单选题 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...

单选题 The author intends to tell us that ______.

【正确答案】 C

【答案解析】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”。

单选题 Which of the following statements is NOT true?

【正确答案】 B

【答案解析】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。

单选题 According to the author, in 2040, new technology ______.

单选题 Thanks to computers, in 2040 people ______.

【正确答案】 D

【答案解析】本题是一道具体细节题。问到2040年人们将如何。文章第一段和第二段提到了许多未来生活的变化。最后一段又指出，计算机不仅仅能做好一个集消防队员、警察为一身的仆人，它还会给你带来很大乐趣，它将把乐趣带入你的家里。当然，这一点它目前已经做到了，不同的是，到2040年，“乐趣”的性质就大不相同了，例如：你将可以参与到乐趣活动中去，而不是像现在这样仅满足于观看……。因此，本题的正确答案应是D“计算机将使人们在家里获得更大的乐趣”。

单选题 The best title for the passage might be ______.

【正确答案】 A

【答案解析】本题问本文的最佳标题可能是什么。通读全文，我们知道文章第一段谈到了未来2040年的家居生活更舒适，第二、三两段谈到了未来计算机如何将使家居生活更安全，第四段谈到了计算机将给家居生活带来更大的乐趣。由此可见本文的主题应该是：2040年的家居生活。因此，本题的正确答案应是A。
