error_severity: 3
error_description: Word Redundancy Error: According to the original meaning, this describes 'Tina gets up'. The simple present tense is commonly used in English to express daily habits. Here, 〈is get up〉 contains word redundancy because 'get up' itself means to get out of bed. It is necessary to delete 〈is〉 from 〈is get〉 and change it to the third-person singular simple present tense form 『gets』 to represent Tina's regular action of getting up.

Then』 to form a new independent clause in compliance with English syntax rules; ② Case Error: According to English writing conventions, the first letter of a word at the beginning of a sentence needs to be capitalized, meaning 〈, then〉 should be changed to 『. Then』.
