Error analysis:
error_sentence: Today, my classmate wear a white shirt, 2 pink shoes and a grey skirt.
correct_sentence: Today, my classmate wears a white shirt, a pair of pink shoes and a grey skirt.
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 〈my classmate〉 is third-person singular, therefore the predicate verb needs to use the singular form. The original sentence uses the plural verb 〈wear〉 which does not conform to the subject-verb agreement principle, and should be changed to the third-person singular form 『wears』.
error_sentence: Today, my classmate wear a white shirt, 2 pink shoes and a grey skirt.
correct_sentence: Today, my classmate wears a white shirt, a pair of pink shoes and a grey skirt.
error: 2
correction: a pair of
error_type: Number Error
error_severity: 2
error_description: Number Error: According to English usage, the quantity expression for paired items like shoes requires a unit quantifier. To express “one pair, two items”, “a pair of” is needed. The cardinal number 〈2〉 directly modifying 〈shoes〉 does not conform to English expression norms, therefore 〈2 shoes〉 should be modified to 『a pair of shoes』.
error_sentence: It is very beautiful.
correct_sentence: They are very beautiful.
error: It is
correction: They are
error_type: Pronoun Error
error_severity: 3
error_description: ① Pronoun Error: According to the pronoun agreement principle in English grammar, plural noun phrases require plural pronouns for reference. The original sentence uses the singular pronoun 〈It〉 causing inconsistent reference, therefore it should be changed to the plural subject pronoun 『They』, ensuring the pronoun agrees in number with its antecedent; ② Subject-Verb Agreement Error: Based on English subject-verb agreement rules, when the subject is the plural pronoun 『They』, the linking verb needs to use the plural form. The original sentence's singular linking verb 〈is〉 does not agree with the plural subject, hence it should be adjusted to the plural form 『are』.
error_sentence: I like it.
correct_sentence: I like them.
error: it
correction: them
error_type: Pronoun Error
error_severity: 2
error_description: Pronoun Error: According to the English pronoun reference principle, when the object of the verb 〈like〉 refers to preceding plural nouns, the plural object pronoun must be used, therefore the pronoun 〈it〉 needs to be modified to the pronoun 『them』 to correctly refer to the plural objects.

Error analysis:
error_sentence: I from China .
correct_sentence: I am from China.
correction: am
error_type: Verb Choice Error
error_severity: 3
error_description: Verb Choice Error: According to basic English sentence structure rules, in the declarative sentence structure 'Subject + Linking Verb + Predicative', the subject 〈I〉 must be paired with the linking verb 『am』 to form a complete predicate. Therefore, the linking verb needs to be added to 〈I from China〉 to form the correct structure 『I am from China』.
error_sentence: I have a bast firend .
correct_sentence: I have a best friend.
error: bast firend
correction: best friend
error_type: Spelling Error
error_severity: 2
error_description: ① Spelling Error: According to English pronunciation rules and common vocabulary spelling, the superlative adjective 〈bast〉 has incorrect letter order and should be corrected to the proper spelling 『best』 to accurately express the meaning 'best'; ② Spelling Error: According to English word formation, the noun 〈firend〉 is misspelled; the correct spelling should be 『friend』 to conform to English standards.
error_sentence: She likes wearing blue shirts and blue shoes . because she favourite colour is blue .
correct_sentence: She likes wearing blue shirts and blue shoes, because her favourite colour is blue.
error: . because she
correction: , because her
error_type: Pronoun Error
error_severity: 3
error_description: ① Punctuation Error: According to English complex sentence grammar rules, the subordinate clause of reason introduced by the subordinating conjunction 〈because〉 cannot stand alone as a sentence and must be connected to the main clause with a comma. Therefore, the original period is changed to 『,』 to form the correct main-subordinate structure; ② Pronoun Error: To express possession according to the sentence's meaning, the subjective pronoun 〈she〉 needs to be changed to the possessive form 『her』, forming the determiner phrase 『her favorite color』, to comply with the grammatical norm of possessive adjective + noun.

