EDITED ANSWER: I apologize. I read your question wrong. Hi, Sara! 年前 = years ago (must be preceded by a number) 去年 = last year Examples: 两年前我从高中毕业。= Two years ago, I graduate from high school (literally: Two years ago I from high school graduate). 十年前我和我妻子结了婚。 = Ten years ago, my wife and I got married (literally: Ten years ago I and my wife married). 去年我拿到了我的驾驶执照。 = Last year, I got my driver's license. 你去年才找到工作。 = You didn't find a job until last year (literally: You last year just found job).

年前，指的是过年之前的一段时间 before next year 去年，是指去年的一整年，都可以叫去年 last year 所以，去年包括年前的。 希望能帮到你

去年 just mean:the last year. 年前 a short peroid time before spring festival or new year.

Oh thanks a lot :)) now I understand completely

年前 is NOT a year. It is a time frame (period of time) that uses the start of a new year as its reference point, just like New Year's Eve is the day before New Year.
