and 'I'm so excited that...' contain independent subject-verb structures and belong to two different idea groups, thus needing to be separate sentences, separated by a period. 〈,〉 should be changed to 『.』 to comply with English syntax rules; ④ Space Error: According to English syntax rules, sentences need to be separated by punctuation and a space to avoid run-on sentences. Therefore, a space needs to be added after 〈.〉 and before 〈I〉; ⑤ Verb Tense Error: According to the context, describing past events requires the simple past tense of the predicate verb. Therefore, the simple present tense 〈I'm〉 needs to be changed to the simple past tense 『I was』 to conform to the contextual tense.
