error_type: Format Error
error_severity: 4
error_description: Format Error: According to English document layout rules, the title 〈Students Wanted for School Show〉, as a heading, must be visually separated from the main text by a line break. The original structure lacked a line break, weakening the title's function and confusing the document hierarchy. By inserting a line break 『\n』 at the end of the title, the incorrect layout is corrected to the standard format.

correct_sentence: Can you join the school show?
error: in
error_type: Preposition Error
error_severity: 2
error_description: Preposition Error: According to the usage rules for English transitive verbs, the verb 〈join〉 itself has the complete meaning of 'participate in/become a member of' and can directly take an object to form a verb-object structure. The incorrect addition of the preposition 〈in〉 in the original sentence violates the basic grammatical rule that transitive verbs directly take objects, creating the redundant and incorrect structure 'join in + object'. By deleting the redundant preposition 〈in〉, the incorrect expression 〈join in the school show〉 is corrected to the grammatically standard 『join the school show』.
error_sentence: The school show havesing , dance play the guitar , play the piano , play the violin and so on .
correct_sentence: The school show has singing, dancing, playing the guitar, playing the piano, playing the violin and so on.
error: havesing , dance play
correction: has singing, dancing, playing
error_type: PoS Confusion Error
error_severity: 5
error_description: ① Subject-Verb Agreement Error: The subject 〈The school show〉 is third-person singular; according to English grammar rules, the predicate verb must agree, so the plural verb 『have』 is changed to the singular verb 『has』, resulting in 『The school show has』; ② Space Error: According to English writing conventions, words must be separated by spaces. The original 〈havesing〉 should be changed to 『have singing』 to comply with correct written expression; ③ PoS Confusion Error: According to the sentence's meaning, the original sentence intends to express that 'the school show includes activities like singing, dancing, playing instruments, etc.', thus requiring noun forms rather than base verb forms. The verbs 〈sing〉, 〈dance〉, 〈play〉 are changed to the gerund forms 『singing』, 『dancing』, 『playing』 to correctly express the meaning of 'types of performances'; ④ Punctuation Error: According to English rules for listing parallel elements, multiple parallel nouns should be separated by commas. Therefore, a comma 『,』 is added in 〈dance play〉, and the phrase is ultimately corrected to 『singing, dancing, playing』, making the sentence structure clearer.
error_sentence: The school show havesing , dance play the guitar , play the piano , play the violin and so on .
correct_sentence: The school show has singing, dancing, playing the guitar, playing the piano, playing the violin and so on.
error: play
correction: playing
error_type: Nonfinite Verb Form Error
error_severity: 2
error_description: Nonfinite Verb Form Error: According to the principle of parallel structure in English, when multiple elements appear in parallel, they should maintain the same grammatical form. The previously corrected phrase 『singing, dancing, playing』 consists of gerunds (V-ing), while the second 〈play〉 is a base verb form, disrupting structural consistency. Therefore, the second 〈play〉 needs to be changed to the gerund form 『playing』 to make the overall structure parallel, i.e., 『singing, dancing, playing the guitar, playing the piano』.
error_sentence: The school show havesing , dance play the guitar , play the piano , play the violin and so on .
correct_sentence: The school show has singing, dancing, playing the guitar, playing the piano, playing the violin and so on.

error_description: Nonfinite Verb Form Error: According to the principle of parallel structure in English, when multiple elements appear in parallel, they should maintain the same grammatical form. The previously corrected phrase 『singing, dancing, playing the guitar, playing the piano』 consists of gerunds (V-ing), while the third 〈play〉 is a base verb form, disrupting structural consistency. Therefore, the third 〈play〉 needs to be changed to the gerund form 『playing』 to make the overall structure parallel, i.e., 『singing, dancing, playing the guitar, playing the piano, playing the violin』.

correct_sentence: If everyone can help us to have the school show, it will be very exciting.
error: evryone
correction: everyone
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: According to English spelling rules, 〈evryone〉 contains a letter sequence error; the correct spelling should be 『everyone』 to accurately convey the meaning 'every person', requiring the complete and correct sequence of letters.
error_sentence: If evryone can help us to have the school show , it will very excitement .
correct_sentence: If everyone can help us to have the school show, it will be very exciting.
error: very excitement
correction: be very exciting
error_type: PoS Confusion Error
error_severity: 4
error_description: ① Verb Choice Error: According to basic English sentence structure, the subject 〈it〉 requires the linking verb 『be』 to form a complete predicate. The original sentence lacks the linking verb, making the sentence structure incomplete; therefore, it is changed to 『will be』 after 〈it〉 to form the correct future tense expression 『it will be』; ② PoS Confusion Error: The original sentence uses the noun 〈excitement〉, which does not fit the intended meaning, as the sentence needs to express the adjectival meaning 'exciting'. According to English grammar rules, the noun 〈excitement〉 should be changed to the adjective 『exciting』 to correctly modify the subject 〈it〉 and ensure semantic coherence.
error_sentence: We hope the school show will give you happe .
correct_sentence: We hope the school show will give you happiness.
error: happe
correction: happiness
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: According to English word formation rules, 〈happe〉 is misspelled due to missing key letter combinations. The correct and complete form of the word should be derived from the adjective 'happy' plus the noun suffix '-ness', representing the abstract concept of 'happiness'; thus, it should be changed to 『happiness』.
