第一个是黑板
第二个是钟

The giant black and tall,
Stands against the wall.
When white snakes wriggle on,
Their trails are shown to all.
一个黑大汉,
靠着墙壁站,
白蛇身上游,
脚印大家看.

Though I have neither legs nor feet,
I go all day and all night;
Although I cannot speak or laugh,
I can tell what others want to know.
没有腿,没有脚,
一天到晚不停跑；
报告信息供参考.
