麻烦帮忙看看这段英文有没有什么问题
Next week,we will begin to learn Japanese.We will have eight classes every day,except Saturday and Sunday.I have to learn Light Weight Enterprise Development in the evening.As a senior student,I feel time flies.I have a lot of things to learn:Spoken English,Data Structures and Algorithms,Operating System,Computer Network,Discrete Mathematics and so on.I have a lot of things to do,but I know I should do them one by one.I know health is important,so I play basketball almost every day.I believe I can,impossible is nothing.

答案

Discrete Mathematics and so on,and的前加个逗号.我认为其他的都对.
impossible is nothing,可以是可以,但因为是中国式翻译的英文,所以老外可能觉得别扭.
加油!
