Earth’s temperature begins with the Sun. Roughly 30 percent of incoming sunlight is reflected back into space by bright surfaces like clouds and ice. Of the remaining 70 percent, most is absorbed by the land and ocean, and the rest is absorbed by the atmosphere. The absorbed solar energy heats our planet.

地球的温度开始太阳。大约百分之30的太阳光被反射回太空的光明面与云冰。在余下的百分之70，多数是由陆地和海洋吸收，其余的被大气层吸收。吸收太阳能加热我们的星球。

As the rocks, the air, and the seas warm, they radiate “heat” energy (thermal infrared radiation). From the surface, this energy travels into the atmosphere where much of it is absorbed by water vapor and long-lived greenhouse gases such as carbon dioxide and methane.

当岩石，空气，和温暖的海洋，他们辐射热能源(热辐射)。从表面上看，这种能量进入大气层，大部分是由水蒸气和长寿命的温室气体如二氧化碳和甲烷的吸收。

When they absorb the energy radiating from Earth’s surface, microscopic water or greenhouse gas molecules turn into tiny heaters― like the bricks in a fireplace, they radiate heat even after the fire goes out. They radiate in all directions. The energy that radiates back toward Earth heats both the lower atmosphere and the surface, enhancing the heating they get from direct sunlight.

当他们吸收辐射能量从地球表面，微观水或温室气体分子变成小加热器-就像在壁炉的砖，他们散发热量，即使在火熄灭。他们在所有方向辐射。能量辐射回地球加热低层大气和表面，增强他们从阳光直射加热。

This absorption and radiation of heat by the atmosphere―the natural greenhouse effect―is beneficial for life on Earth. If there were no greenhouse effect, the Earth’s average surface temperature would be a very chilly -18°C (0°F) instead of the comfortable 15°C (59°F) that it is today.

这种吸收和辐射热的气氛自然温室效应有利于地球上的生命。如果没有温室效应，地球表面的平均温度将是一个非常寒冷的18°C(0°F)而不是舒适的15°C(59°F)，它是今天。

Good morning. I’m Li Hua from Fujian, China. It’s my great honor to be here to say something about the global water shortage and ways of dealing with it.

As we know, the global water shortage is becoming increasingly sever mainly due to global warming, environmental pollution and the ever-increasing population. Therefore, it’s high time we did something about it.

Firstly, an effective way, I think, is to reserve water in a scientific way for future use. Secondly, new methods need to be developed to use the existing waster resources, for example, turning sea water into fresh water. Thirdly, we must stoop water pollution by law. Last but not least, it’s everyone’s responsibility to make good use of water, such as recycling and saving water in our daily life.

In conclusion, people around the world should be aware of the real situation of water shortage, protect the present water resources and explore potential ones scientifically.

早上好。我是李华来自中国福建。这是我的荣幸在这里谈谈全球水资源短缺和处理它的方法。

正如我们所知，全球水资源短缺越来越严重主要是由于全球变暖，环境污染和不断增长的人口。因此，是时候我们做了些什么。

我认为，首先，一个有效的方法就是储备水科学的方法，以供将来使用。其次，需要开发的新方法使用现有的浪费资源，例如，将海水转化为淡水。第三，我们必须弯腰水污染由法律规定的。最后但并非最不重要，它是每个人的责任，充分利用水，如回收和节约水在我们的日常生活中。

总之，全世界的人们应该意识到水资源短缺的真实情况，保护水资源和潜在的科学探索。

In this report, I learned a lot of things, but my first thought is that the cause of global warming is carbon dioxide increases.

Why is carbon dioxide will increase? I think the reason is that people often feed drive, raising livestock, factories discharge smoke... And so on. But these are all can be solved together, perhaps can improve the earth continued warming, for example: close to the destination can ride a bike, Destination is far away, you can use public transport; Livestock waste processed into Hanoi again; Factory can build a waste treatment plant... And so on.

Please do not underestimate the power of carbon dioxide, wait until the sea level rise, urban flooding and flooded farmland, in the end would have faced the crisis of insufficient food. Please join me shout: xxxstop hurt the behavior of the earth! The earth on which we live is only
