error_description: Punctuation Error: According to English punctuation rules, the abbreviation “p.m.” already includes a period to indicate its abbreviated form. The original sentence 〈p.m..〉 incorrectly adds a double period; therefore, the extra period needs to be removed, retaining the standard abbreviation 『p.m.』. This correction aligns with the Chicago Manual of Style's guidelines on punctuation for Latin abbreviations, ensuring professionalism and accuracy in time expression.

error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to the standard requirements for English sentence structure, when the negative word 〈No〉 is used at the beginning of a sentence to indicate a negative response, it must be followed by a comma to separate it from the main clause. The original sentence 〈No they are watching TV now.〉 lacks the necessary punctuation pause; therefore, a comma 『,』 needs to be added after 〈No〉, changing it to 『No, they are watching TV now.』, to make the sentence conform better to English writing conventions.
