One possible version:
Dear Sir,
I'm a student of Senior 3.I am writing to tell you about the discussion we've had about
whether to board in the school or rent a room which is outside the school.
At the beginning of this term,my parents and teachers asked me to beard in the school.
They say it will be very convenient for me to ask questions.Besides,they think boarding
will make it possible to make full use of my night time,and that I can also develop the ability
to look after myself.However,I have my own thought.Staying at the room which is outside
the school in the evening,I will have more time to work at my lessons.At the same time,I
can learn what I think I' m not good at.I really don't know what to do.Please give me
your advice!
Sincerely yours,
Li Hua
