error_type: Nonfinite Verb Form Error
error_severity: 5
error_description: ① Subject-Verb Agreement Error: The third-person singular subject 〈friend〉 requires the third-person singular form of the verb, 『likes』; therefore, 〈like〉 needs to be changed to 『likes』 to comply with the English subject-verb agreement rule; ② Nonfinite Verb Form Error: In English, "like to do something" is commonly used to express "enjoy doing something"; therefore, the verb 〈wear〉 following "like" as an object needs to be in the infinitive form 『to wear』; ③ Determiner Error: As a countable noun, 〈shirt〉 in its singular form requires a determiner; the context means "the friend likes to wear a red shirt", so according to the semantics, the indefinite article 『a』 needs to be added before 〈red〉 to comply with English grammar rules.

error_sentence: Because he think very beautiful.
correct_sentence: Because he thinks it is very beautiful.
error: think
correction: thinks it is
error_type: Sentence Structure Error
error_severity: 5
error_description: ① Subject-Verb Agreement Error: The subject 〈he〉 is third-person singular, so the predicate verb 〈think〉 needs to be in the third-person singular form 『thinks』 to comply with subject-verb agreement grammar; ② Sentence Structure Error: 〈very beautiful〉 is a component of the object clause following 〈think〉; therefore, the subject and linking verb 『it is』 need to be added before 〈very〉 to form a complete subject-predicate-object structure as the object clause for 〈think〉.

error_sentence: And he likes wear pule white shoe.
correct_sentence: And he likes to wear purple and white shoes.
error: wear pule white shoe
correction: to wear purple and white shoes
error_type: Conjunction Error
error_severity: 5
error_description: ① Nonfinite Verb Form Error: In English, "like to do something" is commonly used to express "enjoy doing something"; the verb 〈wear〉 needs to be in the infinitive form 『to wear』 to comply with English grammar rules; ② Spelling Error: The word 〈pule〉 here is the adjective "purple", which is misspelled; it should be changed to 『purple』; ③ Conjunction Error: In English, two parallel adjectives in a sentence need to be connected by the conjunction "and"; therefore, 『and 』 needs to be added before 〈white〉 to comply with English grammar rules; ④ Noun Number Error: The meaning here is "the friend likes to wear purple and white shoes"; therefore, the countable noun 〈shoe〉 needs to be in the plural form 『shoes』 to match the meaning.

error_sentence: He think very pretty.
correct_sentence: He thinks they are very pretty.
error: think
correction: thinks they are
error_type: Sentence Structure Error
error_severity: 5
error_description: ① Subject-Verb Agreement Error: The subject 〈he〉 is third-person singular, so the predicate verb 〈think〉 needs to be in the third-person singular form 『thinks』 to comply with the subject-verb agreement principle; ② Sentence Structure Error: 〈very pretty〉 is a component of the object clause following 〈think〉; therefore, a subject and linking verb need to be added before 〈very〉 to form a complete subject-predicate-object structure as the object clause for 〈think〉. According to the preceding text, this refers to "the friend thinks the purple and white shoes are very pretty", so the subject of the object clause refers to the preceding plural noun 『shoes』; thus, the subject and linking verb 『they are』 should be added before 〈very pretty〉.

error_sentence: I very like his shirt and shoe.
correct_sentence: I like his shirt and shoes very much.
error: very
error_type: Word Order Error
error_severity: 3
error_description: Word Order Error: When the adverb 〈very〉 modifies the verb 〈like〉, it should be placed at the end of the sentence using the structure 『like something very much』; therefore, there is a word order error here. The sentence order should be adjusted to 『I like...very much』, which requires deleting 〈very 〉 and adding 『very much』 after 〈shoe〉.

error_sentence: I very like his shirt and shoe.
correct_sentence: I like his shirt and shoes very much.
error: shoe
correction: shoes very much
error_type: Noun Number Error
error_severity: 3
error_description: Noun Number Error: According to the preceding text, this refers to "the friend likes his shirt and shoes very much". The shoes here are definitely more than one; therefore, there is a noun number error here. The countable noun 〈shoe〉 needs to be in the plural form 『shoes』 to match the preceding context's semantics.
