【答案】Dear Smith
How's everything going？I've been in a dilemma these days.Now I am at the stage of choosing three courses out of seven in high school.This leaves me hesitated about two courses，I hope you can offer me some advice.
From my point of view，the main purpose of the curricula-variable system is for scientific talents and to maintain education fair to the maximum extent.As far as I am concerned，physics from which we can learn nature of some phenomena lays solid foundation for new inventions，and helps us explore the future.History is a subject for us to have a good understanding of the past and learn something meaningful from the past.
Both of the subjects are attractive.So I would be grateful if you could share some of your thoughts with me.
Yours sincerely，
