Dear Sigmund Friend
     I am a Grade 9 student. I have  1 problem, and I do not know how to deal  2  it.
    I have a lot of homework every day, and I have no choice  3  to do it. I often stay up late to complete  4 ,
and then feel tired the next day.
     Sometimes, I want to  5 to do so much work, but usually I just accept it. I understand that it is important
to do my homework and  6  on time. However, I hardly have any spare time for my hobbies  7 playing
volleyball and ping-pong. I really feel bad about that. I often doubt whether it is worth  8 so hard.
    I am  9 a holiday without homework so that I can relax and have some time for my hobbies. What should I
do? Can you offer me some suggestions? They will be of great value to me. I hope to  10 you soon.
                                                                                                                                   Best wishes
