Error analysis:
error_sentence: This is my parent.
correct_sentence: These are my parents.
error: This is my parent
correction: These are my parents
error_type: Subject-Verb Agreement Error
error_severity: 4
error_description: ① Pronoun Error: The pronoun 〈This〉 is singular, while 『parents』 is plural, thus it needs to be changed to the pronoun 『These』 to match the plural noun; ② Subject-verb Agreement Error: Since the subject 『These』 refers to a plural noun, the be verb should use the plural form, thus changing 〈is〉 to 『are』 to maintain subject-verb agreement; ③ Noun Number Error: 〈parent〉 is the singular form, but according to the following sentence 〈They works at school〉, the meaning refers to the plural parents, thus 〈parent〉 needs to be changed to 『parents』.
error_sentence: They works at school.
correct_sentence: They work at school.
error: works
correction: work
error_type: Subject-Verb Agreement Error
error_severity: 3
error_description: Subject-verb Agreement Error: The subject 〈They〉 is a plural personal pronoun, referring to 〈parents〉 in the previous sentence; here 〈works〉 is the third-person singular form of the predicate verb, which is inconsistent with the subject 〈they〉, therefore 〈works〉 is changed to the plural form 『work』 in the simple present tense to maintain subject-verb agreement.
error_sentence: She is so cult.
correct_sentence: She is so cute.
error: cult
correction: cute
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: The word 〈cult〉 as an adjective means "fanatically revered," which does not match the semantics. According to the context, using the adjective 〈cult〉 to describe 〈my little sister〉 is inappropriate; it is presumed to be a spelling error, therefore 〈cult〉 is modified to 『cute』 to express the characteristic of 〈my little sister〉 being lovely.

Writing hints:
A little girl: buy some food
A young lady: look at a dress
Linda's mother: try on the shoes
Linda's father: stay on the sofa; wait for

Student essay:
I am Linda. Now is 3:00 in the afternoon. My mother is trying the shoes, and my father is staying on the sofa to wait for my mom. In the shop, a litter girl is buying some food, and a young lady is looking at a dress.

Corrected essay:
I am Linda. It is now 3:00 in the afternoon. My mother is trying on the shoes, and my father is staying on the sofa to wait for my mom. In the shop, a little girl is buying some food, and a young lady is looking at a dress.

Error analysis:
error_sentence: Now is 3:00 in the afternoon.
correct_sentence: It is now 3:00 in the afternoon.
error: Now is
correction: It is now
error_type: Sentence Structure Error
error_severity: 4
error_description: Sentence Structure Error: In English time expressions, the correct structure requires 『It』 as a formal subject. The original sentence incorrectly uses 〈Now〉 as the subject in a subject-verb-complement structure. It should be adjusted to 『It is now』 to fulfill the grammatical requirement of a formal subject, with the adverb 'now' modifying the linking verb as a time adverbial, and conforming to the standard English time expression.
error_sentence: My mother is trying the shoes, and my father is staying on the sofa to wait for my mom.
correct_sentence: My mother is trying on the shoes, and my father is staying on the sofa to wait for my mom.
correction: on
error_type: Preposition Error
error_severity: 3
error_description: Preposition Error: According to the prompt, the phrasal verb 『try on』, meaning 'to put on clothes/shoes to see if they fit', is provided as a fixed expression. The original sentence connects 〈try〉 directly with the object 〈the shoes〉, forming the structure 〈trying the shoes〉. This usage might cause semantic ambiguity and does not meet the prompt's requirement. Therefore, the crucial preposition 『on』 needs to be added after 〈trying〉.
error_sentence: In the shop, a litter girl is buying some food, and a young lady is looking at a dress.
correct_sentence: In the shop, a little girl is buying some food, and a young lady is looking at a dress.
error: litter
correction: little
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: Based on the original sentence, the intended meaning is 'a small girl'. Thus, 〈litter〉 in the original sentence is a misspelling. 〈litter〉 as a noun means 'trash; stretcher; a brood of young animals', and as a verb means 'to scatter things untidily'. In contrast, 『little』 is an adjective meaning 'small; young'. The original sentence confused the spelling of these two words, so the correct form should change 〈litter〉 to 『little』.

I'm Tina. I like to listen to music. Because it makes me happy. Linda likes reading story books. Because she has many toys. Jack likes to play basketball. Because he is a sunshine boy.

