error_type: Subject-Verb Agreement Error
error_severity: 3
error_description: Subject-Verb Agreement Error: According to English grammar rules, when the subject 〈Amy〉 is a third-person singular noun, the predicate verb must take the singular form; therefore, the base form verb 〈like〉 is changed to the third-person singular form 『likes』 to ensure subject-verb agreement in number and person.

error_sentence: She like wearing every day.
correct_sentence: She likes wearing them every day.
error: like wearing
correction: likes wearing them
error_type: Subject-Verb Agreement Error
error_severity: 5
error_description: ① Subject-Verb Agreement Error: According to English grammar rules, when the subject 〈She〉 is a third-person singular pronoun, the predicate verb must take the corresponding singular form; therefore, the base form verb 〈like〉 is changed to the third-person singular form 『likes』 to maintain agreement between the subject and verb in person and number; ② Pronoun Error: Based on context and English grammar requirements, the verb phrase 〈wearing〉, acting as a transitive verb, needs an object; therefore, the pronoun 『them』 is added to refer to the previously mentioned 〈pink shirt and pink shoes〉, making the sentence structure complete and the meaning clear.

error_sentence: She looks in pink is very beautiful.
correct_sentence: She looks very beautiful in pink.
error: in pink is
error_type: Sentence Structure Error
error_severity: 3
error_description: Sentence Structure Error: According to English grammar rules, a simple sentence can only contain one main predicate verb. The original sentence 〈She looks in pink is very beautiful〉 contains two predicate verbs, 〈looks〉 and 〈is〉, resulting in a run-on sentence structure. It is necessary to delete 〈is〉 to simplify the sentence structure and make the expression clear.

error_sentence: She looks in pink is very beautiful.
correct_sentence: She looks very beautiful in pink.
correction: in pink
error_type: Word Order Error
error_severity: 3
error_description: Word Order Error: According to English syntax rules, when a sentence contains both the predicate verb 〈looks〉 and the adjective complement 〈very beautiful〉, the prepositional phrase 〈in pink〉 indicating manner of dress, acting as an adverbial, should be placed at the end of the sentence to modify the entire predicate part. Therefore, the original disordered structure is adjusted to the standard word order 『She looks very beautiful in pink』 (She looks very beautiful wearing pink), ensuring the sentence components align with the basic English sentence structure of 'Subject + Predicate + Complement + Adverbial', while maintaining semantic integrity and natural expression.
