Error analysis:
error_sentence: In the afternoon I played in the park with my friend then palyed basketball .
correct_sentence: In the afternoon I played in the park with my friends and then played basketball.
error: friend then palyed
correction: friends and then played
error_type: Conjunction Error
error_severity: 4
error_description: ① Noun Number Error: In English, when a sentence implies multiple objects, the noun should be in plural form. The noun 〈friend〉 in the sentence implies multiple friends and should be changed to the plural form 『friends』; ② Conjunction Error: The sentence contains two verb phrases 〈played in the park〉 and “played basketball”; the conjunction 『and』 is needed to connect the two verb phrases within one sentence for grammatical correctness; ③ Spelling Error: According to the context, the intended meaning is "played basketball," so the verb 〈palyed〉 is a misspelling of the past tense verb 『played』; therefore, 〈palyed〉 is corrected to 『played』 to fit the meaning.

error_sentence: At 10:00a.m., I cleaned my room.
correct_sentence: At 10:00 a.m., I cleaned my room.
error: 10:00a.m.
correction: 10:00 a.m.
error_type: Space Error
error_severity: 1
error_description: Space Error: According to English writing rules, a space should be added between the number and “a.m.” or “p.m.” in time expressions to conform to standard writing format. The time expression 〈10:00a.m.〉 in the original sentence lacks the necessary space; therefore, a space should be added between 〈10:00〉 and 〈a.m.〉, changing it to 『10:00 a.m.』 to comply with writing conventions.

error_sentence: In the evening I was wacth TV
correct_sentence: In the evening, I watched TV.
error: I was wacth TV
correction: , I watched TV.
error_type: Verb Tense Error
error_severity: 4
error_description: ① Punctuation Error: According to English punctuation rules, a comma is needed to separate an introductory time adverbial phrase from the main clause. The original sentence lacks a comma between 〈In the evening〉 and the main clause; therefore, a comma 『,』 should be added after 〈In the evening〉 to follow English expression conventions; ② Verb Tense Error: Based on the context, the entire text describes past events and should use the simple past tense. The phrase 〈was wacth〉 in the sentence uses an incorrect tense combination; it should be changed to the simple past tense 『watched』 to match the tense of the context; ③ Spelling Error: According to the intended meaning, the phrase expresses "watch TV," so 〈wacth〉 is a misspelling of the verb 『watch』; 〈wacth〉 is corrected to 『watch』 and used in the simple past tense 『watched』; ④ Punctuation Error: The clause 〈I watched TV〉 forms a complete sentence structure and requires end punctuation; therefore, a period 『.』 should be added at the end to comply with English writing rules.
