  文本及疑难解析

  1. Producing enough energy to meet our needs has become a serious problem. Demand is rising rapidly, because of the world’s increasing population and expanding industry. Burning fossil fuels, like gas, coal and oil, seriously damages the environment and they’ll eventually run out. 生产能够满足我们需求的足够能源已经是个严重问题。需求一直在快速增长,因为人口在增长、工业在发展。燃烧矿物燃料,比如天然气、煤、石油,会严重破坏环境而且最终会被消耗殆尽。fossil 本意为“化石”,但 fossil fuel 指天然形成的古老的矿物燃料,而非化石可以当作燃料。

  2. Numerous devices have been invented to harvest wave energy. 许多设备被发明出来用于采集波浪能。harvest 用作动词可以表达“收获、收割、采集”。

  3. For tidal energy to be effective, the difference between high and low tides needs to be at least five metres, and this occurs naturally in only about forty places on Earth. But the right conditions can be created by constructing a tidal lagoon, an area of sea water separated from the sea. 为了使潮汐能有效果,高潮和低潮的差距需要有 5 米,地球上只有约 40 处这样的地貌是自然生成的。但是恰到好处的条件是可以通过建造一片隔离于海洋的潮汐泻湖创造出来的。separate from 为固定搭配。

  4. The breakwater will contain 16 hydro turbines, and as the tide rises, water rushes through the breakwater, activating the turbines, which turn a generator to produce electricity. 防波堤包含 16 个涡轮机,涨潮的时候,水冲破防波堤,激活涡轮机,从而启动发动机发电。

  5. Then, for three hours as the tide goes out, the water is held back within the breakwater, increasing the difference in water level, until it’s several metres higher within the lagoon than in the open sea. 三小时后落潮了,水被储藏在防波堤内,造成了水平面的差距。差距越来越大,直到泻湖内的水高出海平面许多米。

  6. Then in order to release the stored water, gates in the breakwater are opened. It pours powerfully out of the lagoon, driving the turbines in the breakwater in the opposite direction and again generating thousands of megawatts of electricity. 为了释放储存好的水,防波堤内的闸门会被打开。水汹涌地冲出泻湖,使防波堤内的涡轮机向相反方向转动,再而生产出几千兆瓦的电力。

  7. This system has quite a lot in its favour: unlike solar and wind energy it doesn’t depend on the weather; the turbines are operated without the need for fuel, so it doesn’t create any greenhouse gas emissions; and very little maintenance is needed. 这个系统有很多好处:不像太阳能和风能,它不受天气影响;涡轮机的运转不需要任何燃料,因此不排放任何温室气体;而且也不太需要维修。in one’s favour 指“有利,有益处”。
