  劍橋雅思14寫(xiě)作Task1題目：

  The diagram below shows how electricity is generated in a hydroelectric power station.Summarise the information by selecting and reporting the main features,and make comparisons where relevant.

  參考范文：

  The diagram shows the components of a hydroelectric power station and what happens there to generate electricity for the grid.

  At the 'beginning'of the diagram,we can clearly see that the high-level reservoir with main dam is situated and fed by a river.At the base of the dam is where the intake is located and it indicates that it is 'open'during the day.During the day,with the intake open,the flow of water down will be able to move the turbines that are attached to the generator that is,in turn,attached to power lines and the national grid.The water is stored in a low-level reservoir at this time.

  During the night,this process is reversed.The turbines are labelled as reversible,which means that they are used at night to reverse the direction of the water.It is unclear from the diagram exactly where the water goes after it is pumped up towards the intake and high-level reservoir,as the intake is labelled as 'closed'at night,but it is assumed that there is some mechanism allowing the water to be re-added.

  In summary,the flow of water shown shows a bi-directional pattern that allows water to be re-used in the creation of electricity for the national grid.(215 words)

  翻譯：

  示意圖顯示了水力發(fā)電站的組成部分,以及它如何給電力網(wǎng)發(fā)電。

  從示意圖的開(kāi)端我們可以清晰地看見(jiàn),帶有主壩的高處的蓄水池坐落在河邊,并且由這條河提供水源。大壩底部是進(jìn)口,白天的時(shí)候是打開(kāi)的。白天,進(jìn)口打開(kāi),下來(lái)的水流推動(dòng)和發(fā)電機(jī)連在一起的渦輪機(jī),同時(shí)發(fā)電機(jī)是和電源線以及國(guó)家電網(wǎng)連在一起的。此時(shí),水被儲(chǔ)存在低處的蓄水池中。

  到了夜晚,這一過(guò)程顛倒過(guò)來(lái)。渦輪機(jī)上寫(xiě)著“可逆”,這意味著晚上它們用來(lái)將水向相反的方向運(yùn)輸。雖然無(wú)法從該示意圖得知水流被抽入進(jìn)口和高處蓄水池的縣體位置(因?yàn)檫M(jìn)口處寫(xiě)著“晚上關(guān)閉")不過(guò)我認(rèn)為存在某種機(jī)械裝置,讓水重新流入蓄水池。

  總之，示意圖中的水流顯示的是定雙向模式,使得為國(guó)家電網(wǎng)發(fā)電的水可以重復(fù)利用。
