error_type: Case Error
error_severity: 1
error_description: Case Error: According to English writing conventions, in the pinyin spelling of Chinese names, the pinyin of the surname and the given name should be separated, and the first letter of each pinyin should be capitalized. In the original sentence, the first letter of the pinyin 〈Gao feng〉 needs to be capitalized, so 〈Gao feng〉 is corrected to 『Gao Feng』 to comply with English name writing conventions.

error_type: Subject-Verb Agreement Error
error_severity: 5
error_description: ① Noun Error: According to the prompt, the intended meaning here is 'football fan'. 〈face〉 means 'face', so 〈face〉 needs to be changed to 『fan』 to ensure semantic accuracy; ② Punctuation Error: According to English grammar rules, 〈Gao feng is a football face〉 and 'he have four footballs' are two independent clauses and should be separated by a 『.』, so the 〈,〉 needs to be replaced with 『.』 to make the sentence structure correct; ③ Subject-Verb Agreement Error: According to English grammar rules, there is a subject-verb agreement error in the original sentence. The subject 〈he〉 is third-person singular, but the verb 〈have〉 is in the third-person plural form. Therefore, the verb 〈have〉 needs to be changed to the third-person singular form 『has』 to maintain subject-verb agreement.

error_sentence: Gao feng is a football face, he have four footballs, he have more football pictule.
correct_sentence: He has four footballs, and he has many football stars' pictures.
error: he have more football pictule
correction: and he has many football stars' pictures
error_type: Conjunction Error
error_severity: 5
error_description: ① Conjunction Error: According to English grammar rules, in the original sentence, 〈he have four footballs〉 and 〈he have more football pictule〉 are clauses containing independent predicate structures, so 『and』 needs to be added to connect them, conforming to English expression habits; ② Subject-Verb Agreement Error: According to English grammar rules, there is a subject-verb agreement error in the original sentence. The subject 〈he〉 is third-person singular, but the verb 〈have〉 is in the third-person plural form. Therefore, the verb 〈have〉 needs to be changed to the third-person singular form 『has』 to maintain subject-verb agreement; ③ Adjective Error: According to the prompt, the intended meaning here is 'many'. In the original sentence, 〈more〉 indicates a comparative degree, but there is no object of comparison in the context; it should be replaced with 『many』, which expresses quantity, to fit the context; ④ Noun Possessive Error: According to the context, the author wants to express 'many photos of soccer stars', so the plural possessive form should be used. This information is missing in the original text, so the plural possessive 『stars'』 needs to be added to comply with grammar and context; ⑤ Spelling Error: According to the sentence meaning, the intention here is to express 'pictures'. 〈pictule〉 is a misspelling of 『pictures』, so 〈pictule〉 needs to be corrected to 『pictures』 to make the sentence meaning clear.

error_sentence: But he never play football, he only watch tv football.
correct_sentence: But he never plays football. He only watches football matches on TV.
error: play football, he only watch tv football
correction: plays football. He only watches football matches on TV
error_type: Noun Number Error
error_severity: 5
error_description: ① Subject-Verb Agreement Error: According to English grammar rules, there is a subject-verb agreement error in the original sentence. The subject 〈he〉 is third-person singular, but the verb 〈play〉 is in the third-person plural form. Therefore, the verb 〈play〉 needs to be changed to the third-person singular form 『plays』 to maintain subject-verb agreement; ② Punctuation Error: According to English grammar rules, the original clauses 〈he never play football〉 and 〈he only watch tv football〉 are independent clauses each containing a subject-verb structure and should be separated by a 『.』. Therefore, the 〈,〉 needs to be replaced with 『.』 to make the sentence structure correct; ③ Subject-Verb Agreement Error: According to English grammar rules, there is a subject-verb agreement error in the original sentence. The subject 〈he〉 is third-person singular, and the verb 〈watch〉 is in the third-person plural form. Therefore, the verb 〈watch〉 needs to be changed to the third-person singular form 『watches』 to maintain subject-verb agreement; ④ Word Order Error: According to the context, the author wants to express 'watches football matches on TV'. The word order in the original phrase 〈watch tv football〉 is incorrect and should be changed to 『watches football matches on TV』 to conform to expression habits; ⑤ Noun Error: According to the prompt, the intended meaning here is 'watch football matches', but the original sentence omits 『matches』. Therefore, 『matches』 needs to be added to match the intended meaning; ⑥ Preposition Error: According to English expression habits, the fixed phrase for 'watch on TV' is 'on TV'. In the original sentence, 〈tv〉 means 'television', so 『on』 needs to be added before 〈tv〉 to comply with English grammar; ⑦ Case Error: According to English writing conventions, the first letter of proper nouns needs to be capitalized. 〈tv〉 is a proper noun representing 'television', so 〈tv〉 needs to be changed to 『TV』 to comply with conventions.
