Error analysis:
error_sentence: On Saturday I get up early.
correct_sentence: On Saturday I got up early.
error: get
correction: got
error_type: Verb Tense Error
error_severity: 2
error_description: Verb Tense Error: According to English grammar rules regarding the agreement between time adverbials and verb tenses, the time adverbial 〈On Saturday〉 clearly indicates past time, thus the verb should be in the simple past tense. The present tense verb 〈get〉 in the original sentence conflicts with the past time adverbial, so it is corrected to the past tense form 『got』, forming the correct structure 『On Saturday, he got...』 to ensure tense consistency.

error_sentence: On Sunday I did my homewotk.
correct_sentence: On Sunday, I did my homework.
correction: ,
error_type: Punctuation Error
error_severity: 2
error_description: Punctuation Error: According to English writing conventions for punctuation with introductory time adverbials, when a complete time adverbial like 〈On Sunday〉 appears at the beginning of a sentence, a comma must be added after it to separate it from the main clause. Therefore, it is corrected to 『On Sunday, I did my homework』 to comply with writing standards.

error_sentence: On Sunday I did my homewotk.
correct_sentence: On Sunday, I did my homework.
error: homewotk
correction: homework
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: Spelling error correction: According to standard English spelling rules, 〈homewotk〉 contains a letter order error; the correct spelling should be 『homework』 (a compound word formed from “home” + “work”). Therefore, the misspelled 〈homewotk〉 is corrected to 『homework』 to ensure the word conforms to standards and is easily understood.

error_sentence: I cleant the room.
correct_sentence: I cleaned the room and watched TV.
error: cleant
correction: cleaned
error_type: Verb Tense Error
error_severity: 2
error_description: Verb Tense Error: According to English verb rules, 〈cleant〉 is a non-standard past tense form, and based on the past time adverbial hint in the sentence, the standard past tense form is required. Therefore, the non-standard past tense 〈cleant〉 is changed to the standard past tense 『cleaned』; this correction also meets the grammatical requirement for verb tense consistency with the time adverbial.

error_sentence: I cleant the room. And watch TV.
correct_sentence: I cleaned the room and watched TV.
error: . And watch
correction: and watched
error_type: Conjunction Error
error_severity: 3
error_description: ① Conjunction Error: According to English rules for parallel structures, a conjunction is needed to connect the two parallel actions 〈watch TV〉 and 〈cleant the room〉. The original sentence uses a period, causing a structural error. Therefore, the separate clauses are changed into a compound sentence connected by the coordinating conjunction 〈and〉 to comply with English compound sentence grammar; ② Verb Tense Error: According to the principle of tense consistency in context, the past time adverbial in the sentence indicates that the past tense should be used. Therefore, the present tense verb 〈watch〉 is changed to the past tense 『watched』 to maintain consistency with the tense of other verbs in the sentence.
