when i take pictures on auto mode,cant expose fast enough and pics are blurry

it would help if you could describe better the conditions in which you are shooting and what camera you have. The auto mode will try and guess what sort of picture you are after, autofocus can struggle in certain conditions such as low light or low contrast situations, the blurry pictures could be down to either the camera focusing on the wrong area of the frame or the shutter speed being too slow and resulting in motion blur. its hard to say without more information;
