error_description: Determiner Error: According to English collocation rules, articles are usually not used when referring to the names of sports (such as football, basketball, etc.). Therefore, the definite article 〈the〉 is deleted, correcting 〈play the football〉 to 『play football』 to conform to standard English expression. This rule also applies to other similar sports.

correct_sentence: I think it is going to be a happy day.
error: happy on that
correction: a happy
error_type: Determiner Error
error_severity: 2
error_description: ① Determiner Error: The subject 〈it〉 referring to “that day” should not be modified by 〈happy〉; according to English expression habits, it is recommended to change it to 『happy day』. When 〈happy〉 as an adjective modifies the countable singular noun 〈day〉, the indefinite article 〈a〉 needs to be added to form the structure 『a happy day』, conforming to the correct pattern "indefinite article + adjective + noun"; ② Word Redundancy Error: According to English expression habits, the phrase 〈on that〉 is not needed before 〈a happy day〉; therefore, the redundant words 〈on that〉 are deleted, simplifying 〈on that day〉 to 『day』 to better align with the idiomatic structure of English time adverbials.
