The original sentence 〈Nov.25〉 lacks a space, which does not conform to conventions; 〈Nov.25〉 should be changed to 『Nov. 25』.; ② Space Error: Similarly, based on English date writing requirements, the necessary space between the month abbreviation and the day number is missing, leading to incorrect formatting; 〈Nov.25〉 needs to be changed to 『Nov. 25』 to conform to standard writing format.

error_description: Spelling Error: According to English fixed collocation rules, 'not only... but also...' is a common correlative conjunction used to connect parallel elements, meaning 'not only... but also...'.

error_type: Noun Number Error
error_severity: 3
error_description: Noun Number Error: According to English grammar rules, 〈advice〉 is an uncountable noun and cannot be made plural by adding 〈-s〉. The use of 〈advices〉 in the original sentence is a misuse of noun number; it should be changed to the singular form 『advice』 to comply with grammatical rules.

error_type: Verb Tense Error
error_severity: 3
error_description: Verb Tense Error: According to English grammar rules, the past tense of the verb 〈deal〉 is an irregular change, and the correct form is 〈dealt〉. The original sentence uses the non-standard past tense form 〈dealed〉, which does not conform to English verb tense rules and standard expression; 〈dealed〉 should be changed to 『dealt』 to ensure correct tense expression in the sentence.
