correct_sentence: At three p.m., Linda is in a shopping mall.
error: p.m
correction: p.m.
error_type: Spelling Error
error_severity: 2
error_description: ① Spelling Error: According to English writing conventions, the time abbreviation 'p.m.' is an acronym and requires a period at the end according to standard rules. The original sentence lacks the period after 〈p.m〉, which is a spelling error. Therefore, 〈p.m〉 should be changed to 『p.m.』 to comply with English punctuation standards.

error_sentence: A young lady is looking at the dress.
correct_sentence: A young lady is looking at a dress.
error: the
correction: a
error_type: Determiner Error
error_severity: 2
error_description: ① Determiner Error: According to English grammar rules, the definite article 'the' is used to specify a particular item, while the indefinite article 'a' is used to refer generally to one item of a category. In this sentence, considering the context, it describes a young lady looking at any dress, not a specific known one, thus it should be a general reference. Using 〈the〉 in the original sentence is a determiner error; it needs to be changed to the indefinite article 『a』 to fit the context.

error_sentence: Linda's mother is trying a pair of shoes.
correct_sentence: Linda's mother is trying on a pair of shoes.
correction: on
error_type: Preposition Error
error_severity: 3
error_description: ① Preposition Error: According to English grammar rules, 'try on' is a fixed phrase meaning 'to put on clothing to see if it fits', and the preposition 'on' is essential. The original sentence lacks the required preposition 〈on〉 after 〈trying〉, which is a preposition error. Therefore, 『on』 needs to be added after 〈trying〉 to meet the requirement of the fixed phrase 'try on'.

error_sentence: He is staying on the sofa, reading a newspaper and waiting for Linda's mother.
correct_sentence: He is staying on the sofa, reading a newspaper, and waiting for Linda's mother.
correction: ,
error_type: Punctuation Error
error_severity: 2
error_description: ① Punctuation Error: According to English punctuation rules, in a parallel structure, a comma should be used to separate items in a series. The original sentence has parallel actions 〈reading a newspaper〉 and 〈waiting〉; a comma is needed after 〈reading a newspaper〉. Therefore, 『,』 should be added after 〈reading a newspaper〉 to comply with parallel structure punctuation rules.
