when和 how long ago 用于询问时间的区别

对于含有 ago 短语的句子，如果要对这个短语提问，是该用when，还是该用how long ago。如：

He joined the company five years ago.

如果对 five years ago 提问，应该用下面的哪一句？

When did he join the company?

How long ago did he join the company?

同意黎老师的解答，这里再补充一点意见：

对"He joined the company five years ago."这个句子的时间状语提问有三种。

1. 对five years ago提问：

When did he join the company?

2. 对five years提问：

How long ago did he join the company?

3. 对five提问：

How many years ago did he join the company?
