error_type: Noun Number Error
error_severity: 2
error_description: Noun Number Error: According to English grammar rules, the noun 〈football〉 in the original sentence should be in the plural form 『footballs』 to agree with the number 〈four〉, therefore 〈football〉 should be changed to 『footballs』 to comply with English grammar rules.

error_type: Subject-Verb Agreement Error
error_severity: 5
error_description: ① Subject-Verb Agreement Error: According to English grammar rules, the original sentence has a subject-verb agreement error; the subject 〈He〉 is third-person singular, while the verb 〈see〉 is in the third-person plural form, thus the verb 〈see〉 needs to be changed to the third-person singular form 『sees』 to maintain subject-verb agreement; ② Noun Number Error: According to English grammar rules and context, the meaning here is 'watching football matches', implying more than one match, so the plural form of the noun should be used, but 〈match〉 is singular in the original sentence, hence it needs to be changed to 『matches』 to align with the context of watching multiple matches; ③ Conjunction Error: According to English expression conventions, the meaning here is 'when watching TV', but 〈in watch TV〉 does not fit the meaning, therefore the conjunction 『when』 is used to connect the action 『watching TV』 to express the time relationship.

But〉 is changed to 『, but』 to comply with expression conventions; ② Subject-Verb Agreement Error: According to English grammar rules, the original sentence has a subject-verb agreement error; the subject 〈he〉 is third-person singular, while the auxiliary verb 〈do〉 is in the third-person plural form, thus the verb 〈do〉 needs to be changed to the third-person singular form 『does』 to maintain subject-verb agreement.
