error_type: Punctuation Error
error_severity: 2
error_description: ① Punctuation Error: According to English grammar rules, two independent clauses cannot be connected by a comma, a period must be used. "My name is Z" and "I am not opposition to students bring mobile phone to school" are two independent sentences, each with its own independent subject-verb structure, so a period should be used for separation, changing 〈Z,〉 to 『Z.』.
error_sentence: My name is Z, I am not opposition to students bring mobile phone to school.
correct_sentence: I am not opposed to students bringing mobile phones to school.
error: opposition
correction: opposed
error_type: PoS Confusion Error
error_severity: 4
error_description: ① PoS Confusion Error: According to English grammar rules, in a “be + predicative” structure, an adjective is needed as the predicative to describe the state of the subject. In the original sentence, "opposition" is a noun and cannot be a predicative here; it should be changed to the adjective 『opposed』; ② Preposition Error: "be opposed to" is a fixed phrase meaning “to object to”. When changing the noun “opposition” to the adjective "opposed" in the original sentence, the preposition 〈to〉 must be retained to ensure the correct phrase structure.
error_sentence: My name is Z, I am not opposition to students bring mobile phone to school.
correct_sentence: I am not opposed to students bringing mobile phones to school.
error: bring mobile phone
correction: bringing mobile phones
error_type: Nonfinite Verb Form Error
error_severity: 3
error_description: ① Nonfinite Verb Form Error: According to English grammar rules, if a verb follows the preposition 〈to〉, the gerund form is required. In the original sentence, 〈bring〉 in "students bring mobile phone to school" is in its base form, which does not meet grammatical requirements; 〈bring〉 should be changed to the gerund form 『bringing』; ② Noun Number Error: "mobile phone" is a countable noun, and in this context, it refers to the general act of students bringing mobile phones, so the plural form should be used. In the original sentence, the form 〈mobile phone〉 is incorrect and needs to be changed to 『mobile phones』 to make the expression conform to context and grammatical rules.
error_sentence: Because mobile phone is convenient that we can use it to make communication to our parents and friends, and it gives our great delight.
correct_sentence: Because mobile phones are so convenient that we can use them to communicate with our parents and friends, and they give us great delight.

correction: phones are so
error_type: Subject-Verb Agreement Error
error_severity: 3
error_description: ① Subject-Verb Agreement Error: In the original sentence, "mobile phone" is a plural concept in context, referring to mobile phones in general. The predicate verb cannot be in the singular form "is"; according to English grammar rules, the predicate verb should be changed to the plural form 『are』; ② Adverb Error: To make the sentence structure more complete and the meaning clearer, the degree adverb 〈so〉 needs to be added to modify the adjective 〈convenient〉, forming a "so...that" structure to enhance the tone of expression.
error_sentence: Because mobile phone is convenient that we can use it to make communication to our parents and friends, and it gives our great delight.
correct_sentence: Because mobile phones are so convenient that we can use them to communicate with our parents and friends, and they give us great delight.
error: it to make communication to
correction: them to communicate with
error_type: Verb Choice Error
error_severity: 3
error_description: ① Pronoun Error: In the original sentence, "it" refers to the plural noun "phones". According to English grammar rules, a plural pronoun 『them』 should be used to refer to a plural noun, so 〈it〉 needs to be changed to 『them』; ② Verb Choice Error: The expression "make communication to" does not conform to English usage. "communicate" itself means “to exchange information, to talk”, which is more concise and accurate; 〈make communication〉 should be changed to 『communicate』; ③ Preposition Error: "communicate" forms a fixed phrase "communicate with", meaning “to exchange information with...”. The preposition in the original sentence is used incorrectly; 〈with〉 should be retained to make the expression conform to English usage.
error_sentence: Because mobile phone is convenient that we can use it to make communication to our parents and friends, and it gives our great delight.
correct_sentence: Because mobile phones are so convenient that we can use them to communicate with our parents and friends, and they give us great delight.
error: it gives our
correction: they give us
error_type: Pronoun Error
error_severity: 3
error_description: ① Pronoun Error: In the original sentence, "it" refers to the plural noun "phones". In English, the nominative pronoun referring to a plural noun should be in plural form, so 〈it〉 should be changed to the plural nominative pronoun 『they』 to match the plural subject "mobile phones"; "gives" is a transitive verb and should be followed by an objective pronoun as its object. "our" is a possessive pronoun and cannot be an object here; 〈our〉 should be changed to the objective pronoun 『us』, conforming to the requirements of person and case in English grammar.
error_sentence: There are also having some problems when we bring mobile phone to school, we disturb teachers and students while we use mobile phone, chating and writing message in mobile phone wastes time and money, mobile phone is serious harmful to our when we playing games and cheating in examinations.
correct_sentence: There are also some problems when we bring mobile phones to school.
error: having
error_type: Word Redundancy Error
error_severity: 4
error_description: ① Word Redundancy Error: According to English grammar rules, "There are" is a common structure for expressing “existence”. "having" is redundant here; "There are having" is an incorrect expression. Using 『There are』 directly can fully convey the meaning of existence, so the redundant 〈having〉 should be deleted to make the sentence concise and correct.
error_sentence: There are also having some problems when we bring mobile phone to school, we disturb teachers and students while we use mobile phone, chating and writing message in mobile phone wastes time and money, mobile phone is serious harmful to our when we playing games and cheating in examinations.

