英语翻译
The atmosphere is a blanket of gases around the Earth,For thousands of years these gases have kept the planet's temperature at about 15°C.How?By trapping some of the sun's heat,But now,because of pollution,there are more and more hot gases released into the atmosphere,This means that the Earth is getting hotter,A greenhouse becomes hot for the atmosphere,This means that the Earth is getting hotter,A greenhouse becomes hot for the same reason,Its glass lets the sun's heat pass through,then stops some of it from leaving,That's why scientists call the problem of the Earth's rising temperature "the Greenhouse Effect."
Many scientists agree that the Greenhouse Effect will add between 1.5°C-4°C to the Earth's temperature by 2030,This will change the weather everywhere,For example,the ice at the North and South poles will start to melt,And when that happens,the level of the sea will rise,If it rises one metre by 2030 there will be serious floods in many countries.
Then there is the problem of food,when the climate changes there will be less food in the world,At the moment areas like the Midwest of America and central Russia grow a lot of wheat,In the future that may change when the USA and Russia become too dry for farming,Other countries (like Canda and Sweden )will become wetter,but that won't help,The soil there isn't as rich,It won't be possible to grow the same amount of food as before.
We can't stop the Greenhouse Effect,However,we can slow it down if we use less fossil fuel,protect rain-forests,use more natural energy from the sun,sea and wind,and ban Freon in our lives.

大气层是环绕着地球的气体覆盖层.几千年来,这些气体使地球的温度保证在15°左右.这是怎么做到的呢?是通过限制太阳传递的热量.但是现在,由于污染,越来越多的热气停留在大气层.这就意味着地球会越变越热.温室由于大气的原因变得更热,这说明地球正在变得更热,温室由于同样的原因变热,温室的玻璃就会使更多太阳的热量穿过,然后使部分热量停留在温室里,这就是为什么科学家把地球温度升高的问题称作温室效应.
很多科学家认为温室效应会使地球的温度在2030年增加1.5°——4°,这将会使每一个地方的天气发生改变.比如,北极和南极的冰会开始融化,当这个发生的时候,海平线就会上升,如果海平线在2030年上升了一米,很多国家或城市会遭到严重的水灾.
还有一个问题就是食物.当气候发生改变,世界上的食物就会变得更少.现在在一些地方比如美国的中西部和俄罗斯的中心,有很多小麦生长.在未来,当美国和俄罗斯变得过于干燥以至于不适合农业时,这种小麦的生长将不复存在.其他的一些国家（比如加拿大和瑞典）会变得更加潮湿,但也没有任何益处.那儿的土地不够肥沃,要在那种植的食物和以前一样的产量也将变得不可能.
我们无法阻止温室效应.但是,如果我们减少对化石燃料的使用,保护雨林,更多地使用来自太阳、大海和风的自然资源,禁止氟利昂在生活里的使用,我们就可以减缓温室效应.
