3.Seeing with SoundAccording to a British news report,some blind people may finally get a chance to"see".(71)C Dr.Peter Meijer,a scientist at Philips Research Laboratories in the Netherlands,has developed a new system called the vOICe.The three middle letters in vOICe stand for"Oh,I see."Meijer's groundbreaking technology may change the lives of visually impaired (视力障碍) people all over the world.
A wearable setup of vOICe system consists of a head-mounted camera,stereo headphones and a notebook PC.The system translates visual images from a camera into complex sounds.(72)B
The program is based on the theory that people can hear certain sounds and learn to translate them into meaningful mental images.Everything has its own unique sound.(73)A The height of an object or person could be determined by pitch(音调).And a built-in colour identifier speaks out colour names when it is turned on.What the vOICe users had to learn is which sound went with which object.Meijer says that he is counting on the brain's ability to adapt.
(74)F Within two weeks,most people who experiment with the vOICe system are able to identify objects such as walls and doors.They are also able to identify certain situations,including whether the lights in a room are on or off.(75)G Meijer thinks that translating will eventually become automatic for many users of the vOICe,bringing a form of vision to them for the very first time.
A.Brighter areas sound louder than darker areas.
B.It then sends these sounds to a person through headphones.
C.However,they are not learning to see with their eyes; they are learning to see with their ears.
D.The vOICe system is aiming to treat blindness by translating images from a camera into audio signals.
E.Meijer supposes that the brain is interested in the information"content",but not the information"carrier".
F.To evaluate the new system's effectiveness,a number of visually impaired people were chosen to test the vOICe.
G.Over time,some users have even learned to"watch"television or"recognize"the outlines of buildings as they walk.
分析 本文属于说明文阅读,作者通过这篇文章主要向我们介绍了vOICe这种能让盲人"看"的技术系统,这种技术的发明为盲人带来了极大的便利.
解答 71.C.推理判断题.根据前一句"some blind people may finally get a chance to‘see'"可知,接下来要介绍如何"看".故选C.
72.B.推理判断题.根据前一句"The system translates visual images from a camera into complex sounds"可知,接下来要介绍声音是如何传到人的耳朵里去的.故选B.
73.A.推理判断题.根据前一句"Everything has its own unique sound"可知,不同的区域是如何转化成声音的.故选A.
74.F.推理判断题.根据后一句"Within two weeks,most people who experiment with…"中的"experiment"可知,前一句总体介绍测试这个系统的原因及参与测试的对象.故选F.
75.G.推理判断题.根据后一句"Meijer thinks that translating will eventually…"中的"eventually"可知,这句是总体介绍随着时间的推移使用者会取得怎样的进步.故选G.
点评 考察学生的细节理解和推理判断能力,做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确的选择.在做推理判断题不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.
