Why there are so many lines on the nurbs ball?

Today I created a nurbs primitive ball, it appears like this
Then I pressed 1 Key on the keyboard.then 3 key ,then 4key.then the ball becomed this.

I do not know why. I do not want to edit the ball with so many lines.How can reduce them?THank you!

It looks like you've toggled subdivision mode.
Try pressing 1 again. That should set it back to the original.

However since it's a NURBS ball you know you only edit the points (the purple dots in your last image), not the edges themselves, so it actually doesn't really matter how many edges it appears to have.

1,2 and 3 control the smoothness display for nurbs. (subdiv stuff is for polymeshes)
When you create the sphere, there are options for the resolution. Using the shelf icon uses default values.

Thank you for all your solution. I think I understand! I found when I pressing 1 2 3 ,the nurbs display atrributes in the atrributes editor are changing just now! Thank you very much!
