With the development of economy, more and more greenhouse gases are being discharged into the air. CO2 makes up about 70% of the greenhouse gases, which is considered to be one of the greatest causes of global warming. It has harmful effects, causing the sea level to rise and many natural disasters to strike.

So we must take effective measures to save our planet. First, we should use more clean energy and less coal and oil. Second, we should go to work on foot or by bus instead of driving a car if possible. Third, we should plant more trees, because plants can turn CO2 into oxygen. More importantly, we should form the habit of saving energy in our daily life.

Many people believe that human activity is causing the earth’s temperature to rise. They say that this global warming will have dreadful consequences for our environment, such as drought and flooding.

What should governments do to help prevent global warming? Give reasons for your suggestions.

The earth’s temperature is rapidly changing. As a result there has been a lot of climate change such as heat waves, droughts and floods. Scientists believe that this is the result of human activity, which is polluting the Earth’s atmosphere. This could become a disaster if governments do not act to help prevent global warming. They can act in three ways; by supporting research, by making laws and by keeping the general public informed.

Firstly, governments can support research. For example, they should encourage companies to develop vehicles that cause less pollution. They should also support alternative sources of electricity from wind and water rather than from oil and coal. As well, they should sponsor conferences to discuss the effects of greenhouse gas emissions and possible solutions to the problem.

Secondly, they should make laws that limit the amount of greenhouse gases that companies can emit. Private companies should be rewarded for following these laws. They should also be punished for creating pollution.

Finally, everybody is affected by global warming. Therefore, it is important that governments involve individuals in the problem solving process. For example they should encourage households to save as much energy as possible by using more efficient light bulbs or less hot water. They should also encourage the public to recycle, and this should be compulsory for everyone. Another way of saving energy is by public transport systems. Governments should spend money on public transport to make it as easy as possible for the public to save energy.

In summary, it is clear that there are a lot of things that governments can do to prevent global warming. They should involve companies, support scientists and encourage individuals to protect the planet.

As more and more countries become industrialized,global environment has been inevitably changed.And we are just experiencing the altered climate.Human activity is affecting global climate.Many scientists have predicated that global temperature will continue to rise in the foreseeable future because greenhouse gas emission is still increasing.

Now there is a growing awareness that climate change is definitely not confined to a certain region or country.

However,it is a problem all countries are involved.Most people would agree that as the planet warms and the sea ice is melting,polar bears are vulnerable to lose habitat,even threatening our home around the coastal areas.It is time we took measures to protect our environment.

There is no denying that industrial emissions have been the dominant influence on climate change for the past 50years,overwhelming natural forces .To improve this situation, First of all, Ultimately, we,everyone on this blue planet are supposed to promote and carry out"low-carbon"lifestyle as an obligation.Secondly,carbon emission reduction must be put into implement,especially reducing fuel consumption and exhaust emissions,and it a wise choice for us to use renewable energy resources.Moreover,global climate summit are expected to play a significant part in urging involved powers to Carry out the state strategy of sustainable development so that our environment can be back to normal gradually.

Greenhouse gas emission is but one of the many effects for the climate change.Another is excessive deforestation.And the Amazon tropic rain forest has seen man's greediness.Just imagine what would be like if our forest coverage rate were what it was 20 years ago?The answer is quite clear that global temperature would be lower and many species may not die out.Therefore,we must quit using disposable packaging and dishware and encourage of employment of environmentally-friendly materials.Besides,people ought to develop an awareness of environmental protection and cherish forests resources.Of course supporting recycling is also a good alternative way.

In present case ,yet it could go a long way for us to recover our environment from climate change,we are obligated to dedicate ourselves to go for a harmonious planet.In addition,we have every reason to try our best to protect our environment.I believe the new environment is in store with our efforts.

No one，regardless of race， religion or nationality ， can deny that the world we live in is becoming increasing intolerable because of the effects of global warming. According to many experts，even greater impact are still on the way.

There are numerous cauuses for this problem. On one hand, human-related emission of carbon int the atmosphere is causeing, and will in the future cause, significant global warming according to the theory. On the other hand, the lack of knowledge about the importance of protecting environment hinders the solving of the problem.

It is urgent that immediate and effective actions should be taken right away. First, more trees need to be planted to help improve and beautiful the environment .

