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(書寫板)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.

分析 本文是一篇科教類閱讀,文章主要介紹了眼球追蹤器--用眼睛操作電腦的一種軟件.該眼球追蹤器主要是為了幫助殘疾人而研制的,將來會達到既便宜而又質(zhì)量高,因此還會適用于其它領(lǐng)域.
解答 BACBA
71.B細節(jié)理解題.根據(jù)第二段和第三段的內(nèi)容可知,這種"eye-tracking system(眼球追蹤器)"是用眼睛操作電腦的一種軟件.故選B.
72.A細節(jié)理解題.根據(jù)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.可知這項工程去年已經(jīng)進行了一方面,而今年還要側(cè)重另一方面的研究,大體上需要兩年的時間.故選A.
73.C細節(jié)理解題.根據(jù)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.可知該眼球追蹤器主要是為了幫助殘疾人而研制的.故選C.
74.B推理判斷題.根據(jù)倒數(shù)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,可知對這些學生來說,能夠把所學知識用于實踐對他們來說本身就是一個大大的獎賞.故選B.
75.A推理判斷題.根據(jù)倒數(shù)第一段和倒數(shù)第三段的內(nèi)容可知,該眼球追蹤器將來會達到既便宜而又質(zhì)量高,不僅適用于殘疾人群,而且還適用于其它領(lǐng)域.因此,其前景將是很好的.故選A.
點評 本文考察學生的理解推斷能力以及細心程度,只要抓住文章的關(guān)鍵詞,采用尋讀的方法查找細節(jié),就能找到正確答案.
