大学英语4课后cloze及翻译原题带答案 Cloze1

In the 21st century, clouds and stormy weather no longer automatically bring operations to a halt or force a change in targets(目标). Technologies such as the Global Positioning System now allow cruise missiles(巡航导弹) and other smart weapons to home in on(瞄准并飞速接近) their targets. But the weather still is a factor that must be reckoned with, especially with precision-guided weapons that must be highlyaccurate (高度精确)to be effective.

Fortunately, the ability to obtain weather forecasts will get better. In the next few years, remote weather sensors(传感器)will grow rapidly on unmanned vehicles. This will create a network of observing platforms that will give commanders an instant overview of weather in

the battle zone(战场). In some areas you’ll have direct delivery of weather information straight from the computes to black boxes in aircraft and other vehicles. That will be especially important for target-bound aircraft(瞄准目标的飞行器).

Such technology will give whoever possess it a tremendous edge(优势)over their enemy and enable themto use developing weather conditions to their advantage. As we get superior satellites into space, we’ll gain huge advantages in observingmeteorological conditions in denied areas(盲区), where we don’t have people on the ground. And our modeling ability will continue to improve as our computers get more powerful. The past 10 years have witnessed a revolution in ourcommunicationsand computer abilities. It’s exciting to think of what the next 10 years will bring.

在第二十一世纪,云层和暴风雨天气不再自动带来业务停顿或迫使目标的变化(目标)。如全球定位系统现在允许巡航导弹技术(巡航导弹)等智能武器的家中(瞄准并飞速接近)目标。但天气仍然是一个因素不可忽视,尤其是精确制导武器,必须是非常准确的(高度精确)是有效的。

幸运的是,获取天气预报的能力将得到更好的。在接下来的几年中,远程气象传感器(传感器)将快速增长(无人的)无人驾驶车辆。这将创建一个观测平台,将给指挥官在战斗区天气即时网络(战场)。在一些地区,你会直接从计算的飞机和其他汽车黑匣子的天气信息直接传送。将目标束缚飞机尤其重要(瞄准目标的飞行器)。

这种技术会给谁拥有巨大的优势(优势)在他们的敌人,使他们利用气象条件对他们有利的发展。当我们得到优越的卫星送入太空,我们会观察气象条件的地区获得了巨大的优势(盲区否认),我们没有在地面上的人。我们的建模能力将继续为我们的电脑变得更强大的提高。过去10年见证了我们的通信革命(通讯)和计算机能力。令人兴奋的是未来10年会带来什么。
