Error analysis:
error_sentence: On saturday, At9: 30 a.m. Tom will do his homework.
correct_sentence: At 9:30 a.m. on Saturday, Tom will do his homework.
error: On saturday, At9: 30 a.m.
correction: At 9:30 a.m. on Saturday,
error_type: Word Order Error
error_severity: 5
error_description: ① Case Error: According to English writing conventions, days of the week are proper nouns and their first letter should be capitalized. In the original sentence, the first letter of 〈saturday〉 is not capitalized, which is a case error; it should be changed to 『Saturday』; ② Space Error: In English time expressions, a space is needed between the preposition and the number. The original phrase 〈At9: 30〉 lacks a space, which is a space error; it should be changed to 『At 9:30』; ③ Word Order Error: According to English grammar rules and expression habits, if a time adverbial includes specific time and day information, placing the specific time before the day and at the beginning of the sentence is more idiomatic. The order of the time adverbial 〈On saturday, At9: 30 a.m.〉 in the original sentence is incorrect; it should be adjusted to 『At 9:30 a.m. on Saturday』 to make the word order of the time adverbial conform to English norms.

error_sentence: At 11:00 a.m. Tom will watch TV.
correct_sentence: At 11:00 a.m., Tom will watch TV.
correction: ,
error_type: Punctuation Error
error_severity: 2
error_description: ① Punctuation Error: According to English grammar rules and writing conventions, a comma is usually needed to separate a time adverbial from the main clause to clearly divide the sentence structure. In the original sentence, there is no comma separating the time adverbial 〈At 11:00 a.m.〉 from the main clause “Tom will watch TV.”, which is a punctuation error. Therefore, a comma needs to be added after 〈At 11:00 a.m.〉, changing it to 『At 11:00 a.m., Tom will watch TV.』, to make the sentence conform to English writing conventions.

error_sentence: He go to the parkin the afternoon.
correct_sentence: He will go to the park in the afternoon.
correction: will
error_type: Auxiliary Error
error_severity: 3
error_description: ① Auxiliary Error: According to English grammar rules, the simple future tense requires the auxiliary verb “will” + the base form of the verb to form the predicate structure, indicating an action that will happen in the future. In the original sentence, the subject “He” is third-person singular, and when expressing a future action, the auxiliary verb “will” is missing before the predicate verb “go”, resulting in an incorrect tense expression, which is an auxiliary error. Therefore, the auxiliary verb 『will』 needs to be added before 〈go〉 to conform to the grammatical structure of the simple future tense.

error_sentence: He go to the parkin the afternoon.
correct_sentence: He will go to the park in the afternoon.
error: parkin
correction: park in
error_type: Space Error
error_severity: 1
error_description: ① Space Error: According to English writing conventions, words must be correctly separated by spaces to ensure clear meaning. In the original sentence, the word 〈parkin〉 lacks a necessary space, causing semantic confusion and making it impossible to clearly distinguish the place “park” from the time adverbial “in the afternoon”, which is a space error. Therefore, 〈parkin〉 needs to be changed to 『park in』 to make the sentence structure clear and conform to English writing requirements.

error_sentence: On sunday, he will clean his home at 10:00.
correct_sentence: On Sunday, he will clean his room at 10:00.
error: sunday
correction: Sunday
error_type: Case Error
error_severity: 1
error_description: ① Case Error: According to English writing conventions, days of the week are proper nouns, and the first letter of a proper noun must be capitalized. In the original sentence, 〈sunday〉, being a day of the week, does not have its first letter capitalized, which violates English writing rules and is a case error. Therefore, 〈sunday〉 should be changed to 『Sunday』 to make the sentence conform to the writing conventions for English proper nouns.

error_sentence: On sunday, he will clean his home at 10:00.
correct_sentence: On Sunday, he will clean his room at 10:00.
error: home
correction: room
error_type: Noun Error
error_severity: 3
error_description: ① Noun Error: According to Tom's activity information in the prompt, when describing the activity "On Sunday", the object being cleaned should be "room". The use of 〈home〉 in the original sentence does not fit the given context and is a noun error. Therefore, 〈home〉 needs to be changed to 『room』 to accurately convey the information from the original text.

error_sentence: At 14:00 he will play basketball.
correct_sentence: At 14:00, he will play basketball.
correction: ,
error_type: Punctuation Error
error_severity: 2
error_description: ① Punctuation Error: According to English grammar rules and writing conventions, a comma is usually needed to separate a time adverbial from the main clause to clearly divide the sentence structure. In the original sentence, there is no comma separating the time adverbial 〈At 14:00〉 from the main clause 〈he will play basketball〉, which is a punctuation error. Therefore, a comma 『,』 needs to be added after 〈At 14:00〉 to make the sentence conform to English writing conventions.

error_sentence: It's so p
correct_sentence: At 18:00, he will have a bath.
error: It's so p
error_type: Sentence Redundancy Error
error_severity: 4
error_description: ① Sentence Redundancy Error: According to English expression logic, sentences should be complete in meaning and coherent with the context. The phrase 〈It's so p〉 in the original sentence is incomplete, cannot convey a clear meaning, and is unrelated to the context describing Tom's activities; this is sentence redundancy. Therefore, 〈It's so p〉 should be deleted to make the text expression more concise and reasonable.
