他曾经是一个学生用ONCE怎么说

once he was a student
i will pick you up once you got to Beijing

1:Once he was a student;

2：I will pick you up as long as you come to Beijing.

Once he was a student .
I will meet you as soon as you get to Beijing.

once he was a student．

i will pick you up as long as you come to bj．

As long as you come to Beijing, I'll pick you up

绝对标准的翻译！！！！上面几位把只要都翻译错了！！！
望采纳！！！

这儿的once就不是曾经的意思了，应是“一旦”的意思。所以翻译为“
Once you come to Beijing, I will go to pick you up”。 OK
