error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English grammar rules, 〈Today is Monday〉 and 〈I saw my classmates at school〉 are two independent clauses and should be separated by a 『.』; therefore, 〈,〉 needs to be replaced with 『.』 to make the sentence structure correct.

error_sentence: Today is Monday, I saw my classmates at school.

error_type: Noun Number Error
error_severity: 3
error_description: Noun Number Error: Based on the context, the noun 〈classmates〉 in the original sentence should be in the singular form 『classmate』 to be consistent with the third-person singular subject in the following sentence; therefore, 〈classmates〉 should be changed to 『classmate』 for subject-verb agreement.

error_sentence: He in wearing a pure white shirt today and blue shoes today.
correct_sentence: He is wearing a pure white shirt and blue shoes today.
error: in
correction: is
error_type: Auxiliary Error
error_severity: 3
error_description: Auxiliary Error: According to English grammar rules, the structure for the present continuous tense is 'be doing'. The word 〈in〉 in the original sentence does not fit the grammatical structure; therefore, 〈in〉 needs to be changed to the auxiliary verb 『is』 to meet the tense requirement.

error_sentence: He in wearing a pure white shirt today and blue shoes today.
correct_sentence: He is wearing a pure white shirt and blue shoes today.
error: today
error_type: Word Redundancy Error
error_severity: 4
error_description: Word Redundancy Error: According to English expression conventions, a word repeated twice only needs to be kept once. The word 〈today〉 appears twice in the original sentence; therefore, deleting the first redundant 〈today〉 makes the sentence more concise without affecting its meaning.

error_sentence: He live clour blue.
correct_sentence: He loves the colour blue.
error: live clour
correction: loves the colour
error_type: Verb Choice Error
error_severity: 5
error_description: ① Verb Choice Error: Based on the sentence meaning, the intention is to express 'like' or 'love'. The word 〈live〉 in the original sentence means 'reside', which does not fit the context; therefore, it needs to be changed to 'love' to match the context.; ② Subject-Verb Agreement Error: Since the subject is third-person singular, the verb should be in the third-person singular form 'loves'.; ③ Determiner Error: According to English grammar rules, an abstract noun requires the determiner 『the』 for specific reference. In the original sentence, 〈clour〉 is an abstract noun, so 『the』 needs to be added before it for grammatical correctness.; ④ Spelling Error: Based on the sentence meaning, the intention is to express 'color'. 〈clour〉 is a misspelling of 『colour』; it needs to be corrected to 『colour』 for the sentence to make sense.

error_sentence: Moreover hes schoolbag is beautiful.
correct_sentence: Moreover, his schoolbag is beautiful.
error: hes
correction: , his
error_type: Pronoun Error
error_severity: 3
error_description: ① Punctuation Error: According to English grammar rules, a comma is needed after 〈Moreover〉 in the original sentence; therefore, 〈Moreover〉 should be changed to 『Moreover,』 to ensure grammatical correctness.; ② Pronoun Error: Based on the sentence meaning, the intention is to express possession ('his'). The word 〈hes〉 in the original sentence is incorrect; the possessive form 『his』 should be used. Therefore, 〈hes〉 is changed to 『his』 to indicate possession and fit the context.
