error_type: Determiner Error
error_severity: 2
error_description: ① Determiner Error: According to English grammar rules, the indefinite article "a" is used to modify singular countable nouns, while "shoes" is a plural noun.

error_type: Subject-Verb Agreement Error
error_severity: 4
error_description: ① Pronoun Error: According to English grammar rules, 〈It〉 in 〈It's〉 is a singular pronoun, which can only refer to singular or uncountable nouns. The items mentioned earlier, 〈shirt and shoes〉, are plural, so 〈It〉 is a pronoun error and should be changed to the plural pronoun 『They』; ② Subject-Verb Agreement Error: When the subject changes from a singular pronoun to the plural pronoun 『They』, according to the principle of subject-verb agreement, the verb must agree with the subject in number. The verb 〈is〉 in the original sentence is used for a singular subject; here, 〈is〉 should be changed to 『are』 to match the plural subject.

error_type: Determiner Error
error_severity: 3

error_type: Subject-Verb Agreement Error
error_severity: 4
error_description: ① Subject-Verb Agreement Error: According to English grammar rules, the third-person singular subject 〈Amy〉 requires the third-person singular form of the verb, so 〈wear〉 is changed to 『wears』; ② Determiner Error: According to English grammar rules, the countable noun 〈dress〉 needs an indefinite article before it to express the singular concept, so 『a』 is added to form a complete object structure.
error_sentence: She wear shoes.
correct_sentence: She wears shoes.
error: wear
correction: wears
error_type: Subject-Verb Agreement Error
error_severity: 3
error_description: Subject-Verb Agreement Error: According to English grammar rules, the subject 〈She〉 is third-person singular, and the verb 〈wear〉 needs to be in the third-person singular form, so 〈wear〉 is changed to 『wears』 to ensure subject-verb agreement.

error: wear
correction: wears
error_type: Subject-Verb Agreement Error
error_severity: 3
error_description: Subject-Verb Agreement Error: According to the English grammar rule that the subject and predicate verb must agree in person and number, the current subject 〈She〉 is third-person singular, while the predicate verb 〈wear〉 is in its base form, violating the subject-verb agreement rule. Therefore, the base form verb 〈wear〉 should be changed to the third-person singular present tense form 『wears』.
error_sentence: She wear pink shoes, pink is my favourite color!
correct_sentence: She wears pink shoes. Pink is my favourite color!
error: , pink
correction: . Pink
error_type: Punctuation Error
error_severity: 3
error_description: ① Punctuation Error: According to English sentence structure rules, the word 〈pink〉 starting the second clause actually begins a new complete sentence and should not be connected to the previous clause with a comma. Therefore, the comma connecting the two clauses needs to be changed to a period 『She wears pink shoes. Pink』 to separate the sentences, allowing each sentence to maintain structural independence; ② Case Error: According to English writing conventions, the first letter of the first word in a sentence must be capitalized. Since the second 〈pink〉 starts a new sentence, its first letter needs to be capitalized, resulting in the final correction 『Pink』 to comply with English capitalization rules.
error_sentence: She very beautifl!
correct_sentence: She is very beautiful!
error: very beautifl
correction: is very beautiful
error_type: Verb Choice Error
error_severity: 4
error_description: ① Verb Choice Error: According to basic English sentence structure, when the adjective phrase 〈very beautiful〉 is used as a predicative, it must form a subject-predicative structure with a linking verb. Since the subject 〈She〉 is third-person singular, the corresponding form of the linking verb 『is』 needs to be added to form the complete and correct structure 『She is very beautiful』; ② Spelling Error: According to English spelling conventions, 〈beautifl〉 is not the correct spelling for the adjective 'beautiful'. The incorrect 〈beautifl〉 should be corrected to the proper spelling 『beautiful』 to ensure word accuracy.