Error analysis:
error_sentence: I like listen to music.
correct_sentence: I like to listen to music.
correction: to
error_type: Nonfinite Verb Form Error
error_severity: 3
error_description: Nonfinite Verb Form Error: When a verb follows the verb 〈like〉, the infinitive form 'to do' is usually required, not the base form 〈listen〉; 'like to do something' is also a fixed English expression. Thus, there is a nonfinite verb form error here. 〈I like listen〉 should be changed to 『I like to listen』 to comply with English grammar rules.
error_sentence: Becase it makes me happy.
correct_sentence: Because it makes me happy.
error: Becase
correction: Because
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: According to the sentence meaning, the intention here is to express 'because'. The word 〈Becase〉 in the original sentence is misspelled and should be corrected to 『Because』 to conform to standard English spelling rules.
error_sentence: Linda likes read story books.
correct_sentence: Linda likes reading story books.
error: read
correction: reading
error_type: Nonfinite Verb Form Error
error_severity: 3
error_description: Nonfinite Verb Form Error: The verb 〈likes〉 is followed by the gerund form to express a habitual action. Therefore, there is a nonfinite verb form error here. 〈read〉 needs to be changed to 『reading』, forming 『likes reading』 to comply with English grammar rules.
error_sentence: Jack likes play basketball.
correct_sentence: Jack likes to play basketball.
correction: to
error_type: Nonfinite Verb Form Error
error_severity: 3
error_description: Nonfinite Verb Form Error: When a verb follows the verb 〈likes〉, the infinitive form 'to do' is usually required, not the base form 〈play〉. Therefore, there is a nonfinite verb form error here. 〈likes play〉 should be changed to 『likes to play』 to comply with English grammar rules.

error_sentence: My classmate wear beautiful shirt and pink shoes.
correct_sentence: My classmate wears a beautiful shirt and pink shoes.
error: wear
correction: wears a
error_type: Subject-Verb Agreement Error
error_severity: 4
error_description: ① Subject-Verb Agreement Error: In English, when the subject is third-person singular, the present simple verb usually takes an '-s' or '-es' ending (i.e., use the third-person singular form). Here the subject 〈My classmate〉 is singular, therefore using the base form of the verb causes a subject-verb agreement error; 〈wear〉 needs to be changed to the third-person singular form 『wears』; ② Determiner Error: In English, countable nouns require a determiner. Here the noun 〈shirt〉 is a singular countable noun, it needs the article 『a』 before it to mean 'a shirt'.
error_sentence: She like her shirt and shoes are very much.
correct_sentence: She likes her shirt and shoes very much.
error: like
correction: likes
error_type: Subject-Verb Agreement Error

error_description: Subject-Verb Agreement Error: In English, when the subject is third-person singular, the present simple verb usually takes an '-s' or '-es' ending (i.e., use the third-person singular form). Here the subject 〈She〉 is singular, therefore using the base form of the verb 〈like〉 causes a subject-verb agreement error; 〈like〉 needs to be changed to the third-person singular form 『likes』.
error_sentence: She like her shirt and shoes are very much.
correct_sentence: She likes her shirt and shoes very much.
error: are
error_type: Auxiliary Error
error_severity: 3
error_description: Auxiliary Error: One of the basic structures of an English simple sentence is subject-verb-object. The original sentence already has the verb 〈likes〉; using the linking verb 〈are〉 afterwards leads to a sentence structure error. The correct expression is to directly use the verb 〈likes〉 followed by the object; the redundant auxiliary verb 〈are〉 needs to be deleted to conform to the English simple sentence structure.

It is seven o'clock. Linda is helping her mother do housework. Her grandparents are watching TV. Her brother is playing computer games. Her mother is cooking. Her sister is listening to the radio.

Error analysis:
error_sentence: Linda is helping mother do housework.
correct_sentence: Linda is helping her mother do housework.
correction: her
error_type: Pronoun Error
error_severity: 3
error_description: Pronoun Error: Based on the sentence's meaning, it intends to express 'Linda is helping her mother do housework'. As a countable noun, 'mother' cannot stand alone; 『her』 needs to be added to indicate possession, i.e., 'Linda's mother', making the sentence complete.
error_sentence: Her brather is playing computer games.
correct_sentence: Her brother is playing computer games.
error: brather
correction: brother
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: Based on the sentence's meaning, it should be 'brother' 『brother』. The original text has 〈brather〉, which is a spelling error and should be corrected to 『brother』.

