error_type: Conjunction Error
error_severity: 5
error_description: ① Conjunction Error: According to the context, a conjunction is missing between the two independent clauses; a coordinating conjunction 『and』 needs to be added before 〈he like he close〉 to make the sentence structure clear.; ② Subject-Verb Agreement Error: The subject 〈he〉 is third-person singular; based on the principle of subject-verb agreement, the verb 〈like〉 should also be changed to the third-person singular form 『likes』.; ③ Pronoun Error: According to the original sentence structure, the second 〈he〉 in 〈he like he close〉 should be the possessive adjective form of the personal pronoun; therefore, the second 〈he〉 should be changed to 『his』.; ④ Spelling Error: According to the meaning of the sentence, the intended word here is 'clothes'; therefore, 〈close〉 is a misspelling of 『clothes』 and needs to be corrected to 『clothes』 to make the sentence meaningful.
