error_type: Sentence Structure Error
error_severity: 3
error_description: Sentence Structure Error: According to basic English sentence patterns, the original sentence lacks a linking verb; 〈is〉 should be added, with 〈Monday〉 serving as the predicative, to form a complete subject-linking verb-predicative structure.

error_sentence: Then, I'm brush my tooth.
correct_sentence: Then, I brush my teeth.
error: 'm
error_type: Auxiliary Error
error_severity: 3
error_description: Auxiliary Error: According to English grammar rules, 〈I'm brush〉 incorrectly uses the present continuous structure 『am doing』. Based on the meaning (expressing a daily habitual action), the simple present tense should be used. Therefore, the auxiliary verb 〈'm〉 is deleted, correcting the structure 〈I'm brush〉 to the simple present structure 『I brush』 for tense consistency.

error_sentence: Then, I'm brush my tooth.
correct_sentence: Then, I brush my teeth.
error: tooth
correction: teeth
error_type: Noun Number Error
error_severity: 2
error_description: Noun Number Error: According to English grammar rules and contextual analysis, 〈tooth〉 is singular, but the context typically refers to multiple teeth (e.g., brushing teeth, dental care). Therefore, the plural form is required. The singular noun 〈tooth〉 is corrected to the plural noun 『teeth』 to ensure semantic accuracy and grammatical correctness.

error_sentence: Next I go to school.
correct_sentence: Next, I go to school.
correction: ,
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English writing conventions, when the time adverb 〈Next〉 starts a sentence, a comma should follow it to separate the adverbial phrase from the main clause. Therefore, the missing comma 『,』 is added after 〈Next〉, correcting the structure to 『Next,』 to ensure compliance with English punctuation rules.

error_sentence: We havs draw class, P.E class and play.
correct_sentence: We have drawing class, P.E. class and we play.
error: havs draw
correction: have drawing
error_type: Adjective Error
error_severity: 3
error_description: ① Spelling Error: According to English writing conventions, 〈havs〉 is not a correct spelling for any English verb. Based on the sentence meaning, the base form 『have』 meaning 'to possess' should be used here; therefore, the misspelling 〈havs〉 is corrected to the proper verb form 『have』; ② Adjective Error: According to English grammar rules, in 〈draw class〉, the base form of the verb cannot directly modify the noun; 〈draw〉 should be changed to the gerund 『drawing』 acting as an adjective to correctly express the concept of a 'drawing class'.

error_sentence: We havs draw class, P.E class and play.
correct_sentence: We have drawing class, P.E. class and we play.
error: P.E
correction: P.E.
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English writing conventions, the abbreviation 〈P.E〉, formed from the initial letters of 'Physical Education', requires a period after each letter to conform to standard abbreviation format. Therefore, the non-standard 〈P.E〉 is corrected to the internationally accepted standard 『P.E.』 to ensure the formality of the academic term.

error_sentence: We havs draw class, P.E class and play.
correct_sentence: We have drawing class, P.E. class and we play.
correction: we
error_type: Pronoun Error
error_severity: 3
error_description: Pronoun Error: According to the principle of parallel structure in English grammar, clauses connected by the coordinating conjunction 〈and〉 must maintain consistent grammatical structure. The second clause lacks a subject, causing structural imbalance; therefore, the subject 『we』 is added, correcting the structure to 『and we play』, ensuring that both clauses have a complete subject-verb structure and comply with the writing conventions for English compound sentences.

error_sentence: At 9 o'clock, I'm go to bed.
correct_sentence: At 9 o'clock, I go to bed.
error: 'm
error_type: Auxiliary Error
error_severity: 3
error_description: Auxiliary Error: According to English grammar rules, 〈'm〉, the contracted form of the verb 'be', forms an ungrammatical structure with the main verb 〈go〉 here. Based on the meaning (expressing a daily routine), the simple present tense structure should be used. Therefore, the redundant auxiliary verb 〈'm〉 is deleted, correcting the erroneous structure 〈I'm go to bed〉 to the grammatically correct 『I go to bed』 to accurately convey the meaning 'I go to bed'.
