error_type: Sentence Structure Error
error_severity: 5
error_description: ① Pronoun Error: According to English time expression norms, the subject 〈it〉 must appear to form a fixed sentence pattern; the original sentence lacks a subject and uses the preposition incorrectly, so it is modified to 『Now it is』 to conform to the standard sentence structure “It is + time.”; ② Sentence Structure Error: According to English time expression habits, the main clause expressing “it is 7 PM” lacks a subject in the original sentence; adding 『it』 satisfies the correct expression of time; additionally, the time phrase 〈everning 7:00〉 is positioned improperly and should be adjusted to 『7:00 in the evening』 to express the meaning of “in the evening” and make the time expression more natural in word order.; ③ Spelling Error: The word 〈everning〉 is misspelled; according to English vocabulary norms, it should be corrected to the proper spelling 『evening』 to express the meaning “evening.”; ④ Preposition Error: The time point 『evening』 cannot be used alone to express a specific time period; according to English time expression rules, the prepositional structure 『in the』 needs to be added to fully specify the time range.
error_sentence: What do Linda do?
correct_sentence: What is Linda doing?
error: do Linda do
correction: is Linda doing
error_type: Nonfinite Verb Form Error
error_severity: 4
error_description: ① Auxiliary Error: According to English grammar rules, the interrogative structure of the present continuous tense should be “be verb + subject + doing,” but the original sentence 〈do Linda do〉 uses the incorrect auxiliary verb 〈do〉; since the subject 〈Linda〉 is third-person singular and expresses an ongoing action, 〈do〉 should be changed to the auxiliary verb 『is』 to form the correct present continuous interrogative sentence.; ② Nonfinite Verb Form Error: According to the meaning, the original sentence 〈do Linda do〉 attempts to express “What is Linda doing,” but the verb form is incorrect; in the present continuous tense, the verb needs to be in the present participle form (V-ing), so 〈do〉 is changed to 『doing』 to comply with the correct usage of nonfinite verbs, finally adjusting to 『What is Linda doing』.
error_sentence: Oh, she mother is cook.
correct_sentence: Oh, her mother is cooking.
error: she
correction: her
error_type: Pronoun Error
error_severity: 2
error_description: Pronoun Error: According to English grammar rules, the subjective pronoun 〈she〉 cannot directly modify a noun; here, it needs to express the possessive relationship “her mother.” Therefore, the subjective pronoun 〈she〉 should be changed to the possessive pronoun 『her』 to form the correct noun possessive structure 『her mother』, conforming to the grammatical norm of possessive adjective + noun.
error_sentence: Oh, she mother is cook.
correct_sentence: Oh, her mother is cooking.
error: cook
correction: cooking
error_type: Verb Tense Error
error_severity: 3
error_description: Verb Tense Error: According to the grammar rules of the English present continuous tense, the structure should be “be verb + present participle (V-ing)”; the original sentence uses the base form of the verb 〈cook〉, which does not meet the requirements for forming the continuous tense; therefore, it needs to be changed to the present participle form 『cooking』 to form a complete present continuous structure, thereby accurately expressing an ongoing action.
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: According to English morphological rules, the singular countable noun 〈mother〉 requires a determiner to indicate possession when specific; since the context refers to Linda's mother, the possessive adjective 『her』 should be used for specification, changing 〈mother〉 to 『her mother』 to conform to the determiner + noun grammatical structure, making the meaning complete and accurate.
error_sentence: What does she brother do?
correct_sentence: What is her brother doing?
error: does she brother do
correction: is her brother doing
error_type: Nonfinite Verb Form Error
error_severity: 5
error_description: ① Auxiliary Error: According to the interrogative structure of the English present continuous tense, the use of 〈does〉 in the original sentence does not conform to grammatical rules; present continuous interrogative sentences require a be verb, so 〈does〉 is changed to 『is』 to meet the “be verb + subject + present participle” sentence pattern requirement.; ② Pronoun Error: The subjective pronoun 〈she〉 cannot modify a noun; according to noun possessive rules, 〈she〉 should be changed to the possessive adjective 『her』 to correctly modify the noun 〈brother〉, forming the possessive expression 『her brother』.; ③ Nonfinite Verb Form Error: In the present continuous structure, the main verb must be in the present participle form; the verb 〈do〉 in the original sentence should be changed to 『doing』 to form a complete present continuous interrogative structure.
error_sentence: What does she sister do?
correct_sentence: What is her sister doing?
error: does she sister do

error_type: Nonfinite Verb Form Error
error_severity: 5
error_description: ① Auxiliary Error: According to the interrogative structure of the English present continuous tense, the use of 〈does〉 in the original sentence does not conform to grammatical rules; present continuous interrogative sentences require a be verb, so 〈does〉 is changed to 『is』 to meet the “be verb + subject + present participle” sentence pattern requirement.; ② Pronoun Error: The subjective pronoun 〈she〉 cannot modify a noun; according to noun possessive rules, 〈she〉 should be changed to the possessive adjective 『her』 to correctly modify the noun 〈sister〉, forming the possessive expression 『her sister』.; ③ Nonfinite Verb Form Error: In the present continuous structure, the main verb must be in the present participle form; the verb 〈do〉 in the original sentence should be changed to 『doing』 to form a complete present continuous interrogative structure.
error_sentence: What is a happy family!
correct_sentence: What a happy family!
error: is
error_type: Word Redundancy Error
error_severity: 3
error_description: Word Redundancy Error: According to the fixed sentence pattern norms for English exclamatory sentences, the structure for exclamations led by What should be “What + (a/an) + adjective + noun”; the linking verb 〈is〉 in the original sentence is a redundant component; therefore, 〈is〉 is deleted, and the sentence is corrected to the standard exclamatory structure 『What a happy family!』 to conform to the grammatical features and idiomatic expression habits of English exclamations.