Error analysis:
error_sentence: It's 3:00 pm.
correct_sentence: It's 3:00 p.m. I am going shopping with my parents.
error: pm.
correction: p.m.
error_type: Contraction Error
error_severity: 2
error_description: Contraction Error: According to English writing conventions, the Latin abbreviation 〈pm〉 as a time suffix should include periods. Therefore, the time expression 〈3:00 pm.〉 is modified to the standard format 『3:00 p.m.』 to comply with standard usage.
error_sentence: Look, there is a little girl; she is buying some food she likes.
correct_sentence: Look, there is a little girl. She is buying some food she likes.
error: ; she
correction: . She
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English grammar rules, a semicolon 〈;〉 cannot connect two complete independent clauses. Therefore, the misused semicolon is changed to a period 『.』 to achieve correct sentence separation, and the first letter of the sentence must be capitalized, so the pronoun 〈she〉 is corrected to the capitalized 『She』 to ensure compliance with standard format.
error_sentence: My mother is trying the shoes.
correct_sentence: My mother is trying on the shoes.
correction: on
error_type: Preposition Error
error_severity: 2
error_description: Preposition Error: According to the usage rules of English phrasal verbs, when 『try on』 is used as a fixed phrase meaning 'to test clothing by putting it on', the preposition 『on』 cannot be omitted. Therefore, the missing preposition 『on』 needs to be added after the present participle 〈trying〉, correcting the incomplete phrase 〈trying the shoes〉 to the grammatically correct and complete collocation 『trying on the shoes』.

error: Summer
correction: summer
error_type: Case Error
error_severity: 1
error_description: ① Case Error: According to English writing conventions, the first letter of a season name does not need to be capitalized in non-specific contexts. In the original sentence, 〈Summer〉 is capitalized, which does not conform to the rule; this is a case error. 〈Summer〉 needs to be changed to the lowercase form 『summer』 to comply with English capitalization rules.
error_sentence: I'mm going to Tian'an men Square and the Palace Museum.
correct_sentence: I'm going to Tian'anmen Square and the Palace Museum.
error: I'mm
correction: I'm
error_type: Spelling Error
error_severity: 2
error_description: ① Spelling Error: According to the sentence meaning, the intention here is to express 'I plan to go to Tian'anmen Square and the Palace Museum'. 〈I'mm〉 is an incorrect spelling, with an extra letter 〈m〉, and is not the correct contraction form. 〈I'm〉 is the correct contraction of 〈I am〉, therefore 〈I'mm〉 is a misspelling of 『I'm』. 〈I'mm〉 needs to be corrected to 『I'm』 to make the sentence coherent.
error_sentence: I'mm going to Tian'an men Square and the Palace Museum.
correct_sentence: I'm going to Tian'anmen Square and the Palace Museum.
error: Tian'an men
correction: Tian'anmen
error_type: Spelling Error
error_severity: 1
error_description: ① Spelling Error: According to English writing conventions, the spelling of proper nouns should be kept as a single word. In the original sentence, there is an extra space in 〈Tian'an men〉, which does not conform to the correct spelling of the proper noun 'Tian'anmen'; this is a spelling error. 〈Tian'an men〉 needs to be corrected to the single word form 『Tian'anmen』 to comply with English writing conventions.

She is very beautiful. She has short hair. The happy boy is my brother. He likes sports. He is 14 years old. I am happy, too. I have a good family.

