3.Seeing with Sound
According 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 (視力障礙) 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(音調(diào)).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 本文屬于說明文閱讀,作者通過這篇文章主要向我們介紹了vOICe這種能讓盲人"看"的技術(shù)系統(tǒng),這種技術(shù)的發(fā)明為盲人帶來了極大的便利.
解答 71.C.推理判斷題.根據(jù)前一句"some blind people may finally get a chance to‘see'"可知,接下來要介紹如何"看".故選C.
72.B.推理判斷題.根據(jù)前一句"The system translates visual images from a camera into complex sounds"可知,接下來要介紹聲音是如何傳到人的耳朵里去的.故選B.
73.A.推理判斷題.根據(jù)前一句"Everything has its own unique sound"可知,不同的區(qū)域是如何轉(zhuǎn)化成聲音的.故選A.
74.F.推理判斷題.根據(jù)后一句"Within two weeks,most people who experiment with…"中的"experiment"可知,前一句總體介紹測試這個系統(tǒng)的原因及參與測試的對象.故選F.
75.G.推理判斷題.根據(jù)后一句"Meijer thinks that translating will eventually…"中的"eventually"可知,這句是總體介紹隨著時間的推移使用者會取得怎樣的進步.故選G.
點評 考察學生的細節(jié)理解和推理判斷能力,做細節(jié)理解題時一定要找到文章中的原句,和題干進行比較,再做出正確的選擇.在做推理判斷題不要以個人的主觀想象代替文章的事實,要根據(jù)文章事實進行合乎邏輯的推理判斷.
