error_type: Word Redundancy Error
error_severity: 3
error_description: Word Redundancy Error: According to English grammar rules, only one determiner can modify a single noun phrase. In the original sentence, both 〈a〉 and 〈my〉 appear before 〈best friend〉, violating the single determiner rule. Based on the intended meaning of expressing the general concept of 'a best friend', the possessive pronoun 『my』 is deleted while retaining the indefinite article 〈a〉, changing it to [a best friend] to comply with English determiner usage norms.

error_sentence: I have a my best friend is Mike.
correct_sentence: I have a best friend. He is Mike.
correction: . He
error_type: Sentence Structure Error
error_severity: 2
error_description: Sentence Structure Error: According to English grammar rules, the original sentence 〈I have a best friend is Mike〉 contains two complete clauses without proper connection. Based on the intended meaning to convey two separate pieces of information, 'having a best friend' and 'the friend's identity', a period should be added after 〈friend〉 and the subject 『He』 should be supplied, rewriting it as 『I have a best friend. He is Mike』. This maintains semantic integrity and adheres to the basic structural requirement that English sentences must contain a subject and a predicate.

error_sentence: He looks like very beautiful.
correct_sentence: He looks very beautiful.
error: like
error_type: Word Redundancy Error
error_severity: 3
error_description: Word Redundancy Error: According to English grammar rules, when the linking verb 〈looks〉 functions as a sensory verb, it should be directly followed by an adjective as a predicative, forming the basic sentence structure 'subject + linking verb + adjective'. The preposition 〈like〉 added in the original sentence is redundant because 〈like〉 is typically used to introduce nominal elements. Based on the intended meaning to express the adjective description 'looks very beautiful', the preposition 〈like〉 should be deleted, changing it to 『looks very beautiful』 to comply with the correct usage of a linking verb followed by an adjective complement.

error_sentence: I like his wear.
correct_sentence: I like his clothes.
error: wear
correction: clothes
error_type: Noun Error
error_severity: 3
error_description: Noun Error: According to English vocabulary usage norms, the noun 〈wear〉 usually refers to 'manner of dressing' or 'state of being worn', whereas the context of this sentence requires expressing fondness for clothing in general. Based on the intended meaning, the more accurate noun 『clothes』 (referring to all garments) should be used. Therefore, 〈wear〉 is replaced with 『clothes』 to conform to the idiomatic usage of nouns related to clothing, while preserving the original sentence's emotional intensity and ensuring semantic integrity and lexical accuracy.
