error_type: Word Redundancy Error
error_severity: 5
error_description: ① Sentence Structure Error: According to basic English sentence patterns, the main clause 〈Mr. Cool's Clothes Store will big expensive〉 lacks a predicate verb; therefore, the transitive verb 『have』 is added and the structure is adjusted to [Mr. Cool's Clothes Store will have a big sale] to form a complete subject-verb-object structure.; ② PoS Confusion Error: The adjective phrase 〈big expensive〉 does not fit the sentence meaning (expressing a promotional event); it should be changed to the noun phrase 『a big sale』, because 『sale』 (promotion) is the core object of the sentence and needs a determiner and modifier.; ③ Punctuation Error: The extra apostrophe in 〈Lot's of〉 does not conform to English possessive/contraction rules; it should be corrected to 『Lots of』 (meaning "many"), as it is not a possessive or contraction here.; ④ Spelling Error: Based on the context, 〈pepon〉 is misspelled; the correct word should be 『people』, so the spelling is corrected to comply with English vocabulary norms.; ⑤ Word Redundancy Error: The phrase 〈go to the shopping〉 is redundant; according to the English fixed phrase, "to go shopping" should use 『go shopping』 (verb + gerund structure), deleting the extra preposition 『to the』 makes the expression more concise and natural.

error_sentence: Kind of coluor jacket is 30 yuan.
correct_sentence: All kinds of colored jackets are 30 yuan.
error: Kind of coluor jacket is
correction: All kinds of colored jackets are
error_type: PoS Confusion Error
error_severity: 5
error_description: ① Determiner Error: According to English grammar rules, 〈Kind of〉 is used with singular or uncountable nouns, but here it needs to express "multiple types"; therefore, the singular determiner 〈Kind of〉 is changed to the plural form 『All kinds of』 to correctly modify the plural noun.; ② Noun Number Error: The subject 〈Kind〉 should be in the plural form 『All kinds』 to match the sentence meaning (emphasizing diversity). The countable noun 〈jacket〉 needs to be changed to the plural form 『jackets』 to maintain number agreement with 『All kinds of』.; ③ PoS Confusion Error: The noun 〈coluor〉 is a misspelling of 『colour』 and its part of speech is used incorrectly; according to the sentence meaning (describing the color of the jackets), the adjective 『colored』 should be used to modify 『jackets』, so it is corrected to 『colored jackets』.; ④ Subject-Verb Agreement Error: The subject 『jackets』 is plural, while the predicate 〈is〉 is singular, violating the subject-verb agreement principle; therefore, the be-verb is changed to the plural form 『are』, finally adjusted to 『All kinds of colored jackets are...』.

error_sentence: Shirt is 20 yuan.
correct_sentence: Shorts are 20 yuan.
error: Shirt is
correction: Shorts are
error_type: Subject-Verb Agreement Error
error_severity: 5
error_description: ① Noun Error: Based on the context and product category, 〈Shirt〉 does not match the actual item described; it should be corrected to 『Shorts』 to ensure the noun accurately represents the item.; ② Subject-Verb Agreement Error: The subject 『Shorts』 is a plural noun, while the original predicate verb 〈is〉 is singular, violating the subject-verb agreement principle in English grammar; therefore, the be-verb is adjusted to the plural form 『are』 to make the sentence structure correct. The modification results in 『Shorts are...』.

error_sentence: Blouse ia 25 yuan.
correct_sentence: Blouses are 25 yuan.
error: Blouse ia
correction: Blouses are
error_type: Subject-Verb Agreement Error
error_severity: 5
error_description: ① Noun Number Error: Based on the context of the price description (usually for multiple items), the singular noun 〈Blouse〉 is illogical; it should be changed to the plural form 『Blouses』 to indicate items displayed or sold in bulk.; ② Subject-Verb Agreement Error: The original predicate verb 〈ia〉 is misspelled and does not agree with the plural subject 『Blouses』. According to English grammar rules, a plural subject requires the plural be-verb 『are』; therefore, it is corrected to 『Blouses are...』 to ensure subject-verb agreement.

