“我已经上大学一年了”这句话用英语怎么说？？？？？？？？？

i have been studied in university for one year.

Now I'm going to be a sophomore.

I have a year to college

i have been studying in college for one year.
楼上的有错误
been 是系动词 怎么能加动词的完成时态？？
所以是studying表示完成进行时 意思是此事一直在发生 对于现在的影响还在继续

I'm a freshman.

i'm a freshman in college
i've been studying in college for 1 year
