大一大二大三大四英语怎么说

1.大一; the first year at college or university
(注意，freshman是指大一的“学生”）
2.大二; the second year of a course at college or university
(注意，sophomore是指大二的“学生”）
3.大三; the third year of a four-year course at college
(注意，junior是指大三的“学生”）
4.大四; the senior year at college
(注意，senior是指大四的“学生”）

freshman
sophermore
junior
senior

老外聊天的时候很随便的，一般都是year1 year2 year3 etc，
for example, when I was on year1, I did this subject.
senior 和 junior说的是 high school吧，

美国用freshman, sophermore, junior, senior
也可以是1st year, 2nd year, 3rd year, 4th year undergraduate

那个big来 big去的谁啊？去死吧。。
