大家好！我是团团。现在，人类几乎每天晚上都会烧火。
Hello, I am Tonton. Now, humans make the fire almost every night.
我几乎每天晚上都要烤火。所以，我过上了比以前更加温暖幸福的生活。
And I also warm myself by the fire almost every night. So, I live a warmer and happier life than before.
但是，我有点不高兴。因为人们不喜欢靠近我了。
But I feel a little upset, because human don't like to come near me anymore.
总是在我身边玩耍的小孩已经长大了。
The children who used to play around me have grown up.
没有人在我的身上休息，没有人在我身上敲打野果。
No one rests on me, and no one knocks wild fruit on me.
没有人在我身上打制石头工具，也没有人在我身上晾晒动物的皮毛了。
No one makes stone tools on me, and no one dries fur on me.
我很难过，我想做一块有用的石头。
I am so sad. I want to become a useful stone.
圆圆说：“团团，别难过。我们帮助人们围着火堆。”
Then Yuan Yuan says, " Tonton, don't be sad. We help people enclose the fire."
“我们挡住了飞溅的火星，不让人类受伤。”
"We protected humans from getting hurt by flying sparks."
“我们挡住了风，不让小小的火苗熄灭。”
"We protected the small flame from wind."
“我们挡住了灰烬，灰烬盖住了火星，火种就保存了下来。”
"We protected the spark from the ash, and the ash covers the spark, then the spark is preserved."
我们都是有用的石头。
So we are useful stones.
