From VOA Learning English, this is the Technology Report.
The Federal Aviation Administration, or FAA, has chosen a university town in Virginia as one of six places to test drones. Drones are aircraft without human pilots. A drone can also be called an unmanned aircraft system, or UAS. The town, Blacksburg, is home to Virginia Tech University.
The university has flown and researched unmanned aircraft systems for years. But now, the research has more meaning. Researchers at Virginia Tech send reports to the FAA to assist the agency in the development of national drone rules. The FAA says most business drones cannot operate legally now. The agency plans to announce rules for how drones can share airspace in the United States with major airplane companies.
The leader of the Blacksburg test center is Rose Mooney. She says that her researchers are doing new things with UAS.
"UAS can do things that manned aircraft can't. Our first flight is going to be a larger aircraft that hasn't been flown unmanned in the national airspace."
Air information sensors are common on manned airplanes. But researchers at the Virginia Tech University test center have added a sensor to their drones. The sensor records air speed and altitude, the height of the flight. The information is sent through tubes to a computer that examines stability. All of the information is then sent to the FAA.
The federal agency may also rule on another device to guarantee greater safety. The device is a special eyewear that lets a person see the flight as if he or she is on the drone. Pilots on the ground can use this view to better direct the drone and keep it away from objects in the flight path.
Researcher Justin Stiltner says drones can be used to do jobs that are uninteresting, dirty or dangerous. They can fly into areas of radiation, or inside hurricanes or over croplands to examine corn. Professor Craig Woosley says farm studies are the main goal.
"We need to do better at how we do agriculture so we can continue to improve crop yields and that drives us toward ever more and more technology. "
Rose Mooney thinks using drones is a huge step forward in the flight industry. But drone use will not change until the FAA publishes new rules. And that is not expected to happen until late 2015.

内容解析
1.Pilots on the ground can use this view to better direct the drone and keep it away from objects in the flight path.
keep away (from) (使)远离，(使)不接近；(使)不在：
You must keep away from the dog.
你千万别靠近那条狗。
Keep the children away from the fire.
让孩子离火远一点。
I haven't seen you for ages. What's been keeping you away?
我已经好久没见到你了，为什么最近没露面?

这里是美国之音慢速英语科技报道。
美国联邦航空管理局(FAA)选择维吉尼亚州的一个大学城作为测试无人机的6个场地之一。无人机是没有飞行员操作的飞机，也称为“无人飞机系统”(UAS)。弗吉尼亚理工大学位于布莱克斯堡。
这所大学所年来一直从事无人机系统的飞行和研究，但现在研究的意义更多。维吉尼亚理工大学的研究者们向FAA发送报告，帮助该机构制定国家无人机条例。FAA称大多数商用无人机现在还无法合法经营，该机构准备宣布有关无人机如何同主要航空公司共享美国领空的规定。
罗斯·穆尼是布莱克斯堡测试中心负责人，她说她的研究团队在用无人机测试新的东西。
“无人机可以做有人驾驶机无法做到的事情，我们的第一个飞机将是从未在国家领空无人飞行过的大飞机。”
航空信息传感器在有人驾驶机上很常见，但维吉尼亚理工大学测试中心的研究者们给无人机也配备了传感器。这个传感器能记录飞行速度和高度。这些信息通过管道传输到检查稳定性的电脑上，然后所有这些信息被传送给FAA。
航空管理局可能会就另一种设备出台规定以确保更大的安全性，这种设备是一种特殊的眼睛，戴上这种眼睛的人能看到飞行的情况，就好像自己在无人机上一样。地面的飞行员可以使用这种设备来更好地指挥无人机，使之避开航行路线上的物体。
研究员贾斯汀·斯特勒说，无人机可以用来做些无趣、肮脏或危险的工作。它们可以飞到有辐射的地区，或是飓风内部，或者田野上空去检查作物。克雷格·伍斯利教授说农田研究使主要目标。
“我们需要在农业方面做得更好，这样我们就能持续提高作物产量，并驱动我们创造更多科技。”
罗斯·穆尼认为航空工业使用无人机是巨大的进步，但在FAA出台新规定之前，无人机的使用不会发生改变，预计新法规将在2015年年底出台。
