error_type: Word Order Error
error_severity: 5
error_description: ① Spelling Error: According to the sentence meaning, it intends to express "we", so 〈W〉 is a misspelling of 『We』; it needs to be changed to 『We』 to make the sentence coherent; ② Word Order Error: According to English word order rules, the adverb 〈also〉 should be placed after the auxiliary verb 〈will〉, so 〈also will〉 is adjusted to 『will also』 to conform to English word order rules.
error_sentence: Welcome to china.
correct_sentence: Welcome to China.
error: china
correction: China
error_type: Case Error
error_severity: 1
error_description: Case Error: According to English writing conventions, proper nouns require capitalization of the first letter; 〈china〉 as a country name needs its first letter capitalized, therefore it needs to be changed to 『China』 to comply with the convention.
error_sentence: Come and join to us.
correct_sentence: Come and join us.
error: to
error_type: Preposition Error
error_severity: 2
error_description: Preposition Error: According to English grammar rules, transitive verbs can be directly followed by an object; in the original sentence, 〈join〉 is a transitive verb and can directly take the object 〈us〉 without needing the preposition 〈to〉, therefore the redundant 〈to〉 is deleted to conform to grammar rules.

Error analysis:
error_sentence: We have a great time.
correct_sentence: We are going to have a good time.
correction: are going to
error_type: Verb Tense Error
error_severity: 3
error_description: Verb Tense Error: According to the context and prompts, the sentence describes a planned future activity and should use the future tense; the original sentence 〈We have〉 uses the simple present tense, which is a tense error, so 〈We have〉 needs to be changed to 『are going to have』 to express a planned future action, fitting the context.
error_sentence: We have a great time.
correct_sentence: We are going to have a good time.
error: great
correction: good
error_type: Adjective Error
error_severity: 2
error_description: Adjective Error: According to the task requirements and given prompts, the fixed phrase 『have a good time』 should be used; 〈great〉 in the original sentence, although similar in meaning, is a word choice error, therefore 〈great〉 needs to be replaced with 『good』 to comply with the task prompt requirements.
error_sentence: We are going to flying a kite.
correct_sentence: We are going to fly a kite.
error: flying
correction: fly
error_type: Nonfinite Verb Form Error
error_severity: 3
error_description: Nonfinite Verb Form Error: According to English grammar rules, the 'be going to' structure must be followed by the base form of the verb; the original sentence uses 〈flying〉, which is the present participle form, therefore 〈flying〉 needs to be changed to 『fly』 to comply with grammatical rules.

Error analysis:
error_sentence: His name is steve.
correct_sentence: His name is Steve.
error: steve
correction: Steve
error_type: Case Error
error_severity: 1
error_description: Case Error: According to English writing conventions, the first letter of a person's name must be capitalized; as a person's name, the first letter of 〈steve〉 needs to be capitalized, so it needs to be modified to 『Steve』 to conform to the convention.
error_sentence: He is a teacher man of 42 years old.
correct_sentence: He is a teacher of 42 years old.
error: man
error_type: Word Redundancy Error
error_severity: 4
error_description: Word Redundancy Error: According to English expression habits, 〈teacher〉 in the original sentence already clearly indicates the professional identity; 〈man〉 is a redundant component whose deletion does not affect the completeness or meaning of the sentence, therefore 〈teacher man〉 is modified to 『teacher』 to make the sentence more concise, fluent, and conform to English expression habits.
error_sentence: This is my moher Mayra.
correct_sentence: This is my mother Mayra.
error: moher
correction: mother
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: According to the meaning of the sentence, it is clear that the intended meaning here is 'mother'; 〈moher〉 is a misspelling of 『mother』, so 〈moher〉 needs to be modified to 『mother』 to make the sentence meaning clear.

correct_sentence: I am Tommy, I had a good time last weekend.
error: have
correction: had
error_type: Verb Tense Error
error_severity: 3
error_description: Verb Tense Error: The time adverbial 〈last weekend〉 indicates past time, so the predicate verb should be in the past tense; therefore, 〈have〉 is changed to 『had』 to maintain tense consistency.
error_sentence: I am Tommy, I have a good time on my last weekend.
correct_sentence: I am Tommy, I had a good time last weekend.
error: on my
error_type: Word Redundancy Error
error_severity: 4
error_description: Word Redundancy Error: According to the prompt asking to describe life last weekend, the English expression for last weekend is “last weekend”, which does not require a preceding preposition; the words 〈on〉 and 〈my〉 in 〈on my last weekend〉 are redundant, thus 〈on my〉 is deleted to ensure semantic completeness.
error_sentence: On Sunday, I did my homework at 9:00.
correct_sentence: On Sunday, I did my homework at 9:00 a.m.
error: .
correction: a.m.
error_type: Determiner Error
error_severity: 3
error_description: Determiner Error: According to English writing conventions, in daily writing, to specify the exact time, a.m. (morning) or p.m. (afternoon) is usually indicated; therefore, 『a.m.』 is added after 〈9:00〉 to clarify the time is 9 o'clock in the morning.
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

Student essay:

Corrected essay:
She is my best friend. Today, she wears a pink shirt and pure white shoes. They look very beautiful. I like what she wears.

