A firebreak is a narrow strip of land where people have taken away the plants and trees, so a fire on one side cannot easily jump to the other. Forest workers cut them before the dry season, or in a hurry when a wildfire is already moving. Grass, bushes, and dead wood are cleared; sometimes the ground is just bare earth or a dirt road.

A firebreak防火帶 is是 a narrow strip of land一條狹長的土地 where people have taken away the plants and trees人們把上面的植物和樹木清除掉, so a fire on one side cannot easily jump to the other這樣一邊的火就不容易跳到另一邊 Forest workers cut them林務工人會開闢它們 before the dry season在乾季之前, or in a hurry或是緊急 when a wildfire is already moving在野火已經蔓延時 Grass, bushes, and dead wood草、灌木和枯木 are cleared都會被清除; sometimes the ground is just bare earth or a dirt road有時候地面就只是裸露的泥土或一條土路

The fire reaches the empty strip and, if the break is wide enough and the wind is not too strong, it dies down instead of climbing into the next stand of trees.

The fire reaches the empty strip火到達這條空地 and, if the break is wide enough如果這條防火帶夠寬 and the wind is not too strong而且風不太強, it dies down它就會熄滅 instead of climbing into the next stand of trees而不是爬進下一片樹林

Though actually, a strong wind can still throw sparks across, so a firebreak helps; it does not magic the fire away.

Though actually不過其實, a strong wind can still throw sparks across強風還是能把火星吹過去, so a firebreak helps所以防火帶只是有幫助; it does not magic the fire away它沒辦法讓火整個消失

A wide road or a river can work as one too. The “break” is a break in the fire’s path.

A wide road or a river一條寬的馬路或一條河 can work as one too也可以當作防火帶 The "break"這個「break」 is a break in the fire's path指的就是切斷火的路徑
