error_type: Subject-Verb Agreement Error
error_severity: 3
error_description: ① Noun Number Error: 〈families〉 indicates multiple families or family members, but here it refers to Linda's family as a single unit, requiring the singular form. Therefore, 〈families〉 should be changed to the singular form 『family』 to match the original meaning and grammatical rules; ② Subject-Verb Agreement Error: The third-person singular subject 〈family〉 requires the third-person singular form of the verb. There is a subject-verb agreement error here. The plural 〈are〉 needs to be changed to the third-person singular present tense form 『is』 to align with the context's tense and the principle of subject-verb agreement.

error_sentence: Linda is helping her mofher do housework.
correct_sentence: Linda is helping her mother do housework.

error_severity: 2

error_sentence: The dinner that her mother is cooking.
correct_sentence: Her mother is cooking dinner.
error: The dinner that her
correction: Her
error_type: Sentence Structure Error
error_severity: 4
error_description: Sentence Structure Error: According to the original meaning, the intention is to express 'Her mother is cooking dinner'. This requires a subject-verb-object sentence structure. However, the original sentence uses the structure of subject 〈The dinner〉 plus a relative clause 〈that her mother is cooking〉, meaning 'The dinner that her mother is cooking'. The original sentence structure is confusing and the meaning does not fit the context. 〈The dinner that〉 should be deleted to adjust the sentence structure. According to English writing conventions, the first letter of a sentence should be capitalized. Therefore, after adjusting the structure, the subject 'her mother' is at the beginning of the sentence, and 〈her〉 should be changed to 『Her』 to start an independent sentence.

error_sentence: The dinner that her mother is cooking.
correct_sentence: Her mother is cooking dinner.
correction: dinner
error_type: Noun Error
error_severity: 3
error_description: Noun Error: According to the original meaning, the intention is to express 'Her mother is cooking dinner'. The verb 〈cooking〉 needs an object to specify the action's target. Therefore, there is a missing noun error here. The noun 『dinner』 needs to be added after 〈cooking〉 to make the sentence semantically complete.

error_sentence: The games that her brother is playing.
correct_sentence: Her brother is playing computer games.
error: The games that her
correction: Her
error_type: Sentence Structure Error
error_severity: 4
error_description: Sentence Structure Error: According to the original meaning, the intention is to express 'Her brother is playing computer games'. This requires a subject-verb-object sentence structure. However, the original sentence uses the structure of subject 〈The games〉 plus a relative clause 〈that her brother is playing〉, meaning 'The computer games that her brother is playing'. The original sentence structure is confusing and the meaning does not fit the context. 〈The games that〉 should be deleted to adjust the sentence structure. According to English writing conventions, the first letter of a sentence should be capitalized. Therefore, after adjusting the structure, the subject 'her brother' is at the beginning of the sentence, and 〈her〉 should be changed to 『Her』 to start an independent sentence.

error_sentence: The games that her brother is playing. The radio who Linda's sister is listening.
correct_sentence: Her brother is playing computer games.
error: . The radio who
correction: computer games.
error_type: Sentence Structure Error
error_severity: 4
error_description: ① Sentence Structure Error: According to the original meaning, the intention is to express 'Her brother is playing computer games'. Based on the previous correction, the verb 〈playing〉 needs an object to specify the action's target. The original text has redundant components across two sentences. The beginning of the next sentence 〈. The radio who〉 can be replaced with 『computer games』 to serve as the object of the verb 〈playing〉, making the previous sentence semantically complete; ② Punctuation Error: According to English syntax rules, an independent sentence needs an appropriate punctuation mark at the end to indicate its conclusion. Therefore, the revised sentence lacks a period at the end. A 『.』 needs to be added after 〈games〉 to mark the end of the sentence in accordance with English syntax rules.

error_sentence: The radio who Linda's sister is listening.
correct_sentence: Linda's sister is listening to the radio.
correction: to the radio
error_type: Sentence Structure Error
error_severity: 4
error_description: Sentence Structure Error: According to the original meaning, the intention is to express 'Linda's sister is listening to the radio', which requires a subject-verb-object structure. Based on the previous corrections, the verb 〈listening〉 needs an object to specify the action's target. Furthermore, according to English grammar rules, the intransitive verb 'listen' requires the preposition 'to' to form a transitive verb phrase. Therefore, the sentence components are incomplete, resulting in a sentence structure error. 『to the radio』 needs to be added after 〈listening〉 to match the original meaning and syntactic rules.
