error_type: Subject-Verb Agreement Error
error_severity: 2
error_description: Subject-Verb Agreement Error: According to English grammar rules for verb conjugation in the third-person singular present tense, the subject 〈Linda〉, being a singular third-person subject, requires its predicate verb to take the corresponding singular form. The original sentence uses the base form 〈see〉, violating the subject-verb agreement principle; therefore, the base form 〈see〉 is changed to the third-person singular form 『sees』, forming the correct subject-verb structure 『Linda sees』 to ensure agreement in number between the subject and the predicate.

error_sentence: Now is 3 p.m.Linda see a little girl is buying some food.
correct_sentence: Now is 3 p.m. Linda sees a little girl buying some food.
error: is
error_type: Word Redundancy Error
error_severity: 2
error_description: Word Redundancy Error: According to the usage rules for English sensory verbs, when the sensory verb 〈sees〉 is followed by an object complement and indicates an ongoing action, the present participle should be used directly to form a complex object structure (i.e., the 'see sb. doing' structure). The original sentence incorrectly adds the linking verb 〈is〉, creating a redundant progressive tense structure and violating the grammatical rule for sensory verbs with object complements. Therefore, the superfluous linking verb 〈is〉 is deleted, and 〈is buying〉 is changed to the present participle form 『buying』, forming the correct sensory verb with object complement structure 'sees sb. buying' to accurately express the meaning 'see someone doing something'.

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 fixed collocation rules for English phrasal verbs, 'try on', as a transitive phrasal verb meaning 'to put on clothing to see if it fits', must maintain its complete structure. The original sentence omits the necessary preposition 〈on〉, resulting in an incomplete phrasal verb. Therefore, the missing preposition 『on』 is added after the verb 〈trying〉 to form the complete phrasal verb structure 『trying on』, in order to accurately express the meaning of the action 'trying on clothes'.

error_sentence: Her father is staying on the sofa and wait of her mother.
correct_sentence: Linda's father is staying on the sofa and waiting for her mother.
error: Her
correction: Linda's
error_type: Pronoun Error
error_severity: 3
error_description: Pronoun Error: According to the principle of clear reference in English, when using the possessive pronoun 〈Her〉, there must be a clear corresponding female singular antecedent in the preceding text. Due to the lack of a clear female referent earlier, this possessive pronoun causes ambiguity. Therefore, the ambiguous possessive pronoun 〈Her〉 is changed to the possessive noun form 『Linda's』, directly linking to the previously mentioned subject 〈Linda〉, establishing a clear possessive relationship and ensuring referential accuracy and sentence coherence. This modification also aligns with the basic requirement in English writing to avoid ambiguous references.

error_sentence: Her father is staying on the sofa and wait of her mother.
correct_sentence: Linda's father is staying on the sofa and waiting for her mother.
error: wait of
correction: waiting for
error_type: Nonfinite Verb Form Error
error_severity: 3
error_description: ① Nonfinite Verb Form Error: According to the principle of parallel structure in English, coordinate elements should maintain grammatical consistency. In the original sentence, 〈staying〉 is a present participle, while 〈wait〉 is a base form verb, disrupting the balance of the parallel structure. Therefore, the base form verb 〈wait〉 is changed to the present participle form 『waiting』, forming the parallel structure 'staying and waiting' to ensure the two coordinate actions are grammatically identical; ② Preposition Error: The phrasal verb 'wait for' is a fixed collocation meaning 'to await someone/something'. The original sentence incorrectly uses 〈of〉, resulting in an incorrect collocation. Therefore, the incorrect preposition 〈of〉 is changed to the correct preposition 『for』, forming the idiomatic structure 『waiting for』 to accurately express the meaning of 'waiting'.