Error analysis:
error_sentence: He likes clean.
correct_sentence: He likes cleanliness.
error: clean
correction: cleanliness
error_type: PoS Confusion Error
error_severity: 4
error_description: ① PoS Confusion Error: According to English grammar rules, the transitive verb 〈likes〉 requires a noun as its object; 〈clean〉 is an adjective and cannot serve as an object, constituting a morphology error / PoS confusion. Therefore, 〈clean〉 needs to be changed to the noun form 『cleanliness』 to comply with grammatical rules and convey the intended meaning.
error_sentence: He likes spot.
correct_sentence: He likes sports.
error: spot
correction: sports
error_type: Noun Error
error_severity: 3
error_description: ① Noun Error: Based on the sentence's meaning, the intended expression is “sports”; however, the noun 〈spot〉 means “spot” or “place”, which does not match the context's intended meaning of “sports”. This is a noun error, requiring 〈spot〉 to be changed to 『sports』 to fit the semantic needs.
error_sentence: I have good family.
correct_sentence: I have a good family.
correction: a
error_type: Determiner Error
error_severity: 2
error_description: ① Determiner Error: According to English grammar rules, the singular countable noun 〈family〉 requires a determiner before it to indicate “one”. The original phrase 〈good family〉 lacks a determiner, constituting a determiner error. Therefore, 『a』 needs to be inserted before 〈good family〉 to ensure the sentence conforms to English grammar standards and is structurally complete.

I have eight classes on Monday. I have lunch at about twelve o'clock. My classes finish at five o'clock. After school, I go home. It is a very busy day.

Error analysis:
error_sentence: I can very busy on Monday.
correct_sentence: I am very busy on Monday.
error: can
correction: am
error_type: Auxiliary Error
error_severity: 2
error_description: Auxiliary Error: According to English grammar rules, 〈can〉 is a modal verb indicating ability or possibility and cannot directly modify an adjective to form a predicative structure. A linking verb is needed here to connect the adjective and express a state. Therefore, 〈can very busy〉 is changed to the first-person linking verb 『am』, forming the correct subject-linking verb-predicate structure 『I am very busy』 to accurately describe the state of 'being busy on Monday'. This correction conforms to the basic grammatical norm of pairing linking verbs with adjectives in English.
error_sentence: Then at seven o'clock, I have beakfast.
correct_sentence: Then at seven o'clock, I have breakfast.
error: beakfast
correction: breakfast
error_type: Spelling Error
error_severity: 2

error: finsh
correction: finish
error_type: Spelling Error

error: wear
correction: wears
error_type: Subject-Verb Agreement Error
error_severity: 3
error_description: Subject-Verb Agreement Error: According to English third-person singular rules, the subject 〈My classmate〉 is singular, so its present tense verb needs an -s. Therefore, the base form verb 〈wear〉 is changed to the third-person singular form 『wears』 to ensure strict subject-verb agreement in number.
error_sentence: My classmate wear a blue shirt, and pure white shoes.
correct_sentence: My classmate wears a blue shirt and pure white shoes.
error: ,
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English punctuation rules for parallel structures, when the coordinating conjunction 〈and〉 connects two grammatically equivalent noun phrases, no 〈,〉 is needed in between. Therefore, the redundant 〈,〉 is deleted to make the structure conform to the principle of conciseness in English.
error_sentence: I like with hers play.
correct_sentence: I like to play with her.
error: with hers play
correction: to play with her
error_type: Word Order Error
error_severity: 5
error_description: ① Word Order Error: According to the standard English word order "verb + preposition + object," the misplaced phrase 〈with hers play〉 is adjusted to the grammatically logical 『to play with her』 to ensure the sentence is smooth and natural; ② Nonfinite Verb Form Error: According to the English grammar rule for using infinitives as adverbials of purpose, the verb 〈play〉 needs to be changed to the infinitive form with 'to', 『to play』, to correctly express the purpose of the action; ③ Pronoun Error: According to the English usage rule for objective case pronouns, the preposition with should be followed by an objective pronoun, so the possessive pronoun 〈hers〉 is changed to the objective form 『her』.

correction: to take
error_type: Nonfinite Verb Form Error
error_severity: 4
error_description: ① Punctuation Error: 〈Take care of my doll〉 is incorrectly separated from the preceding sentence by a period and lacks a subject; it should be connected using an infinitive, so the 〈.〉 should be removed; ② Nonfinite Verb Form Error: The infinitive 『to take』 is needed to combine the two actions into a complex adverbial of purpose, reflecting the continuity of going home to take care of the doll.

