7．Researchers have developed new software using smart phones'GPS and imaging abilities that determine the exact location of distant objects as well as monitor the speed and direction of moving objects．The software could eventually allow smart phone armed soldiers to target the location of their enemies．On the home front，the software could be used by everyone，including golfers judging distance to the green and biologists documenting the location of a rare animal without disturbing it．
"The great advantage of a smart phone is that it provides so many tools in a single，readily available，relatively inexpensive package，"said Qia Wang，a doctoral student who led the development of the software．"For example，on the battlefield，a soldier needs a rangefinder（测距仪），compass，GPS and other tools to get information before calling in an air strike．With our software，the soldier can have all those instruments in one device that can be purchased off the shelf．When that soldier returns from war，she can use the same software to protect her family by clocking a speeder near her children's school and catching the criminal on video．"Wang and his colleagues developed their software to locate and track：
Targets of known size-When the size of the target is known，a single image is enough to pinpoint（确定） the target's location．
Targets of unknown size-If the exact size of a target is unknown，the software uses two images to triangulate（三角测量） the location of the target．
Moving targets-By taking a short video of a moving target，the smart phone software can calculate how fast the target is moving and in what direction it is going．
"Currently，our software is limited by the physical abilities of smart phone hardware，but the devices are improving rapidly，"Wang said．"We expect that improvements in GPS accuracy，battery life and camera resolution（分辨率） will allow our software to make even more accurate observations．"

分析 文章第一段讲了一款新软件的诞生和它的功能．第二、三两段写了该软件的优越之处．第四段至第六段写了它的具体工作原理．第七段写了该软件正在发展和它将来会更精确地定位和测速，文章强调这个软件可以在手机上运作
解答 62．D细节题．由第一段第一句"Researchers have developed new software using smart phones'GPS and imaging abilities that determine the exact location of distant objects as well as monitor the speed and direction of moving objects"可知新软件可以定位远距离的物体，D项符合题意．故正确答案为D．
63．C推断题．由第二段第一句"The great advantage of a Smartphone is that it provides so many tools in a single，readily available，relatively inexpensive package，"可知 Qia wang 主要说了该软件的优点．他举了士兵使用该软件可以不必费力气携带测距仪、指南针和定位系统的例子，说明了该软件的强大功能，即它的优点，所以C项符合题意．故正确答案为C．
64．A细节题．由第六段中的"By taking a short video of a moving target，the Smartphone software can calculate how fast the target is moving and in what direction it is going．"通过对移动的物体拍摄一段小视频，只能软件能够计算物体的速度，可知正确答案为A．
65．D推断题．由最后一段第一句"the devices are improving rapidly"可知，这个软件正在被优化；由最后一段最后一句"We expect that improvements in GPS accuracy，battery life and camera resolution will allow our software to make even more accurate observations．"可知 Qia Wang 的预期是该软件的准确度会提高，由此可见他对该软件的态度是乐观的，D项符合题意．故正确答案为D．
