Create a separate layout. Remove the snippet for column left.
Tell pages/index to use the separate layout: document::$layout = 'newlayout';
Thanks very much and sorry for my late reply.
With your help,I have see the 1column for the frontpage and other pages with the 2column,and I have find one issue:it is work good for the PC but not good for the phone.With the default theme it is with the search bar and categories for the frontpage like the left and after the modify it is without the search bar and categories for the frontpage like the right,and other pages work well with that.
So what should I do next?

When 2.0 is released you can simply use Bootstrap syntax like hidden-xs or hidden-lg to toggle content for different devices.
I recommend getting ready to transition to 2.0 any day near.
OK.Thanks.I will wait the 2.0 for my next inflatable equipment website.
