Writing hints: wear; shirt; shoes; beautiful; like

Student essay:

Corrected essay:
Look! This is my classmate. He wears a blue shirt and red shoes. I think they are beautiful. He likes them very much.

Error analysis:
error_sentence: This is my clossmate.
correct_sentence: This is my classmate.
error: clossmate
correction: classmate
error_type: Spelling Error
error_severity: 1
error_description: Spelling Error: According to the sentence meaning, the word 〈clossmate〉 expresses the meaning 'classmate', therefore 〈clossmate〉 is a spelling error for 『classmate』, so it needs to be changed from 〈clossmate〉 to 『classmate』.
error_sentence: He wear a blue shirt and red shoes.
correct_sentence: He wears a blue shirt and red shoes.
error: wear
correction: wears
error_type: Subject-Verb Agreement Error
error_severity: 2
error_description: Subject-Verb Agreement Error: According to English grammar rules, when the subject is third-person singular, the predicate verb should also be in the third-person singular form. The subject 〈He〉 in the original sentence is third-person singular, while the predicate verb 〈wear〉 is the base form, therefore 〈wear〉 needs to be changed to 『wears』 to satisfy the principle of subject-verb agreement.
error_sentence: He is very like them
correct_sentence: He likes them very much.
error: is very like them
correction: likes them very much.
error_type: Word Redundancy Error
error_severity: 5
error_description: ① Word Redundancy Error: According to English grammar, a complete subject-predicate structure cannot use two predicate verbs simultaneously; the original phrase 〈is like〉 uses two verbs, so the redundant verb 〈is〉 should be deleted, and the base form verb 〈like〉 should be changed to the third-person singular form 『likes』 to maintain subject-verb agreement; ② Word Order Error: According to English grammar, the adverb of degree 〈very〉 is generally placed after the verb and needs to be followed by 『much』 to form the fixed phrase 『very much』, therefore 〈very like〉 needs to be adjusted to 『likes...very much』.

Error analysis:
error_sentence: At 7:00 P.M.Linda is helping mother do housework
correct_sentence: At 7:00 P.M. Linda is helping her mother do housework.
error: P.M.Linda
correction: P.M. Linda
error_type: Space Error
error_severity: 1
error_description: ① Space Error: According to English writing conventions, a space is required after the time abbreviation 〈P.M.〉 to separate it from the following content; the original phrase 〈P.M.Linda〉 lacks a space and should be changed to 『P.M. Linda』 to conform to English writing conventions.
error_sentence: At 7:00 P.M.Linda is helping mother do housework
correct_sentence: At 7:00 P.M. Linda is helping her mother do housework.
correction: her
error_type: Determiner Error
error_severity: 2
error_description: ① Determiner Error: Based on the sentence meaning, the intention is to express “helping her mother”; the original phrase 〈helping mother〉 lacks a possessive pronoun; 『her』 should be added before the singular countable noun 〈mother〉, changing it to 『helping her mother』 to clarify possession and comply with countable noun usage rules.
error_sentence: At 7:00 P.M.Linda is helping mother do housework
correct_sentence: At 7:00 P.M. Linda is helping her mother do housework.
correction: .
error_type: Punctuation Error
error_severity: 2
error_description: ① Punctuation Error: According to English writing conventions, a sentence must end with punctuation to indicate structural completeness. The original sentence 〈At 7:00 P.M.Linda is helping mother do housework〉 lacks a period at the end, which is a punctuation error. Therefore, a 『.』 needs to be added at the end of the sentence to comply with English writing conventions.

Student essay:
It's three p.m.In the supermaket. A little girl is buying some food. A young lady is looking at a dress. Linda's mother is trying the shoes. Linda's father is staying on the sofa. He is waiting for.

Corrected essay:
It's three p.m. in the supermarket. A little girl is buying some food. A young lady is looking at a dress. Linda's mother is trying on the shoes. Linda's father is staying on the sofa. He is waiting for Linda's mother.

