error_type: Punctuation Error
error_severity: 2
error_description: ① Case Error: According to English writing rules, the name “peter” is a proper noun, and its first letter should be capitalized. 〈peter〉 is written incorrectly and needs to be changed to 『Peter』 to conform to the writing standards; ② Punctuation Error: In English letters or daily communication greetings, a comma usually follows the salutation. In the original sentence “Hi peter I am lihua.”, a comma is missing between “Hi” and “Peter”; a comma 『,』 should be added to make the sentence punctuation correct.

correct_sentence: Hi Peter,
I am Li Hua.

correction: Li Hua
error_type: Case Error

In the original sentence, 〈lihua〉 is not written according to the standard and should be changed to 『Li Hua』 to present the name in the correct format.

error_type: Pronoun Error
error_severity: 3

correct_sentence: They can help you learn Chinese well.

error: to chinese
correction: Chinese
error_type: Preposition Error
error_severity: 2
error_description: ① Preposition Error: According to English grammar rules, when the verb 〈learn〉 is directly followed by a language name, the preposition 〈to〉 is not needed. In the original sentence, 〈to〉 is redundant and should be deleted, changing it to 『learn Chinese』 to make the expression grammatically correct; ② Case Error: “chinese” as a language name should have its first letter capitalized; it needs to be changed to 『Chinese』 so that the expression conforms to both grammar and writing conventions.
error_sentence: First you can attend chinese class.

correction: ,
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English grammar rules, when an ordinal number like 〈First〉 is placed at the beginning of a sentence to list items or indicate sequence, a comma 〈,〉 should be added after it to separate sentence components and make the sentence structure clearer, so 『,』 should be inserted.
error_sentence: First you can attend chinese class.
correct_sentence: First, you can attend a Chinese class.
error: chinese
correction: a Chinese
error_type: Determiner Error
error_severity: 2
error_description: ① Determiner Error: According to English grammar rules, the countable noun 〈class〉, when used in a general sense and in its singular form, requires an indefinite article “a” for determination. The original sentence lacks this determiner, which is grammatically incorrect, so 『a』 should be added; ② Case Error: According to English writing conventions, the first letter of the language name “chinese” should be capitalized. In the original sentence, 〈chinese〉 is written incorrectly and needs to be changed to 『Chinese』 to make the expression conform to standards;
error_sentence: You should watch chinese books and magazines and watch tv in english .

error_description: Case Error: According to English writing conventions, the first letter of the language name “chinese” should be capitalized. In the original sentence, 〈chinese〉 is written incorrectly and needs to be changed to 『Chinese』 to make the expression conform to standards.
error_sentence: You should watch chinese books and magazines and watch tv in english .

correct_sentence: You should watch Chinese books and magazines and watch TV in Chinese.

error: tv in english
correction: TV in Chinese
error_type: Noun Error
error_severity: 3
error_description: ① Case Error: In English, “tv” as an abbreviation for “television” should be written with a capitalized first letter according to standard practice. In the original sentence, 〈tv〉 is written incorrectly and should be changed to 『TV』 to comply with English writing rules; ② Noun Error: Semantically, the context of the original sentence is about learning Chinese, so one should watch Chinese programs rather than English programs. Therefore, 〈english〉 is used inappropriately and should be changed to 『Chinese』 to make the noun usage match the context.
error_sentence: You have to make friend in china this is most important thing .

correct_sentence: You have to make friends in China and this is the most important thing.

error: friend in china
correction: friends in China and
error_type: Conjunction Error
error_severity: 4
error_description: ① Noun Number Error: “make friends” is a fixed phrase meaning “to make friends”. Here it implies making multiple friends. 〈friend〉 is in the singular form, which does not fit the meaning, and should be changed to the plural form 『friends』; ② Case Error: “china” as a country name is a proper noun. According to English writing conventions, its first letter must be capitalized. In the original sentence, 〈china〉 is written incorrectly and should be changed to 『China』; ③ Conjunction Error: In the original sentence, “You have to make friend in china” and “this is most important thing” are two independent clauses. In English, they need to be connected by the conjunction 〈and〉 to make the sentence logically coherent and semantically complete.
error_sentence: You have to make friend in china this is most important thing .

correct_sentence: You have to make friends in China and this is the most important thing.

correction: the
error_type: Determiner Error
error_severity: 2
error_description: Determiner Error: In English, the definite article 〈the〉 is usually required before a superlative adjective. In the original sentence, 〈most important〉 is a superlative adjective modifying “thing”, and it lacks the definite article. 『the』 should be added to make the expression grammatically correct.
error_sentence: Yes you should sing chinese songs everday .
correct_sentence: Yes, you should sing Chinese songs everyday.
correction: ,
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English grammar rules, when an interjection like “ Yes” is placed at the beginning of a sentence, a comma 〈,〉 should be added after it to separate the interjection from the main clause content, making the sentence structure clearer and the semantic expression more precise. Therefore, 『,』 should be inserted in the original sentence.

error_type: Word Redundancy Error
error_severity: 4
error_description: ① Case Error: According to English writing conventions, the first letter of a language name needs to be capitalized. 〈chinese〉 as a language name means “Chinese,” so 〈chinese〉 needs to be changed to 『Chinese』 to conform to standards; ② Spelling Error: According to the sentence meaning, the intention here is to express “everyday.” Therefore, 〈everday〉 is a misspelling of 『everyday』 and needs to be changed to 『everyday』 to make the sentence meaning coherent; ③ Word Redundancy Error: According to English grammar rules, the structure of 〈Tt's help〉 in the original sentence is confused, “'s” is redundant and does not conform to English expression habits; it needs to be changed to 『It helps』 to comply with grammar rules; ④ Subject-Verb Agreement Error: According to English grammar rules, in the simple present tense, when the subject is the third-person singular 〈It〉, the predicate verb needs to be in the third-person singular form. Therefore, 〈help〉 needs to be changed to 『helps』.
error_sentence: Tt's help you learn chinese well
I hope you make great progress in the study chinese
Wating for you letter.

error: chinese well
correction: Chinese well.
error_type: Case Error
error_severity: 1
error_description: ① Case Error: According to English writing conventions, the first letter of a language name needs to be capitalized. 〈chinese〉 as a language name means “Chinese,” so 〈chinese〉 needs to be changed to 『Chinese』 to conform to standards; ② Punctuation Error: According to English grammar rules, a sentence needs to end with a punctuation mark after expressing a complete idea. The original phrase 〈chinese well〉 lacks a period at the end; 『.』 needs to be added after it for correct sentence division.

I hope you make great progress in the study chinese
Wating for you letter.

error_type: Nonfinite Verb Form Error
error_severity: 3
error_description: ① Nonfinite Verb Form Error: According to English grammar rules, the preposition 〈in〉 should be followed by a gerund as its object. The original phrase 〈the study〉 is grammatically incorrect and needs to be changed to the gerund form 『studying』 to comply with grammar rules; ② Case Error: According to English writing conventions, the first letter of a language name needs to be capitalized. 〈chinese〉 as a language name should be changed to 『Chinese』 to conform to standards; ③ Spelling Error: According to the sentence meaning, the intention here is to express “waiting.” Therefore, 〈Wating〉 is a misspelling of 『Waiting』 and needs to be changed to 『Waiting』 to make the sentence meaning coherent; ④ Pronoun Error: According to the sentence meaning, the possession of the letter needs to be indicated here. Therefore, 〈you〉 should be changed to its possessive form 『your』 to correctly express “your letter”.
