error_type: Nonfinite Verb Form Error
error_severity: 3
error_description: ① Subject-Verb Agreement Error: According to English grammar rules for third-person singular subjects, the subject 〈She〉 requires the third-person singular form of the verb, so the base verb 〈like〉 is changed to the third-person singular form 『likes』 to form the correct subject-verb structure; ② Nonfinite Verb Form Error: According to English verb collocation rules, when the verb 〈like〉 is followed by another verb expressing an action, the to-infinitive structure is required. Therefore, 『to』 needs to be added before 〈wear〉, changing 〈wear〉 to 『to wear』 to comply with infinitive usage norms; ③ Determiner Error: According to English rules for using singular countable nouns, when the noun 〈shirt〉 appears as a singular countable noun, it must be preceded by a determiner. Therefore, the indefinite article 『a』 needs to be added before 〈blue shirt〉 to comply with article usage norms.

error_sentence: She like wear blue shirt and red shose. She favourite colour is blue and red
correct_sentence: She likes to wear a blue shirt and red shoes. Her favourite colours are blue and red.

error_type: Subject-Verb Agreement Error
error_severity: 5
error_description: ① Spelling Error: According to English spelling norms and noun plural rules, 〈shose〉 is misspelled and needs the plural form to represent the concept of 'shoes', so 〈shose〉 is corrected to the plural noun 『shoes』 (correct spelling and maintaining plural form); ② Pronoun Error: According to English possessive pronoun usage rules, when indicating possession, the subject pronoun 〈She〉 should be changed to the possessive form 『Her』, so it is changed to 『Her』 to correctly modify the noun phrase 'favourite colours'; ③ Noun Number Error: Based on the context expressing multiple colors later, the singular noun 〈colour〉 should be changed to the plural form 『colours』, so it is changed to 『colours』 to maintain semantic consistency; ④ Subject-Verb Agreement Error: According to English grammar rules, the plural subject 〈colours〉 requires a plural linking verb, so the singular form 〈is〉 is changed to the plural form 『are』, forming the correct subject-verb structure 『Her favourite colours are』.

error_sentence: She favourite colour is blue and red
correct_sentence: Her favourite colours are blue and red.
correction: .
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English punctuation norms, declarative sentences must end with a terminal punctuation mark. The original sentence lacks end punctuation, so a period 『.』 needs to be added at the end of the sentence to completely mark the sentence's end, forming a complete sentence structure that conforms to English writing standards.
