通过连接两个计数器，可以获得1到19的连续计数。

By hooking together two counters, you can obtain a sequential count from 1 to 19.

但是这个结构一旦第一个计数器达到10，就开始重新计数，不能提供1到20的连续计数。

But the problem with this configuration is that it does not provide sequential count from 1 to 20 because the first counter begins to count over again once it has reached 10.
