error_type: Conjunction Error
error_severity: 5
error_description: ① Spelling Error: Based on the context, the intended name is "峰", so 〈Fong〉 is a misspelling of 『Feng』; it needs to be changed to 『Feng』 for the sentence to make sense; ② Conjunction Error: 〈I'm Gao Feng〉 and 〈I like football〉 both contain subject-verb structures and can stand alone as sentences; therefore, the conjunction 『and』 should be added before 〈I like football〉 to form a compound sentence; ③ Spelling Error: According to the original sentence, 〈l'm Gao Fong,〉 is meant to express "I am Gao Feng", so the pronoun should be the first person and capitalized as 『I』; thus, 〈l〉 in the original sentence is a spelling error and needs to be changed to 『I』.

error_sentence: One name is Mike and one name is Dave.
correct_sentence: One's name is Mike and the other's name is Dave.
correction: 's
error_type: Noun Possessive Error
error_severity: 3
error_description: Noun Possessive Error: According to English possessive grammar rules, 〈One〉 as a determiner needs the possessive form 『's』 added to form 『One's』, indicating the possessive relationship of 'someone's name'.

error_sentence: One name is Mike and one name is Dave.
correct_sentence: One's name is Mike and the other's name is Dave.
error: one
correction: the other's
error_type: Pronoun Error
error_severity: 3
error_description: ① Pronoun Error: According to English grammar rules, when referring to two objects in a parallel structure, the fixed phrase "one... and the other..." should be used. The original sentence uses 〈one〉 twice; the second repeated 〈one〉 should be changed to 『the other』 to avoid logical confusion; ② Noun Possessive Error: The sentence means "the other person's name is Dave", indicating a possessive relationship between the name and the other person, so the noun possessive form is needed, corrected to 『the other's』.

error_sentence: Mike likes basketball, he doesn't like ping-pong.
correct_sentence: Mike likes basketball. He doesn't like ping-pong.
error: , he
correction: . He
error_type: Punctuation Error
error_severity: 3
error_description: ① Punctuation Error: 〈Mike likes basketball〉 and 〈he doesn't like ping-pong〉 both contain independent subject-verb structures and can stand alone as sentences; therefore, a period, not a comma, should be used to separate the two sentences; ② Case Error: According to English writing conventions, 〈he〉 at the beginning of a sentence should have its first letter capitalized, changed to 『He』.

error_sentence: Dave likes soccer, he doesn't baseball.
correct_sentence: Dave likes soccer. He doesn't like baseball.
error: , he
correction: . He

error_type: Sentence Structure Error
error_severity: 3
error_description: Sentence Structure Error: According to English grammar rules, the negative structure "doesn't ..." requires a main verb. The absence of the predicate verb here constitutes a sentence structure error. Based on the intended meaning, the missing predicate verb 『like』 needs to be added after 〈doesn't〉 to form a complete negative sentence.