Error analysis:
error_sentence: It's three p.m.In the supermaket.
correct_sentence: It's three p.m. in the supermarket.
error: In the supermaket
correction: in the supermarket
error_type: Spelling Error
error_severity: 4
error_description: ① Space Error: According to English syntax rules, when the time expression 〈p.m.〉 is in a sentence, a space is needed after it to separate it from the following word, so 〈p.m.〉 should be changed to 『p.m. 』; ② Case Error: According to English syntax rules, the first letter of a preposition in the middle of a sentence does not need to be capitalized, so 〈In〉 after 『p.m. 』 should be changed to lowercase 『in』; ③ Spelling Error: According to the sentence's meaning, it refers to a “supermarket”; the correct English spelling is “supermarket”, so 〈supermaket〉 needs to be corrected to 『supermarket』 to conform to English spelling norms.
error_sentence: Linda's mother is trying the shoes.
correct_sentence: Linda's mother is trying on the shoes.
correction: on
error_type: Preposition Error
error_severity: 2
error_description: Preposition Error: According to the sentence's meaning and the prompt's requirement, the intended expression is “Linda's mother is trying on the shoes”. The English phrasal verb “try on something” means “to put on (clothing) to see if it fits”, which is a fixed phrase. Here, “the shoes” corresponds to “something”, so the preposition 『on』 needs to be added after 〈trying〉 to form 『trying on』, conforming to the English fixed phrase.
error_sentence: He is waiting for.
correct_sentence: He is waiting for Linda's mother.
correction: Linda's mother
error_type: Pronoun Error
error_severity: 3
error_description: Pronoun Error: According to English grammar rules, the phrasal verb 〈wait for〉 must be followed by a specific object to indicate who is being waited for. Here, the “object being waited for” is “Linda's mother”, so 『Linda's mother』 needs to be added after 〈waiting for〉 to make the meaning complete and conform to English grammar rules.

Corrected essay:
Mr. Cool's Clothes Store is having a sale. The clothes are very cheap. All kinds of sweaters are only 30 yuan. Shorts are also 20 yuan. You can spend 25 yuan to buy a shirt.

Error analysis:
error_sentence: Mr. Cool's Clothes Store is selling. They are very cheap.
correct_sentence: Mr. Cool's Clothes Store is having a sale. The clothes are very cheap.
error: selling. They
correction: having a sale. The clothes
error_type: Verb Choice Error
error_severity: 4
error_description: ① Verb Choice Error: According to the prompt, expressing that the store is having a big sale should use “having a sale”; “selling” only indicates general sales activity. The original phrase 〈is selling〉 does not accurately convey the context of a “big sale” and needs to be changed to 『is having a sale』 to express the meaning accurately; ② Pronoun Error: Based on the context, the referent of 〈They〉 is unclear (the previous subject was the store), while this sentence needs to clearly refer to the promotional items, so 〈They〉 should be changed to 『The clothes』 for clear reference.
error_sentence: All kinds of swearter are only 30 yuan.
correct_sentence: All kinds of sweaters are only 30 yuan.
error: swearter
correction: sweaters
error_type: Noun Number Error
error_severity: 3
error_description: ① Noun Number Error: According to English grammar rules, “all kinds of” should be followed by a plural noun when the noun is countable; the original word 〈sweater〉 is singular and should be changed to 『sweaters』; ② Spelling Error: According to English spelling rules, and considering the context requires the plural form “sweaters”, 〈swearter〉 is not correctly spelled as the plural form 『sweaters』; 〈swearter〉 needs to be corrected to 『sweaters』 to conform to correct English spelling rules.
error_sentence: You can spend 25 yuan to buy shirt.
correct_sentence: You can spend 25 yuan to buy a shirt.
correction: a
error_type: Determiner Error
error_severity: 2
error_description: ① Determiner Error: According to English grammar rules, a singular countable noun must be preceded by a determiner. In the original sentence, 〈shirt〉 is a singular countable noun, and it lacks a determiner before it, which is a determiner error. “shirt” begins with a consonant sound, requiring the addition of the indefinite article 『a』. Therefore, 〈buy shirt〉 in the original sentence should be changed to 『buy a shirt』 to comply with English grammar rules.

