error_type: Sentence Structure Error
error_severity: 5
error_description: ① Spelling Error: The word 〈sweter〉 is misspelled; the correct spelling is 『sweaters』. The phrase 〈thiry doller〉 has two spelling errors and should be corrected to 『thirty dollars』, note the -ir- order in thirty; ② Noun Number Error: Based on context and common usage for quantities, 〈sweter〉 should be plural 『sweaters』, and 〈doller〉 should be plural 『dollars』 to match the context of general reference or bulk sales of goods; ③ Sentence Structure Error: According to basic English sentence patterns, the original sentence lacks a predicate verb, making it incomplete; therefore, 『sell for』 needs to be added to form a complete 'subject + verb + object' structure.
