A turbine is a machine with a wheel of blades that spins when something pushes past it — water, steam, wind, or hot gas. The spinning is the whole point: that turning movement is then used to do work, most often to make electricity. Think of a pinwheel toy, but heavy, made of metal, and enormous.

A turbineturbine is a machine with a wheel of blades是一種裝了一圈葉片的機器 that spins when something pushes past it當有東西從旁邊推過去的時候就會轉動 — water, steam, wind, or hot gas像水、蒸氣、風，或熱氣體. The spinning is the whole point重點就在於這個轉動: that turning movement is then used to do work這個轉動的動作接著被拿去做功 most often to make electricity最常見的是用來發電. Think of想像 a pinwheel toy一個玩具風車, but heavy, made of metal, and enormous只是更重、是金屬做的、而且非常巨大

Nearly all the electricity you use at home was made by a turbine of some kind: steam from burning coal or from a nuclear reactor spins one, falling water in a dam spins one, wind spins one. Jet planes have them too — inside a jet engine, hot gas rushing out spins a turbine, which drives the fan at the front.

Nearly all the electricity you use at home你家裡用的電幾乎全部 was made by a turbine of some kind都是某種 turbine 發出來的: steam from burning coal or from a nuclear reactor spins one燒煤或核反應爐產生的蒸氣會讓一個轉動, falling water in a dam spins one水壩裡落下的水會讓一個轉動, wind spins one風也會讓一個轉動. Jet planes have them too噴射機裡也有 — inside a jet engine在噴射引擎裡面, hot gas rushing out spins a turbine衝出來的熱氣體會讓一個 turbine 轉動, which drives the fan at the front而這個 turbine 帶動前面的風扇

So you will meet the word in compounds far more often than alone: 'wind turbine', 'steam turbine', 'gas turbine', 'turbine blade'. It is a normal technical word, not formal or fancy, and engineers say it every day. In everyday Taiwanese life the one you actually see is the wind turbine — those tall white three-blade towers along the west coast.

So you will meet the word in compounds far more often than alone所以你遇到這個字時，大多是跟別的字合在一起，而不是單獨出現: 'wind turbine', 'steam turbine', 'gas turbine', 'turbine blade'像「wind turbine」、「steam turbine」、「gas turbine」、「turbine blade」. It它 is a normal technical word是一個普通的技術用語, not formal or fancy不特別正式也不花俏, and engineers say it every day工程師每天都在講. In everyday Taiwanese life在台灣的日常生活裡 the one you actually see你實際會看到的 is the wind turbine就是 wind turbine（風力發電機） — those tall white three-blade towers along the west coast就是西部海岸那些高高的白色三葉片高塔

Note the shape: a turbine takes energy OUT of a moving fluid. A fan or a propeller is the same idea running backwards — it uses energy to push air.

Note the shape請注意這個形狀: a turbine takes energy OUT of a moving fluidturbine 是從流動的流體裡把能量取出來. A fan or a propeller風扇或螺旋槳 is the same idea running backwards是同樣的概念反過來跑 — it uses energy to push air它是用能量去推動空氣

People sometimes call a wind turbine a windmill, though actually a windmill was for grinding grain, not making power.

People sometimes call有人有時候會把 a wind turbine風力渦輪機 a windmill叫成 windmill（風車）, though actually不過事實上 a windmill was for grinding grain, not making power windmill 是用來磨穀物的，不是用來發電的