Error analysis:
error_sentence: She is my the best friend.
correct_sentence: She is my best friend.
error: the
error_type: Word Redundancy Error
error_severity: 4
error_description: Word Redundancy Error: 〈my〉 already serves as a possessive determiner modifying 〈best friend〉; there is no need to add the definite article 〈the〉 as their functions are redundant, so the superfluous 『the』 is deleted to comply with English determiner usage rules.
error_sentence: Today, she wears a pink shirt and the pure white shoes.
correct_sentence: Today, she wears a pink shirt and pure white shoes.
error: the
error_type: Word Redundancy Error
error_severity: 4
error_description: Word Redundancy Error: When using 〈pure white〉 as an adjective before the plural noun 〈shoes〉, the definite article 〈the〉 is unnecessary because it does not refer to a specific pair of shoes but rather generally to “pure white shoes”; therefore, 『the』 is deleted to conform to article usage norms.
error_sentence: Look very beautiful.
correct_sentence: They look very beautiful.
error: Look
correction: They look
error_type: Sentence Structure Error
error_severity: 4
error_description: Sentence Structure Error: The sentence lacks a clear subject, making it incomplete. According to the context, the subject 『They』 needs to be added to refer to the previously mentioned “a pink shirt and the pure white shoes,” and the linking verb 〈look〉 should be retained to form a complete subject-verb-complement structure; therefore, 〈Look〉 is changed to 『They look』 to make the sentence structure complete.
error_sentence: l like she wear.
correct_sentence: I like what she wears.
error: l like she wear
correction: I like what she wears
error_type: Conjunction Error
error_severity: 5
error_description: ① Spelling Error: According to the sentence meaning, the subject here is intended to be “I”, so 〈l〉 is changed to 『I』 to conform to English spelling norms. ② Sentence Structure Error: According to English grammar rules, 〈I like she wear〉 lacks the necessary connective word “what” to link the main clause with the object clause; therefore, 『what』 should be added before 〈she〉 to complete the object clause structure; ③ Subject-Verb Agreement Error: According to English grammar rules, the tense of the object clause should be consistent with the tense of the main clause. The main clause 〈like〉 is in the simple present tense, so the verb 〈wear〉 in the object clause should also be in the simple present tense, and according to the principle of subject-verb agreement, 〈wear〉 in the clause should be changed to the third-person singular form 『wears』.

correction: Saturday
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English syntax rules, multiple parallel items in an English sentence should be separated by commas, with 『and』 connecting the last two items. Therefore, there is a punctuation error here. The 〈and〉 in the original phrase 〈clean my room and play computer games 〉 should be changed to 『,』, forming the standard parallel structure 『visit...,,clean...,,play...,,and...』 to comply with English syntax rules.
error_sentence: Last sunday, I did my homework.
correct_sentence: Last Sunday, I did my homework.
error: sunday
correction: Sunday
error_type: Nonfinite Verb Form Error
error_severity: 4
error_description: ① Punctuation Error: According to English syntax rules, when listing multiple items, a comma 〈,〉 and the conjunction 〈and〉 are needed between the last two items. Therefore, a comma needs to be added before 〈and play〉 to separate it from the preceding item, changing it to 『, and play』 to conform to English writing conventions and syntax rules; ② Nonfinite Verb Form Error: According to English grammar rules, 〈be going to〉 should be followed by the base form of the verb, but 〈plying〉 is a misspelling of the present participle form 'playing', and should be changed to the base form 『play』 to match the original sentence meaning and grammar rules.
error_sentence: How was busy weekend!
correct_sentence: How busy my weekend was!
error: was busy weekend
correction: busy my weekend was
error_type: Word Order Error
error_severity: 4
error_description: ① Word Order Error: The structure of an exclamatory sentence should be 〈How + adjective + subject + verb〉; the original sentence places 〈was〉 before the adjective 〈busy〉, which is non-standard; ② Pronoun Error: The possessive pronoun 『my』 needs to be added before 〈weekend〉 to clarify possession. Therefore, 〈How was busy weekend〉 is corrected to 『How busy my weekend was』.

