Like, is there a thing beyond the counting the rings?

比如，除了数环之外还有什么事情吗？

Each ring took one year to grow, so that by counting the rings we can tell how old the tree is.

每一个年轮都要花一年时间长出来, 所以只要数一数年轮, 就能知道这棵树有多少岁了。

Cutting it half through and counting the annual rings with the aid of a lens, we find its age to be no less than 255 years.

将它切开一半，借助透镜数年轮，我们发现它的年龄不低于255年。

Cutting it half through and counting the annual rings with the aid of a lens, I found its age to be no less than 255 years.

把它切开一半，用镜头数年轮，我发现它的年龄不低于255年。

All right, now I'm picturing Gandalf, like, serving drinks to these three tree  ring scientists sitting there looking at the bar, counting the rings on the bar.

好吧，现在我正在想象甘道夫，为这三位年轮科学家提供饮料，他们坐在那儿看着吧台，数着吧台上的年轮。
