DResearchers recently have tapped the brainwaves of a paralyzed(man unable tospeak and turned what he intended to say into sentences in a medical first.The device,created by a team at the University of California,San Francisco,analyzesbrain waves to decode )what a person is trying to say and then displays the text on acomputer screen.It will take years of additional research but the study results mark animportant step toward one day restoring more natural communication for people who can'tspeak because of injury or illness.Volunteering to test the device was a man in his late 30s who 15 years ago suffered abrain-stem stroke that caused widespread paralysis and robbed him of speech.Theresearchers placed electrodes()on the surface of the man's brain,over the area thatcontrols speech.A computer analyzed the patterns when he attempted to say commonwords such as“water'”or“good”,eventually becoming able to differentiate between50words that could generate more than 1,000 sentences.Started with such questions as "Howare you today?”or“Are you thirsty?”the device eventually enabled the man to answer“Iam very good."or"No,I am not thirsty."-not voicing the words but translating theminto text.It takes about three to four seconds for the word to appear on the screen.That'snot nearly as fast as speaking but quicker than tapping out a response.Harvard neurologists Leigh Hochberg and Sydney Cash called the work a "pioneeringdemonstration".They suggested improvements but said if the technology pans'out iteventually could help people with injuries,strokes or illnesses like Lou Gehrig's diseasewhose "brains prepare messages for delivery but those messages are trapped".32.What can we learn about the device?A.It can treat brain diseases.B.It can turn one's mind into texts.C.It can turn spoken words into texts.D.It can translate all kinds of languages.33.What is the third paragraph mainly about?A.The process of testing the device.B.The problems of using the device.C.The instructions of making the device.D.The subjects involved in the device test.34.What is Leigh Hochberg's attitude to the device?A.Positive.B.Negative.C.Doubtful.D.Indifferent.35.What is the best title for the text?A.A Device That Treats the ParalyzedB.Scientists Create a Mind-Reading DeviceC.Scientists Study Brain Waves of the ParalyzedD.A Device That Helps Common People Communicate神州智达英语·调研卷Ⅱ第6页（共10页）扫描全能王创建
