Children study on holidays
These days, students study on holidays because of school exams. Do you think it is right or not? I think not. Holiday is the day to enjoy yourself with your family. We have to show off our energy on holidays. If we only study on holidays, we have to study till we die. I will recommend that you study and play as well.
Someone who only studies on holidays
I am again studying. Although it is Christmas, I am studying for 3 hours. I am so tired of "Studying on a holiday." However, I want to have good scores in my big exams. I have to study hard.
The next day.
"Nickeal!! Wake up!" Someone was calling me. "What?" I woke up. It was school and I was sleeping. I glanced at my teacher. She looked really angry. I didn't understand what was going on. I had a class with my teacher and then, I woke up in the class. Did I really sleep like everyone says so? This was all studying's fault if I didn't study that hard, I might not be asleep. I can't study harder like that again.

Explanation: Use on for the word holiday. Use for for time duration. Be consistent of your verb. Also, when you use did, the main verb must be in present tense. Study the rest of the correct sentences, how they're formed to make good ones.
