Error analysis:
error_sentence: She is seeing many people do some things.
correct_sentence: She is watching many people do some things.
error: seeing
correction: watching
error_type: Verb Choice Error
error_severity: 3
error_description: Verb Choice Error: According to English expression habits and context, the verb 〈seeing〉 usually means 'to see' in a sensory way, while 『watching』 means to consciously observe a continuous action; the original sentence describes the action of observing others' behavior, so 〈seeing〉 needs to be changed to 『watching』 to fit the context.
error_sentence: A little gril is buying some food.
correct_sentence: A little girl is buying some food.
error: gril
correction: girl
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: According to the meaning of the sentence, it is clear that the intention here is to express 'girl', therefore 〈gril〉 is a misspelling of 『girl』; it needs to be changed to 『girl』 to make the sentence coherent.
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 English expression habits, the verb 〈trying〉 in the original sentence would be misunderstood as 'attempting', which does not fit the sentence's meaning, while the phrasal verb “try on” means “to test clothing by putting it on”, and is a fixed phrase; lacking the preposition 『on』 leads to incomplete semantics, therefore 『on』 needs to be added after 〈trying the shoes〉 to conform to English expression habits and the prompt's requirements.
error_sentence: And Linda's father is staying on the sofa to wait for Linda's mothe
correct_sentence: And Linda's father is staying on the sofa, waiting for Linda's mother.
error: to wait
correction: , waiting
error_type: Nonfinite Verb Form Error
error_severity: 3
error_description: ① Nonfinite Verb Form Error: According to the context, a present participle form expressing a concomitant state is required here; in the original sentence, 〈to wait〉 as an adverbial of purpose does not fit the semantic logic of a concomitant action, so it is changed to the present participle 『waiting』 as a concomitant adverbial to fit the context; ② Punctuation Error: According to English grammar rules, a comma is needed to separate the main clause and the concomitant adverbial, therefore the original 〈to wait〉 needs to be changed to 『, waiting』 to conform to grammatical rules.
error_sentence: And Linda's father is staying on the sofa to wait for Linda's mothe
correct_sentence: And Linda's father is staying on the sofa, waiting for Linda's mother.
error: mothe
correction: mother.
error_type: Punctuation Error
error_severity: 3
error_description: ① Spelling Error: According to the meaning of the sentence, it is clear that the intention here is to express 'mother', therefore 〈mothe〉 is a misspelling of 『mother』; 〈mothe〉 needs to be changed to 『mother』 to make the sentence coherent; ② Punctuation Error: According to writing conventions, a complete sentence requires a period; the original sentence 〈And Linda's father...〉 is structurally complete but lacks a period at the end, therefore a 『.』 is added at the end of the sentence to conform to English punctuation usage rules.