correct_sentence: Her mother is cooking.
error: mather
correction: mother
error_type: Spelling Error
error_severity: 2

Error analysis:
error_sentence: It is Seven o'clock.
correct_sentence: It is seven o'clock.
error: Seven
correction: seven
error_type: Case Error
error_severity: 1
error_description: Case Error: The English cardinal number 〈Seven〉 indicating time should be lowercase when not at the beginning of a sentence, thus there is a case error here; it should be changed to 『seven』 to comply with English writing conventions.
error_sentence: I am helping mother doing housework.
correct_sentence: I am helping my mother do housework.
error: mother doing
correction: my mother do
error_type: Pronoun Error
error_severity: 5
error_description: ① Pronoun Error: The subject of this sentence is I, so it refers to 'my mother'; the determiner 『my』 should be added before the noun 〈mother〉 to clarify the possessive relationship; ② Nonfinite Verb Form Error: In English, 'help somebody do sth' is a fixed phrase meaning 'help someone do something', therefore the verb 〈doing〉 should be changed to 『do』 to conform to the fixed English phrase.
error_sentence: My brother is playing computer games My mom is cooking.
correct_sentence: My brother is playing computer games.
correction: .
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: 〈My brother is playing computer games〉 and 〈My mom is cooking〉 are two independent main clauses that need to be separated by a period, thus there is a missing punctuation mark here. A 『.』 should be added before 〈My mom is cooking〉 to comply with English syntax rules.
error_sentence: My sister is listening radio.
correct_sentence: My sister is listening to radio.
correction: to
error_type: Preposition Error
error_severity: 2
error_description: Preposition Error: The verb listen is an intransitive verb and must be followed by the preposition to connect to an object; therefore, 『to』 needs to be added before 〈radio〉 to form the complete phrase 『listen to radio』 to comply with English grammar rules.
Writing prompt: Based on what you learned in this unit and the provided hints, use colors to describe your classmate's attire.
Writing hints: wear; shirt; shoes; beautiful; like

Li Sa's wear black shirt. Li Yiyang's shoes are pink and blue. He's shoes are beautiful I like it

Corrected essay:
Li Sa is wearing a black shirt. Li Yiyang's shoes are pink and blue. His shoes are beautiful. I like them.

Error analysis:
error_sentence: Li Sa's wear black shirt.
correct_sentence: Li Sa is wearing a black shirt.
error: 's wear
correction: is wearing a
error_type: Contraction Error
error_severity: 5
error_description: ① Contraction Error: According to the semantics, this refers to 'Li Sa is wearing a black shirt now'. 〈's〉 indicates noun possessive relationship and is misused as a verb here; therefore, to avoid this contraction error, the predicate verb should be fully spelled out and the present continuous tense 『is wearing』 should be used to express 'Li Sa is wearing a black shirt now'. ② Determiner Error: The countable noun 〈shirt〉 here refers to 'a black shirt' and needs to be in singular form; thus, the countable noun 〈shirt〉 requires a necessary article for limitation. Therefore, adding the indefinite article 『a』 before 〈black shirt〉 conforms to English grammar rules.
error_sentence: He's shoes are beautiful I like it
correct_sentence: His shoes are beautiful.
error: He's
correction: His
error_type: Pronoun Error
error_severity: 3
error_description: Pronoun Error: According to the semantics, this refers to 'his shoes', requiring a possessive pronoun before 〈shoes〉 for limitation. 〈He's〉 is the contraction of 'He is', but a possessive pronoun indicating ownership is needed here; thus, there is a pronoun error, and 〈He's〉 should be changed to 『His』 to modify 〈shoes〉 to fit the semantic and grammatical rules.
error_sentence: He's shoes are beautiful I like it
correct_sentence: His shoes are beautiful.
correction: .
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: The sentences 〈His shoes are beautiful〉 and 〈I like it〉 are two independent main clauses, so they need to be separated by a period; there is a missing punctuation mark here. A period 『. 』 should be added after 〈beautiful〉 to separate them into two complete sentences to conform to English syntactic rules.
error_sentence: He's shoes are beautiful I like it
correct_sentence: I like them.
error: it
correction: them.
error_type: Pronoun Error
error_severity: 3
error_description: Pronoun Error: The pronoun here refers to the preceding plural countable noun 〈shoes〉, so the pronoun must also be in plural form; the pronoun 〈it〉 does not agree in number with the plural noun 〈shoes〉. Thus, there is a pronoun error; the pronoun 〈it〉 should be changed to the plural pronoun 『them』 to maintain consistent reference.
Writing prompt: The weekend is coming. Classmates, what are you planning to do? Using the given vocabulary and sentence patterns, and referring to the picture, write a short essay of about 60 words about your plans for the weekend.
Writing hints: be going to; do cleaning; visit grandparents; have a good time

Student essay:
Come to the weekend. I am going to do cleaning. I am going to visit my grandparents. I am going to fly kite. Have a good time.

