Do you forget to turn off file lights and heaters when you go out of a room? In 2040 it will not mater. 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 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 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.

第1题:D
第2题:D
第3题:A
第4题:D
第5题:B
第1题:
主旨大意题。题干意思是“作者想要告诉我们……”。根据文章开篇第二、三句In 2040 it will not mater. They will turn themselves off—and on again when you return.(到了2040年,这就不重要了。它们会自动关闭,当你回来的时候再打开)可知,作者想要告诉我们到了2040年,电灯和热水器会自动打开和关闭,因此D项“2040年,电灯和加热器将会自动开关”正确。A项“2040年,我们将生活在没有灯和暖气的情况下”,B项“到2040年,我们将使用更多的灯和加热器”和C项“2040年将不再有电灯和暖气的开关”,都不对,故该题选D。
第2题:
细节事实题。题干意思是“下列哪一项是错误的?”。根据第二段第一句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.(传感器将通过中央家庭计算机工作,它们将做更多的事情,而不仅仅是为你打开和关闭火和灯)可知,传感器是多功能的,而且如果没有计算机,传感器做不了多少事情;由此可知A项“传感器是多功能的”和B项“没有计算机,传感器不能做很多事情”正确;C项“传感器将探测到火灾并发出紧急呼叫”,根据第二段第三句They will detect fire and if you are out of the house, the computer will call the fire brigade.(它们会探测到火灾,如果你不在家,电脑就会呼叫消防队)可知,C项也正确;D项“如果你乱动门锁或窗户,你会被认为是入侵者”,第四段提到It will be impossible to lose the key, and a housebreaker will have to tamper with the lock or with a window. It is not very difficult to make such tampering send a signal to the computer.(钥匙是不可能丢的,而破门而入的人就得在锁上或窗户上乱动。要使这种篡改行为向计算机发送信号并不困难),这里只是说如果有闯入者,那么他需要破解门窗锁的密码,这种破解会很轻易地被电脑感知到;而不是说如果你要改变门窗锁你就会被当作闯入者。所以D项不对。故该题选D。
第3题:
细节事实题。题干意思是“根据作者,到2040年新科技会……”。A项“将把我们从现在的使用钥匙中解放出来”,第二段最后一句You will open them using your personal card—the one you use for shopping—maybe using a number known only to you.(您将使用您的个人卡——购物时使用的那张——打开它们,可能使用的号码只有您自己知道)可知,到2040年人们将不再使用钥匙来开锁,所以A项正确;B项“将一切都变成传感器”,文中没有提到,且该项太绝对;C项“会使门锁过时”,文中只是说不需要锁了,没有说门锁过时,所以项也不选;D项“将消除所有犯罪”,新科技可以更好的增强防御系统,但是不能消除所有犯罪,太绝对,该项错误。故该题选A。
第4题:
细节事实题。题干意思是“由于有计算机,到2040年人们将……”。最后一段讲到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.(计算机将不仅仅是一个消防员和警察的仆人。它将是一个娱乐,你的大部分娱乐将直接进入你的家。当然,现在是这样,但到2040年,“娱乐”的意义将大得多),由此可知电脑可以在家里提供给人们更多的娱乐;而没说人们不能出门娱乐,或不需要电视,或者被电脑控制,因此A项“在外面没有娱乐”,B项“将用电脑取代电视”和C项“将被计算机控制”均错误;只有D项“在家里会有更多的乐趣”符合题意。故该题选D。
第5题:
主旨大意题。题干意思是“这篇文章最好的题目是……”。全文讲的是2040年科技发展给人们家居生活带来的便利。A项“传感器和计算机”,题目太大,过于总结文章内容;B项“2040年的家庭生活”很好的概括了文章的内容,符合题意;C项“科学技术的发展”偏离了文章主旨;D项“2040年的灯和加热器”过于狭窄,不能表达技术的创新对生活品质的提升。故该题选B。
