Error analysis:
error_sentence: Hallo, everyone!
correct_sentence: Hello, everyone!
error: Hallo
correction: Hello
error_type: Spelling Error
error_severity: 1
error_description: Spelling Error: According to English writing conventions, the word 〈Hallo〉 is misspelled; the correct form should be 『Hello』, used for greeting.

error_sentence: She wear a shirt.
correct_sentence: She wears a shirt.
error: wear
correction: wears
error_type: Subject-Verb Agreement Error
error_severity: 3
error_description: Subject-Verb Agreement Error: According to English grammar rules, the verb must agree with the subject. Here the subject is the third-person singular 〈She〉, so the verb 〈wear〉 needs to be in the third-person singular form 『wears』.

error_sentence: And she take a piar of shoes.
correct_sentence: And she wears a pair of shoes.
error: take a piar
correction: wears a pair
error_type: Verb Choice Error
error_severity: 4
error_description: ① Verb Choice Error: According to English collocations, the verb 'wear' should be used to describe wearing shoes, not 〈take〉, so 〈take〉 is changed to 'wear'; ② Subject-Verb Agreement Error: Because the subject is the third-person singular 〈she〉, the verb must be in the third-person singular form, hence 『wears』 is used; ③ Spelling Error: According to English writing conventions, the word 〈piar〉 is misspelled; the correct form should be 『pair』, meaning 'a set of two'.

error_sentence: Ann likes it very much.
correct_sentence: Ann likes them very much.
error: it
correction: them
error_type: Pronoun Error
error_severity: 3
error_description: Pronoun Error: According to English grammar rules, pronouns must agree with their antecedents mentioned earlier. Here the antecedent 〈shoes〉 is a plural noun, so the pronoun must be in the plural form to refer to it; therefore, 〈it〉 is changed to 『them』 to ensure agreement in number between the pronoun and its antecedent.

error_sentence: She look at very beautiful.
correct_sentence: She looks very beautiful.
error: look at
correction: looks
error_type: Word Redundancy Error
error_severity: 4
error_description: ① Subject-Verb Agreement Error: According to English grammar rules, when the subject is third-person singular, the predicate verb must be in the third-person singular form. Here the subject is 〈She〉, so the verb 〈look〉 should be in the third-person singular form 『looks』; ② Word Redundancy Error: In the English subject-linking verb-predicative structure, linking verbs sometimes use sensory verbs like 'look, sound, smell, taste, feel' to describe sensory experiences. Here 『looks』 acts as a linking verb meaning 'appears', not an action verb, so the preposition 〈at〉 should be deleted.
