Do you forget to turn off the lights and heaters when you go out of a room? In 2040 it will not matter. They will turn themselves off—and on again when you return. You will choose the temperature for each room, the lighting and the humidity. A sensor will detect the presence of a human (and, with luck, ignore the dog!) and turn the systems on, and when the humans leave it will turn them off again.
The sensors will work through the central home computer, and they will do much more than just turn the fires and lights on and off for you. They will detect faulty electrical appliances, plugs or switches, isolate them so that they cannot 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 fire brigade. It will also call the police should the sensors detect an intruder. This will not be too difficult because the locks on the outside doors will be electronic. You will open them using your personal card—the one you use for shopping—maybe using a number known only to you.
It will be impossible to lose the key, and a housebreaker will have to tamper (拨弄) with the lock or with a window. It is not very difficult to make such tampering send a signal 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. For one thing, you will be able to take part actively, rather than just watching...
The author intends to tell us that______.
选项
A、in 2040 we will live without the lights and heaters
B、in 2040 we will use much more lights and heaters
C、in 2040 lights and heaters will be on and off automatically
D、in 2040 there will be no switches of lights and heaters
答案
C
解析
本题问作者试图告诉我们什么。第一段指出,出门时你会不会忘记关电灯和电热器?到2040年,你忘记了也没关系,因为它们会自动关闭——你回到家后它们还可以自动开启。不仅如此,你还可以为不同房间设置不同温度、亮度、湿度,因为传感器可以感测到人进入房间(可幸的是,它对狗则不予理睬),并自动开启系统,人离开时再关闭。因此,本题的正确答案应是C“到2040年,电灯和电热器会自动开闭”。