error_type: Pronoun Error
error_severity: 4
error_description: ① Noun Number Error: According to English grammar rules, when referring to clothing or other countable nouns, especially when referring to a category of items or multiple items in general, the plural form is usually used; therefore, 〈shirt〉 is changed to the plural form 『shirts』 to match the general reference to wearing habits mentioned earlier; ② Space Error: According to English writing conventions, a period is a punctuation mark that immediately follows a word, the space here is redundant; therefore, the space between 〈shirt〉 and 〈.〉 is deleted to conform to the convention; ③ Pronoun Error: 〈My〉 is a possessive pronoun and cannot be used as a subject. In English, the nominative pronoun 『I』 should be used to indicate the performer of the action; therefore, 〈My〉 is changed to 『I』 to conform to sentence structure and grammatical rules.

error_description: ① Subject-Verb Agreement Error: According to English grammar rules, when the subject is third-person singular (like 〈He〉), the present tense verb needs to be in the third-person singular form. In the original sentence, 〈like〉 is not in the third-person singular form, which is a subject-verb agreement error; it should be changed to 『likes』; ② Nonfinite Verb Form Error: When 'like' is followed by a verb, the structure 'like to do sth.' is commonly used. In the original sentence, 〈wear〉 is not in the infinitive form, which violates grammatical rules; it should be changed to 『to wear』 to make the sentence grammatically correct; ③ Determiner Error: In English, singular countable nouns (like 〈shirt〉) often require an indefinite article when used generically. The original sentence lacks an indefinite article before 〈shirt〉; 『a』 should be added to conform to English expression habits.
error_sentence: He like wear beautiful blue shirt and pure white shoes ever day

error: he wear
correction: He wears
error_type: Subject-Verb Agreement Error
error_severity: 3
error_description: ① Case Error: According to English writing conventions, the first letter of a sentence must be capitalized; therefore, the pronoun 〈he〉 is corrected to the capitalized form 『He』 to meet proper English punctuation and formatting requirements; ② Subject-Verb Agreement Error: According to English grammar rules, the subject 〈he〉 is third-person singular, requiring the verb to be in its corresponding singular form; thus, the base verb 〈wear〉 is changed to the third-person singular form 『wears』 to ensure subject-verb agreement.
error_sentence: he wear a blue shirt and the white beautiful shoes.
correct_sentence: He wears a blue shirt and beautiful white shoes.
error: the white beautiful
correction: beautiful white
error_type: Word Order Error
error_severity: 5
error_description: ① Determiner Error: Based on the context, this does not refer to a specific pair of shoes; therefore, the unnecessary definite article 〈the〉 is deleted to make the expression better fit a general context; ② Word Order Error: According to English adjective order rules, opinion adjectives (like 〈beautiful〉) should precede descriptive adjectives (like 〈white〉); therefore, the incorrectly ordered 〈white beautiful〉 is adjusted to the grammatically conventional 『beautiful white』.
error_sentence: He like hjs shoes very much.
correct_sentence: He likes his shoes very much.
error: like hjs
correction: likes his
error_type: Subject-Verb Agreement Error
error_severity: 4
error_description: ① Subject-Verb Agreement Error: According to English grammar rules, the subject 〈He〉 is third-person singular, requiring the verb to be in its corresponding singular form; thus, the base verb 〈like〉 is changed to the third-person singular form 『likes』 to ensure subject-verb agreement; ② Spelling Error: According to English spelling rules, 〈hjs〉 does not conform to the structure of any English word; the correct form should be the possessive pronoun 『his』.

