“几年前” 用英语有哪些说法？

a few years ago
= several years ago
= years before （=many years ago）
= years ago (但通常放在句尾作为时间副词)

several years ago;

A,Few,years,ago几年前。

嘿嘿，有意思：

A few years ago=
‘ ’before
‘ ’back
Years ago
Several years ago
Several years back
Some years ago
Some years back
Couple years ago
Couple years back
Couple years （back） then (微口语化，有误，忌用)

in the past years

a couple years ago