Corrected essay:
The weekend is coming. I am going to do cleaning. I am going to visit my grandparents. I am going to fly a kite. I will have a good time.

Error analysis:
error_sentence: Come to the weekend.
correct_sentence: The weekend is coming.
error: Come to the weekend
correction: The weekend is coming
error_type: Sentence Structure Error
error_severity: 4
error_description: ① Sentence Structure Error: According to English expression habits, describing 'something is about to happen' often uses the structure 'subject + be verb + present participle'. The original sentence 〈Come to the weekend〉 is a direct Chinese translation with confused word order and structure, and unclear meaning, so the word order and verb tense should be adjusted to 『The weekend is coming』 to conform to English expression habits.
error_sentence: I am going to fly kite.
correct_sentence: I am going to fly a kite.
correction: a
error_type: Determiner Error
error_severity: 2
error_description: ① Determiner Error: According to English grammar rules, singular countable nouns usually require an appropriate determiner for modification. In the sentence, 〈kite〉 is a singular countable noun, so 『a』 should be added to 〈fly kite〉 to form 『fly a kite』, conforming to English grammar rules.
error_sentence: Have a good time.
correct_sentence: I will have a good time.
error: Have
correction: I will have
error_type: Sentence Structure Error
error_severity: 4
error_description: ① Sentence Structure Error: According to English grammar rules, a complete sentence needs basic components like a subject and a predicate. The original sentence 〈Have a good time〉 only has a predicate verb and an object, lacking a subject, and cannot form a complete subject-predicate structure. Therefore, a subject and corresponding structure should be added, changing it to 『I will have a good time』; ② Verb Tense Error: According to English grammar rules, expressing future plans or intentions requires the future tense. Considering the context, this describes having fun during the weekend (future time). Therefore, the future tense 『will have』 should be used, changing the sentence to 『I will have a good time』.

Error analysis:
error_sentence: My father is going to visit my grandparent's.
correct_sentence: My father is going to visit my grandparents.
error: grandparent's
correction: grandparents
error_type: Noun Possessive Error
error_severity: 3
error_description: ① Noun Possessive Error: According to English grammar rules, the noun possessive “'s” is used to indicate possession. In this sentence, the context expresses visiting grandparents, not emphasizing possession, so 〈grandparent's〉 should be changed to 『grandparents』 as the object; ② Noun Number Error: According to English grammar rules, “grandparent” refers to a single grandparent, while “grandparents” refers to both grandparents. Based on the prompt, this sentence expresses the father visiting both grandparents, therefore 〈grandparent's〉 should be changed to the plural form 『grandparents』.
error_sentence: I have a great day
correct_sentence: I will have a great day.
correction: will
error_type: Verb Tense Error
error_severity: 3
error_description: ① Verb Tense Error: According to English grammar rules, future plans or intentions should be expressed using the simple future tense. Based on the prompt requirements and context, this passage should use the future tense, whereas the original sentence 〈I have a great day〉 uses the simple present tense, failing to convey the meaning of “will have a great day in the future”. Therefore, the sentence should be changed to 『I will have a great day』, using the future tense for accurate expression.
error_sentence: I have a great day
correct_sentence: I will have a great day.
correction: .
error_type: Punctuation Error
error_severity: 2
error_description: ① Punctuation Error: According to English writing conventions, a declarative sentence needs a period at the end to clearly indicate its conclusion. The original sentence 〈I have a great day〉, being a declarative sentence, lacks a period at the end, so a 『.』 should be added after 〈day〉 to comply with the punctuation rules for English declarative sentences.