Error analysis:
error_sentence: He only Watchs them on TV.
correct_sentence: He only watches them on TV.
error: Watchs
correction: watches
error_type: Spelling Error
error_severity: 3
error_description: ① Spelling Error: According to English verb conjugation rules, when the subject is third-person singular, verbs ending in -ch like 〈watch〉 require the suffix -es to form the correct form, therefore the incorrect spelling 〈Watchs〉 is corrected to 『watches』 to meet the morphological requirement for the third-person singular; ② Case Error: According to English writing conventions, words within a sentence that are not proper nouns or the first word should not be capitalized, thus the incorrect capitalized form 〈Watchs〉 is corrected to the lowercase form 『watches』 to ensure compliance with English capitalization rules. Both errors need simultaneous correction, resulting in the standard form 『watches』.
error_sentence: He has twofriends, Mike and Dave.
correct_sentence: He has two friends, Mike and Dave.
error: twofriends
correction: two friends
error_type: Space Error
error_severity: 1
error_description: Space Error: According to English writing conventions, when the cardinal number 〈two〉 is used with the common noun 〈friends〉 to form a quantity phrase, a space must separate them to maintain clear word boundaries. Therefore, the incorrectly joined form 〈twofriends〉 is corrected to the standard writing 『two friends』, ensuring both the accuracy of the quantity expression and compliance with the basic rules of spacing between words in English.
error_sentence: He thinks it's diffcult.

error_type: Spelling Error

Error analysis:
error_sentence: Gao fong is a football fan.
correct_sentence: Gao Feng is a football fan.
error: fong
correction: Feng
error_type: Spelling Error
error_severity: 2
error_description: ① Spelling Error: According to Pinyin transcription rules, the second character in the Chinese name 〈Gao fong〉 is misspelled. The original spelling 〈fong〉 does not conform to standard Pinyin; the correct spelling should be 『Feng』; ② Case Error: According to English name capitalization rules, the first letter of the name should be capitalized, thus the overall correction is 『Gao Feng』.
error_sentence: He only watch football.
correct_sentence: He only watches football.
error: watch
correction: watches
error_type: Subject-Verb Agreement Error
error_severity: 3
error_description: Subject-Verb Agreement Error: According to English subject-verb agreement rules, when the subject is 〈He〉, the verb must be in the third-person singular form. The verb 〈watch〉 in the original sentence is in the base form, violating the agreement principle, so it is corrected to the third-person singular form 『watches』.
error_sentence: He has two friend, Mike and Dave.
correct_sentence: He has two friends, Mike and Dave.
error: friend
correction: friends
error_type: Noun Number Error
error_severity: 2
error_description: Noun Number Error: According to English quantifier modification rules, the cardinal number 〈two〉 must be followed by a plural countable noun. The singular noun 〈friend〉 in the original sentence does not match the quantifier, so it is corrected to the plural form 『friends』 to express the plural concept.

This is a ...
What colour is it? It's...
Its ... is/are...

Student essay:
This is a rabit. It's very cute. What color is it? oh, it's white. It's like eating grass.

Corrected essay:
This is a rabbit. It's very cute. What color is it? Oh, it's white. It likes eating grass.

Error analysis:
error_sentence: This is a rabit.
correct_sentence: This is a rabbit.
error: rabit
correction: rabbit
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: According to English spelling norms, 〈rabit〉 has an incorrect letter order; the correct spelling is 『rabbit』. This error involves improper application of the consonant doubling rule; note that in a closed syllable structure between 〈b〉 and 〈i〉, the consonant 〈b〉 should be doubled, while the final voiceless consonant 〈t〉 remains single.
error_sentence: oh, it's white.
correct_sentence: Oh, it's white.
error: oh
correction: Oh
error_type: Case Error
error_severity: 1
error_description: Case Error: According to English writing conventions, the interjection 〈oh〉 at the beginning of a sentence must follow the rule of capitalizing the first letter; therefore, the lowercase form 『oh』 is changed to the capitalized form 『Oh』 to maintain sentence structure formality. This correction also aligns with the grammatical requirement that interjections used independently in English must be capitalized.
error_sentence: It's like eating grass.
correct_sentence: It likes eating grass.
error: 's like
correction: likes
error_type: Word Redundancy Error
error_severity: 3
error_description: ① Word Redundancy Error: According to English grammar rules, the contraction 〈's〉 in 〈It's like〉 is the abbreviation for 〈is〉, changing the sentence meaning to 'it is like eating grass' (indicating comparison), which deviates semantically from the intended meaning 'it likes eating grass' (indicating preference). Therefore, 〈is〉 should be removed, leaving only the subject 〈It〉; ② Subject-Verb Agreement Error: According to English grammar rules, the subject 〈It〉 is third-person singular, requiring the verb to be in its singular form. The original sentence uses the base form 〈like〉, which violates the subject-verb agreement principle; it should be corrected to the third-person singular form 『likes』 to make the sentence structure complete and grammatically correct.

