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．"

6．Energy independence．It has a nice ring to it．Doesn't it？If you think so，you're not alone，because energy independence has been the dream of American president for decades，and never more so than in the past few years，when the most recent oil price shock has been partly responsible for kicking off the great recession．
"Energy independence"and its rhetorical （修辞的） companion"energy security"are，however，slippery concepts that are rarely though through．What is it we want independence from，exactly？
Most people would probably say that they want to be independent from imported oil．But there are reasons that we buy all that old from elsewhere．
The first reason is that we need it to keep our economy running．Yes，there is a trickle（涓涓细流）of biofuel（生物燃料）available，and more may become available，but most biofuels cause economic waste and environmental destruction．
Second，Americans have basically decided that they don't really want to produce all their own oil．They value the environmental quality they preserve over their oil imports from abroad．Vast areas of the United States are off-limits to oil exploration and production in the name of environmental protection．To what degree are Americans really willing to endure the environmental impacts of domestic energy production in order to cut back imports？
Third，there are benefits to trade．It allows for economic efficiency（效率），and when we buy things from places that have lower production costs than we do，we benefit．And although you don't read about this much，the United States is also a large exporter of oil products，selling about 2million barrels of petroleum products per day to about 90countries．
There is no question that the United States imports a great deal of energy and，in fact，relies on that steady flow to maintain its economy．When that flow is interrupted，we feel the pain in short supplies and higher prices，At the same time，we get massive economic benefits when we buy the most affordable energy on the world market and when we engage in energy trade around the world．

59．What does the author say about energy independence for America？A
A．It sounds very attractive．
B．It ensures national security．

A．It wants to expand its storage of crude oil．
B．Its own oil reserves are quickly running out．
C．Its own oil production falls short of demand．
D．It wants to keep its own environment undamaged．
61．What does the author say about oil trade？B
A．It proves profitable to both sides．
B．It improves economic efficiency．
C．It makes for economic development．
D．It saves the cost of oil exploration．
