error_type: Sentence Structure Error
error_severity: 5
error_description: ① Sentence Structure Error: According to English grammar rules, when 〈After〉 is used as a conjunction to introduce an adverbial clause of time, it lacks an object here. Therefore, the object 『that』 is added after 〈After〉 to complete the sentence structure; ② Punctuation Error: According to English expression habits, when an adverbial of time acts as an independent element at the beginning of a sentence, it needs to be separated from the main clause by a comma. Therefore, a 『,』 is added after 『After that』 to comply with English punctuation norms.

correct_sentence: After that, I went to the park to play with my friends.
correction: to
error_type: Nonfinite Verb Form Error
error_severity: 3
error_description: Nonfinite Verb Form Error: According to English grammar rules, an infinitive structure is required to express purpose. In the original sentence, 〈play〉 needs to be in the 'to + base form of verb' infinitive form to comply with grammar rules. Therefore, 『to』 is added before 〈play〉 to correctly express the intention.

correct_sentence: I like to play basketball, so I played basketball during the weekend.

error_type: Nonfinite Verb Form Error

correction: played basketball during the weekend
error_type: Word Redundancy Error
error_severity: 5
error_description: ① Word Redundancy Error: According to English expression habits, 〈play〉 in the original sentence already clearly expresses the action, making 〈caugh〉 a redundant word here. Deleting it does not affect the sentence meaning, so 〈caugh〉 is deleted; ② Verb Tense Error: According to the prompt requirements, the action occurred in the past and should use the simple past tense. Therefore, 〈play〉 is changed to 『played』; ③ Preposition Error: According to English expression habits, the meaning here is 'during...', and the time expression 〈on week〉 in the original sentence is inaccurate. It should be changed to 『during the weekend』 to conform to English expression habits.

correct_sentence: I cleaned the room with my family in the afternoon.

error_type: Punctuation Error
error_severity: 4
error_description: ① Punctuation Error: According to English expression habits, the time adverbial 〈in the evening〉 in the original sentence, as an independent element, needs to be separated from the main clause by a comma. Therefore, a 『,』 is added after 〈in the evening〉 to comply with English punctuation norms; ② Spelling Error: According to English writing conventions, the spelling 〈watch ed〉 in the original sentence is incorrect. It is changed to the past tense form 『watched』 to conform to spelling conventions.

error_sentence: I had a fun on week.
correct_sentence: I had fun that week.
error: a fun on
correction: fun that
error_type: Preposition Error
error_severity: 4
error_description: ① Determiner Error: According to English grammar rules, an article is not needed before an uncountable noun. In the original sentence, 〈fun〉 is an uncountable noun, so the redundant article 『a』 is deleted to comply with English grammar; ② Preposition Error: According to the context, the meaning here is 'that week'. The time expression 〈on week〉 in the original sentence is inaccurate and should be changed to 『that week』 to fit the context.
