error_type: Verb Tense Error
error_severity: 4
error_description: ① Punctuation Error: According to English writing conventions, the period 〈.〉 is unsuitable for separating the time adverbial 〈On Saturday〉 from the main clause, as they belong to the same thought group. Therefore, the period is changed to a comma 『,』 to maintain sentence structure coherence and reflect the logical relationship between the adverbial and the main clause; ② Verb Tense Error: Based on the context, the sentence describes planned future activities. When the subject is third-person singular, the present tense verb 〈does〉 does not meet the requirement for a future time adverbial; it should be changed to 『will do』 to form the simple future tense, accurately expressing an action that has not yet occurred.

error_sentence: Tom does his homework at 9:30, and he watches TV at 11o'clock.
correct_sentence: On Saturday, Tom will do his homework at 9:30 a.m., and he will watch TV at 11 o'clock.
correction: a.m.
error_type: Number Error
error_severity: 2
error_description: Number Error: According to English time writing conventions, the numerical time expression 〈9:30〉 requires a clear period indicator. Since the context does not provide other time references and daily activities often occur during the day, 『a.m.』 should be added to accurately indicate the morning period, avoid time ambiguity, and the complete form should be 『9:30 a.m.』.

error_sentence: Tom does his homework at 9:30, and he watches TV at 11o'clock.

error_severity: 1
error_description: Space Error: According to English writing conventions, a space must be kept when numbers and time units are used as separate words.

The past tense verb 〈cleaned〉 contradicts the future time reference; it should be changed to 『will clean』 to form the simple future tense, accurately expressing an action that has not yet occurred.

error_type: Nonfinite Verb Form Error
error_severity: 3
error_description: Nonfinite Verb Form Error: According to English grammar rules, the modal verb 〈will〉 requires the base form of the verb without 'to' following it.

error_sentence: On Sunday, he cleaned his room at 10o'clock, and plays basketball at 14o'clock. He has a bath at 18o'clock.
correct_sentence: On Sunday, he will clean his room at 10 o'clock, and play basketball at 2:00 p.m. He will have a bath at 6:00 p.m.
