error_type: Word Order Error
error_severity: 3
error_description: ① Word Order Error: The fixed English noun phrase structure is 『plan for next weekend』, meaning 'plan about next weekend'. The original sentence has a word order error; 〈next weekend plan〉 should be changed to 『plan for next weekend』 to conform to the fixed English collocation; ② Preposition Error: When expressing 'plan for...', the noun 'plan' should be followed by the preposition 『for』 and then a noun to form a possessive relationship; therefore, it needs to be changed to 『plan for next weekend』 to conform to English morphological structure.
error_sentence: This is Tom's next weekend plan.
correct_sentence: This is Tom's plan for next weekend.
error: plan
error_type: Word Redundancy Error
error_severity: 3
error_description: Word Redundancy Error: The fixed English collocation 'plan for + noun' means 'plan for xxx'. After 'plan', the prepositional phrase introduced by 'for' acts as a post-modifier explaining 'plan'. After adjusting the word order in the previous sentence, 〈plan〉 in 〈next weekend plan〉 needs to be deleted to conform to the fixed English collocation.
error_sentence: On Saterday, Tom is going to do his homework at nine thirty, going to watch TV at eleven o'clock .
correct_sentence: On Saturday, Tom is going to do his homework at nine thirty and watch TV at eleven o'clock.
error: Saterday
correction: Saturday
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: The English proper noun for 'Saturday', 〈Saterday〉, has a clear spelling error. It should be changed to 『Saturday』 to comply with English spelling rules.
error_sentence: On Saterday, Tom is going to do his homework at nine thirty, going to watch TV at eleven o'clock .
correct_sentence: On Saturday, Tom is going to do his homework at nine thirty and watch TV at eleven o'clock.

correction: and
error_type: Conjunction Error
error_severity: 5
error_description: ① Conjunction Error: The two verb phrases 〈do his homework〉 and 〈watch TV〉 share the auxiliary 'going to', so 'going to' should only appear once. They need to be connected by the conjunction 『and』; 〈going to〉 should be changed to 『and』 to comply with English syntax rules; ② Punctuation Error: When 'and' connects two parallel verb phrases in a sentence, a comma is not needed; therefore, the comma 〈,〉 should be deleted here to comply with English syntax rules.
error_sentence: On Sunday , Tom is going to cleaning his room at ten o'clock.
correct_sentence: On Sunday, Tom is going to clean his room at ten o'clock, play basketball at 14:00, and have a bath at six pm.
error: cleaning
correction: clean
error_type: Nonfinite Verb Form Error
error_severity: 3
error_description: Nonfinite Verb Form Error: In English, the structure 〈be going to〉 should be followed by the base form of the verb. Therefore, there is a nonfinite verb form error here; the gerund 〈cleaning〉 needs to be changed to the base form 『clean』 to comply with English grammar rules.
error_sentence: On Sunday , Tom is going to cleaning his room at ten o'clock. going to play basketball at 14:00 and going to have a bath at six o'clock p.m..
correct_sentence: On Sunday, Tom is going to clean his room at ten o'clock, play basketball at 14:00, and have a bath at six pm.
error: . going to
correction: ,
error_type: Word Redundancy Error
error_severity: 5
error_description: ① Punctuation Error: Multiple parallel verb phrases within the same sentence should be separated by commas. Therefore, there is a punctuation error here; the period 〈.〉 should be changed to a comma 『,』 to connect the different verb phrases, forming a coherent compound sentence structure which better conforms to English syntax rules; ② Word Redundancy Error: The several parallel verb phrases here can share the auxiliary 'going to', making repetition unnecessary. Therefore, the redundant 〈going to〉 (before 'play basketball') needs to be deleted to conform to standard English expression.
error_sentence: going to play basketball at 14:00 and going to have a bath at six o'clock p.m..
correct_sentence: On Sunday, Tom is going to clean his room at ten o'clock, play basketball at 14:00, and have a bath at six pm.
error: and going to
correction: , and
error_type: Word Redundancy Error
error_severity: 5
error_description: ① Word Redundancy Error: 〈play basketball〉 and 〈have a bath〉 are the last two of three parallel verb phrases appearing in the same sentence. The three parallel verb phrases can share the auxiliary 'going to', so the 〈going to〉 before 〈have a bath〉 is redundant and should be deleted; ② Punctuation Error: The clause introduced by 〈have a bath〉, being the last of three parallel clauses, should be separated from the preceding clause by a comma when placed at the end of the sentence; therefore, a comma 『, 』 should be added before 〈and〉 to comply with English syntax rules.
error_sentence: going to play basketball at 14:00 and going to have a bath at six o'clock p.m..
correct_sentence: On Sunday, Tom is going to clean his room at ten o'clock, play basketball at 14:00, and have a bath at six pm.
error: o'clock p.m..
correction: pm.
error_type: Word Redundancy Error
error_severity: 5
error_description: ① Word Redundancy Error: In English expression, 〈o'clock〉 and 〈p.m.〉 cannot be used simultaneously. According to the prompt, the time here is 'six o'clock in the afternoon' (18:00), so 〈o'clock〉 should be deleted, keeping 『six p.m.』 to match the original meaning; ② Punctuation Error: Double periods cannot be used at the end of a sentence; one period should be deleted, ending with 『pm.』 to comply with English syntax rules.