correct_sentence: My grandparents are watching TV, and my brother is playing computer games.
error: grandparent is
correction: grandparents are
error_type: Subject-Verb Agreement Error
error_severity: 3
error_description: ① Noun Number Error: According to the prompt requirements, the singular noun 〈grandparent〉 should be changed to the plural noun 『grandparents』 following English plural rules for semantic accuracy; ② Subject-Verb Agreement Error: According to the English subject-verb agreement principle, the plural subject 〈grandparents〉 requires the verb to be in the plural form. The original sentence incorrectly uses the singular verb 〈is〉, so it is corrected to the plural verb 『are』 according to grammatical rules to maintain subject-verb agreement in number.
error_sentence: Where is my mother doing?
correct_sentence: What is my mother doing?
error: Where
correction: What
error_type: Pronoun Error
error_severity: 3
error_description: Pronoun Error: According to English interrogative word usage norms, 〈Where〉, as an interrogative pronoun for place, is only applicable for inquiring about spatial location. The current sentence meaning is clearly inquiring about a specific action, therefore the misused place interrogative word 〈Where〉 is corrected to the action interrogative word 『What』.
error_sentence: Oh, she cooking and my sister is listening to the radio.
correct_sentence: Oh, she is cooking, and my sister is listening to the radio.
error: cooking
correction: is cooking,
error_type: Auxiliary Error
error_severity: 4
error_description: ① Auxiliary Error: According to the formation rules of the English present continuous tense, the predicate part must include the be verb + present participle, therefore the auxiliary verb 『is』 needs to be added to 〈she cooking〉 to form a complete tense structure; ② Punctuation Error: According to English compound sentence writing norms, a comma plus a conjunction 『, and』 should be used to connect the two independent clauses 〈she is cooking〉 and 〈my sister is listening to the radio〉 to comply with standard written language requirements. Added a comma.

error_severity: 4
error_description: ① Space Error: Based on English writing conventions, a space is needed before 〈p.m.〉 in the time expression 〈3:00p.m.〉, changed to 『3:00 p.m.』; ② Punctuation Error: According to the sentence meaning, a comma is needed after the introductory time phrase 〈At 3:00p.m.〉, so 『,』 is added after 〈p.m.〉 to separate the time phrase from the main clause; ③ Case Error: The name 〈linda〉 is a proper noun; according to English writing conventions, the first letter should be capitalized, corrected to 『Linda』.
error_sentence: A young lady is looking at the shoe store!
correct_sentence: A young lady is looking at a shoe store.
error: the
correction: a
error_type: Determiner Error
error_severity: 2
error_description: Determiner Error: The determiner 〈the〉 indicates specificity, but according to the sentence meaning, this is the first mention of 〈shoe store〉 without specifying a particular one, so it needs to be changed to 『a』 to indicate a general shoe store, fitting the context.

error: ba
correction: on a
error_type: Spelling Error
error_severity: 2
error_description: ① Spelling Error: According to the sentence meaning, the intention is to express the action of "trying on shoes"; the original 〈ba〉 is unclear and should be changed to 『on』 to fit the sentence semantics and correctly express the mother's action of trying on shoes; ② Determiner Error: According to the fixed English expression, the correct phrase for "一双，一对" is "a pair of"; it is evident that the indefinite article "a" is missing before 〈pair〉 in the original sentence, so 『a』 needs to be added before 〈pair〉.

correction: Saturday
error_type: Spelling Error

error_type: Preposition Error
error_severity: 5
error_description: ① Preposition Error: In English, expressing "on a specific day of the week" requires the preposition “on” before the day; therefore, the sentence 〈Sunday, I did my homework〉 is missing the preposition 〈On〉 to modify 〈Sunday〉 at the beginning, so 『On』 needs to be added at the start of the sentence.
error_sentence: Sunday, I did my homework and cleaned the hose with my family members.
correct_sentence: On Sunday, I did my homework and cleaned the house with my family members.
error: hose
correction: house

error_type: Subject-Verb Agreement Error
error_severity: 4
error_description: ① Spelling Error: According to the original sentence, the noun 〈classcase〉 does not fit the meaning; the sentence intends to express “classmate”, so the correct spelling should be 『classmate』; ② Subject-Verb Agreement Error: Since the subject 〈My classmate〉 is third-person singular, and 〈wear〉 is the third-person plural form, the verb 〈wear〉 needs to be changed to 『wears』 to follow the subject-verb agreement principle.

error: looks
correction: look
error_type: Subject-Verb Agreement Error
error_severity: 3
error_description: Subject-Verb Agreement Error: According to English grammar rules, the subject 〈They〉 is plural, while the original 〈looks〉 is the third-person singular form; therefore, the verb 『look』 should be used instead of 〈looks〉 to maintain subject-verb agreement in number.

error_type: Sentence Structure Error
error_severity: 4
