If you ask people today why they use telel-phone to communicate with their friends or whythey turn to television for entertainment(娱乐),they would look at you as if you were crazy.Wedon't think about a telephone or a television or acar as being strange things.These things havebecome such an integral(不可缺少的)part of lifethat they are no longer noticed,let alone(更不用说)remarked upon.
