error_type: Subject-Verb Agreement Error
error_severity: 3
error_description: Subject-Verb Agreement Error: According to English grammar rules, the subject 〈everyone〉 is third-person singular, so the verb should be in the third-person singular form; therefore, 〈have〉 needs to be changed to 『has』 to comply with the subject-verb agreement principle.

error_sentence: Let me tell you something about my family photow.
correct_sentence: Let me tell you something about my family photo.
error: photow
correction: photo
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: According to English spelling rules, the sentence intends to express 'photo'; thus, 〈photow〉 is an incorrect spelling. The correct spelling should be 『photo』, and the ending letter combination should follow English word formation rules.

error_sentence: First, that tall boy is m father .
correct_sentence: First, that tall man is my father.
error: boy is m
correction: man is my
error_type: Noun Error
error_severity: 3
error_description: ① Noun Error: Based on the sentence's meaning, 『man』 should be used to denote an adult male, whereas 〈boy〉 refers to a minor male, which is inconsistent with the identity of a father; therefore, it should be changed to 『man』; ② Spelling Error: Based on the sentence structure and meaning, 〈m〉 is an incorrect spelling of 'my'; the possessive adjective 『my』 should be used to clarify the possessive relationship.

error_sentence: Second , that beautiful girl is my mother.
correct_sentence: Second, that beautiful woman is my mother.
error: girl
correction: woman
error_type: Noun Error
error_severity: 3
error_description: Noun Error: Based on the sentence's meaning, the noun 『woman』, referring to an adult female, should be used here to match the mother's gender and age and accurately describe the family relationship, whereas 〈girl〉 refers to a minor female, inconsistent with the mother's identity; it should be changed to 『woman』.

error_sentence: She is a elegant an handsome.
correct_sentence: She is elegant and handsome.
error: a elegant an
correction: elegant and
error_type: Determiner Error
error_severity: 4
error_description: ① Determiner Error: According to the sentence's subject-complement structure, the adjectives 〈elegant〉 and 〈handsome〉 used as complements do not require the article 〈a〉 before them; therefore, 『a』 needs to be deleted; ② Spelling Error: According to the sentence structure, parallel adjectives need to be connected by 『and』; therefore, 〈an〉 here should be changed to 『and』.

error_sentence: Third, the little is my big broyher.
correct_sentence: Third, the little one is my big brother.
correction: one
error_type: Noun Error
error_severity: 3
error_description: Noun Error: According to English grammar principles, the adjective 〈little〉 lacks a noun component to modify; therefore, 『one』 needs to be added as a pronoun referring to the previously mentioned family member to complete the meaning.

error_sentence: Third, the little is my big broyher.
correct_sentence: Third, the little one is my big brother.
error: broyher
correction: brother
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: Based on the original sentence 〈Third, the little is my big broyher.〉, it is clear the intention is to express 'brother'; the correct spelling should be 『brother』.

error_sentence: He is a lovely boy , Ilike he very much.
correct_sentence: He is a lovely boy, and I like him very much.
error: Ilike he
correction: and I like him
error_type: Conjunction Error
error_severity: 5
error_description: ① Conjunction Error: Based on the original sentence 〈He is a lovely boy , Ilike he very much.〉, this is a compound sentence requiring 『and』 to connect the two independent clauses; therefore, 『and』 needs to be added after the comma 『,』; ② Space Error: Based on the original sentence, the intention is to express 'I like', but 〈Ilike〉 combines two separate words 〈I〉 and 〈like〉; a space should be added to correct it to 『I like』; ③ Pronoun Error: From the original sentence, the personal pronoun 〈he〉 is intended, but 〈he〉 is a subjective pronoun and cannot function as an object; it should be changed to the objective pronoun 『him』.

error_sentence: Finally, the littly girl is me.
correct_sentence: Finally, the little girl is me.
error: littly
correction: little
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: Based on the original sentence 〈Finally, the littly girl is me.〉, the intention is to express 'little girl'; thus, 〈littly〉 is an incorrect spelling. The correct spelling should be 『little』; attention should be paid to adjective suffix spelling rules.

error_sentence: Me is a pretty girl.
correct_sentence: I am a pretty girl.
error: Me is
correction: I am
error_type: Subject-Verb Agreement Error
error_severity: 3
error_description: ① Pronoun Error: From the original sentence, the first person is needed as the subject, but 〈Me〉 is an objective pronoun and cannot be the subject; 〈Me〉 should be changed to the subjective pronoun 『I』; ② Subject-Verb Agreement Error: When using the first-person pronoun 『I』 as the subject, the linking verb must agree with the person and number of the subject; therefore, 〈is〉 needs to be changed to 『am』.