Error analysis:
error_sentence: What colour is this?
correct_sentence: What colour is it?
error: this
correction: it
error_type: Pronoun Error
error_severity: 3
error_description: Pronoun Error: According to the context, the demonstrative pronoun 〈this〉 means 'this', which is unclear in this context; the pronoun 『it』 should be used to refer back to the previously mentioned rabbit. Therefore, 〈What colour is this〉 is changed to 『What colour is it』 to maintain referential consistency.
error_sentence: It's whire.
correct_sentence: It's white.
error: whire
correction: white
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: According to the sentence meaning, the intended word is 'white', therefore 〈whire〉 is a misspelling of 『white』; it needs to be corrected to 『white』 for the sentence to make sense.
error_sentence: Its ears is a long.
correct_sentence: Its ears are long.
error: is a
correction: are
error_type: Determiner Error
error_severity: 3
error_description: ① Subject-Verb Agreement Error: The subject 〈ears〉 is plural, according to the subject-verb agreement principle, the singular verb form 〈is〉 should be changed to the plural form 『are』; ② Determiner Error: According to English grammar rules, the indefinite article 〈a〉 is not needed before the adjective 〈long〉, therefore the redundant determiner 〈a〉 needs to be deleted to conform to English expression habits.

error_sentence: The weekends will going.
correct_sentence: The weekend is coming.
error: weekends will going
correction: weekend is coming
error_type: Noun Number Error
error_severity: 4
error_description: ① Noun Number Error: 〈weekends〉 is plural, meaning multiple weekends, but the context refers to "this weekend", so the singular form 『weekend』 should be used; ② Auxiliary Error: The phrase 〈will going〉 incorrectly combines the simple future tense structure "will go" and the present continuous for future "is going"; choosing the latter, the auxiliary verb should be changed to 『is』; ③ Verb Choice Error: According to the prompt's meaning, the weekend is approaching, so the verb should be "come", not "go".
error_sentence: On Saturday, I will study in home with my mom.
correct_sentence: On Saturday, I will study at home with my mom.
error: in
correction: at
error_type: Preposition Error
error_severity: 3
error_description: Preposition Error: According to standard English expression, the fixed phrase for "at home" is 『at home』, not 〈in home〉, so the preposition 〈in〉 needs to be changed to 『at』.
error_sentence: And i will have a good time in the park with my friends.
correct_sentence: And I will have a good time in the park with my friends.
error: i
correction: I
error_type: Case Error

error_sentence: This is my weekends plan.
correct_sentence: This is my weekend plan.
error: weekends
correction: weekend
error_type: Noun Number Error
error_severity: 3
error_description: Noun Number Error: According to English rules, when a noun functions as an attributive, it usually takes the singular form; therefore, 〈weekends〉 used as an attributive modifying 〈plan〉 needs to be in the singular form, changing it to 『weekend』.

correction: Tian'anmen
error_type: Determiner Error
error_severity: 4
error_description: ① Spelling Error: According to English spelling conventions, the proper noun "Tian'anmen" 〈Tisn'anme〉 has incorrect letter order; the correct spelling should be 『Tian'anmen』; ② Determiner Error: According to English grammar rules, the proper place name 〈Tian'anmen Square〉 does not require the definite article 〈the〉 before it; therefore, the redundant determiner needs to be deleted to conform to English grammar rules.
error_sentence: I like eating Beijing Roast Duck, so I go to Beijing eat Beijing Roast Duck with my mother and my father.
correct_sentence: I like eating Beijing Roast Duck, so I will go to Beijing to eat Beijing Roast Duck with my mother and my father.

error_severity: 3
error_description: Verb Tense Error: According to the context, the original text describes the "plan to visit Beijing over the summer"; according to English grammar rules, the simple future tense is needed to describe future plans; there is a verb tense error here, so 〈go〉 needs to be changed to 『will go』 to conform to the context and English grammar rules.

