These send signals through the spinal cord (脊髓)to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these
19、weak electrical signals from reaching the muscles，” Tavella says. “Our system allows disabled people to communicate with external world and also to control devices.”The researchers designed a special cap for the user. This head cover picks up the signals from the scalp(头皮) and sends them to a comput

They help the computer react to commands from the brain.Prof. Millan, the team leader, says scientists keep improving the computer software that inter

25、the text?ASwitzerland, the BCI Research CenterBNew Findings About How the Human Brain WorksCBCI Could Mean More Freedom for the DisabledDRobotic Vehicles Could Help to Cure Brain Injuries答案课时作业(八).本文是“我”外出购物时的一次尴尬的经历。1B为了消磨时间，“我”买了报纸和巧克力，故选bought。2A由文章推断出，“我”走进了一家咖啡店，故应选went。3Ato sit at作tables的后置定语，
26、意为“可以在旁边就座的桌子” 。4C按常理“我”应把报纸等放在桌子上，而不是“推到”或“拉到”桌子上，故应选 put。5C由下文可知，回来时“我”发现他开始吃“我”的东西，说明他坐在旁边的座位上，故选 sitting。6B用it指代前文中未知的人。7D头发应是被染成艳红色的，故应选colored。8B面对这样一个人，“我”不想惹麻烦，trouble合乎文意，为正确选项。9C由下文可知，“我”吃的是这个男孩正吃的巧克力，这引起了对方的某一反应。比较四个选项，再根据上下文，用名词surprise比较合乎当时的情形。10B“a 序数词名词”常用来表示“再一个，又一个”，与下文took a third
27、 piece相呼应。11A根据文意可知那个男孩起身要走，故选择stood。12B男孩生气了，必定说了发泄的话，比较四个选项，wrong为最佳选择。13B男孩骂了“我”，导致大家都朝“我”看，而“我”不想与他争吵，可见“我”的反应与上文描述的气氛恰恰相反，故选择but构成转折关系。14C固定搭配make a mistake意为“犯了个错误”。15B“我” 在喝完咖啡准备离开时发现了自己的过错，故应选leave。.A本篇文章讲的是在Dixie Heights High School里面开了一家咖啡店，该店是由那些有特殊学习需要的学生来经营的一个实验试点。16B主旨大意题。由全文内容尤其是第七段可知
28、答案。17C推理判断题。根据文章的第五段Although some of the students are not disabled, many are, and the PIT helps them prepare for life after high school.和第六段They learn not only how to run a coffee shop but also how to deal with their affairs. They keep a timecard and receive paychecks, which they keep in check regis
29、ters.可以知道这家咖啡店的开展主要是为了培养学生的实践能力。18C细节判断题。根据after hanging up with the teacher可知答案。hang up 是“挂断电话”的意思。19B推理判断题。根据文章第九段Kenton County Food Service Director Ginger Gray helped. She made sure all the drinks, which use nonfat milk可知应选B项。20D细节理解题。文章多处告诉我们这是一家咖啡店，倒数第四段的Should schools be selling coffee? What
30、about sugar content？得知，这两种被预订的很可能是咖啡。 故A的说法是正确的。由文章第一段知B项是正确的。 由第五段Although some of the students are not disabled, many are, and the PIT helps them prepare for life after high school.可知C项正确，即此店的开办目的主要是为了帮助那些有特殊学习需求的残疾学生，而不是为了老师。故选D。B这是一篇科普类文章。作者向我们报道了关于人脑信息和电脑信息研究的最新突破，该技术目前正准备在病人身上应用。21B 考查细节理解。由第一
31、段可以看出，BCI技术是科学家一直研究的to link the brain with computers技术，由此可知B项正确。C项有极大的干扰性。22D 考查细节理解。由第三段的In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand.可知是说通过他的思维。故选D。23C考查事实排序。由该段可知，信号从the scalp(头皮)发出后被a special cap接收，接着传到了a computer，然后到轮椅，由此可知C项正确。24B 考查细节理解。最后一段One is testing with real patients, so as to prove that this is a technology they can benefit from.中的they指的是patients，证明他们能从中获益，也就是对于他们是有用的(useful)，因此可知答案。25C考查主旨归纳。 文章向我们介绍了瑞士BCI研究中心的一个新技术的工作原理，以及给残疾人带来的实惠。
