error_type: Nonfinite Verb Form Error
error_severity: 4
error_description: ① Nonfinite Verb Form Error: According to the rules of the English present continuous tense, the structure requires 'be verb + present participle'. The original sentence uses the base form 〈buy〉, which is grammatically incorrect; it must be changed to the present participle form 『buying』 to form the complete structure 『is buying』 to correctly express the ongoing action; ② Spelling Error: Based on contextual semantic analysis, 〈foot〉 (part of the body/unit of length) clearly does not fit the eating context; it is a spelling error for 『food』. The incorrect noun 〈foot〉 needs to be replaced with the target noun 『food』.

error_sentence: A youny lady is looking at a dress , maybe she likes it .
correct_sentence: A young lady is looking at a dress, and maybe she likes it.
error: youny
correction: young
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: According to the correct spelling rules for English adjectives, 〈youny〉 does not match any valid word form; it is a spelling error for the adjective 『young』. It needs to be replaced with the correct spelling 『young』 to express the meaning "young".

error_sentence: A youny lady is looking at a dress , maybe she likes it .
correct_sentence: A young lady is looking at a dress, and maybe she likes it.
correction: and
error_type: Conjunction Error
error_severity: 3
error_description: Conjunction Error: According to the rules of English compound sentence structure, the two independent clauses 〈maybe she likes it〉 and 〈A young lady is looking at a dress〉 lack a logical connector, leading to a semantic break. The coordinating conjunction 『and』 needs to be added between the two clauses to clarify the parallel relationship between them.

error_sentence: Linda's mother is try the shoes and Linda's father is wait for her stay 0nthe sofa .
correct_sentence: Linda's mother is trying on the shoes and Linda's father is waiting for her on the sofa.
error: try
correction: trying on
error_type: Nonfinite Verb Form Error
error_severity: 4
error_description: ① Nonfinite Verb Form Error: According to the grammatical rules of the English present continuous tense, the structure requires 'be verb + present participle'. The original sentence uses the base form 〈try〉, which is grammatically incorrect; it must be changed to the present participle form 『trying』 to form the complete structure 『is trying』 to correctly express the ongoing action; ② Preposition Error: According to the rules of English phrasal verb collocations and the prompt requirements, 〈try on〉 is the standard phrasal verb for "to test clothing". The original sentence lacks the necessary preposition 『on』, resulting in incomplete meaning; 『on』 needs to be added to specify the object of the action (clothing).

error_sentence: Linda's mother is try the shoes and Linda's father is wait for her stay 0nthe sofa .
correct_sentence: Linda's mother is trying on the shoes and Linda's father is waiting for her on the sofa.

error_type: Word Redundancy Error
error_severity: 5
error_description: ① Word Redundancy Error: Based on sentence meaning analysis, the verb 〈stay〉 conflicts semantically with the main predicate 『is waiting』 and does not form any valid grammatical structure. Deleting the redundant word 〈stay〉 makes the core meaning "Linda's father is waiting for her on the sofa" clearer while maintaining the integrity of the adverbial of place; ② Spelling Error: The misuse of the digit 〈0〉 for the letter 〈o〉 is a common input error; 〈0nthe〉 needs to be corrected to the proper form 『on the』 to express the meaning "on the sofa"; ③ Space Error: According to English writing conventions, the preposition 『on』 and the article 『the』 must be written as two separate words. A space needs to be added between them to correctly express 『on the』 and avoid the incorrect joined form 〈0nthe〉.
