Question

英语阅读题 T/F 30分
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?
（）AT first ,zero was not used by people
( )the space between 6 and 3 was easy to see and to read
()later,when people wrote eight eight hundred and nine,they would put a circle with a dot in it between 8 and 9
()zero came from the ciecle around the dot
()zero isn't useful in our life
()the space between 6 and 3 means "not any " tens
()people put a ciecle around the dot so that they could see it
