error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: According to English spelling conventions, 〈classmater〉 is not the correct spelling for 'classmate'. The word should be 『classmate』, so the incorrect spelling 〈classmater〉 is corrected to 『classmate』 to ensure accurate word structure.
error_sentence: Today she wear pink shirt with a rabbit on it.
correct_sentence: Today she wears a pink shirt with a rabbit on it.
error: wear
correction: wears a
error_type: Subject-Verb Agreement Error
error_severity: 4
error_description: ① Subject-Verb Agreement Error: According to English grammar rules, when the subject is the third-person singular 〈she〉, the verb must take the corresponding third-person singular form. The base verb 〈wear〉 does not conform to this rule, so it is corrected to the third-person singular form 『wears』, forming the correct subject-verb structure 『she wears』; ② Determiner Error: According to English article usage rules, a singular countable noun like 〈shirt〉 must be preceded by a determiner when used generically. Since it refers to a shirt in general here, not a specific one, the indefinite article 『a』 needs to be added, forming the grammatically correct expression 『wears a pink shirt』.
error_sentence: she wear a yellow shoes .
correct_sentence: She wears yellow shoes.
error: she wear a
correction: She wears
error_type: Verb Tense Error
error_severity: 5
error_description: ① Case Error: According to English writing conventions, the first letter of the first word in a sentence must be capitalized. Therefore, the lowercase 〈she〉 at the beginning of the sentence is corrected to the capitalized 『She』 to meet English writing standards; ② Subject-Verb Agreement Error: According to English grammar rules for the third-person singular, the subject 〈She〉 is a singular pronoun, and its verb must be in the third-person singular form. Thus, the base verb 〈wear〉 is changed to the third-person singular form 『wears』, forming the correct structure 『She wears』; ③ Determiner Error: According to English article rules, the indefinite article 〈a〉 is only used to modify singular countable nouns. The plural noun 〈shoes〉 should not be preceded by an indefinite article, so the incorrect 〈a〉 is deleted.
error_sentence: I like she
correct_sentence: I like her.
error: she
correction: her.
error_type: Pronoun Error
error_severity: 3
error_description: ① Pronoun Error: According to English grammar rules, the transitive verb 〈like〉 must be followed by an objective pronoun as its object. The subjective pronoun 〈she〉 can only function as a subject, so it is changed to the objective form 『her』, forming the correct structure 『like her』 to comply with pronoun case usage rules; ② Punctuation Error: According to English writing conventions, a complete sentence with a subject-verb-object structure should end with a period for completeness and correctness, thus changing 〈she〉 to 『her.』.