error_severity: 3
error_description: Nonfinite Verb Form Error: According to the sentence meaning, the intention here is to express "the purpose of going to Beijing is to eat Beijing Roast Duck"; according to English grammar rules, the infinitive 'to do' is needed to express purpose; there is a nonfinite verb error here, so 〈eat〉 needs to be changed to 『to eat』 to conform to the sentence meaning and English grammar rules.

error_severity: 3
error_description: Nonfinite Verb Form Error: According to English grammar rules, when the verb 〈invited〉 is followed by the object 〈his friends〉, the infinitive structure 『to come』 is required as the object complement; therefore, 『to』 is added to form the correct 'invite sb. to do sth.' structure.

error: my
correction: Jack's
error_type: Pronoun Error

Writing prompt: Lucy's grandmother is telling her about life several years ago. The environment where she lived has changed significantly. Using the provided hints and sentence patterns, write a short English essay about these changes.
Writing hints: different; flats; fields; bushes; buildings.
Reference sentence patterns: There was/were... ; There wasn't/weren't any... ; There was/were no...

Student essay:
There was different with now. There weren't any flats and building. There were some fields and bushes. The sky was blue and the air was fresh.

Corrected essay:
It was different from now. There weren't any flats or buildings. There were some fields and bushes. The sky was blue and the air was fresh.

Error analysis:
error_sentence: There was different with now.
correct_sentence: It was different from now.
error: There
correction: It
error_type: Pronoun Error
error_severity: 3
error_description: Pronoun Error: According to English comparative sentence structure rules, the existential sentence 〈There was〉 cannot introduce a comparison. When expressing the comparative relationship 'A is different from B', the formal subject 『It』 must be used to construct the correct sentence pattern. Therefore, 〈There〉 should be replaced with 『It』 to form the standard comparative structure 『It was different...』, complying with English subject usage norms.
error_sentence: There was different with now.
correct_sentence: It was different from now.
error: with
correction: from
error_type: Preposition Error
error_severity: 2
error_description: Preposition Error: The adjective 〈different〉 requires a fixed prepositional collocation in English; it must be used with 『from』 to indicate difference. The original sentence's use of 〈with〉 is a common preposition misuse. 〈with〉 should be corrected to 『from』 to form the standard collocation 『different from』, ensuring the expression conforms to English usage.
error_sentence: There weren't any flats and building.
correct_sentence: There weren't any flats or buildings.
error: and building
correction: or buildings
error_type: Conjunction Error
error_severity: 4
error_description: ① Conjunction Error: According to the rules for parallel structures in negative sentences in English grammar, in a negative structure like 〈There weren't any〉, multiple parallel elements must be connected using 『or』, not 〈and〉. Using 〈and〉 in the original sentence creates a logical conflict with the negative meaning. Therefore, 〈and〉 needs to be replaced with 『or』 to form the correct negative parallel structure 『There weren't any flats or buildings』, accurately conveying the complete negative semantics; ② Noun Number Error: According to the usage rules for countable nouns in negative sentences in English, when 〈building〉 is used as a countable noun in a general sense, it must take the plural form after the negative structure 〈any〉. The use of the singular 〈building〉 in the original sentence does not meet the grammatical requirements for negative sentences and should be changed to the plural form 『buildings』, forming the standard negative expression 『any buildings』 to ensure the noun form is consistent with the negative context.
Writing prompt: Write a short essay titled "My next weekend." Based on the picture information, use the future tense (be going to) to introduce your plans for next weekend.

