5.It's often said that the eye is the window to the soul.But in this case,the eye is the window to Windows.At least,that was the goal when EyeTech Digital Systems got the help of some BYU engineering students in creating an all-in-one eye-tracking system.The idea behind the project was to create an inexpensive computer system that could be controlled completely with a person's eyes.The hope was that this system could be used by people with disabilities in parts of the world where they can't afford expensive eye-tracking systems.The students created the tablet(书写板)for their yearlong engineering project for their customer,EyeTech Digital Systems,an Arizona-based company that designs and develops eye-tracking software.
A separate BYU engineering team also worked with EyeTech last year to develop and improve the initial eye-tracking tephnology,but this year's focus was to put the eye tracking into a housing similar to a thick PC.The finished product runs Windows 7 and has the eye-tracking system built in.After a quick adjustment,the system can move the mouse to wherever the user is currently looking.All it takes is a blink(眨眼)to click.
Systems with similar abilities can cost upwards of 14,000.Butthestudentswereabletofindcheaper,readilyavailableparts,pushingthecostdowntounder1,500.Jedediah Nieveen,the captain for this year's team,said the project was a challenge,but one that was rewarding on many levels."A lot of times in school you just work problems out of books,"he said."But this allowed us to take what we learned and apply it to something in real life,something that can help a lot of people,and that's really helped me."
Although the primary purpose of the product is to help people with disabilities,the technology could also have broader applications in the fields of research,advertising and even gaming.

72.How long will the research of the eye-tracking project last in all?A
A.About two years.
B.Just one year.
C.Over three years.
D.Less than one year.
73.The eye-tracking system was created toC
A.help the poor students
B.improve the computer system
C.support the disabled people
D.help to cure people's disabilities
74.What did the BYU engineering students value most during the project?B
A.Earning money for their education.
B.Putting their theory into practice.
C.Showing their talents in technology.
D.Increasing their job opportunities.
75.What can be inferred about the future of the eye-tracking system?A
A.It may face a promising market.
B.It is welcome only to the disabled people.
C.It'll change the disabled people's social position.
D.It can improve the disabled people's main way of life.
分析 本文是一篇科教类阅读,文章主要介绍了眼球追踪器--用眼睛操作电脑的一种软件.该眼球追踪器主要是为了帮助残疾人而研制的,将来会达到既便宜而又质量高,因此还会适用于其它领域.
解答 BACBA
71.B细节理解题.根据第二段和第三段的内容可知,这种"eye-tracking system(眼球追踪器)"是用眼睛操作电脑的一种软件.故选B.
72.A细节理解题.根据第三段A separate BYU engineering team also worked with EyeTech last year to develop and improve the initial eye-tracking tephnology,but this year's focus was to put the eye tracking into a housing similar to a thick PC.可知这项工程去年已经进行了一方面,而今年还要侧重另一方面的研究,大体上需要两年的时间.故选A.
73.C细节理解题.根据第二段The hope was that this system could be used by people with disabilities in parts of the world where they can't afford expensive eye-tracking systems.和最后一段Although the primary purpose of the product is to help people with disabilities.可知该眼球追踪器主要是为了帮助残疾人而研制的.故选C.
74.B推理判断题.根据倒数第二段A lot of times in school you just work problems out of books,"he said."But this allowed us to take what we learned and apply it to something in real life,可知对这些学生来说,能够把所学知识用于实践对他们来说本身就是一个大大的奖赏.故选B.
75.A推理判断题.根据倒数第一段和倒数第三段的内容可知,该眼球追踪器将来会达到既便宜而又质量高,不仅适用于残疾人群,而且还适用于其它领域.因此,其前景将是很好的.故选A.
