I like Physical education and that's probable my
favorite subject. Usually when the class come, I have
a strong desire to go outside and I think PE class is really good
enjoyment. I like to go out to exercises, and after exercising
I can study more better because I can concentrate easily
but I will feel better. My mind will be more
alert(灵活的).Some of my classmate don't want to have PE
classmate.
They think it is a waste of time and do lessons is what 
we want to do in PE class. It does great harm to both
their healthy and their study. I think PE class is a
good balance to purely mental science subjects.