Error analysis:
error_sentence: Next weekend, I'm going to visit my grandparents's home.
correct_sentence: Next weekend, I'm going to visit my grandparents' home.
error: 's
correction: '
error_type: Noun Possessive Error
error_severity: 2
error_description: Noun Possessive Error: According to the rules for forming noun possessives in English grammar, for plural nouns ending in 's' like 〈grandparents〉, the possessive form is made by simply adding an apostrophe 〈'〉 at the end. Therefore, the incorrect form 〈grandparents's〉 is corrected to the proper form 『grandparents'』 to comply with the standard formation of plural noun possessives in English.
error_sentence: After visit, I'm going to help my mother do housework.
correct_sentence: After the visit, I'm going to help my mother do housework.
correction: the
error_type: Determiner Error
error_severity: 3
error_description: Determiner Error: According to English grammar rules, when the noun 〈visit〉 refers to a specific, singular instance of visiting, it requires the definite article 〈the〉 for specification. Therefore, the definite article 『the』 is added to the prepositional phrase 〈After visit〉, changing it to 『After the visit』, to align with the grammatical norm of using the definite article to specify a particular activity.
error_sentence: In the afternoon, I'm play computer games and play football.
correct_sentence: In the afternoon, I'm going to play computer games and play football.
correction: going to
error_type: Verb Tense Error
error_severity: 3
error_description: Verb Tense Error: According to the rules for forming the simple future tense in English grammar, the 'be going to' structure requires the complete form 'be verb + going to + base form of the verb'. The original sentence 〈I'm play〉 has a missing structure; it needs the addition of 『going to』 while keeping the base verb form. Thus, it is corrected to 『I'm going to play』 to conform to the correct expression of the future tense.
Writing prompt: Based on what you learned in this unit and the provided hints, use colors to describe your classmate's attire.

error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English compound sentence writing rules, 〈Today I wear a pure white shirt, it's pretty〉 contains two complete independent clauses that cannot be joined solely by a comma; therefore, the comma 〈,〉 is changed to a period 『.』 and the sentence is split to avoid a grammatical error.
error_sentence: I wear shoes are pink, it's lovely.
correct_sentence: I wear shoes that are pink.
correction: that
error_type: Relative Word Error
error_severity: 3
error_description: Relative Word Error: According to English relative clause grammar rules, when the descriptive relative clause 〈are pink〉 modifies the noun 〈shoes〉, the relative pronoun 『that』 must be used as the connective word; therefore, the incomplete structure 〈shoes are pink〉 is modified to the complete relative clause 『shoes that are pink』 to comply with English compound sentence grammar requirements while maintaining the original meaning 'the shoes are pink'.
error_sentence: I wear shoes are pink, it's lovely.
correct_sentence: I wear shoes that are pink. They're lovely.
error: , it's
correction: . They're
error_type: Pronoun Error
error_severity: 3
error_description: ① Punctuation Error: According to English coordinate clause rules, 〈I wear shoes that are pink, it's lovely〉 contains two complete main clauses that cannot be joined solely by a comma; therefore, the comma 〈,〉 is changed to a period 『.』 and the sentence is split to avoid a grammatical error; ② Pronoun Error: According to English pronoun reference rules, the plural noun 〈shoes〉 requires a plural pronoun for reference; therefore, the singular pronoun 'it' is changed to the plural form 'They' to ensure consistent reference; ③ Subject-Verb Agreement Error: The subject and verb in the sentence must agree, so the verb should change from 'is' to 'are', and the contracted form changes from 〈it's〉 to 『They're』.
error_sentence: I like myshirt and shoes.
correct_sentence: I like my shirt and shoes.
error: myshirt
correction: my shirt
error_type: Space Error
error_severity: 1
error_description: Space Error: According to English writing conventions, the possessive pronoun 'my' acting as a determiner must be written separately from the noun 'shirt' it modifies, separated by a space; therefore, the joined form 〈myshirt〉 is corrected to the standard form 『my shirt』 to ensure proper word spacing and readability.

Error analysis:
error_sentence: There is my bedroom.

