Error analysis:
error_sentence: I made some plans at the next weekend.
correct_sentence: I have made some plans for next weekend.
error: at the
correction: for
error_type: Preposition Error
error_severity: 3
error_description: ① Preposition Error: According to English time expression norms, 〈at〉 is typically used for specific time points, whereas the context here requires expressing time arrangements or plans, and "plan+for" is a fixed phrase; therefore, 〈at〉 should be changed to 『for』 to fit the correct collocation logic for the time adverbial; ② Determiner Error: In English, time phrases (like next weekend, next week, next year) usually do not require the definite article 'the' because they inherently have a specific reference (pointing to the "upcoming weekend"); thus, the correct form is 『for next weekend』.

error_sentence: I am going to watch TV at 11:00 in the moring to relax.
correct_sentence: I am going to watch TV at 11:00 in the morning to relax.
error: moring
correction: morning
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: According to English spelling rules, the intention here is to express the concept of "morning"; 〈moring〉 does not conform to the correct spelling and should be corrected to 『morning』 to meet standard writing conventions.

error_sentence: This is my plans of the whole weekend.
correct_sentence: This is my plan for the whole weekend.
error: plans of
correction: plan for
error_type: Noun Number Error
error_severity: 3
error_description: ① Noun Number Error: According to English grammar rules, the subject 〈This〉 is third-person singular, and the verb requires the singular form 〈is〉; therefore, the predicative noun must also be singular. The plural form 〈plans〉 of the noun "plan" should be changed to the singular form 『plan』 to comply with grammatical principles; ② Preposition Error: According to fixed English expressions, 〈of〉 typically indicates possession or material relationship, whereas the context here requires 〈for〉 to indicate the object to which the plan applies; therefore, 〈of〉 should be changed to 『for』 to correctly connect the time scope adverbial.
