error_type: Sentence Structure Error
error_severity: 3
error_description: ① Punctuation Error: According to English grammar rules and conventions, when a time adverbial is placed at the beginning of a sentence, it is usually separated from the main clause by a comma to indicate its modifying relationship. In the original sentence, the time adverbial “At three o'clock in the afternoon” is connected to the main clause “Linda in the shop...” with a period, which is incorrect; 〈. 〉 should be changed to 『, 』; ② Sentence Structure Error: A complete sentence requires a subject-verb structure. The original phrase “Linda in the shop...” lacks a predicate verb. With “Linda” as the subject, the linking verb “is” needs to be added to form a complete subject-verb structure; 『is』 should be added after 〈Linda〉 to express the meaning “Linda is in the shop”.
error_sentence: Linda in the shop whit her mother and father.
correct_sentence: At three o'clock in the afternoon, Linda is in the shop with her mother and father.
error: whit
correction: with
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: According to the meaning of the sentence, the intention is to express “Linda is in the shop with her parents”. In English, “with” is used to express “together with”. Therefore, 〈whit〉 is a misspelling of 『with』 and needs to be corrected to 『with』 to make the sentence coherent.
error_sentence: In the shop Limda after seeing a little girl is buying some food, a young lady is looking at a dress.
correct_sentence: In the shop, Linda sees a little girl buying some food and a young lady looking at a dress.

error_type: Sentence Structure Error
error_severity: 4
error_description: ① Punctuation Error: When the place adverbial 〈In the shop〉 is at the beginning of the sentence, it needs to be separated from the main clause, so a comma should be added after it; ② Spelling Error: According to the sentence meaning, the intention is to express the name “Linda”. Here, 〈Limda〉 is a misspelling of 『Linda』 and needs to be corrected to 『Linda』 for clarity; ③ Sentence Structure Error: According to English grammar, a sentence must have a correct subject-verb structure. The original phrase “Limda after seeing” does not form a correct subject-verb relationship, indicating a sentence structure error. Therefore, 〈Limda after seeing〉 needs to be changed to 『Linda sees』 to conform to standard expression.

correct_sentence: In the shop, Linda sees a little girl buying some food and a young lady looking at a dress.

error_type: Word Redundancy Error
error_severity: 4
error_description: Word Redundancy Error: According to English convention, the expression for “see someone doing something” is “see sb. doing sth.”. In this structure, the verb 〈is〉 in 〈is buying〉 is a redundant component. Therefore, 〈is〉 should be deleted to avoid word redundancy.

error_type: Conjunction Error
error_severity: 4
error_description: Conjunction Error: According to English grammar rules, in the structure “see sb. doing sth.”, “a little girl buying some food” and “a young lady looking at a dress” are parallel elements and cannot be connected by a comma. 〈,〉 should be replaced with 『and』 to make the sentence structure correct and conform to English expression conventions.
error_sentence: In the shop Limda after seeing a little girl is buying some food, a young lady is looking at a dress.
correct_sentence: In the shop, Linda sees a little girl buying some food and a young lady looking at a dress.

error_type: Word Redundancy Error
error_severity: 4
error_description: Word Redundancy Error: According to English convention, the expression for “see someone doing something” is “see sb. doing sth.”. In this structure, the verb 〈is〉 in 〈is looking at〉 is a redundant component. Therefore, 〈is〉 should be deleted to avoid word redundancy.
error_sentence: Linda's mother is trying the shoes.
correct_sentence: Linda's mother is trying on the shoes.
correction: on
error_type: Preposition Error
error_severity: 3
error_description: Preposition Error: According to English grammar rules and conventions, “try on” is a fixed phrase used to express the action of “trying on” clothes or shoes. The original phrase 〈trying the shoes〉 is missing the preposition 〈on〉, which is a preposition error. 『on』 needs to be added after 〈trying〉, changing it to 『trying on the shoes』, so the sentence accurately expresses the meaning of “trying on the shoes” and follows correct English usage.
error_sentence: She's father is staying on the sofa reading a book, and waiting for her mom.
correct_sentence: Her father is staying on the sofa, reading a book, and waiting for her mom.
error: She's
correction: Her
error_type: Pronoun Error
error_severity: 3
error_description: Pronoun Error: According to English grammar rules, a possessive pronoun is required to express possession. In the original sentence, 〈She's〉 is the contraction of “She is” and cannot be used here to indicate possession; this is a pronoun error. 〈Her〉 is the possessive pronoun that correctly expresses the possessive relationship “her”, referring to 〈father〉. Therefore, 〈She's〉 should be changed to 『Her』 to conform to English grammar and conventions.
error_sentence: She's father is staying on the sofa reading a book, and waiting for her mom.
correct_sentence: Her father is staying on the sofa, reading a book, and waiting for her mom.
correction: ,
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English punctuation rules, when the participle phrase 〈reading a book〉 functions as an adverbial of attendant circumstances, it needs to be separated from the main clause by a comma to clearly demarcate the sentence structure. The original sentence lacks a comma between 〈sofa〉 and 〈reading〉, which is a punctuation error. A comma 『,』 should be added after 〈sofa〉 to make the sentence structure clearer and conform to English punctuation conventions.
