Error analysis:
error_sentence: I usually get up at 6:30 o'clock.
correct_sentence: I usually get up at 6:30 a.m.

correction: a.m.
error_type: Noun Error
error_severity: 1
error_description: Noun Error: According to English time expression conventions, 〈o'clock〉 is only used for expressing time on the hour, such as 6 o'clock, and cannot be used with AM/PM designations. The redundant 〈o'clock〉 should be deleted; using the number + time abbreviation structure 『6 a.m.』 more accurately represents the morning time and conforms to English time expression norms.

error_sentence: At 7:10 o'clock to eat breakfast and goto school at 7:40 o'clock.
correct_sentence: At 7:10 a.m. I eat breakfast and go to school at 7:40 a.m.
error: o'clock to
correction: a.m. I
error_type: Noun Error
error_severity: 3
error_description: ① Noun Error: According to English time expression conventions, 〈o'clock〉 is only used for expressing time on the hour (e.g., 7 o'clock) and cannot be used with minutes. Time period expressions must use 『a.m./p.m.』 instead of 〈o'clock〉. Therefore, 〈7:10 o'clock〉 is corrected to the standard time format 『7:10 a.m.』; ② Sentence Structure Error: The original sentence lacks a subject; based on the context, the subject 『I』 is added to form a complete subject-verb structure, making the sentence complete.

error_sentence: At 7:10 o'clock to eat breakfast and goto school at 7:40 o'clock.
correct_sentence: I eat breakfast and go to school at 7:40 a.m.
error: goto
correction: go to
error_type: Space Error
error_severity: 1
error_description: Space Error: According to English phrase construction rules, 〈goto〉 does not conform to the standard expression for 'go somewhere'. The merged spelling 〈goto〉 should be split into two separate words 『go to』, where 『go』 is the verb and 『to』 is the preposition, forming a verb phrase indicating direction.

error_sentence: At 7:10 o'clock to eat breakfast and goto school at 7:40 o'clock.
correct_sentence: I eat breakfast and go to school at 7:40 a.m.
error: o'clock.
correction: a.m.

The redundant 〈o'clock〉 should be deleted; using the number + time abbreviation structure 『7:40 a.m.』 more accurately represents the morning time and conforms to English time expression norms.

error_sentence: At 12 o'clock I usually eat lunch in school.
correct_sentence: At 12 o'clock I usually eat lunch at school.
error: in
correction: at
error_type: Preposition Error
error_severity: 2
error_description: Preposition Error: Based on the semantic difference in English collocations, 『at school』 emphasizes a specific location within the school grounds (like a place for meals), whereas 〈in school〉 focuses on the abstract state of 'being in education'. The context here requires specifying the physical place where lunch occurs, so 〈in〉 is corrected to the more precise preposition 『at』, resulting in the phrase 『at school』 to comply with the usage norms for adverbials of place.

error_sentence: And at 2 o'clock we have three classes to 5 o'clock.
correct_sentence: And from 2:00 p.m. we have three classes until 5:00 p.m. At 5:50 p.m.
error: at 2 o'clock
correction: from 2:00 p.m.
error_type: Noun Error
error_severity: 3
error_description: ① Preposition Error: According to English time expression conventions, 〈at〉 is used for specific points in time, while the starting point of a time range should use the starting preposition 『from』. ② Noun Error: English time expressions require clear period indicators, so 『p.m.』 is added after 〈2:00〉 to eliminate ambiguity; also, 〈o'clock〉 cannot appear with 『p.m.』. It is finally corrected to 『from 2:00 p.m.』, fully meeting the grammatical and semantic requirements for 'afternoon class start time'.

error_sentence: And at 2 o'clock we have three classes to 5 o'clock.
correct_sentence: And from 2:00 p.m. we have three classes until 5:00 p.m. At 5:50 p.m.
error: to 5 o'clock.
correction: until 5:00 p.m.
error_type: Noun Error
error_severity: 3
error_description: ① Preposition Error: According to the rules for expressing duration in English, 〈to〉 is mainly used for movement or range between two points, while the endpoint of a time continuation should use the duration preposition 『until』. Corrected to 『until 5:00』; ② Noun Error: English time expressions require clear period indicators, so 『p.m.』 is added after 〈5:00〉 to eliminate ambiguity; also, 〈o'clock〉 cannot appear with 『p.m.』. It is finally corrected to 『until 5:00 p.m.』, fully meeting the grammatical and semantic requirements for 'afternoon class end time'.

error_sentence: At 5:50 o'clock I am eat dinner And go to bed at 9:30 o'clock.
correct_sentence: And from 2:00 p.m. we have three classes until 5:00 p.m. At 5:50 p.m. I eat dinner and go to bed at 9:30 p.m.
error: o'clock I am
correction: p.m. I
error_type: Word Redundancy Error
error_severity: 3
error_description: ① Noun Error: According to English time writing conventions, 〈o'clock〉 is only used for expressing time on the hour (e.g., 5 o'clock), while times including minutes require the format of number plus period indicator. Therefore, 〈5:50 o'clock〉 is corrected to the standardized time format 『5:50 p.m.』, where 『p.m.』 clearly indicates the afternoon period, conforming to English time expression conventions; ② Word Redundancy Error: According to English grammar rules, 〈am eat〉 incorrectly mixes a linking verb and a base verb form. When expressing habitual actions, the simple present tense should be used, so the redundant linking verb 〈am〉 is deleted, retaining the base verb 『eat』 to form the grammatically correct subject-verb structure 『I eat』, accurately expressing the routine action 'I eat (dinner)'.

error_sentence: At 5:50 o'clock I am eat dinner And go to bed at 9:30 o'clock.
correct_sentence: I eat dinner and go to bed at 9:30 p.m.
error: And
correction: and
error_type: Case Error
error_severity: 1
error_description: Case Error: According to English conjunction writing conventions, the conjunction 〈And〉, when used mid-sentence and not at the beginning or as part of a proper noun, should remain in lowercase. Therefore, the unnecessarily capitalized 〈And〉 in the sentence is corrected to the lowercase conjunction 『and』 to comply with standard English grammar rules regarding conjunction capitalization.

error_sentence: At 5:50 o'clock I am eat dinner And go to bed at 9:30 o'clock.
correct_sentence: I eat dinner and go to bed at 9:30 p.m.
error: o'clock.
correction: p.m.
