error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: According to English writing conventions for Chinese names, the first letter of the surname's pinyin should be capitalized, and the pinyin for a two-character given name should be written together with the first letter of the first character's pinyin capitalized. Here, the name 〈wan yu〉 is misspelled and should be changed to 『Wanyu』 to comply with the English spelling rules for Chinese names.

error_sentence: She like is blue.
correct_sentence: She likes blue.
error: like is
correction: likes
error_type: Sentence Structure Error
error_severity: 3
error_description: Sentence Structure Error: According to English grammar rules, a simple sentence can only contain one predicate verb. 〈She like is blue〉 contains two predicate verbs, which is an incorrect sentence structure, so <is> should be removed. Because the subject 〈She〉 is third-person singular, the verb needs to be in the third-person singular form. The verb 〈like〉 lacks the -s suffix, so it should be changed to 『likes』 to satisfy subject-verb agreement rules.

error_sentence: She is a blue shirt wear, a white shoes.
correct_sentence: She is wearing a blue shirt and white shoes.
correction: wearing
error_type: Word Order Error
error_severity: 4
error_description: ① Word Order Error: According to English grammar rules, describing the state of wearing should use the progressive tense, not the noun phrase 〈shirt wear〉. Therefore, 〈is a blue shirt wear〉 should be changed to 『is wearing a blue shirt』; ② Nonfinite Verb Form Error: The verb 〈wear〉 in the sentence needs to be in the present progressive form to describe an ongoing action, so 〈wear〉 should be changed to 『wearing』 to comply with grammar rules.

error_sentence: She is a blue shirt wear, a white shoes.
correct_sentence: She is wearing a blue shirt and white shoes.
error: wear, a
correction: and
error_type: Conjunction Error
error_severity: 4
error_description: ① Conjunction Error: The two parallel noun phrases 〈a blue shirt〉 and 〈a white shoes〉 in the sentence both serve as objects of the verb 'wear' and need a conjunction to connect them. Therefore, 〈wear, a〉 should be replaced with 『and』 to maintain coherence; ② Determiner Error: In 〈a white shoes〉, 〈shoes〉 is plural, meaning 'a pair of shoes', so it should not be paired with the singular determiner 〈a〉. Therefore, 〈a〉 should be removed.

error_sentence: Sheis beautiful.
correct_sentence: She is beautiful.
error: Sheis
correction: She is
error_type: Space Error
error_severity: 1
error_description: Space Error: According to English writing conventions, the phrase 〈Sheis〉 lacks the necessary space, causing the two words 〈She〉 and 〈is〉 to be joined together. Therefore, a space should be added between 〈She〉 and 〈is〉 to form 『She is』, conforming to standard writing format.
