Question

阅读理解 　　Life is never easy for the disabled．To improve understanding and raise support for people with disabilities, the United Nations made December 3 the International Day of Disabled Persons in 1992． 　　One way that life for the disabled can be improved is through new technology． 　　A recent development is an“electronic eye”that can be fitted to a pair of glasses to help the blind cross roads more safely．Last Monday, Japanese researches said the new device(装置)uses a camera and computer to sense the location of a crossing point, its width and the color of traffic lights．The camera would be at eye level, and be connected to a tiny computer．It would relay information using a voice speech system．It would give commands and information through a small speaker placed near the ear．The scientists are now working on the best way to put the device into a pair of glasses that a blind person can wear． 　　In another development, new technology is opening up the world of computers for the disabled．Thanks to a hands-free device invented in Canada, using a computer will soon be a lot easier for disabled people．The“Nouse”, short for“nose as mouse”, uses movements at the tip pf the user's nose to direct the cursor(光标)on the screen．Once the computer is turned on, an ordinary Web cam(computer camera)takes a close up photo of the tip of nose．It then mirrors the nose's movements on screen to move the cursor, just as a hand would normally move a mouse． 　　“The Nouse is also programmed to let users give orders by blinking(眨眼)．”For example, the right mouse click would require the user to blind twice and the left mouse click would require the user to blink three times, explained a researcher． 　　“Devices such as the Nouse are wonderful because they give disabled people greater independence,”said Penn-Symons, chief executive(首席执行官)of British charity(慈善团体)Disabled Living Foundation． (1) Through an“electronic eye”, a blind man could ________ how far to go forward． [　　] A． see B． hear C． feel D． guess (2) If a disabled person wants to make two right mouse clicks and three left mouse clicks, how many times should he blink, according to the example of using the Nouse in the fifth paragraph? [　　] A． Five times． B． Ten times． C． Fifteen times． D． Thirteen times． (3) How many main ways to help the disabled person does this passage refer to? [　　] A． One． B． Two． C． Three． D． Four．

Answer 1

答案：1．B;2．D;3．B;
解析：

可以用逻辑运算法来解。由第五段可知，残疾人需眨眼的次数是2×2＋3×3＝13次。

提示：

(1)	由原文第三段中“It would relay information using a voice speech system．It would give commands and information through a small speakers placed near the ear．”可以推出答案。
(3)	可用概括归纳法来解。认真阅读分析文章可知，本文主要介绍如何用electronic eye和the Nouse两种高科技手段来帮助残疾人提高生活质量，尽管也提到了设立“国际残疾人日”，但与题干的main ways不符。
