Accommodation along the trek is in small tea houses, which offer a simple bed, a shower (gas heated water is often available) and food.

What we see as the magnificent Orion Nebula is just a dimple, a cavity, in the side of the cloud, filled with gas heated to glowing by the stars.

我们所看到的壮丽的猎户座星云，只是云层侧面的一个凹陷，一个空洞，充满了被恒星加热而发光的气体。

As it contracts, the atoms of the gas collide with each other more and more frequently and at greater and greater speeds—the gas heats up.

当它收缩时，气体原子以越来越快的速度相互碰撞越来越频繁——气体升温。

So, even though greenhouse gases heat the whole world roughly equally, cities - and especially poorer neighborhoods - are often hotter than suburban or rural areas by up to 15-20 degrees.

因此，尽管温室气体使整个世界的温度大致相等，但城市——尤其是较贫困的社区——通常比郊区或农村地区热 15-20 度。

" Not half so bad as all this dust, gas, heat, and noise. What do you suppose lungs are made of" ? demanded Mac, ready for a discussion then and there.

“不及所有这些灰尘、气体、热量和噪音的一半糟糕。你认为肺是由什么构成的” ？要求麦克，准备当场讨论。

For the poorest countries - most vulnerable to rising sea levels and new extremes of heat and drought - seeing a rapid fall in the gases heating the planet is a priority.

对于最贫穷的国家——最容易受到海平面上升和新的极端高温和干旱的影响——看到加热地球的气体迅速减少是当务之急。
