error_type: Subject-Verb Agreement Error
error_severity: 3
error_description: Subject-Verb Agreement Error: According to English grammar rules, the subject 〈My classmate〉 is a third-person singular noun, requiring the verb to be in its corresponding third-person singular form. The original sentence uses the base form 〈wear〉, which violates the subject-verb agreement principle; it should be changed to 『wears』, correcting the phrase to 『My classmate wears...』 to ensure grammatical accuracy.

error_sentence: She look likes very beautiful.
correct_sentence: She looks very beautiful.
error: look likes
correction: looks
error_type: Word Redundancy Error
error_severity: 4
error_description: ① Subject-Verb Agreement Error: According to the rules for the third-person singular present tense in English grammar, the subject 〈She〉 requires the predicate verb to be in the singular form. The original sentence's base form verb 〈look〉 should be changed to the third-person singular form 『looks』, correcting the phrase to 『She looks...』 to ensure subject-verb agreement; ② Word Redundancy Error: When describing appearance, 〈looks〉 already fully conveys the meaning of 'appears', making the subsequent 〈likes〉 a redundant expression with repetitive meaning. According to the principle of conciseness in English expression, the redundant word 〈likes〉 should be deleted to make the sentence more economical. The final correction is: 『She looks beautiful.』.

error_sentence: She with long hair and big eyes.
correct_sentence: She has long hair and big eyes.
error: with
correction: has
error_type: Verb Choice Error
error_severity: 3
error_description: Verb Choice Error: When describing a person's physical features, according to English expression conventions, the verb 『has』 should be used to indicate possession, rather than the preposition 〈with〉 which indicates accompaniment. Therefore, 〈with long hair〉 should be changed to 『has long hair』 to make the expression more idiomatic in English. The final complete sentence is: 『She has long hair.』.

error_sentence: I know she likes black and pink
correct_sentence: I know she likes black and pink.
correction: .
error_type: Punctuation Error
error_severity: 1
error_description: Punctuation Error: According to English sentence structure rules, the declarative sentence 〈I know she likes black and pink〉, being a complete independent clause, must end with a terminal punctuation mark. Therefore, a period needs to be added to comply with English punctuation standards, correcting it to 『I know she likes black and pink.』.
