我记得当一名志愿者。

I remember being a volunteer.

他想当一名志愿者去那里支教。

He wanted to work as a volunteer teacher in the village.

你是如何知道杨雷喜欢当一名志愿者的？

How do we know Yang Lei enjoyed her time as a volunteer?

试想一下，当一名志愿者一周的时间需要面对五个不同的人请求他/她解决同一类电脑或者其他什么故障，他/她一定会觉得无所适从。

When a volunteer helps you with your computers and something goeswrong, you don’t want to overwhelm him or her with five separate help requestsduring the week.