error_sentence: There are beautiful something. Big handbag buy 35 yuan, small handbag buy 20 yuan.
correct_sentence: There are beautiful items. A big handbag costs 35 yuan, and a small handbag costs 20 yuan.
error: something. Big handbag buy
correction: items. A big handbag costs
error_type: Verb Choice Error
error_severity: 5
error_description: ① Noun Error: Based on the context, 〈something〉 is vague and does not meet the requirement for specificity in product description; it should be changed to the specific noun 『items』 to make the meaning clearer and more precise.; ② Determiner Error: The countable noun phrase 〈Big handbag〉 lacks the necessary article, violating English grammar rules. According to the principle that singular countable nouns require a determiner, the indefinite article 『A』 is added, correcting it to 『A big handbag』 to ensure structural completeness.; ③ Verb Choice Error: The original verb 〈buy〉 (to purchase) does not fit the context of expressing "price," creating a logical contradiction. Based on the sentence meaning (stating the product price), the transitive verb 『costs』 should be used, modifying it to 『A big handbag costs...』 to accurately convey the price information.

error_sentence: Big handbag buy 35 yuan, small handbag buy 20 yuan.
correct_sentence: A big handbag costs 35 yuan, and a small handbag costs 20 yuan.
correction: and a
error_type: Conjunction Error
error_severity: 5
error_description: ① Conjunction Error: According to English grammar rules, two independent clauses need to be connected by a coordinating conjunction. Therefore, the coordinating conjunction 『and』 is added to form a compound sentence structure.; ② Determiner Error: According to the rules for forming English noun phrases, the singular countable noun 〈small handbag〉 requires a determiner. Therefore, the indefinite article 『a』 is added to form the complete noun phrase 『a small handbag』 to ensure grammatical completeness.

error_sentence: Big handbag buy 35 yuan, small handbag buy 20 yuan.
correct_sentence: A big handbag costs 35 yuan, and a small handbag costs 20 yuan.
error: buy
correction: costs
error_type: Verb Choice Error
error_severity: 3
error_description: Verb Choice Error: The original verb 〈buy〉 (to purchase) does not fit the context of expressing "price," creating a logical contradiction. Based on the sentence meaning (stating the product price) and the singular subject 〈a small handbag〉, the transitive verb 『costs』 should be used, modifying it to 『a small handbag costs...』 to accurately convey the price information.

error_sentence: Has got lots of beautiful dresses, shoes.
correct_sentence: There are lots of beautiful dresses and shoes.
error: Has got
correction: There are
error_type: Sentence Structure Error
error_severity: 3
error_description: Sentence Structure Error: According to the grammar rules of English existential sentences (There be pattern), the 『There be』 structure should be used to express objective existence. The original phrase 〈Has got〉 expresses possession and does not meet the grammatical requirements for an existential sentence; therefore, it is changed to the existential structure 『There are』 to correctly express the meaning of objective existence.

error_sentence: Has got lots of beautiful dresses, shoes.
correct_sentence: There are lots of beautiful dresses and shoes.
error: ,
correction: and
error_type: Conjunction Error
error_severity: 3
error_description: Conjunction Error: According to English rules for parallel structures, multiple parallel noun phrases must be connected by a coordinating conjunction. The comma in the original sentence cannot function as a conjunction; therefore, the comma 〈,〉 is changed to the coordinating conjunction 『and』 to correctly connect the noun phrases, ensuring the sentence structure is complete.

error_sentence: Welcome choose shopping.
correct_sentence: Welcome to choose and shop.
error: choose shopping
correction: to choose and shop
error_type: Conjunction Error
error_severity: 5
error_description: ① Nonfinite Verb Form Error: According to the usage rules of English infinitives, 〈welcome〉 should be followed by an infinitive structure with 『to』. The original phrase 〈welcome choose〉 lacks the infinitive marker; therefore, it is modified to 『welcome to choose』 to conform to grammatical norms.; ② Conjunction Error: According to English rules for parallel structures, the two verb phrases 〈choose〉 and 〈shop〉 need to be connected by a coordinating conjunction. Therefore, 『and』 is added to form 『choose and shop』, making the sentence structure complete and logical.; ③ PoS Confusion Error: According to the sentence meaning, the base form of the verb should be used here to express actions, whereas 〈shopping〉 is a gerund/present participle form, which does not meet the requirement for expressing parallel actions. Therefore, 〈shopping〉 is changed to the base verb form 『shop』, so that 〈choose〉 and 『shop』 maintain grammatical consistency.
