error_type: Preposition Error
error_severity: 3
error_description: Preposition Error: According to the prompt, the present continuous tense should be used to describe what is seen and heard. 〈going to a shopping center〉 means 'planning to go to the store', not yet arrived, while 『at a shopping center』 means 'already inside the store', which better fits the context of observing 『at the mall』. Therefore, 〈going to〉 should be changed to the preposition 『at』.
error_sentence: I see a little gril is buying some food on supermaket.
correct_sentence: I see a little girl buying some food at the supermarket.
error: gril is
correction: girl
error_type: Nonfinite Verb Form Error
error_severity: 4
error_description: ① Spelling Error: According to English spelling conventions, 'girl' 〈gril〉 is misspelled; the correct spelling is 『girl』; ② Nonfinite Verb Form Error: According to English usage, 'see sb. doing sth.' is the expression for 'seeing someone doing something'. Therefore, the main verb 〈see〉 should be followed by the present participle 『buying』, requiring the removal of 〈is〉 from 〈is buying〉 to mean 'seeing someone buying something'.
error_sentence: I see a little gril is buying some food on supermaket.
correct_sentence: I see a little girl buying some food at the supermarket.
error: on supermaket
correction: at the supermarket
error_type: Preposition Error
error_severity: 4
error_description: ① Preposition Error: In English, the preposition 『at』 should be used for specific locations, not 〈on〉; here, the meaning is 'in the supermarket', so 〈on〉 should be changed to 『at』; ② Determiner Error: According to English grammar rules, singular countable nouns usually require a determiner; here, 〈supermaket〉 lacks a determiner and should have 『the』 added for specific reference; ③ Spelling Error: According to English spelling conventions, 〈supermaket〉 is misspelled; the correct spelling is 『supermarket』, meaning 'supermarket'.
error_sentence: I see a young lidy is looking the nice dress on the clothes shop.
correct_sentence: I see a young lady looking at a nice dress in the clothes shop.
error: lidy is looking the
correction: lady looking at a
error_type: Nonfinite Verb Form Error
error_severity: 5
error_description: ① Spelling Error: According to English spelling conventions, 〈lidy〉 is misspelled; the correct spelling is 『lady』, meaning 'lady'; ② Nonfinite Verb Form Error: According to English usage, 'see sb. doing sth.' is the expression for 'seeing someone doing something'. Therefore, the main verb 〈see〉 should be followed by the present participle 『looking』, requiring the removal of 〈is〉 from 〈is looking〉; ③ Preposition Error: According to the English fixed phrase, 'look at' means 'to look at something', so 『at』 needs to be added between 'look' and 〈dress〉 to form the fixed phrase; ④ Determiner Error: According to the sentence meaning, the intention is 'I see a young lady looking at a dress', not specifying which dress, and the dress has not been mentioned before, so 〈the〉 should be replaced with 『a』 to simply express 'a dress'.
error_sentence: I see a young lidy is looking the nice dress on the clothes shop.
correct_sentence: I see a young lady looking at a nice dress in the clothes shop.
error: on
correction: in
error_type: Preposition Error
error_severity: 3
error_description: Preposition Error: According to English usage, the preposition 'in' emphasizes being inside or within a range, while 'on' emphasizes surface contact. Here, 'in the clothes shop' refers to an indoor location, so the preposition 『in』 should be used before 〈clothes shop〉 instead of 〈on〉, conforming to English preposition rules.
error_sentence: My mother is trying the shoes on the shoes shop.
correct_sentence: My mother is trying on shoes in the shoe shop.
error: the shoes on the shoes
correction: on shoes in the shoe
error_type: Noun Number Error
error_severity: 4
error_description: ① Noun Error: According to English rules, when a noun functions as an attributive, it is usually in singular form, thus 〈shoes shop〉 should be the compound noun 『shoe shop』; ② Preposition Error: 'Inside the shop' in English should use the preposition 『in』, not 〈on〉; ③ Determiner Error: 『try on shoes』 here means 'to try on shoes' in general, without specifying particular shoes. Therefore, 〈the〉 should be removed.
error_sentence: And my father is waiting my mother on the sofa.
correct_sentence: And my father is waiting for my mother on the sofa.
correction: for
error_type: Preposition Error
error_severity: 3
error_description: Preposition Error: Missing preposition: According to the English fixed phrase, the expression for 'waiting for someone' is 'wait for sb.'. Here, the meaning is 'waiting for mother', so the fixed preposition 『for』 needs to be added between 〈wait〉 and the object.