I often see on television, network is now the holes of the earth has been destroyed by human, if we are in different heart to protect it, the destruction of the earth will be completely in the near future. Faster and faster, with the development of human science and technology science and the negative effect gradually manifested, then let me give you a few examples to illustrate why experts predicted that the earth will be gone after so many years.

First of all, global warming is one example, soak in the hot weather in summer air conditioning becomes a new "hobby", but what do people ever thought of air conditioning can bring negative effect? Gas air conditioning to contain large amounts of methane, to the outside is the leading cause of global warming gases, methane and air conditioning will waste a lot of electricity, so try to avoid using the air conditioning or appropriate use.

Another reason is that carbon dioxide, automobile exhaust and factory waste gas containing a large amount of carbon dioxide, and carbon dioxide are most likely to lead to global warming. Cars now, too much exhaust serious affect our nong cough, throat inflammation... . According to concerning sectional statistic China's per capita emissions of carbon dioxide emissions every year 2. 51 tons a year! The changes in the harsh environment around us.

More important reason is that: reduce forest, farmland, water damage and serious water pollution, fresh water supply is a problem, many parts of the draft has become a big problem. Now countries are massive effort, demanding, and costs "of the south-north water diversion project".

In order to save the planet, people all over the world should be: don't open air conditioning, use recycled environmental protection bags, don't use plastic bags, take the bus, don't throw waste batteries... Such as the dribs and drabs in life. In fact, environmental protection is not difficult, as long as you support is the best gift you give earth environmental protection, take action, this is a powerful force!

在这一则报导中，我学到很多事，但我第一个想到的是，造成地球变暖的原因是二氧化碳增加。

In this paper, I have learned a lot of things, but I think the first one is the cause of global warming, the increase of carbon dioxide.

为什么二氧化碳会增加呢?我想到的原因是人们常常开车、养食家畜、工厂大量排放黑烟……等。不过这些是大家可以一起解决，说不定可以改善地球继续暖化，例如：目的地很近的话可以骑自行车;目的地很远的话，可以搭乘公共交通运输工具;家畜的排泄物经过处理再排入河内;工厂可以建一座废弃处理厂……等。

Why carbon dioxide will increase? I think the reason is often drive, raising livestock, food factory emissions of smoke...... Etc.. But these are all can solve them together, it can improve the Earth continues to warm, for example: the destination is close enough to ride a bike; destination long enough, can take the public transport; waste livestock treated and then discharged into the Hanoi factory; to build a waste treatment plant.

请大家不要小看二氧化碳的威力，等到海平面上升、都市浸水和农地淹没，到最后就会面临粮食不足的危机了。请大家跟我一起喊：“停止伤害地球的行为吧!我们居住的地球只有一个。”

Please do not underestimate the power of carbon dioxide, when the sea level rise, urban water and farmland submerged, eventually facing food shortage. Please call with me: "stop the harm to the earth's behavior! Only one earth on which we live. "

The cold winter has passed, but this winter with snow is not, is not how cold the weather, why is this so?

I asked my mother, my mother said: "I don't know, you go online to check." I opened the computer, input -- global warming. There have been many answers on the layout.

Because of human destruction of forests and other greenhouse gases from the burning of when, because these greenhouse gases with high transmittance in the visible light radiation from the sun, and the earth is reflected is highly absorbent, can strongly absorb infrared radiation on the ground, the greenhouse effect is often said that the "". Global warming may lead to consequences, will lead to a global redistribution of precipitation, melting glaciers and permafrost, rising sea levels, damage the balance of the ecosystem and the human food supply and living environment.Global warming is not only harmful to humans, but also endanger the survival of animals. For example, the polar bear, because of global warming, melting glaciers and polar bear hunting fish more difficult, and the ice melting fast, this continues, sooner or later the polar bears extinct species like the polar bear, Arctic wolf, Arctic animals are penguins.

Want to stop global warming, we should save every drop of water; plant more trees to reduce desertification; do not use disposable convenient bag; reduce the emission of carbon dioxide. I appeal to our homes, we act together now!

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: "stop hurt the behavior of the earth! The earth on which we live is only one."

As is subtly revealed in the cartoons above, global warming is a real threat to our world. In the first drawing, the glaciers in the polar region are rapidly melting owing to global warming. In the second picture, a homeless polar bear is staying on an isolated big block of ice.