error_sentence: Besude my mother is my handsome father.
correct_sentence: Beside my mother is my handsome father.
error: Besude
correction: Beside
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: According to the sentence meaning, the intention here is to express 'next to', so 〈Besude〉 is a misspelling of 『Beside』; it needs to be changed to 『Beside』 to make the sentence coherent.
error_sentence: Theone on thefar left of the picture is my elder brother.
correct_sentence: The one on the far left of the picture is my elder brother.
error: Theone on thefar
correction: The one on the far
error_type: Space Error
error_severity: 2
error_description: Space Error: According to English writing conventions, spaces are needed between words. The original sentence lacks necessary spaces in 〈Theone〉 and 〈thefar〉, so the joined words 〈Theone〉 and 〈thefar〉 are corrected to 『The one』 and 『the far』 respectively to conform to English writing standards.
error_sentence: Hefavourite sport is skateboarding.
correct_sentence: His favourite sport is skateboarding.
error: Hefavourite
correction: His favourite
error_type: Pronoun Error
error_severity: 3
error_description: Pronoun Error: According to the sentence meaning, the intention is to express 'his'. The form 〈Hefavourite〉 in the original sentence is incorrect; the possessive 『His』 should be used. Therefore, 〈Hefavourite〉 is changed to 『His favourite』 to indicate possession and fit the context.

error_type: Format Error
error_severity: 4
error_description: ① Format Error: According to English writing conventions, essay format requires a blank line between the title and the main text, so 『\n』 needs to be added after 〈My next weekend〉 to create a line break and conform to title format standards.; ② Preposition Error: According to English grammar rules, the intended meaning here is 'on Saturday', but the original sentence 〈Saturday, 〉 omits the preposition 『On』, so 〈Saturday, 〉 is changed to 『On Saturday, 』 to comply with English grammar.
error_sentence: In the afternoon I will clean my room. Sunday morning.
correct_sentence: On Sunday morning, I am going to play computer games.
correction: On
error_type: Preposition Error
error_severity: 2
error_description: Preposition Error: According to English grammar rules, the preposition 『On』 is used for specific dates or periods of a day; the phrase 〈Sunday morning〉 in the original sentence falls into the category of a period of a day, therefore, it needs to be changed to 『On Sunday morning』 to conform to English expression conventions.
error_sentence: Sunday morning.
correct_sentence: On Sunday morning, I am going to play computer games.

In the original sentence, 〈got up early〉, 〈played with my friends〉, and 〈played basketball〉 are parallel verb phrases; using 〈and〉 consecutively is non-standard.

In the original sentence, the subject 〈It〉 refers to the preceding activities; 『exciting』 should be used to express that 'the activity was exciting', changing 〈excited〉 to 『exciting』 for accurate semantic expression; ② Punctuation Error: According to English writing conventions, a period is required at the end of a sentence to complete its structure. The original sentence lacks a period at the end; a 『.』 should be added at the end to make the writing standard.

error_type: Nonfinite Verb Form Error
error_severity: 3
error_description: ① Nonfinite Verb Form Error: According to English grammar rules, when the verb 〈like〉 is followed by a preference for an action, the structure 'to + base form of the verb' is commonly used. In the original sentence, 〈wears〉 does not conform to this structure and should be changed to 『to wear』 to make the sentence grammatically correct; ② Determiner Error: According to English grammar rules, a singular countable noun like 〈shirt〉 usually requires an article before it. In the original sentence, 〈blue shirt〉 lacks an article; 『a』 should be added to form 『a blue shirt』, making the expression conform to English grammar rules.
error_sentence: I like wears blue shirt and black shoes. Because they are beautiful
correct_sentence: I like to wear a blue shirt and black shoes because they are beautiful.
error: . Because
correction: because
error_type: Punctuation Error
error_severity: 2
error_description: ① Punctuation Error: According to English grammar rules, the adverbial clause of reason 〈because they are beautiful〉 should not be separated from the main clause 〈I like to wear a blue shirt and black shoes〉 by a period. Using a period makes the clause independent and disrupts the sentence's coherence. The period should be deleted, allowing 『because』 to directly connect to the main clause, forming a complete complex sentence with correct punctuation; ② Case Error: In English, when 『because』 introduces an adverbial clause of reason and is not the first word of the sentence, its first letter should not be capitalized. In the original sentence, the capitalization of 〈Because〉 does not conform to English writing conventions and should be changed to lowercase 『because』.
error_sentence: Because they are beautiful
correct_sentence: I like to wear a blue shirt and black shoes because they are beautiful.
correction: .
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English writing conventions, a complete English sentence requires end punctuation.

error_type: Determiner Error
error_severity: 2

error_type: Subject-Verb Agreement Error
error_severity: 5
