error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English grammar rules, two independent clauses 〈the boy is handsome〉 and 〈he is my friend〉 cannot be joined solely by a comma, as this creates a comma splice error. Therefore, the comma 〈,〉 should be changed to a period 『.』 to correctly separate the two independent sentences.

error_sentence: He wears a pure white shirtand a pair of blue shoes, they are beautiful, He very likes blue, but I can't like.
correct_sentence: He wears a pure white shirt and a pair of blue shoes.
error: shirtand
correction: shirt and
error_type: Space Error
error_severity: 2
error_description: Space Error: According to English writing conventions, 〈shirtand〉 should be two separate words, requiring a space between them. The original sentence incorrectly merges them into 〈shirtand〉, violating English orthographic rules. Therefore, a space needs to be added between 〈shirt〉 and 〈and〉, correcting it to 『shirt and』 to ensure correct spelling.

error_sentence: He wears a pure white shirtand a pair of blue shoes, they are beautiful, He very likes blue, but I can't like.
correct_sentence: He wears a pure white shirt and a pair of blue shoes. They are beautiful.
error: , they
correction: . They
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English grammar rules, joining the two independent clauses 〈He wears a pure white shirtand a pair of blue shoes〉 and 〈they are beautiful〉 with only a comma constitutes a grammatical error. Therefore, the connecting comma 〈,〉 needs to be changed to a period 『.』 to correctly separate the two complete sentences.

error_sentence: He wears a pure white shirtand a pair of blue shoes, they are beautiful, He very likes blue, but I can't like.
correct_sentence: They are beautiful. He likes blue very much, but I don't.
error: , He very likes blue
correction: . He likes blue very much
error_type: Word Order Error
error_severity: 2
error_description: ① Punctuation Error: According to English grammar rules, the independent clause 〈He very likes blue〉 creates a run-on sentence with the preceding clause and must be separated by a period. Therefore, the connecting comma 〈,〉 is changed to a period 『.』 to ensure complete sentence structures; ② Adverb Error: According to English adverb usage rules, the intensifier 〈very〉 cannot directly modify the verb 〈likes〉; it should be combined with 'much' to form the fixed phrase 『very much』; ③ Word Order Error: The position of the adverb 〈very〉 is unconventional in English; it should follow 〈likes〉. Therefore, 〈very〉 is changed to 『very much』 and placed after the verb phrase 〈likes blue〉. The word order is adjusted to 『likes blue very much』 to conform to standard English usage.

error_sentence: He wears a pure white shirtand a pair of blue shoes, they are beautiful, He very likes blue, but I can't like.
correct_sentence: He likes blue very much, but I don't.
error: can't like
correction: don't
error_type: Auxiliary Error
error_severity: 2
error_description: Auxiliary Error: According to English expression conventions, 〈can't like〉 is an incorrect modal verb combination. The modal verb 〈can't〉 expresses the negation of ability or possibility, whereas the intended meaning here is the negation of subjective preference. Therefore, the auxiliary verb 『don't』 should be used to form the negative in the simple present tense.
