error_type: Spelling Error
error_severity: 2
error_description: ① Space Error: According to English writing conventions, when 〈pm〉 indicates a time in the afternoon, it should be separated from the preceding time by a space, so a space should be added between 〈3:00〉 and 〈pm〉 to conform to standard time format; ② Spelling Error: Based on the following 〈the market〉, it is known that the intended expression here is the adverbial phrase of place 'in the market', therefore 〈n〉 is a spelling error of the preposition and should be completed as 『in』 to form the correct adverbial phrase of place.

error_sentence: At 3:00pm n the market costumers are shopping .
correct_sentence: At 3:00 pm in the market, customers are shopping.
error: costumers
correction: , customers
error_type: Punctuation Error
error_severity: 3
error_description: ① Punctuation Error: According to English expression habits, when an adverbial of time/place is placed at the beginning of a sentence, it is generally separated from the main clause by a comma 『,』 to make the sentence structure clearer. Therefore, since 『At 3:00 pm in the market』 is an adverbial of time and place at the beginning of the sentence, a punctuation mark is missing between it and the following main clause; a comma 『,』 should be added before the subject of the main clause 『customers』 to conform to English writing norms; ② Spelling Error: 〈costumers〉 means 'suppliers of theatrical costumes'; based on the following 〈are shopping〉, it is inferred that 〈costumers〉 is a spelling error for 『customers』, so 〈costumers〉 is corrected to 『customers』 to make the sentence meaning coherent and logical.

error_sentence: One little girl buying some food for dinner .
correct_sentence: One little girl is buying some food for dinner.
correction: is
error_type: Auxiliary Error
error_severity: 3
error_description: Auxiliary Error: From the context, it is known that the tense for actions throughout the text is present continuous. According to the rules for expressing the present continuous tense of verbs, the complete structure should include a be verb (am/is/are) + present participle; the original sentence is missing the corresponding be verb for 〈buying〉. Since the subject 〈One little girl〉 is third-person singular, the third-person singular form of the be verb 『is』 needs to be added before the present participle 〈buying〉 to form the complete verb tense structure.

error_sentence: One little girl buying some food for dinner . young lady looking at a dress.
correct_sentence: A young lady is looking at a dress.
correction: A
error_type: Determiner Error
error_severity: 2
error_description: Determiner Error: Based on the following 〈is looking〉, it is known that the subject of the sentence should be third-person singular. To meet this condition, the singular countable noun 〈young lady〉 is missing a determiner before it, and since it does not refer to a specific lady, the indefinite article 『A』 should be added before 〈young lady〉 to comply with English grammar rules.

error_sentence: young lady looking at a dress.
correct_sentence: A young lady is looking at a dress.
correction: is
error_type: Auxiliary Error
error_severity: 2
error_description: Auxiliary Error: From the context, it is known that the tense for actions throughout the text is present continuous. According to the rules for expressing the present continuous tense of verbs, the complete structure should include a be verb (am/is/are) + present participle; the original sentence is missing the corresponding be verb for 〈looking〉. Since the subject 『A young lady』 is third-person singular, the third-person singular form of the be verb 『is』 needs to be added before the present participle 〈looking〉 to form the complete present continuous verb structure.

error_sentence: In shoes market Linda's mothrer trying the shoes, at the same time, Linda's father staying on the sofa and waiting for Linda's mother come back.
correct_sentence: In the shoe shop, Linda's mother is trying on the shoes, and at the same time, Linda's father is staying on the sofa and waiting for Linda's mother to come back.
error: shoes market
correction: the shoe shop,
error_type: Noun Error
error_severity: 4
error_description: ① Determiner Error: 『shoe shop』 is a singular countable noun, missing a determiner for modification here, so the definite article 『the』 is added to form the complete noun phrase 『the shoe shop』; ② Noun Number Error: According to English expression rules, when countable noun A modifies noun B as an attribute, the singular form of noun A should be used, thus the noun 〈shoes〉 in 〈shoes market〉 in the original sentence has a number error, and 〈shoes〉 should be changed to the singular 『shoe』 to modify 『shop』 as an attribute to conform to norms; ③ Noun Error: According to the prompt 'what Linda sees and hears at the mall', the intended meaning here should be 'shoe shop'; the phrase 〈shoes market〉 in the original sentence means 'shoe market/bazaar', which does not fit the sentence's meaning, indicating a noun choice error; 〈market〉 should be changed to 『shop』 to better fit the sentence's logic.

