error_severity: 3
error_description: Conjunction Error: According to English grammar rules, the clauses 〈Linda is in a shopping hall〉 and 〈she sees a little girl is buying some food〉 in the original sentence are coordinate clauses.

The conjunction 『and』 should be added after 『shopping hall』 to connect the clauses, making the sentence structure correct and the meaning coherent.

error_type: Punctuation Error
error_severity: 3
error_description: ① Punctuation Error: According to English grammar rules, two independent clauses cannot be joined solely by a comma, as this causes sentence structure confusion. In the original sentence, 〈Linda is in a shopping hall〉 and 〈she sees a little girl is buying some food〉 are two independent clauses and cannot be connected by a comma. 〈, she〉 should be changed to 『. She』, using a period to separate the two independent clauses, making the sentence structure correct; ② Case Error: According to English writing rules, the first letter of the first word in a sentence must be capitalized. In the original sentence, the subject 〈she〉 of the subsequent clause 〈she sees a little girl is buying some food〉 is at the beginning of the sentence, and its first letter should be capitalized. The lowercase 〈she〉 should be changed to uppercase 『She』 to comply with English writing conventions.
