error_description: ① Spelling Error: According to English writing conventions, the correct English spelling for Chinese names is: surname Pinyin first with the initial letter capitalized, followed by a space, then the given name Pinyin with the initial letter also capitalized. If the given name consists of two characters, their Pinyin should be written together without a space, with only the initial letter of the first character's Pinyin capitalized. Therefore, 〈peng si han〉 is misspelled and should be 『Peng Sihan』; ② Space Error: There should be no space between "han" and the following period, so the space is deleted; ③ Case Error: According to English writing conventions, the first letter of the first word in a sentence must be capitalized. Since "this is my friend ..." is an independent sentence, the first letter of the first word needs to be capitalized. Therefore, 〈this〉 is changed to 『This』 to conform to English writing standards.

correct_sentence: This is my friend Chen Yegia. She is very happy today.
error: chen ye gia. she
correction: Chen Yegia. She

error_sentence: she is very happy on today, she is wear a bright red shirt, she is very like this color, and she is wear a pair of black shoes.
correct_sentence: She is very happy today. She wears a bright red shirt, and she likes this color very much, and she wears a pair of black shoes.
error: on today, she is wear
correction: today. She wears
error_type: Verb Tense Error
error_severity: 4
error_description: ① Preposition Error: In English, "today" is generally not preceded by a preposition, so "on" in 〈on today〉 should be deleted to conform to English expression habits; ② Punctuation Error: "She is very happy today" and the following "She wears..." are two independent sentences and should be separated by a period. Therefore, the comma after "today" is changed to a period; ③ Verb Tense Error: Based on the context, 〈she is wear〉 should be changed to the simple present tense, third-person singular form 『She wears』.

error_sentence: she is very happy on today, she is wear a bright red shirt, she is very like this color, and she is wear a pair of black shoes.
correct_sentence: She wears a bright red shirt, and she likes this color very much, and she wears a pair of black shoes.
error: she is very like
correction: and she likes
error_type: Subject-Verb Agreement Error
error_severity: 4
error_description: ① Conjunction Error: Actions in a compound sentence need to be connected by a conjunction for fluency, so 『and』 is added at the beginning of the clause; ② Auxiliary Error: In 〈is very like〉, "is" and "like" are incorrectly paired; "is" is mistakenly used in the simple present tense and should be deleted; ③ Adverb Error: "very" as an adverb of degree cannot modify the verb "like", so "very" is deleted; ④ Subject-Verb Agreement Error: The subject of the sentence is the third-person singular "she", so the predicate verb must be in the third-person singular form; 〈like〉 needs to be changed to 『likes』.

error_sentence: she is very happy on today, she is wear a bright red shirt, she is very like this color, and she is wear a pair of black shoes.
correct_sentence: She wears a bright red shirt, and she likes this color very much, and she wears a pair of black shoes.
correction: very much
error_type: Word Order Error
error_severity: 3
error_description: Word Order Error: In English, the adverbial phrase 〈very like〉 is an incorrect expression; the word order should be adjusted to “likes...very much”, placing the adverb of degree 『very much』 at the end of the clause.

error_sentence: she is very happy on today, she is wear a bright red shirt, she is very like this color, and she is wear a pair of black shoes.
correct_sentence: She wears a bright red shirt, and she likes this color very much, and she wears a pair of black shoes.
error: is wear
correction: wears
error_type: Verb Tense Error
error_severity: 3
error_description: Verb Tense Error: Based on the context, 〈is wear〉 incorrectly uses the present continuous structure; it should be changed to the simple present tense, third-person singular form 『wears』 to indicate a habitual action, agreeing with the third-person singular subject "she".

error_sentence: I also very lovely.
correct_sentence: I am also very lovely.
correction: am
error_type: Sentence Structure Error
error_severity: 3
error_description: Sentence Structure Error: In the sentence 〈I also very lovely〉, the subject 〈I〉 requires the linking verb 『am』 to form a complete 'subject-verb-complement' structure; therefore, 『am』 is added to make the sentence grammatically correct.
