nuclear power plants are unlikely to melt down. the average reactor holds enough fuel to keep running for two years. but without humans consuming the power generated by the plant, the reactors will automatically shut down into a safe mode in as little as two days. 核电厂不会那么容易失去燃料，一般的反应堆就有着能够用上两年的核燃料，但如果没有人来消耗这些能量，反应堆在两天内便会停止工作，而进入安全模式。
★★★ turbine
★★★ lubrication
★ maintain
Even wind generation can't last forever. the turbines require bearings and lubrication of those bearings in order to keep operating. if there's no one around to maintain the turbines, the electricity doesn't get produced. 即使是风力发电机组,也不会一直工作下去,涡轮的旋转需轴承和润滑油,如果没有人来维护，很快风力发电机组就无法工作。
★★★ outage
★★★ grid
★ contribute to
★★★ a cascade of

★ reservoir
★★★ turbine generator
There's water in the reservoir keeps supplying the water to the hydro turbine generators. these generators are operating automatically and that would continue as long as all of the systems are functioning normally. 水库里流动的水带动涡轮发电机不停的工作，这些发电机自动工作，只要系统不出问题，他们能够一直工作下去。
★ tunnel
★★ drainage
★ cable
★ transportation
Beneath all the major cities, there's a complex network of underground tunnels, and these are there for drainage purposes or for cabling purposes, and in the case of the big cities, for transportation as well. 世界上各大城市的地底下都有复杂的地下隧道系统，有的用来作为排水系统，有些用来排线布线，在一些大城市，也是交通运输的通道。
★★★ water table
★ pump
There are many of those sit below the level of the water table and in order to keep them dry, we have to have a system of pumps that are switched on when necessary to drain the tunnels. 大部分的隧道都在地下水位以下，为保持隧道不浸水，都会有一套抽水装置，在必要的时候抽掉隧道里的水，以保证地下隧道干燥和正常运行。
★★ rot
