Once there was no zero.
Once there was no zero(零).To write the number sixty-three,people wrote 63.To write six hundred and three,people wrote 6 3.The space was there to mean “not any” tens.Sometimes people did not remember the space.It was hard to see and to read.
Later people used a dot(点) to hold the space.Six hundred and three looked like this 6·3.But the dot was hard to see.So people put a circle around it like this 6⊙3.Then people could see the dot.They remembered the space.
At last,only the circle around the dot was used.It was like a zero.This is one story of how the zero came to be used.
Now zero has many important uses.Zero tells how many.Can you tell some other ways zero is used?翻译

起初是没有零的.如果要表示数字六十三,人们都写成63,要写六百零三时又会写成6 3.中间的空白表示“什么都没有”.但是有时候人们不记得这段空白,因为太难辨认了.
后来人们用一点来填充这段空白,于是六百零三就写成了6·3.但是这个一点也不容易被看到,于是人们就在这一点外画了个圈,变成6⊙3以便分辨.
最后,只有这个绕在一点外的圆圈被保留下来了,这圆圈看起来很象我们现在用的“零”.这就是关于数字“零”的典故.
现在零有许多重要的用途.零能帮助我们计数,你还能说一下数字“零”还有什么其他的用途吗?
