error_type: Spelling Error
error_severity: 1
error_description: Spelling Error: According to the Pinyin spelling rules for Chinese names, the surname and given name should be written separately. The original writing 〈XiaoFan〉 incorrectly combines the surname and given name, violating the standard format for Pinyin transliteration of Chinese names. Therefore, a space needs to be added between the surname and the given name, correcting it to 『Xiao Fan』 which conforms to international standards.

error_sentence: She like pink.
correct_sentence: She likes pink.
error: like
correction: likes
error_type: Subject-Verb Agreement Error
error_severity: 3
error_description: Subject-Verb Agreement Error: According to English grammar rules for third-person singular verb conjugation, when the subject 〈She〉 is a third-person singular pronoun, the verb must take the corresponding third-person singular form. The base form verb 〈like〉 in the original sentence does not meet this requirement, so it needs to be corrected by adding the suffix -s to form 『likes』, creating the correct subject-verb structure 『She likes』.

error_sentence: She wear pink shirt and shoes.
correct_sentence: She wears a pink shirt and shoes.
error: wear
correction: wears a
error_type: Subject-Verb Agreement Error
error_severity: 4
error_description: ① Subject-Verb Agreement Error: According to English rules for third-person singular verb conjugation, when the subject 〈She〉 is a third-person singular pronoun, the verb must take the corresponding third-person singular form. The base form verb 〈wear〉 in the original sentence is not conjugated, so it needs to be corrected by adding the suffix 『-s』 to form 『wears』, creating the grammatically correct subject-verb structure 『She wears』; ② Determiner Error: According to English rules for singular countable nouns, the singular countable noun 〈shirt〉 must be accompanied by a determiner when used alone in a sentence. The original sentence lacks the necessary article, so the indefinite article 『a』 needs to be added to form the complete noun phrase 『a shirt』, satisfying the grammatical requirement that singular countable nouns usually cannot stand alone.

error_sentence: It looks beautiful.
correct_sentence: She looks beautiful.
error: It
correction: She
error_type: Pronoun Error
error_severity: 3
error_description: Pronoun Error: According to the principle of pronoun agreement in English, when a pronoun refers to the previously mentioned female subject 〈She〉, it must maintain consistency in person (third), number (singular), and gender (female). The inanimate pronoun 〈It〉 used in the original sentence does not logically refer to a person, so it needs to be corrected to the personal pronoun 『She』 that matches the subject, ensuring the accuracy of the reference.
