Error analysis:
error_sentence: At 3:00p.m.
correct_sentence: At 3:00 p.m., Linda is in the market.
error: 3:00p.m.
correction: 3:00 p.m.,
error_type: Punctuation Error
error_severity: 2
error_description: ① Space Error: The time expression 〈3:00p.m.〉 has a formatting issue; according to English writing standards, a standard space must be kept between the numerical time marker and the Latin abbreviation a.m./p.m. The original writing directly connects “3:00” and “p.m.”, causing visual adhesion and non-compliance with publication standards. The corrected 『3:00 p.m.』 inserts a space between the Arabic numerals and the abbreviation, maintaining the integrity of the time element and adhering to the international Oxford Style and APA format requirements for time symbols; the ending comma ensures a natural transition to the main clause. ② Punctuation Error: According to English writing conventions, when a time adverbial appears alone at the beginning of a sentence, it needs to be separated from the main clause by a comma; therefore, 〈3:00p.m.〉 should be changed to 『3:00 p.m.,』 to conform to standard writing format.

error_sentence: She see A little girl is buying some food, a young lady is looking at a dress, she's mother is trying the shoes.
correct_sentence: She sees a little girl buying some food, a young lady looking at a dress, and her mother trying on the shoes.
error: see A
correction: sees a
error_type: Subject-Verb Agreement Error
error_severity: 4
error_description: ① Subject-Verb Agreement Error: In English grammar, when the subject is third-person singular, the verb requires an -s or -es suffix. The original sentence's subject 〈She〉 is a singular third-person pronoun, thus the predicate verb should be 『sees』, not 〈see〉. ② Case Error: In the common noun phrase 〈a little girl〉, the article 'a' should only be capitalized at the beginning of a sentence or in a proper noun. Here, 『a』 is mid-sentence and not part of a proper noun, so it should remain lowercase, unlike the capitalized 〈A〉 in the original sentence.

error_sentence: She see A little girl is buying some food, a young lady is looking at a dress, she's mother is trying the shoes.
correct_sentence: She sees a little girl buying some food, a young lady looking at a dress, and her mother trying on the shoes.
error: is
error_type: Word Redundancy Error
error_severity: 3
error_description: Word Redundancy Error: According to English grammar rules, when sense verbs (like see, watch, hear, etc.) are followed by an object and an object complement, to emphasize the ongoing nature of the action, the present participle must be used directly as the object complement, forming the standard structure “sense verb + object + present participle” (e.g., see sb. doing sth.). The phrase 『sees a little girl buying』 already sufficiently expresses “seeing a little girl buying,” making the addition of 〈is〉 redundant; 〈is〉 should be deleted.

error_sentence: She see A little girl is buying some food, a young lady is looking at a dress, she's mother is trying the shoes.
correct_sentence: She sees a little girl buying some food, a young lady looking at a dress, and her mother trying on the shoes.
error: is

error_description: Word Redundancy Error: According to English grammar rules, when sense verbs (like see, watch, hear, etc.) are followed by an object and an object complement, to emphasize the ongoing nature of the action, the present participle must be used directly as the object complement, forming the standard structure “sense verb + object + present participle” (e.g., see sb. doing sth.). The phrase “sees... a young lady looking” already sufficiently expresses “seeing a young lady looking,” making the addition of 〈is〉 redundant; 〈is〉 should be deleted.

error_sentence: She see A little girl is buying some food, a young lady is looking at a dress, she's mother is trying the shoes.
correct_sentence: She sees a little girl buying some food, a young lady looking at a dress, and her mother trying on the shoes.
error: she's mother is trying
correction: and her mother trying on
error_type: Pronoun Error
error_severity: 5
error_description: ① Conjunction Error: In English parallel structures listing multiple items, the coordinating conjunction 『and』 must precede the final item for semantic connection; the original sentence only uses commas, lacking the conjunction, which disrupts structural integrity and logical coherence. ② Pronoun Error: 〈she's〉 is the contraction for “she is”; the intended meaning requires the possessive pronoun 『her』 to indicate possession (modifying ‘mother’). Using 〈she's〉 creates a redundant subject-verb structure and fails to convey the correct relationship. ③ Word Redundancy Error: According to English grammar rules for sense verbs (like see) followed by an object and object complement emphasizing ongoing action, the present participle is used directly (“sense verb + object + present participle”). The phrase “sees... and her mother trying” sufficiently expresses the meaning, making 〈is〉 redundant; it should be deleted. ④ Preposition Error: 〈trying〉 requires the preposition 『on』 to form the complete phrasal verb 『trying on』, indicating the action of trying on shoes.

error_sentence: He is staying on the sofa and waitting for she8
correct_sentence: He is staying on the sofa and waiting for her.
error: waitting for she8
correction: waiting for her.
error_type: Pronoun Error
error_severity: 5
error_description: ① Spelling Error: 〈waitting〉 should be 『waiting』, meaning “to wait”; for verbs ending in 't' preceded by a diphthong, the consonant is not doubled in the present participle form. ② Pronoun Error: The preposition 〈for〉 requires the objective case pronoun 『her』 (as its object), not the subjective case pronoun 〈she〉 (used only for subjects). ③ Other Error: The number 〈8〉 is an extraneous character and should be deleted as it does not conform to English writing standards. ④ Punctuation Error: The sentence 〈He is staying on the sofa and waiting for her〉 is complete and requires a period 『.』 at the end.