error_type: Pronoun Error
error_severity: 2
error_description: Pronoun Error: According to English grammar rules and context analysis, when directly introducing or presenting a scene/object, the demonstrative pronoun 〈This〉 should be used instead of the existential 〈There〉. The original 〈There〉 only indicates 'existence', while the 『This is』 structure achieves the function of 'presentation'. Therefore, the sentence-initial 〈There〉 is corrected to 『This』 to accurately fulfill the speaker's intention of presentation (e.g., when showing pictures/scenes or specific objects).
error_sentence: There are two bookshelf on the bed.
correct_sentence: There are two bookshelves above the bed.
error: bookshelf on
correction: bookshelves above
error_type: Noun Number Error
error_severity: 3
error_description: ① Noun Number Error: According to the quantitative relationship expressed by the sentence meaning, 〈bookshelf〉 is a singular countable noun, while the context clearly refers to two bookshelves. Therefore, the singular noun 〈bookshelf〉 needs to be changed to the plural form 『bookshelves』 to maintain subject-number agreement; ② Preposition Error: According to spatial description norms, the preposition 〈on〉 indicates placement directly on a surface, whereas the actual context needs to express the spatial relationship of 'suspended above'. Therefore, the preposition of place 〈on〉 is corrected to 『above』 to accurately describe the spatial logic of the bookshelves being directly above the bed.
error_sentence: There is my room.
correct_sentence: This is my room.
error: There
correction: This
error_type: Pronoun Error
error_severity: 2
error_description: Pronoun Error: According to English reference rules and context analysis, 〈There〉 as an introductory word for existential sentences (There is/are) only indicates the existence or location of something, while the current sentence intends to directly introduce a specific room (e.g., when showing a photo of the room or guiding a tour). Therefore, the existential pronoun 〈There〉 is corrected to the demonstrative pronoun 『This』, making the language more suitable for the situational introduction requirement.

error_type: Case Error
error_severity: 1
error_description: ① Case Error: According to English writing conventions, the first letter of the first word in a sentence is capitalized, while other non-proper nouns within the sentence do not need capitalization. In the original sentence, 〈It〉 follows a comma, is not at the beginning of the sentence, and is not a proper noun; this is a capitalization error. Therefore, 〈It〉 needs to be changed to 『it』 to comply with English capitalization rules.
error_sentence: Linda's brother is playing computer.
correct_sentence: Linda's brother is playing computer games.
correction: games
error_type: Noun Error
error_severity: 3
error_description: ① Noun Error: According to the prompt, the complete expression for 'playing computer games' is "play computer games". "Computer" itself is a device; using 〈playing computer〉 alone cannot accurately convey the meaning of 'playing computer games'. It is necessary to add 'games' to clarify the object of the action, meaning playing computer games. The original sentence contains a noun error; 『games』 should be added after 〈computer〉 to make the expression accurate.
error_sentence: Linda's sister is listening to the redio.
correct_sentence: Linda's sister is listening to the radio.
error: redio
correction: radio
error_type: Case Error
error_severity: 2
error_description: ① Spelling Error: According to the sentence's meaning, the intention here is to express 'listening to the radio'. Therefore, 〈redio〉 is a misspelling of 『radio』. It needs to be corrected from 〈redio〉 to 『radio』 to make the sentence coherent.

error_type: Subject-Verb Agreement Error
error_severity: 3
error_description: ① Subject-Verb Agreement Error: According to subject-verb agreement rules, when the subject is third-person singular, the verb needs to be in the corresponding third-person singular form. In the original sentence, the subject 〈He〉 is third-person singular, but the verb 〈like〉 is not in the third-person singular form; this is a subject-verb agreement error. Therefore, 〈like〉 needs to be changed to 『likes』 to comply with grammatical rules.
error_sentence: He have got four football.
correct_sentence: He has got four footballs.
error: have
correction: has
error_type: Subject-Verb Agreement Error
error_severity: 3
error_description: ① Subject-Verb Agreement Error: According to the principle of subject-verb agreement, in the present perfect tense, the subject 〈He〉 is third-person singular, so the auxiliary verb must be in the third-person singular form. In the original sentence, the auxiliary verb 〈have〉 does not follow this rule; 〈have〉 should be changed to 『has』 to maintain subject-verb agreement. ② Noun Number Error: According to English grammar rules, the countable noun 〈football〉 is preceded by the number 〈four〉 and needs to be in the plural form; therefore, 〈football〉 is changed to 『footballs』.
error_sentence: He have got four football.
correct_sentence: He has got four footballs.
error: football
correction: footballs