correction: phones
error_type: Noun Number Error
error_severity: 3
error_description: ① Noun Number Error: "phone" is a countable noun. In this sentence, it generally refers to the common situation of students bringing mobile phones to school, not a specific mobile phone. According to English grammar rules, countable nouns usually take the plural form when used in a general sense, so 〈phone〉 should be changed to the plural form 『phones』 to ensure consistency in expression with the context.

error_type: Punctuation Error
error_severity: 2
error_description: ① Punctuation Error: According to English grammar rules, two independent sentences must be separated by a period. "There are also having some problems when we bring mobile phones to school" and "we disturb teachers and students while we use mobile phone" are two independent clauses, each with a complete subject-verb structure. Two independent clauses cannot be directly connected by a comma; 〈, we〉 should be changed to 『. We』, using a period to separate the two sentences, making the sentence structure clear and compliant with norms.

error_type: Nonfinite Verb Form Error
error_severity: 3
error_description: ① Nonfinite Verb Form Error: According to English grammar rules, the conjunction 〈while〉 is often followed by a present participle phrase as an adverbial of time. The expression "while we use mobile phone" in the original sentence does not conform to this rule; 〈we use〉 should be changed to the present participle form 『using』 to make the sentence structure correct; ② Noun Number Error: "phone" is a countable noun. In this context, it refers to the general situation of students using mobile phones and should be in plural form. The form 〈phone〉 in the original sentence is incorrect and needs to be changed to 『phones』 to make the expression conform to context and grammatical rules; ③ Spelling Error: According to the meaning of the sentence, it is clear that the intention here is to express “chatting”. Therefore, 〈chating〉 is a misspelling of 『chatting』; 〈chating〉 needs to be corrected to 『chatting』 to make the sentence meaningful.
error_sentence: There are also having some problems when we bring mobile phone to school, we disturb teachers and students while we use mobile phone, chating and writing message in mobile phone wastes time and money, mobile phone is serious harmful to our when we playing games and cheating in examinations.
correct_sentence: We disturb teachers and students while using mobile phones, chatting and writing messages on mobile phones waste time and money, and mobile phones are seriously harmful to us when we play games and cheat in examinations.

error_type: Noun Number Error
error_severity: 3
error_description: ① Preposition Error: In common English expressions, when performing operations on electronic devices (such as mobile phones), the preposition 〈on〉 should be used, whereas using 〈in〉 in the original sentence is incorrect; it needs to be changed to 〈on〉; ② Noun Number Error: "message" and "phone" are both plural concepts in this context. "message" refers to multiple messages, and "phone" refers to multiple mobile phones, so 〈message〉 and 〈phone〉 should be changed to their plural forms 『messages』 and 『phones』 respectively; simultaneously, as the subject corresponding to the verb “wastes” in the original sentence becomes the plural "messages", the verb should also be changed to the form corresponding to a plural subject, 『waste』.
error_sentence: There are also having some problems when we bring mobile phone to school, we disturb teachers and students while we use mobile phone, chating and writing message in mobile phone wastes time and money, mobile phone is serious harmful to our when we playing games and cheating in examinations.

error: mobile phone is serious
correction: and mobile phones are seriously
error_type: Conjunction Error
error_severity: 4
error_description: ① Conjunction Error: The original sentence lacks a conjunction between multiple parallel components. According to English grammar rules, the conjunction 『and』 needs to be added before 〈mobile phone〉 to connect the preceding and succeeding meanings, making the sentence logically coherent; ② Noun Number Error: "mobile phone" in this context refers to multiple mobile phones in general, which is a plural concept. According to grammatical requirements, countable nouns in such cases need to be in plural form; 〈mobile phone〉 should be changed to 『mobile phones』; ③ Adverb Error: "harmful" is an adjective, and an adverb should be used to modify an adjective. In the original sentence, "serious" is an adjective and cannot be used to modify "harmful"; 〈serious〉 should be changed to the adverb form 『seriously』. Therefore, 〈mobile phone is serious〉 needs to be changed to 『and mobile phones are seriously』.
error_sentence: There are also having some problems when we bring mobile phone to school, we disturb teachers and students while we use mobile phone, chating and writing message in mobile phone wastes time and money, mobile phone is serious harmful to our when we playing games and cheating in examinations.

error_description: ① Pronoun Error: According to English grammar rules, the preposition 〈to〉 needs to be followed by an objective pronoun as its object.
