Error analysis:
error_sentence: I'mEmily.
correct_sentence: I'm Emily.
error: I'mEmily
correction: I'm Emily
error_type: Space Error
error_severity: 1
error_description: Space Error: According to English writing conventions, there should be a space between the contraction 〈I'm〉 and the name 〈Emily〉. The original sentence's 〈I'mEmily〉 lacks separation, which is non-standard. A space should be added between 〈I'm〉 and 〈Emily〉, changing 〈I'mEmily〉 to 『I'm Emily』 to ensure clarity and adherence to English writing requirements.

error_sentence: I'm ten year old.
correct_sentence: I'm ten years old.
error: year
correction: years
error_type: Noun Number Error
error_severity: 3
error_description: Noun Number Error: According to English grammar rules, when a number is greater than one, the following countable noun must be in plural form. In the original sentence, the number 〈ten〉 means 'ten', which is greater than one, so the following countable noun 〈year〉 should be in plural form. 〈year〉 needs to be changed to 『years』 to make the sentence conform to the grammatical rules for noun plurals.

error_sentence: The boy is my borther, Paul.
correct_sentence: The boy is my brother, Paul.
error: borther
correction: brother
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: Based on the sentence meaning, the original sentence intends to express 'This boy is my brother, Paul', but 〈borther〉 is misspelled. The correct spelling should be 『brother』. 〈borther〉 needs to be changed to 『brother』 to ensure correct spelling, clear expression, and adherence to English spelling rules.

error_sentence: Last, the girk ia me.
correct_sentence: Lastly, the girl is me.
error: Last
correction: Lastly
error_type: Adverb Error
error_severity: 3
error_description: Adverb Error: According to English grammar rules, the adverb 〈lastly〉 should be used when indicating the final item in a list. The original sentence uses the adjective 〈Last〉, which cannot accurately express the logical sequence of the sentence. 〈Last〉 should be changed to 『Lastly』 to conform to the grammatical usage of adverbs and correctly convey the logical relationship of 'finally'.

error_sentence: Last, the girk ia me.
correct_sentence: Lastly, the girl is me.
error: girk ia
correction: girl is
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: Based on the sentence meaning, the intention here is to express 'the girl is me', but 〈girk〉 is a misspelling of 〈girl〉. To ensure correct expression, 〈girk〉 needs to be changed to 『girl』, meaning 'girl'; 〈ia〉 is a misspelling of 〈is〉. 〈is〉 serves as the sentence's predicate verb, and the original spelling makes the sentence semantically and grammatically incorrect. 〈ia〉 should be changed to 『is』 to make the sentence semantically clear and grammatically correct.
