今天要给大家介绍的是:back-up system。
Back-up system在目前大量使用现代技术的情况下是经常听到的一种说法。它的意思是后备的设施。比如说,大型喷气式飞机都有一套后备的机械设备,要是主要的机械在飞行的过程中出现故障的话,这套后备的设备就可以马上运转,这样可以使飞机继续安全地飞行。Back-up system也就是这种后备的设施。航天飞机的内部就有好多后备的设备来保护宇航员。下面就是一个例子:
"On the second day of the flight, the space shuttle's main air-conditioning system broke down. But the astronauts switched on the back-up system and were able to continue the mission for another three days and land safely at Edwards Air Force Base."
这句话的意思是:“在航天飞机起飞后的第二天,飞机里的空调设备坏了。宇航员于是开动了后备的空调设备,这样他们才能再持续工作三天,然后安全地在爱德华兹空军基地降落。”
女:在当前高技术极为普遍的时代,如果没有后备的设施,有的时候非但会影响工作,而且还会造成很大的危险。下面就是一个例子。
"This airline pilot talked about getting ready to land that famous day when all the lights in New York went out. He said he was lucky the airport had a back-up system of its own generators -- otherwise he would have to try to land in total darkness."
这个人说:“大家都知道纽约发生停电, 全城陷入黑暗的那一天。这个飞行员谈到当天他准备降落的情景。他说,幸运的是,机场自己有后备的发电设备。否则,他得设法在黑暗里降落。”
