The blanket of air
- A thin layer of gases wraps the whole planet.
- It gives us air to breathe and shields us from the Sun's rays.
- It holds our weather and keeps the Earth warm.
- This life-supporting blanket is the atmosphere.
空气的毯子
- 一层薄薄的气体包裹着整个星球。
- 它给我们呼吸的空气,保护我们免受太阳的射线。
- 它容纳我们的天气,让地球保持温暖。
- 这层支撑生命的毯子就是大气层。
What the atmosphere is
- The atmosphere 大气层 is the layer of gases surrounding Earth.
- It is about 78% nitrogen and 21% oxygen, plus small amounts of other gases.
- Held by gravity, it thins out with height into space.
- It is divided into layers with different properties.
大气层是什么
- 大气层(atmosphere)是包围地球的一层气体。
- 它大约 78% 是氮、21% 是氧,还有少量其他气体。
- 被重力抓住,它随高度变稀薄,直到太空。
- 它被分成性质不同的层。
Earth's atmosphere is… · 地球的大气层是……
The atmosphere is the blanket of gases (mostly nitrogen and oxygen) around Earth. · 大气层是地球周围气体(大部分是氮和氧)的毯子。
The troposphere: our home layer
- The troposphere 对流层 is the lowest layer, where we live.
- All weather — clouds, rain, storms — happens here.
- The air we breathe and most of the atmosphere's mass are in this layer.
- It gets colder as you go higher within it.
对流层:我们的家园层
- 对流层(troposphere)是最低层,我们生活在这里。
- 所有天气——云、雨、风暴——都发生在这里。
- 我们呼吸的空气和大气层的大部分质量都在这一层。
- 在这一层内,你越往高处走越冷。
Which layer holds our weather and the air we breathe? · 哪一层容纳我们的天气和我们呼吸的空气?
The troposphere is the lowest layer — where all weather happens and where we live. · 对流层是最低层——所有天气都发生在这里,我们也生活在这里。
The layer above the troposphere, which holds the protective ozone layer, is the . · 对流层之上、容纳保护性臭氧层的那一层是。
The stratosphere contains the ozone layer, which absorbs harmful ultraviolet rays. · 平流层含有臭氧层,它吸收有害的紫外线。
The stratosphere and ozone
- Above the troposphere lies the stratosphere 平流层.
- It holds the ozone layer 臭氧层, which absorbs harmful ultraviolet rays.
- The air here is calm, which is why jet planes cruise in its lower part.
- Without the ozone layer, life on the surface would be badly damaged.
平流层与臭氧
- 对流层之上是平流层(stratosphere)。
- 它容纳臭氧层(ozone layer),臭氧层吸收有害的紫外线。
- 这里的空气平静,这就是喷气式飞机在它下部巡航的原因。
- 没有臭氧层,地表上的生命会受到严重损害。
Which atmospheric layer? · 哪一层大气?
Sort each feature into the atmospheric layer where it is found. · 把每个特征归入它所在的大气层。
The atmosphere is mostly nitrogen, with about a fifth oxygen. · 大气层大部分是氮,大约五分之一是氧。
Air is about 78% nitrogen and 21% oxygen, with small amounts of other gases. · 空气大约 78% 是氮、21% 是氧,还有少量其他气体。
Select all · 所有 true statements about the atmosphere. · 选出关于大气层的所有正确说法。
The atmosphere is gas, not rock. The other three are correct. · 大气层是气体,不是岩石。其余三条正确。
Keep the two lower layers straight. The troposphere (bottom) is where weather and our air are. The stratosphere (above it) holds the ozone layer that blocks UV rays. Mixing them up is a common mistake — remember: weather down low, ozone up high.
把下面两层理清楚。对流层(底部)是天气和我们空气所在的地方。平流层(在它之上)容纳阻挡紫外线的臭氧层。把它们搞混是一个常见的错误——记住:天气在低处,臭氧在高处。
Why a jet flies so high:
- Storms and turbulence are trapped in the troposphere.
- By climbing into the calm lower stratosphere, planes rise above most weather.
- That is why a long flight often cruises "above the clouds" — it has climbed out of the weather layer.
喷气式飞机为什么飞这么高:
- 风暴和湍流被困在对流层里。
- 通过爬升到平静的平流层下部,飞机升到大多数天气之上。
- 这就是为什么长途飞行常常在"云层之上"巡航——它爬出了天气层。
