When was it invented教案

　　the sensors will work through the central home computer, and they will do much more than just turn the fire and lights on and off for you. they will detect faulty electrical equipment, wires or switches, separate ( 隔離) them so that they can’t harm anyone, and then warn you that they need repair. they will detect fire and if you are out of the house, the computer will call the fireman. it will also call the police if the sensors detect a robber. this will not be too difficult because the locks on the outside doors will be electronic. you will open them using our personal card------ the one you use for shopping-----may be using a number known only to you.

　　it will be important to lose the key, and a housebreaker will have to tamper ( 亂動) with the lock or with a window. it is not very difficult to make such tampering send a signal ( 信號 ) to the computer.

　　the computer will be more than a fireman-policeman-servant. it will be an entertainer, and most of your entertainment will come right into your home. it does now, of course, but by 2040 entertainment will mean much more. you will be able to take part actively, rather than just watching.