error_sentence: In shoes market Linda's mothrer trying the shoes, at the same time, Linda's father staying on the sofa and waiting for Linda's mother come back.
correct_sentence: In the shoe shop, Linda's mother is trying on the shoes, and at the same time, Linda's father is staying on the sofa and waiting for Linda's mother to come back.
error: mothrer trying
correction: mother is trying on
error_type: Auxiliary Error
error_severity: 4
error_description: ① Spelling Error: According to the prompt 'Linda's mother', it is known that the subject 〈mothrer〉 in the original sentence is a misspelling of 『mother』, so 〈mothrer〉 should be changed to 『mother』 to correctly express the meaning of 'mother'; ② Auxiliary Error: From the context, it is known that the tense for actions throughout the text is present continuous. According to the rules for expressing the present continuous tense of verbs, the complete structure should include a be verb (am/is/are) + present participle; the original sentence is missing the corresponding be verb for 〈trying〉. Since the subject 〈Linda's mother〉 is third-person singular, the third-person singular form of the be verb 『is』 needs to be added before the present participle 〈trying〉 to form the complete verb tense structure; ③ Preposition Error: According to 'try on the shoes' provided in the prompt, the phrasal verb 'try on' is a fixed expression meaning 'to try on (shoes)', therefore the original sentence is missing a preposition; the preposition 『on』 needs to be added before 〈the shoes〉 to meet the prompt's requirement.

error_sentence: In shoes market Linda's mothrer trying the shoes, at the same time, Linda's father staying on the sofa and waiting for Linda's mother come back.
correct_sentence: In the shoe shop, Linda's mother is trying on the shoes, and at the same time, Linda's father is staying on the sofa and waiting for Linda's mother to come back.
correction: and
error_type: Conjunction Error
error_severity: 3
error_description: Conjunction Error: 〈Linda's mother is trying on the shoes〉 and 〈Linda's father is staying on the sofa and waiting for Linda's mother to come back〉 each have independent predicate verbs and are two independent clauses. Since these two independent clauses are separated by a comma, a conjunction is missing here. Based on the meaning, the two sentences have a coordinate relationship, so the conjunction 『and』 should be added before 〈at〉 to comply with English grammar rules and clarify the logical relationship between the two sentences.

error_sentence: In shoes market Linda's mothrer trying the shoes, at the same time, Linda's father staying on the sofa and waiting for Linda's mother come back.
correct_sentence: In the shoe shop, Linda's mother is trying on the shoes, and at the same time, Linda's father is staying on the sofa and waiting for Linda's mother to come back.
correction: is
error_type: Auxiliary Error
error_severity: 2
error_description: Auxiliary Error: From the context, it is known that the tense for actions throughout the text is present continuous. According to the rules for expressing the present continuous tense of verbs, the complete structure should include a be verb (am/is/are) + present participle; the original sentence is missing the corresponding be verb for 〈staying〉. Since the subject 『Linda's father』 is third-person singular, the third-person singular form of the be verb 『is』 needs to be added before the present participle 〈staying〉 to form the complete present continuous verb structure.

error_sentence: In shoes market Linda's mothrer trying the shoes, at the same time, Linda's father staying on the sofa and waiting for Linda's mother come back.
correct_sentence: In the shoe shop, Linda's mother is trying on the shoes, and at the same time, Linda's father is staying on the sofa and waiting for Linda's mother to come back.
correction: to
error_type: Nonfinite Verb Form Error
error_severity: 2
error_description: Nonfinite Verb Form Error: From the context, it is known that the original sentence intends to express the fixed phrase 'wait for someone to do something'; 〈Linda's mother〉 corresponds to 'someone' introduced by the preposition 〈for〉, and 〈come back〉 corresponds to 'do something', which should appear in the infinitive form. Therefore, there is a nonfinite verb form error here; 『to』 should be added before the original verb 〈come〉 to form the correct infinitive phrase.
