error_type: Nonfinite Verb Form Error
error_severity: 3
error_description: Nonfinite Verb Form Error: According to the rules for forming present continuous interrogative sentences in English, the structure requires 'wh-word + be verb + subject + present participle'. In the original sentence 〈What is she buy〉, the verb 〈buy〉 is in its base form; it should be changed to the present participle form 『buying』 to form the grammatically correct present continuous interrogative structure 『What is she buying?』, accurately expressing the present continuous meaning of 'What is she buying?'.

error_sentence: She is buy a tomato, three cucumbers and an apple.
correct_sentence: She is buying a tomato, three cucumbers and an apple.
error: buy
correction: buying
error_type: Nonfinite Verb Form Error
error_severity: 3
error_description: Nonfinite Verb Form Error: According to the rules for forming present continuous affirmative sentences in English, the original sentence 〈She is buy〉 has an incorrect verb form. The present continuous tense requires the 'be verb + V-ing' structure; therefore, the base form verb 〈buy〉 is changed to the present participle 『buying』, corrected to 『She is buying』, making the sentence conform to the standard grammatical framework of the present continuous tense and accurately expressing the ongoing action of 'she is buying'.

error_type: Determiner Error
error_severity: 2
error_description: Determiner Error: According to the rules for forming countable noun phrases in English, the singular countable noun 〈fashion clothes shop〉 must have a determiner when used as a common noun. Here, it means 'a' clothing store, so the indefinite article 『a』 needs to be added to form the complete noun phrase 『a fashion clothes shop』, meeting English grammatical structure requirements.

error_sentence: A young lady is in fashion clothes shopping looking at a dress.
correct_sentence: A young lady is in a fashion clothes shop, looking at a dress.
error: shopping
correction: shop,
error_type: PoS Confusion Error
error_severity: 4
error_description: ① PoS Confusion Error: According to English norms for expressing location, 〈shopping〉 as a gerund denotes the 'act of shopping', whereas the context requires a specific place noun. Therefore, the action noun 〈shopping〉 is changed to the physical place noun 『shop』, forming the accurate adverbial phrase of place 『in a fashion clothes shop』, conforming to the 'preposition + place noun' grammatical structure requirement; ② Punctuation Error: According to English rules for separating parallel actions, a comma is needed to separate a non-restrictive participial phrase. Therefore, a comma 『,』 is added after the main clause 『A young lady is in a fashion clothes shop』 to correctly separate the participial phrase 『looking at a dress』 from the main clause, ultimately forming a complete sentence structure that conforms to English writing conventions.

error_sentence: Linda's mother is in fashion shoes shopping to trying the shoes and Linda's father is staying on the sofa reading the book, waitting for Linda's mother.
correct_sentence: Linda's mother is in a fashion shoe shop, trying on the shoes, and Linda's father is staying on the sofa, reading a book, and waiting for Linda's mother.
error: fashion shoes shopping to trying
correction: a fashion shoe shop, trying on
error_type: PoS Confusion Error
error_severity: 5
error_description: ① Determiner Error: According to the rules for forming countable noun phrases in English, the singular countable noun 〈fashion shoe shop〉 must have a determiner when used as a common noun. Here, it means 'a' shoe store, so the indefinite article 『a』 needs to be added to form the complete noun phrase 『a fashion shoe shop』, meeting English grammatical structure requirements; ② Noun Number Error: According to English grammar rules, when referring to 'a shoe store', the singular noun 'shoe' is used to modify the noun 'shop'; therefore, 〈shoes shopping〉 needs to be changed to 『shoe shop』 to comply with the singular noun principle; ③ PoS Confusion Error: According to English norms for expressing location, 〈shopping〉 as a gerund denotes the 'act of shopping', whereas the context requires a specific place noun. Therefore, the action noun 〈shopping〉 is changed to the physical place noun 『shop』, forming the accurate adverbial phrase of place 『in a fashion shoe shop』, conforming to the 'preposition + place noun' grammatical structure requirement; ④ Punctuation Error: According to English rules for separating parallel actions, when a sentence contains multiple simultaneous actions, a comma is needed to separate a non-restrictive participial phrase. Therefore, a comma is added after the main clause 『A young lady is in a fashion clothes shop』, forming the participial phrase 『, looking at a dress』 correctly separated from the main clause, ultimately forming a complete sentence structure that conforms to English writing conventions; ⑤ Nonfinite Verb Form Error: According to the grammatical rules for using present participles as adverbial phrases, the original phrase 〈to trying〉 incorrectly mixes the infinitive marker 〈to〉 and the present participle 〈trying〉. The infinitive marker 〈to〉 should be removed, retaining the present participle 〈trying〉 to form the present participle phrase 『trying on the shoes』, accurately expressing the 'trying on' action occurring simultaneously with the main clause action, conforming to the adverbial phrase structure requirement; ⑥ Preposition Error: According to English grammar and the original prompt requirements, when expressing 'try on', the phrasal verb 'try on' should be used instead of the single verb 'try'; therefore, the correct expression here should be 『, trying on』.

