error_type: Noun Error
error_severity: 5
error_description: ① Noun Error: According to the context, 〈people〉 in 〈football people〉 generally refers to "people in the football world", but a more precise expression for football stars is needed here, so the common noun 〈people〉 is changed to the specific noun 『stars』 for accurate meaning; ② Noun Possessive Error: According to English grammar rules, the possessive form is needed to indicate possession, so the common noun 〈stars〉 is changed to the possessive form 『stars'』 to modify the following noun; ③ Noun Number Error: According to the sentence meaning, 〈photo〉 refers to multiple photos and needs to be in the plural form for general reference, so the singular countable noun 〈photo〉 is changed to the plural noun 『photos』 to conform to logical semantics.

error_sentence: He has 4 footballs, and he has many football people photo, but he doesn't play football, he likes looking ply football on TV.

error_type: Word Redundancy Error
error_severity: 5
error_description: ① Punctuation Error: According to English grammar rules, a comma 〈,〉 cannot connect two independent clauses (i.e., two complete sentences), so the comma should be changed to a period 『.』 to correctly separate the sentence structures; ② Case Error: According to English writing conventions, the first letter of the first word in a sentence must be capitalized, so the lowercase form 〈he〉 is changed to the uppercase form 『He』 to ensure correct format; ③ Verb Choice Error: According to the context semantics, 〈looking〉 does not collocate well with 〈football〉; it should be changed to the more logical verb 『watching』 to accurately express the meaning of "watching football"; ④ Word Redundancy Error: 〈ply〉 has no actual meaning in this context and does not conform to expression habits; it should be deleted directly to keep the sentence concise; ⑤ Noun Error: According to the sentence meaning, it is necessary to specify that the object being watched is "football games", so the countable noun 『games』 is added to make the expression more complete, i.e., modified to 『watching football games』.
