error_type: Word Redundancy Error
error_severity: 4
error_description: Word Redundancy Error: According to English expression habits, in the original sentence, 〈shopping〉 already clearly expresses the action; 〈going〉 is a redundant word here. Deleting it will not affect the meaning of the sentence, so 〈am going shopping〉 is simplified to 『am shopping』 to improve conciseness.
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: 2
error_description: ① Punctuation Error: According to English grammar rules, the original sentence parts 〈there is a little girl〉 and 〈she is buying some food〉 are complete clauses; a comma 〈,〉 cannot be used to separate two independent sentences, so 〈, she〉 needs to be changed to 『. She』 to comply with English grammar rules; ② Case Error: According to English written expression norms, the first letter of a word at the beginning of a sentence needs to be capitalized, so 〈, she〉 needs to be changed to 『. She』 to comply with written expression norms.
error_sentence: A young lady is looking at a dress that suitable for her.
correct_sentence: A young lady is looking at a dress that is suitable for her.
correction: is
error_type: Verb Choice Error
error_severity: 3
error_description: Sentence Structure Error: According to English grammar rules, this sentence lacks a predicate; the original phrase 〈that suitable for her〉 is a subject-complement structure missing a linking verb, so the linking verb 『is』 needs to be added to connect the subject and the complement, forming the complete 『that is suitable』 to comply with English grammar rules.
error_sentence: My mother is trying the shoes she likes.
correct_sentence: My mother is trying on the shoes she likes.
correction: on
error_type: Preposition Error
error_severity: 2
error_description: Preposition Error: According to English expression habits, the verb 〈trying〉 in the original sentence could be misunderstood as “attempting,” which does not conform to the prompt's requirement. The phrasal verb “try on” means “to test clothing by putting it on,” which is a fixed expression. Missing the preposition 『on』 would make the meaning incomplete, so 『on』 needs to be added after 〈trying〉 to comply with English expression habits and the prompt's requirements.
