error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: According to English time expression norms, 〈Lst〉 is an incorrect abbreviation; the correct spelling should be the full adjective 『Last』 (meaning 'the previous one'), which needs correction to avoid ambiguity; The noun for the day of the week 〈Saterday〉 has transposed vowel letters; the correct spelling is 『Saturday』, meaning 'Saturday'. This word is frequently misspelled and requires reinforcement.

error_type: Conjunction Error
error_severity: 3
error_description: Conjunction Error: According to English parallel sentence writing norms, a comma 〈,〉 cannot solely connect two independent clauses 〈went to the park〉 and 〈played with friends〉; this usage constitutes a typical comma splice error. A conjunction 『and』 is needed in the middle to maintain sentence coherence, rather than simply separating them with a comma 〈,〉.
error_sentence: In the afternon, I played basketball, I love baskerball, it'sexciting.
correct_sentence: In the afternoon, I played basketball.
error: afternon
correction: afternoon
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: According to English word spelling norms, 〈afternon〉 is missing the letter 〈o〉; the correct spelling should be 『afternoon』, meaning 'afternoon', conforming to the word formation rule for this time noun (after + noon).
error_sentence: In the afternon, I played basketball, I love baskerball, it'sexciting.
correct_sentence: In the afternoon, I played basketball.
error: ,
correction: .
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English grammar rules, 〈I played basketball〉 and 〈I love basketball〉 are two independent complete clauses and cannot be connected solely by a comma 〈,〉. To ensure clear sentence structure and avoid a comma splice error, the connecting comma should be changed to a period 『.』 to separate them.
error_sentence: In the afternon, I played basketball, I love baskerball, it'sexciting.
correct_sentence: I love basketball. It's exciting.
error: baskerball, it'sexciting
correction: basketball. It's exciting
error_type: Punctuation Error
error_severity: 3
error_description: ① Spelling Error: According to English vocabulary spelling rules, 〈baskerball〉 is not the correct spelling for the sport; the misspelled 〈baskerball〉 should be corrected to 『basketball』 to conform to English writing standards; ② Punctuation Error: According to English sentence structure rules, 『It's exciting』 and the preceding clause are two independent sentences and need to be separated into complete sentences. Therefore, the comma 〈,〉 should be changed to a period 『.』 to separate the clauses, and the first letter capitalized to 『It's』; ③ Space Error: According to English sentence structure rules, 〈it'sexciting〉 lacks the necessary space between words; a space needs to be added between 『It's』 and 『exciting』.
error_sentence: In the last Sunday's evening, I watched TV.
correct_sentence: Last Sunday evening, I watched TV.
error: In the last Sunday's
correction: Last Sunday
error_type: Word Redundancy Error
error_severity: 5
error_description: ① Word Redundancy Error: According to English time expression norms, 〈In the last Sunday's evening〉 has a double determiner issue. 『Last Sunday』 itself already provides a clear time indication, so the redundant prepositional phrase 〈In the〉 should be deleted for conciseness; ② Noun Possessive Error: According to the fixed collocation rules for time phrases, 〈Sunday evening〉 as a whole adverbial phrase of time does not require the possessive form. Delete 〈's〉 and modify to 『last Sunday evening』 to maintain semantic integrity and conform to idiomatic English expression.
