error_description: ① Determiner Error: According to the original sentence, expressing 'life is getting better' does not require the determiner 〈the〉 to modify the specific noun 『life』, therefore 〈the〉 needs to be deleted to conform to determiner modification rules; ② PoS Confusion Error: According to the sentence meaning and English part-of-speech collocation rules, the noun form should be used here to express the concept of 'life', therefore the verb 〈live〉 is changed to the noun 『life』 to ensure part-of-speech accuracy; ③ Word Redundancy Error: According to English grammar rules, 〈better〉 itself is already in the comparative form; adding 〈more〉 constitutes a double comparative error, therefore the redundant adverb 〈more〉 is deleted, retaining the correct comparative form 『better』.
