2
people can also use the energy in moving water to produce electrical energy.
3
Electricity produced using moving water is called hydroelectricity or hydropower.
4
Hydroelectricity uses the kinetic energy in flowing rivers and streams.
5
The water is often held in large dams which allow people to control the flow of water.
6
When the water in a dam is released, it pushes past generators that convert kinetic energy into electricity.
7
The electricity travels along power lines to power stations, where it is sent along an electrical grid to our homes and cities.
8
A few of the advantages of hydroelectricity are that it is renewable,
9
it provides consistent power, and like solar energy and wind turbines, it does not release any pollutants into the air.
10
The disadvantages of hydroelectricity are that it requires a lot of water.
11
The water is either dammed up or diverted from its natural course.
12

什麼是跟讀法？

跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
