error_type: Conjunction Error
error_severity: 2
error_description: Conjunction Error: According to English grammar rules, the necessary conjunction is missing between the two independent clauses 〈The weekend is coming〉 and 〈what are you going to do?〉. The coordinating conjunction 『and』 should be added after the comma to correctly connect the two clauses, making the sentence conform to the standard structure of an English compound sentence.

error_type: Subject-Verb Agreement Error
error_severity: 2
error_description: Subject-Verb Agreement Error: According to English grammar rules, when the collective noun 〈my family〉 refers to the group as a whole, the verb should be in the singular form. The original sentence uses the plural verb 〈are〉, so it needs to be changed to the singular verb 『is』 to maintain subject-verb agreement.

correct_sentence: In the afternoon, my family is going to the park to fly kites.

error_type: Determiner Error
error_severity: 2
error_description: Determiner Error: According to English grammar rules, the use of the definite article 〈the〉 in 〈fly the kites〉 is incorrect because 〈kites〉 here refers to the general category of "kites" rather than specific ones. Following English article usage rules, the determiner 〈the〉 should be deleted, changing the phrase to 『fly kites』 to meet the requirement for generic reference.

error_severity: 1
error_description: Case Error: According to English writing conventions, the pronoun 〈we〉 at the beginning of the sentence requires capitalization. Therefore, the lowercase pronoun 〈we〉 is changed to the capitalized pronoun 『We』 to comply with the rule for sentence-initial capitalization.