The purpose of these portrayals is to show us that global warming is a looming threat to people all over the world. To begin with, global warming leads to the rise of sea levels. Large sections Chinese coastal regions would gradually disappear under rising sea levels because of global warming, severely impairing the country’s social and economic progress. China’s long coastline is the base for about 70% of the large cities, over half of the domestic population and nearly 60% of the national economy. With comparatively-advanced social, economic and cultural developments, China’s off-shore regions will suffer great losses if the sea level does not cease rising. In addition, global warming increases the possibility and intensity of extreme weather such as hurricanes and snowstorms. Hurricanes and typhoons have become stronger and longer-lasting over the past 30 years. These upswings correlate with a rise in sea surface temperatures due to global warming.

Taking into account the devastating effects of global warming, we can draw the conclusion that global warming is a great threat to our world. Facing the growing menace of global warming, more scientific and active preventive measures should be taken on a larger scale to change for the better.

正如上述漫画生动所示，全球变暖是当今世界的真正威胁。在图一中，由于全球变暖，极地冰川正在加剧融化。在图二中，一只无家可归的北极熊呆在一块孤立的大冰块上。

这些漫画的目的是告诉我们：全球气候变暖对全世界的人们来说是迫在眉睫的威胁。首先，全球气候变暖会导致海平面的上升。由于气候变暖，中国大多数沿海地区都将随着海平面的.上升逐渐消失，严重危害了国家的社会和经济发展。中国漫长的海岸线遍布着中国70%的大城市，人口数量占到全国总人口的一半以上，控制着国家经济的将近60%。这些城市的社会、经济和文化发展程度相对先进，如果海平面继续保持上升的话，那么对于中国的内陆城市来说将会承受巨大的损失。其次，全球气候变暖加大了出现极端天气的可能性并加重其强烈程度，例如飓风、雪灾。在最近30年里，飓风和台风持续的时间越来越长，强度也越来越大。这是与全球气候变暖所带来的海平面温度上升紧密联系的。

考虑到全球气候变暖带来的这些毁灭性影响，我们可以得出结论：全球气候变暖是全球的一大威胁。面临着日益增长的威胁，我们应该大规模采取更加积极、科学的预防性措施来促使其向更好的方向发展。

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。

When global warming, the world have changed dramatically.

The Antarctic ice and snow melt, human feeling will be under water, it is human to take the consequences. Arctic overlord, the polar bear also gradually extinction due to global warming. Has been the mother to a pair of scissors to bear, baby bear curiously ask: "mother, with scissors stem what ah?" Mom replied in a tone of command: "quick shearing, longer so thick hair will be hot dead!" Naive to bear looked at his mom, "we live in the ice and snow, how can heat? This is our coat, without it will be cold, can't cut!" Mother bear tone with a sad and sigh: "global warming, in does not adapt, now I'm afraid go!"

Global warming, the polar bear can't find food, even little bear, it is be compelled helpless! Humans shall make profound reflection to your behavior, but, when global warming, human couldn't realize his mistake! Only know no longer suffer from the cold in winter, the temperature rose, the cold has gone, only the immediate interests, didn't know that will be far away from the white snow, originally should be open the flowers in the winter.

When global warming, I hope this to human consciousness already consequences. Early up, to stop all this happen!

当全球气候变暖时，世界发生了巨变。

南极，冰雪融化，人类感觉将要处于冰水之中，这是人类自食其果。北极的霸主北极熊，也因全球变暖而逐渐走向灭绝。一直熊妈妈向小熊递来一把剪刀，熊宝宝好奇地问：“妈妈，用剪刀干什么呀?”妈妈以命令的语气回答：“快剪毛，再长这么厚的毛会被热死的!”小熊天真的望着妈妈：“我们住在冰天雪地里，怎么会热呢?这是我们的外衣，没有它会受冻的，不能剪!”熊妈妈的语气中带点悲伤和叹息：“现在全球变暖，在不适应，恐怕就走向灭亡了!”

全球变暖，北极熊无法找到食物，甚至食用小熊，这是被逼无奈呀!人类应当对自己的行为进行深刻的反省，可是，当全球变暖时，人类还无法意识到自己的错误!只知道冬天不再受寒风的折磨，温度上升了，寒冷已离去，只顾着眼前利益，可不知道以后将远离那洁白的雪，原本应在寒冬中开放的花。

当全球变暖时，希望人类早已意识这以后果。趁早弥补，阻止这一切的发生!
