error_severity: 3
error_description: ① Noun Error: According to English expression conventions, a time indicator is needed after a specific time to clarify AM/PM, so 『a.m.』 should be added after the time point 〈7:40〉 to clearly indicate "7:40 in the morning" to conform to English expression habits.; ② Punctuation Error: According to English writing conventions, when the time indicators "a.m." or "p.m." are at the end of a declarative sentence, no additional period is needed at the end of the sentence to avoid punctuation redundancy; the extra 〈.〉 at the end of the original sentence needs to be deleted to conform to English writing conventions.

error_type: Sentence Structure Error
error_severity: 4
error_description: ① Noun Error: According to English expression conventions, a time indicator is needed after a specific time to clarify AM/PM, so 『a.m.』 should be added after the time point 〈8:30〉 to clearly indicate "8:30 in the morning" to conform to English expression habits.; ② Sentence Structure Error: According to the original sentence's meaning, the intention is to express "continue...until 9:45 in the morning", therefore 『and continue』 needs to be added before "until" to mean "start reading English texts at 8:30 in the morning and continue until" to make the sentence structure complete and conform to the original meaning.

error_type: Space Error
error_severity: 1
error_description: Space Error: According to English word spelling conventions, the compound noun "daytime" means "daytime; during the day", therefore there is a space error here. The space between 〈day time〉 needs to be deleted and changed to the joined form 『daytime』 to conform to English word spelling conventions and the original sentence meaning.

error_sentence: Sometimes I take exercise, sometimes I clean house and sometimes I cook dinner.
correct_sentence: Sometimes I take exercise, sometimes I clean the house, and sometimes I cook dinner.
error: house
correction: the house,
error_type: Determiner Error
error_severity: 3
error_description: ① Determiner Error: According to English grammar rules, the singular countable noun 〈house〉 lacks an article for limitation; the definite article 『the』 needs to be added to specifically refer to "the house" to conform to English grammar rules.; ② Punctuation Error: According to English syntax rules, when there are three or more parallel clauses, a comma and the coordinating conjunction "and" are needed between the last two clauses; therefore, a 『,』 needs to be added before 〈and sometimes I cook dinner〉 here to conform to English syntax rules.

error_sentence: My holiday is so busy but I'm happy.
correct_sentence: My holiday is so busy, but I'm happy.
correction: ,
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English syntax rules, a comma is needed before the adversative conjunction "but" in a compound sentence to separate clauses and avoid run-on elements. Therefore, there is a punctuation error here. 〈 busy but〉 needs to be changed to 『busy, but』 to conform to English syntax rules.
