15．Many people believe that hunger is only a problem in the developing world．________，it is a problem all over the world．（　　）
A．As a resultB．On the contraryC．In additionD．For another

分析 很多人認(rèn)為饑餓僅僅是發(fā)展中國家的問題．相反，這是全世界的問題．

解答 答案是B．本題主要考查介詞短語辨析．a(chǎn)s a result因此；on the contrary相反； in addition此外； for another 再則；根據(jù)句意判斷，饑餓是全世界的問題，這與很多人所認(rèn)為的饑餓是發(fā)展中國家的問題這一觀點"相反"，所以答案選擇B．

點評 本題考查介詞短語的語義辨析，考生在平時的學(xué)習(xí)中應(yīng)注意積累相應(yīng)的短語和詞匯，并牢記其意思．在做題時，將短語的意思和題干相結(jié)合，從語法、句子結(jié)構(gòu)尤其是句意上去判斷，句意通順，符合邏輯，即正確答案．

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．

A．About two years．                   
B．Just one year．
C．Over three years．                  
D．Less than one year．

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
