1. I wake up at seven o'clock. (correct)
2. We're open till 6 o'clock. (correct)
3. Can't you wait until we get home? (correct)
4. I finished my homework by ten o'clock.
5. I read books between 8 and 9.
6. We are going home from 2 to 3.
Explanation:
In sentence number 4, the error is misplaced modifier. It means that you placed the word separately from a word it modifies. In number 6, preposition to is not necessary anymore since you already use the verb going which indicates the act that you are heading home.
Hi, Sophia! Thank you for submitting your homework. There are just minimal corrections on it. See the explanation and we will discuss that in our class on Wednesday. Please don't forget also to put punctuation marks at the end of your sentences. Thank you, Sophia! Keep doing well. I'll see you tomorrow in our class.