error: doing
error_type: Word Redundancy Error
error_severity: 4
error_description: Word Redundancy Error: According to English expression habits, the verb 〈doing〉 in the phrase 〈doing shopping〉 is redundant because the verb 〈shopping〉 itself already expresses the intention of shopping. Changing 〈doing shopping〉 to 『shopping』 makes the sentence more concise and fluent.
error_sentence: Her mother is trying the shose and her father is staying on the sofa and wait for them.
correct_sentence: Her mother is trying on the shoes and her father is staying on the sofa and waiting for them.

correction: on the shoes
error_type: Preposition Error
error_severity: 3
error_description: ① Preposition Error: According to English grammar rules, the fixed phrase 'try on' should be used to express the action of 'trying on'. The original sentence 〈trying the shose〉 lacks the preposition 〈on〉, which does not conform to grammatical rules, so 『on』 needs to be added after 〈trying〉; ② Spelling Error: According to the sentence meaning, it intends to express 'shoes'. The word 〈shose〉 is misspelled; the correct spelling should be 『shoes』. Therefore, 〈shose〉 needs to be changed to 『shoes』 for correct spelling.
error_sentence: Her mother is trying the shose and her father is staying on the sofa and wait for them.
correct_sentence: Her mother is trying on the shoes and her father is staying on the sofa and waiting for them.
error: wait
correction: waiting
error_type: Verb Tense Error
error_severity: 3
error_description: Verb Tense Error: According to English grammar rules, in a parallel sentence structure, verbs connected by the conjunction 〈and〉 must maintain tense consistency. In the original sentence, the preceding clause 〈is staying〉 is in the present continuous tense, while 〈wait〉 is not in the corresponding present participle form, which is a verb tense error. Therefore, 〈wait〉 needs to be changed to 『waiting』 to maintain tense consistency and conform to grammatical rules.

correct_sentence: This is my father, and he is tall.
error: high
correction: tall
error_type: Adjective Error

error_type: Auxiliary Error
error_severity: 3
error_description: Auxiliary Error: 〈'm〉 is the contracted form of the verb 'be', indicating a state, which does not semantically match the following action verb 〈get up〉; therefore, the auxiliary verb 〈'm〉 needs to be deleted, changing it to 『I get up』 to meet the requirements.

error_type: Noun Error
error_severity: 3

error_severity: 3
error_description: Nonfinite Verb Form Error: According to English fixed phrase rules, the verb 〈help〉 in the structure “help sb do sth” is directly followed by the base form of the verb, without the infinitive marker 〈to〉; therefore, the redundant infinitive marker 『to』 is deleted, correcting it to 『help sb do sth』 to comply with grammatical rules.

error_type: Verb Choice Error
error_severity: 3
error_description: Verb Choice Error: According to English expression norms, when describing an ongoing store sale, the present continuous tense 『is having』 should be used instead of the structure 〈is a big sale〉. Additionally, 〈a big sale〉 is a noun phrase and cannot directly function as a predicate to indicate an ongoing action; the present continuous tense of the verb 'have' is required.

error_sentence: My classmate wear a white shirt and a pait of shoes, is pink.
correct_sentence: My classmate wears a white shirt and a pair of pink shoes.
error: pait of shoes, is pink
correction: pair of pink shoes
error_type: Sentence Structure Error
error_severity: 4
error_description: ① Spelling Error: Based on the sentence's meaning, the intention is to express 'a pair', thus 〈pait〉 is a misspelling of 『pair』; 〈pait〉 needs to be corrected to 『pair』 for the sentence to make sense; ② Sentence Structure Error: According to English grammar rules and common usage, the adjective 〈pink〉 should precede and modify the noun 〈shoes〉. In the original phrase 〈is pink〉, the auxiliary verb 'is' is redundant. The sentence structure should be adjusted by placing 〈pink〉 before 〈shoes〉 to form 『pair of pink shoes』, making the modification relationship clear and the sentence structure correct and fluent.

Therefore, it is corrected to 『and she likes them』 to ensure the sentence is coherent and the pronouns are correct.
