error_description: ① Noun Error: According to the prompt requirements, to describe a classmate's attire, the original sentence's 〈student〉 means "student", which is a noun error, so 〈student〉 needs to be changed to 『classmate』 to meet the prompt requirements; ② Subject-Verb Agreement Error: According to English grammar rules, the original sentence has a subject-verb agreement error; the subject 『classmate』 is third-person singular, and the original predicate 〈like〉 is in the third-person plural form, so the verb 〈like〉 needs to be changed to the third-person singular form 『likes』 to maintain subject-verb agreement; ③ Determiner Error: According to English grammar rules, a countable singular noun must be preceded by an article; the original sentence is missing the necessary determiner 『a』 before 〈shirt〉, therefore, the phrase is changed to 『a red shirt』 to comply with English grammar rules.

error_description: ① Pronoun Error: According to the meaning of the sentence, the intention here is to express "her"; in the original sentence, 〈she〉 as a subject pronoun cannot modify a noun, so 〈she〉 is changed to 『her』 to indicate possession and fit the context; ② Punctuation Error: According to English expression habits, no punctuation mark is needed before 〈Because〉, so 〈, Because〉 is changed to 『because』 to eliminate the comma separation issue; ③ Subject-Verb Agreement Error: According to English grammar rules, the original sentence has a subject-verb agreement error; the subject 〈shoes〉 is third-person plural, and the original predicate 〈is〉 is in the third-person singular form, so the verb 〈is〉 needs to be changed to the third-person plural form 『are』 to maintain subject-verb agreement.