error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English writing conventions, the original clause 〈I have many classmates〉 and the phrase 〈my best friend Amy〉 are treated as parts of run-on sentences; however, they contain independent subject-verb structures or represent complete thoughts that should form separate sentences. Also, according to English writing conventions, the first letter of a sentence should be capitalized, so 〈, my...〉 needs to be changed to 〈. My...〉 to form two separate sentences.
error_sentence: I have many classmates, my best friend Amy, she wear a beautiful shirt
correct_sentence: My best friend is Amy. She wears a beautiful shirt.
error: Amy, she wear
correction: is Amy. She wears
error_type: Sentence Structure Error
error_severity: 4
error_description: ① Sentence Structure Error: According to English syntax rules, the clause 〈My best friend Amy〉 lacks a predicate verb; the third-person singular present tense form of the be-verb 『is』 needs to be added before 〈Amy〉 to make the sentence structure complete; ② Punctuation Error: The original clauses 〈My best friend is Amy〉 and 〈she wear a beautiful shirt〉 contain independent subject-verb structures and can stand alone as sentences, so 〈, she...〉 needs to be changed to 『. She...』 to form two separate sentences; ③ Subject-Verb Agreement Error: The third-person singular subject 〈She〉 requires the third-person singular form of the predicate verb, therefore the base form of the verb 〈wear〉 needs to be changed to the third-person singular present tense form 『wears』 to conform to the principle of subject-verb agreement.
error_sentence: I have many classmates, my best friend Amy, she wear a beautiful shirt
correct_sentence: She wears a beautiful shirt.
correction: .
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English syntax rules, the end of an independent sentence needs to be marked with an appropriate punctuation mark to indicate the sentence's conclusion, therefore the original sentence is missing a period at the end; there is a missing punctuation error here. A 『.』 needs to be added after 〈shirt〉 to mark the end of the sentence to comply with English syntax rules.

Error analysis:
error_sentence: On saturday, he is going to do his homework at 9:30 in the morning.
correct_sentence: On Saturday, he is going to do his homework at 9:30 in the morning.
error: saturday
correction: Saturday
error_type: Case Error
error_severity: 1
error_description: Case Error: According to English writing conventions, the day name 〈saturday〉 is a proper noun and must be capitalized; therefore, the lowercase form 〈saturday〉 is corrected to the standard form 『Saturday』 to maintain the correct writing format for proper nouns.
error_sentence: He is going to relax by watching TV at 1:00.
correct_sentence: He is going to relax by watching TV at 11:00 a.m.
error: 1:00.
correction: 11:00 a.m.
error_type: Noun Error
error_severity: 3
error_description: ① Number Error: Based on the contextual time logic, the prompt specifies Tom's TV time as 『11:00』 in the morning, but the original sentence incorrectly uses 〈1:00〉, causing a contradiction in time description. Therefore, the incorrect number 〈1:00〉 should be corrected to the required 『11:00』 to maintain accurate time information; ② Noun Error: According to English time expression conventions, the numerical time 〈11:00〉 requires a time period identifier. Since this time is in the morning, the Latin abbreviation 『a.m.』 needs to be added to form the complete time expression 『11:00 a.m.』, which avoids ambiguity and meets formal writing requirements.
error_sentence: In the aftenoon, he is going to the park with his friends!
correct_sentence: In the afternoon, he is going to the park with his friends!
error: aftenoon
correction: afternoon
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: According to English word formation rules, 〈aftenoon〉 is misspelled; the correct spelling should be 『afternoon』, expressing the concept of 'afternoon'. The misspelled 〈aftenoon〉 is corrected to the standard spelling form 『afternoon』 to comply with the standard writing requirements for English words.
