听力原文：Many drivers do little more than look over the hood while driving. You must train

yourself to fix your eyes so that they can see not only the road ahead of you but objects on each side of you and behind you. Concentration is one of the most important elements in safe driving. The driver's seat is no place for window-shopping, nor it is a place for a tired driver or worried one. Driving an automobile is a full-time job.

A．They drive full time.

B．They do not concentrate on their window-shopping.
