error_type: Word Redundancy Error
error_severity: 5
error_description: ① Space Error: According to English writing conventions, spaces are needed between words. The original phrase 〈At3:00p.m.〉 lacks necessary spaces, so it is corrected to 『At 3:00 p.m.』 to comply with English writing norms.; ② Punctuation Error: According to English expression conventions, the time adverbial 〈At3:00p.m.〉 at the beginning of the sentence, being an independent element, needs to be separated from the main clause by a comma. Therefore, a 『,』 is added after 『At 3:00 p.m.』 to comply with English punctuation usage rules.; ③ Verb Choice Error: According to English expression conventions and context, the verb 『see』 typically denotes sensory perception ("seeing"). The context of the original sentence describes a sensory action, so 〈am looking〉 should be changed to 『see』 to fit the context.; ④ Space Error: According to English writing conventions, spaces are needed between words. The original word 〈alittle〉 lacks a necessary space, so it is corrected to 『a little』 to comply with English writing norms.; ⑤ Word Redundancy Error: According to English grammar rules, when the verb 『see』 is followed by an object complement, the complement usually takes the present participle form to describe an ongoing action. Therefore, 〈is〉 should be deleted from 〈isbuying〉, retaining 『buying』 to comply with grammatical rules.

error_sentence: My mother is trying shoes now.
correct_sentence: My mother is trying on shoes now.
correction: on
error_type: Preposition Error
error_severity: 2
error_description: Preposition Error: According to English expression conventions, the verb 〈trying〉 in the original sentence could be misunderstood as "attempting," which does not fit the meaning. The phrasal verb “try on” means “to put on clothing to see if it fits,” which is a fixed phrase. Missing the preposition 『on』 makes the meaning incomplete. Therefore, 『on』 needs to be added after 〈trying〉 to conform to English expression conventions and the prompt requirements.

correct_sentence: My father is staying on the sofa and waiting for us.
error: Myfather
correction: My father
error_type: Space Error
error_severity: 1
error_description: Space Error: According to English writing conventions, spaces are needed between words. The original word 〈Myfather〉 lacks a necessary space, so it is corrected to 『My father』 to comply with English writing norms.

error_sentence: Myfather is staying at sofe wait foy us
correct_sentence: My father is staying on the sofa and waiting for us.
error: at sofe wait foy us
correction: on the sofa and waiting for us.
error_type: Conjunction Error
error_severity: 5
error_description: ① Preposition Error: According to English expression conventions, the preposition 『on』 is used to indicate "on the surface of...". Therefore, 〈at〉 in the original sentence should be changed to 『on』 to correctly express the position of the action "father sitting on the sofa".; ② Determiner Error: According to English grammar rules, the definite article 『the』 indicates specificity. The original word 〈sofe〉 lacks the necessary determiner 『the』 to specify the object, so 『the』 needs to be added before 〈sofe〉 to clarify the meaning.; ③ Spelling Error: Based on the sentence meaning, the intended word is "sofa". Therefore, 〈sofe〉 is a misspelling of 『sofa』 and needs to be corrected to 『sofa』 for the sentence to make sense.; ④ Conjunction Error: According to English grammar rules, 〈staying〉 and “waiting” are parallel verbs in the original sentence and require the conjunction 『and』 to connect them, conforming to English grammar rules.; ⑤ Verb Tense Error: According to English grammar rules and the prompt requirements, the present continuous tense is required, typically structured as "be doing". However, 〈wait〉 in the original sentence is in the simple present tense. Therefore, 〈wait〉 needs to be changed to the present participle 『waiting』 to comply with grammatical rules.; ⑥ Spelling Error: Based on the sentence meaning, this word forms a phrase with 〈wait〉. Therefore, 〈foy〉 is a misspelling of 『for』 and needs to be corrected to 『for』 for the sentence to make sense.; ⑦ Punctuation Error: According to writing conventions, a complete sentence requires a period. The structure 〈wait foy us〉 is complete, but it lacks a period at the end. Therefore, it is corrected to 『waiting for us.』 to comply with English punctuation usage rules.
