Error analysis:
error_sentence: I'm ten-year-old.
correct_sentence: I'm ten years old.
error: -year-
correction: years
error_type: Adjective Error
error_severity: 2
error_description: Adjective Error: According to English age expression rules, the compound adjective 〈ten-year-old〉 can only be used as a pre-modifier; in a predicative structure, 『ten years old』 should be used as the predicate to express age. Therefore, the incorrect compound adjective structure is corrected to the grammatically correct age expression 『ten years old』 to form a complete and correct predicative sentence.
error_sentence: That hand some man is my father John.
correct_sentence: That handsome man is my father John.
error: hand some
correction: handsome
error_type: Space Error
error_severity: 1
error_description: Space Error: According to adjective spelling rules, the adjective 〈handsome〉 was incorrectly split into two words 〈hand〉 and 〈some〉; the space in between needs to be removed to correctly spell it as 『handsome』 meaning 'good-looking'.
error_sentence: He is 45 year old.
correct_sentence: He is 45 years old.
error: year
correction: years
error_type: Noun Number Error
error_severity: 2
error_description: Noun Number Error: According to the rules for matching countable nouns with numbers in English, when the cardinal number is greater than 1, the following countable noun 〈year〉 must be in the plural form. Therefore, the singular noun 〈year〉 needs to be changed to the plural form 『years』, so that the phrase 『45 years』 conforms to the 'number + plural noun' grammatical standard.
error_sentence: She is an English teacher in my school and that boy is my brother paul.
correct_sentence: She is an English teacher in my school and that boy is my brother Paul.
error: paul
correction: Paul
error_type: Case Error
error_severity: 1
error_description: Case Error: According to English rules for spelling proper names, the proper noun 〈paul〉 needs to be capitalized to conform to English standards. Therefore, the incorrect noun 〈paul〉 is modified to 『Paul』 to comply with the correct name spelling rules.
error_sentence: He like play football very much.
correct_sentence: He likes to play football very much.
error: like
correction: likes to
error_type: Nonfinite Verb Form Error
error_severity: 4
error_description: ① Subject-Verb Agreement Error: According to English third-person singular rules, when the subject is the singular pronoun 〈He〉, the predicate verb needs to be in the singular form. The original verb 〈like〉 lacks the third-person singular inflection, so the ending 〈-s〉 needs to be added, correcting it to 『likes』 to maintain subject-verb agreement; ② Nonfinite Verb Form Error: According to English infinitive structure rules, the verb 〈play〉 in the context of expressing 'like to do something' needs to be paired with the infinitive marker 'to'. Therefore, 『to』 needs to be added before 〈play〉 to form the complete infinitive structure 『to play』, ultimately correcting the whole phrase to 『likes to play』 to conform to standard English collocation.
error_sentence: It is me
correct_sentence: It is me.
correction: .
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English sentence structure rules, a declarative sentence must end with a terminal punctuation mark. The original sentence is missing the end punctuation after the pronoun 〈me〉; a period 『.』 needs to be added to form a complete syntactic structure, modifying it to 『me.』 to comply with English writing conventions.
