error_type: Punctuation Error
error_severity: 2
error_description: ① Contraction Error: According to English writing conventions, the time expression 〈Its〉 should use the complete contraction form 『It's』 to mean 'it is'; the original sentence's 〈Its〉 lacks the necessary apostrophe, so 〈Its〉 needs to be changed to 『It's』; ② Punctuation Error: According to English punctuation rules, the complete time expression requires adding 『pm』, and the time adverbial should be separated from the main clause by a period. The original sentence 〈Its 3:00,〉 did not add 『pm』 and used a comma, so 〈Its 3:00,〉 is changed to 『It's 3:00 pm.』 to comply with punctuation standards.

error_sentence: Its 3:00, Linda is at the shop hall, She sees a little gril is buying some food, she sees a young lady is looking at a pretty dress.
correct_sentence: Linda is at the shopping mall.
error: shop hall,
correction: shopping mall.
error_type: Noun Error
error_severity: 4
error_description: ① Noun Error: According to English fixed expressions, 『shopping mall』 should be used to express 'mall'; 〈shop hall〉 does not fit the meaning, so 〈shop hall〉 is changed to 『shopping mall』 to accurately convey the meaning of a mall; ② Punctuation Error: Since 〈Linda is at the shop hall〉 and the following clause are two independent sentences with complete subject-verb structures and no conjunction connecting them, the comma 〈,〉 is changed to a period 『.』 to comply with standards.

error_sentence: Its 3:00, Linda is at the shop hall, She sees a little gril is buying some food, she sees a young lady is looking at a pretty dress.
correct_sentence: She sees a little girl buying some food, and she sees a young lady looking at a pretty dress.
error: gril is
correction: girl
error_type: Word Redundancy Error
error_severity: 4
error_description: ① Spelling Error: According to the sentence meaning, the intention here is to express 'girl'; 〈gril〉 is a misspelling of 『girl』, so 〈gril〉 is changed to 『girl』 to follow correct spelling rules; ② Word Redundancy Error: According to the original sentence structure, this is a 'see sb. doing sth' construction meaning 'see someone doing something', therefore the redundant auxiliary verb 〈is〉 needs to be deleted.

error_sentence: Its 3:00, Linda is at the shop hall, She sees a little gril is buying some food, she sees a young lady is looking at a pretty dress.
correct_sentence: She sees a little girl buying some food, and she sees a young lady looking at a pretty dress.
correction: and
error_type: Conjunction Error
error_severity: 3
error_description: ① Conjunction Error: According to English grammar rules, parallel clauses need to be connected by the conjunction 〈and〉; the original sentence lacks a conjunction, so 『and』 is added to maintain coherence.

error_type: Word Redundancy Error
error_severity: 4
error_description: ① Word Redundancy Error: According to English grammar rules, when the sensory verb 〈sees〉 is followed by an object complement indicating an ongoing action, the present participle form is sufficient, and no extra verb is needed. The 〈is〉 in the original sentence is redundant; therefore, 〈is〉 should be deleted to make the sentence more concise and conform to standard expression.

error_sentence: Linda sees her mother is try the shoes, she sees her father is staying on the sofa, he's waiting for Linda's mother.
correct_sentence: Linda sees her mother trying on the shoes.
error: is try
correction: trying on
error_type: Nonfinite Verb Form Error
error_severity: 3
error_description: ① Nonfinite Verb Form Error: According to English grammar rules, when the sensory verb 〈sees〉 is followed by an object complement indicating an ongoing action, the present participle form is required. The original phrase 〈is try〉 does not follow this rule and is a nonfinite verb form error; it should be changed to 『trying on』; ② Preposition Error: When the verb 〈try〉 means 'to try on', it is an intransitive verb and needs to be paired with the preposition 〈on〉 to form the phrasal verb 『try on』. The original sentence lacks the preposition 〈on〉, which is a preposition error, so 〈on〉 needs to be added.

error_sentence: Linda sees her mother is try the shoes, she sees her father is staying on the sofa, he's waiting for Linda's mother.
correct_sentence: Linda sees her mother trying on the shoes. She sees her father staying on the sofa.
error: , she
correction: . She
error_type: Punctuation Error
error_severity: 2
error_description: ① Punctuation Error: According to English grammar rules, two independent clauses need to be separated by a period; in the original sentence, 〈, she〉 uses a comma to connect two independent clauses, which does not conform to standards, so the comma 〈,〉 should be changed to a period 『.』; ② Case Error: According to English writing conventions, the first letter of a word at the beginning of a sentence needs to be capitalized; in the original sentence, 〈she〉 is at the beginning of the sentence, but its first letter is not capitalized, so 〈she〉 should be changed to 『She』.

error_sentence: Linda sees her mother is try the shoes, she sees her father is staying on the sofa, he's waiting for Linda's mother.
correct_sentence: She sees her father staying on the sofa.
error: is
error_type: Word Redundancy Error
error_severity: 4
error_description: ① Word Redundancy Error: According to English grammar rules, in the 'sees sb. doing sth.' structure, the sensory verb 〈sees〉 is followed by the present participle form as an object complement, requiring no extra verb. Therefore, 〈is〉 should be deleted to make the sentence conform to standard expression.

error_sentence: Linda sees her mother is try the shoes, she sees her father is staying on the sofa, he's waiting for Linda's mother.
correct_sentence: She sees her father staying on the sofa. He's waiting for Linda's mother.

error_type: Punctuation Error
error_severity: 2