Error analysis:
error_sentence: My student wears a white shirt and a whie shoes.
correct_sentence: My classmate wears a white shirt and white shoes.
error: student
correction: classmate
error_type: Noun Error
error_severity: 3
error_description: Noun Error: According to the prompt, the description should be about a classmate, but the noun 〈student〉 means 'student'. Based on the context and the prompt, the noun 『classmate』, meaning 'classmate', is more appropriate and accurately describes the subject; therefore, 〈student〉 is changed to 『classmate』 to fit the semantic requirement.
error_sentence: My student wears a white shirt and a whie shoes.
correct_sentence: My classmate wears a white shirt and white shoes.
error: a whie
correction: white
error_type: Determiner Error
error_severity: 2
error_description: ① Determiner Error: The plural noun 〈shoes〉 should not be preceded by the singular article 〈a〉; 〈a〉 needs to be deleted. The correction aligns with grammatical rules and semantic logic; ② Spelling Error: Based on the sentence's meaning, the intention is to express 'white', thus 〈whie〉 is a spelling error and needs to be corrected to 『white』.
error_sentence: She is so pretty, I like her clothes
correct_sentence: She is so pretty.
error: ,
correction: .
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English syntax rules, two independent clauses 〈She is so pretty〉 and 〈I like her clothes〉 cannot be connected solely by a comma. A period is needed to separate them for clarity; therefore, 〈,〉 is changed to 『.』 resulting in the sentence 『She is so pretty.』.
error_sentence: She is so pretty, I like her clothes
correct_sentence: I like her clothes.
correction: .
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English writing conventions, the sentence 〈I like her clothes〉 is missing the end punctuation mark, making the sentence structure incomplete; therefore, 『.』 needs to be added, changing it to 『I like her clothes.』 to conform to writing standards.

correction: kinds of sweaters are
error_type: Subject-Verb Agreement Error
error_severity: 4
error_description: ① Noun Number Error: According to English grammar rules, 〈kind〉 is preceded by the quantifier 〈All〉, indicating a plural concept, so the singular noun 〈kind〉 should be changed to the plural noun 『kinds』; ② Noun Number Error: Based on the context, the item name 〈sweater〉 needs its plural form in this context to represent multiple sweaters, so the singular countable noun 〈sweater〉 is changed to the plural noun 『sweaters』 to accurately express the quantity concept; ③ Subject-Verb Agreement Error: Based on the subject 『All kinds of sweaters』, the following verb should be plural to maintain subject-verb agreement, so 〈is〉 needs to be changed to the plural form 『are』 to maintain number consistency.
error_sentence: Short is only 20 yuan.
correct_sentence: Shorts are only 20 yuan.
error: Short is
correction: Shorts are
error_type: Subject-Verb Agreement Error
error_severity: 3
error_description: ① Noun Number Error: Based on the context, the item name 〈short〉 should refer to multiple pairs of shorts rather than a specific one, requiring the plural form for generic reference, so the singular countable noun 〈short〉 is changed to the plural noun 『shorts』 for logical expression. ② Subject-Verb Agreement Error: According to English grammar rules, the subject 『shorts』 is plural, but the verb 〈is〉 does not agree with the plural subject, so 〈is〉 needs to be changed to 『are』 to maintain subject-verb agreement.

correct_sentence: T-shirts are only 25 yuan.
error: shirt is
correction: shirts are
error_type: Subject-Verb Agreement Error
error_severity: 3
error_description: ① Noun Number Error: According to English grammar rules, the noun 〈T-shirt〉 is singular, but the sentence clearly expresses the concept of multiple T-shirts, so the singular countable noun 〈T-shirt〉 should be changed to the plural form 『T-shirts』 to correctly express the quantity relationship; ② Subject-Verb Agreement Error: According to the principle of subject-verb agreement, the subject 〈T-shirt〉 is singular, but the actual context requires the plural form 『T-shirts』, therefore the singular verb 〈is〉 needs to be changed to the plural form 『are』, so that the subject 『T-shirts』 and the verb 『are』 agree in number.
