五、阅读理解
A 13-year-old boy has made a cheap machine that can help blind people read.
The blind can read by using Braille—a system of small bumps(凸起)that the blind touch to read the letters. The machine that makes these small bumps usually costs at least 2,000. It is called the Braille printer. The schoolboy, Shubham Banerjee, made a new Braille printer from a Lego tool that lets people create robots. Banerjee has called his new machine the Braigo—a combination of the words Braille and Lego. It costs just 350. It works by changing electronic text into Braille and then printing it using a computer or mobile machine.
Banerjee designed（设计）his Braigo for a school science exhibition. The big technology company Intel spent money on Banerjee’s machine last November, but they did not say how much money they put in. Banerjee also got 35,000 from his father to help him start the project. His father works as a computer engineer（工程师）at Intel. He spoke about why he gave so much money to his son, saying, “We as parents started to be interested more, thinking that he’s on to something and this invention has to continue.” Banerjee told the AP News, “My dream would probably be having most of the blind people... using my Braigo.”( )1.

How much will one save if he buys a Braigo instead of a usual Braille printer?A. Over 2,000.

答案
1.A 2.D 3.C
解析
【分析】
做这类阅读理解细节题，需先提取题干关键词，再回原文定位对应语句，对比选项得出答案。第1题关键词为Braille，定位原文第二段第一句即可找到答案；第2题关键词为价格，需对比普通盲文打印机和Braigo的售价计算差价；第3题关键词为设计原因，定位原文中关于设计目的的表述即可。
【解析】
1. 根据原文第二段第一句“The blind can read by using Braille—a system of small bumps that the blind touch to read the letters.”可知，Braille是帮助盲人触摸阅读的凸起系统，A选项符合描述；B、C、D均与原文内容不符，故选A。
2. 由原文第二段“The machine that makes these small bumps usually costs at least 2,000...It costs just 350.”可知，普通盲文打印机至少售价2000，Braigo售价350，差价为2000-350=1650，即至少节省1650，D选项符合；A、B、C均错误，故选D。
3. 根据原文第二段“Banerjee designed his Braigo for a school science exhibition.”可知，他设计该发明是为了学校科技展，C选项符合；A、B、D均与原文不符，故选C。
