问题     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... [br] Which of the following statements is NOT true?
选项 A、You can be taken for an intruder if you tamper with the lock or with a window.
B、The sensor will detect fire and make an emergency call.
C、Without a computer, the sensor can not do much.
D、The sensor is multi-functional.
答案 B
解析 本题是一道判断是非题。问下面哪个是不正确的。针对四个选项，利用查阅式阅读法，结合原文相关内容，我们发现文章第二段第三句指出，如果你不在家时传感器感测到火灾，计算机就会告知消防队。传感器仅仅是一个感应装置，它感应到异常现象后将信号传给负责总控制的计算机，由计算机对信号处理后再发出相关信息。因此，本题的正确答案应是B“传感器感测到失火就发出紧急呼叫”，这种说法是不对的。
