Error analysis:

correction: to play
error_type: Nonfinite Verb Form Error
error_severity: 3
error_description: Nonfinite Verb Form Error: The original sentence uses 〈because I played〉 to express causality, leading to unclear logic; an infinitive 『to play』 is needed here to express purpose, so 〈because I played〉 is changed to 『to play』 to make the sentence logic clearer.
error_sentence: After that, I play basketball with my father.
correct_sentence: After that, I played basketball with my father.
error: play
correction: played
error_type: Verb Tense Error
error_severity: 3
error_description: Verb Tense Error: According to the prompt requirements, the entire text describes Tommy's life last weekend, so the predicate verb should be in the past tense; therefore, 〈play〉 is changed to the past tense form 『played』 to maintain tense consistency.
error_sentence: I was a winner.
correct_sentence: I was the winner.
error: a
correction: the
error_type: Determiner Error
error_severity: 2
error_description: Determiner Error: According to English grammar rules, the indefinite article 〈a〉 indicates a general reference, but the context here specifically refers to the winner of the basketball game; therefore, 〈a〉 is changed to 『the』 to indicate a specific object.
error_sentence: On Sunday, my mother helped me to finished my homework.
correct_sentence: On Sunday, my mother helped me to finish my homework.
error: finished
correction: finish
error_type: Nonfinite Verb Form Error
error_severity: 3
error_description: Nonfinite Verb Form Error: In the structure following the verb 〈help〉 with an infinitive, 〈to〉 is the infinitive marker and should be followed by the base form of the verb; therefore, 〈finished〉 is changed to 『finish』 to conform to the fixed expression “help sb. (to) do”.
error_sentence: As for me, They were busy but fun days!
correct_sentence: As for me, they were busy but fun days!
error: They
correction: they
error_type: Case Error
error_severity: 1
error_description: Case Error: 〈They〉 is not at the beginning of the sentence, so the first letter does not need to be capitalized; therefore, 〈They〉 is changed to 『they』 to conform to writing conventions.