error_sentence: Linda's mother is in fashion shoes shopping to trying the shoes and Linda's father is staying on the sofa reading the book, waitting for Linda's mother.
correct_sentence: Linda's mother is in a fashion shoe shop, trying on the shoes, and Linda's father is staying on the sofa, reading a book, and waiting for Linda's mother.
correction: ,
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English rules for separating parallel actions, when the adverbial phrase of place 〈at a fashion clothes shop〉 and the accompanying action 〈trying on the shoes〉 appear in parallel, a comma is needed for separation. Therefore, adding a comma after 〈shop〉 forms the correct structure 『at a fashion clothes shop, trying on the shoes』, maintaining semantic coherence and conforming to English punctuation norms for parallel components. It is acceptable not to add the comma.

error_sentence: Linda's mother is in fashion shoes shopping to trying the shoes and Linda's father is staying on the sofa reading the book, waitting for Linda's mother.
correct_sentence: Linda's mother is in a fashion shoe shop, trying on the shoes, and Linda's father is staying on the sofa, reading a book, and waiting for Linda's mother.
error: reading the
correction: , reading a
error_type: Determiner Error
error_severity: 4
error_description: ① Punctuation Error: According to English punctuation rules for participial phrases, when a main clause (expressing the main action) is followed by a present participle phrase (expressing a simultaneous action), a comma is needed for separation. Therefore, a comma is added after the main clause 『Linda's father is staying on the sofa』 to correctly separate the participial phrase 『reading a book』 from the main clause, resulting in the complete sentence 『Linda's father is staying on the sofa, reading a book.』, fully complying with English complex sentence punctuation norms; ② Determiner Error: According to English article usage rules, the original phrase 〈the book〉 uses the definite article to refer to a specific, known book, but the context here describes a general scene and does not specify a particular book. Therefore, the definite article 〈the〉 is changed to the indefinite article 『a』, forming the indefinite expression 『a book』, conforming to the grammatical norm of 'using an indefinite article for non-specific items'.

error_sentence: Linda's mother is in fashion shoes shopping to trying the shoes and Linda's father is staying on the sofa reading the book, waitting for Linda's mother.
correct_sentence: Linda's mother is in a fashion shoe shop, trying on the shoes, and Linda's father is staying on the sofa, reading a book, and waiting for Linda's mother.
error: waitting
correction: and waiting
error_type: Conjunction Error
error_severity: 4
error_description: ① Conjunction Error: According to English norms for expressing parallel actions, when describing two consecutive actions performed by the subject, the coordinating conjunction 『and』 should be used for connection. Therefore, the conjunction 『and』 is added before 〈waiting〉, forming the complete structure 『reading a book, and waiting for Linda's mother.』, which maintains the parallel relationship of the actions and conforms to English parallel structure requirements; ② Spelling Error: According to the rules for forming the present participle of English verbs ending in a stressed closed syllable with a single final consonant (wait), the final consonant 't' should be doubled before adding -ing. The original word 〈waitting〉 incorrectly includes an extra letter 't'. The correct form, following the rule of doubling 't' and adding -ing, is 『waiting』, which constitutes the correctly spelled present participle form.
