error_type: Verb Tense Error

correction: to
error_type: Preposition Error
error_severity: 2
error_description: Preposition Error: According to English usage, the preposition 『to』 is used after the verb 〈go〉 to indicate direction or destination, whereas the determiner 〈the〉 in the original sentence cannot be used alone to indicate direction of action, so 〈the〉 needs to be changed to 『to』 to conform to grammatical rules.

error_type: Preposition Error
error_severity: 4
error_description: ① Spelling Error: According to the meaning of the sentence, the intention is to express 'o'clock', so the spelling of 〈o clock〉 is incorrect; the correct spelling is 『o'clock』 to indicate the hour, so 〈o clock〉 needs to be changed to 『o'clock』; ② Preposition Error: 〈In〉 is used for periods of time, but 『At』 should be used before specific points in time, and in English, 〈noon〉 refers to the specific time point of 12 PM, not a period, so 〈In〉 needs to be changed to 『At』; ③ Determiner Error: According to English usage, the fixed phrase 『At noon』 meaning 'twelve o'clock midday' does not require a determiner in the middle, so 〈the〉 needs to be deleted.

error_sentence: In the noon, we have lunch.
correct_sentence: At noon, I have lunch.
error: we
correction: I
error_type: Pronoun Error
error_severity: 3
error_description: Pronoun Error: According to the context, the subject throughout the text is the first-person singular 『I』, whereas the pronoun 〈we〉 here represents the plural, which is inconsistent with the person in the context, so 〈we〉 needs to be changed to 『I』 to maintain subject consistency.

correct_sentence: In the afternoon, I go home.
error: we go to
correction: I go
error_type: Pronoun Error
error_severity: 4
error_description: ① Pronoun Error: According to the context, the subject throughout the text is the first-person singular 『I』, whereas 〈we〉 here represents the plural, which is inconsistent with the person in the context, so 〈we〉 needs to be changed to 『I』 to maintain subject consistency; ② Preposition Error: According to English usage, the 〈to〉 in 〈go to home〉 is redundant because 'home' functions as an adverb of place and does not require a preceding preposition, so the redundant preposition 〈to〉 needs to be deleted to conform to English usage.
