error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English time expression conventions, the Latin abbreviation 〈pm〉 must use periods to separate the letters to conform to standard format; therefore, 〈pm〉 is modified to 『p.m.』 with periods to ensure correct formatting.

error_sentence: Look, there is a little girl; she is buying some food she likes.
correct_sentence: Look, there is a little girl. She is buying some food she likes.
error: ; she
correction: . She
error_type: Punctuation Error
error_severity: 3
error_description: ① Punctuation Error: According to English punctuation rules, the semicolon 〈;〉 is only used to connect grammatically independent but closely related clauses. In the current context, the two sentences are semantically complete and independent, so the semicolon in 〈a little girl; she〉 is changed to a period 『a little girl. She』 for correct sentence separation; ② Case Error: Based on basic English writing rules, the first letter of a sentence must be capitalized. Therefore, the sentence-initial pronoun 〈she〉 is corrected to the capitalized 『She』 to ensure compliance with English capitalization rules.

error_sentence: And you can see a young lady is looking at a dress that suitable for her.
correct_sentence: And you can see a young lady looking at a dress that is suitable for her.
error: is
error_type: Nonfinite Verb Form Error
error_severity: 3
error_description: Nonfinite Verb Form Error: According to English object complement rules, when the perception verb 〈see〉 is followed by the object 〈a young lady〉, the present participle 〈looking〉 should be used to indicate 'seeing someone performing an action', forming the fixed structure 'see sb. doing'. The original sentence mistakenly uses the finite verb form 〈is looking〉; the auxiliary verb 〈is〉 needs to be deleted, correcting it to 『see a young lady looking...』 to comply with grammatical rules.

error_sentence: And you can see a young lady is looking at a dress that suitable for her.
correct_sentence: And you can see a young lady looking at a dress that is suitable for her.
correction: is
error_type: Verb Choice Error
error_severity: 3
error_description: Verb Choice Error: According to English relative clause construction rules, when the relative pronoun 〈that〉 refers to the singular noun 〈dress〉, the clause must contain a complete predicate structure. The original sentence lacks a linking verb, so 『is』 is added to form 『that is suitable for her』, satisfying both subject-verb agreement (third-person singular) and the fixed phrase 'be suitable for'.

error_sentence: My mother is trying the shoes.
correct_sentence: My mother is trying on the shoes.
correction: on
error_type: Preposition Error
error_severity: 2
error_description: Preposition Error: Based on English phrasal collocations and the sentence's meaning, 'try on' is an inseparable phrasal verb; the preposition 『on』 must be retained to fully express the meaning of 'trying on clothes'. Therefore, the missing preposition 『on』 is added to form the correct phrase 『trying on』 for more precise expression.

error_sentence: Tt's a busy but fun day.
correct_sentence: It's a busy but fun day.
error: Tt
correction: It
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: Letter checking confirms that the sentence-initial 〈Tt〉 is a spelling mistake. According to English pronoun writing standards, the misspelling is corrected to the singular pronoun 『It』, meaning 'it', while ensuring the first letter is capitalized to comply with sentence-initial writing conventions.
