error_type: Spelling Error
error_severity: 1

correction: have
error_type: Verb Tense Error
error_severity: 3
error_description: Verb Tense Error: Judging from the sentence's meaning, the present perfect tense is required here; the auxiliary verb 〈have〉 is needed to indicate the decision's current impact, so 『have』 should be added before 〈decided〉 to form 『have decided』.
error_sentence: So I decided to do some meaningful action the summer holiday.
correct_sentence: So I have decided to do some meaningful activities during the summer holiday.
error: action
correction: activities during

error_description: ① Verb Choice Error: Judging from the sentence's meaning, the intention here is to express “take courses”; the verb 『take』 should be used instead of 〈do〉. ② Noun Number Error: The quantifier 〈some〉 is used before 〈tutorial〉, so it needs to be changed to the plural form 『tutorials』.
