Dear Maria，
How are you？My life has changed a lot since I became a student of Grade 9. I used to have less homework and I could learn my lessons well. However,everything is different now. I have more homework to do every day. I'm under great pressure. I used to take part in different activities after school，but now I have to study harder and sometimes even stay up late. What's more， I used to spend the weekends with my family and friends. Now I have less time to spend with them because of my study.
Though I feel tired，I will keep going until I enter my dream school. Do you feel the same？
Yours，
Liu Mei
