1、If others treat you well, you must be able to repay you in the future. If others treat you badly, you must strive to be able to raise your eyebrows one day.简单易用轻享办公（页眉可删）气候变暖的英文演讲稿 气候变暖的英文演讲稿1People around the world may feel that the climate has been getting steadily warmer and warmer in recent year
2、s. Places which used to be abundant in snowfall have frequently experienced snowfree(无雪的) winters. Drought lasts longer in some dry areas. People find that without air conditioners they could hardly work or fall asleep on hotter summer daysg.The side effects of global warming are alarminS. A warmer
3、global climate melts the ice caps, raising sea levels. What is more, it disturbs weather patterns, causing droughts, severe storms, hurricanes (飓风). People suffer a lot from disasters relevant to global warming.To stop global warming we should make immediate and continual efforts. We hope the situat
4、ion will soon change. Global warming catches and holds our concern, for it affects us and will affect our later generations. We cannot wait any longer. Do it right now.气候变暖的英文演讲稿2Many people believe that human activity is causing the earths temperature to rise. They say that this global warming will
5、 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 earths temperature is rapidly changing. As a result there has been a lot of climate change such as heat waves, droughts and f
6、loods. Scientists believe that this is the result of human activity, which is polluting the Earths 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 i
7、nformed.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 di
8、scuss 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.Fi
9、nally, 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 enco
10、urage 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
11、 that governments can do to prevent global warming. They should involve companies, support scientists and encourage individuals to protect the planet.气候变暖的英文演讲稿3After investigation, we found that caused the main reason for the increase of greenhouse gases is human activity. Carbon dioxide, for examp
12、le, before the human society to realize industrialization in the early 19th century, the concentration of carbon dioxide in the atmosphere to 270 parts per million, and in 1988 to rise to 350 PPM. Atmospheric co2 concentration increased there are two main reasons: first, the dramatic increase in pop
13、ulation and the development of industrialization, human society, consumption of fossil fuels has increased dramatically, combustion produces a large amount of carbon dioxide into the atmosphere, increase the concentration of carbon dioxide in the atmosphere: second forest reduces the amount of carbo
14、n dioxide absorbed by plants use, a speed reduction in carbon dioxide is consumed, also leading to higher concentration of carbon dioxide in the atmosphere. Greenhouse gases than carbon dioxide, such as methane, CFCS (freon), nitrogen oxide and so on also need to increase a different level.Although
15、there are many uncertainties, it is clear that global warming on climate, rainfall, and the influence of sea level and the resulting impact on human settlements and the ecosystem is extremely complex, must be given the attention they deserve. Think this kind of influence is irrelevant in the long ru
16、n view is irresponsible.The main cause of global warming, the atmosphere is destroyed, serious pollution and greenhouse effect caused by global warming could affect global warming will bring to the earth and human complex potential impact, both positive and there are also negative. Such as temperatu
17、re height, deputy polar regions may be more suitable for human habitation, under appropriate conditions, higher co2 concentration can promote the photosynthesis, which plants have a higher rate of carbon sequestration, lead to the increase of plant growth, namely the stimulation effect of carbon dio
18、xide, which is the positive impact of global warming. But compared with the positive impact, the negative impact of global warming on human activity will be more vast and far-reaching.气候变暖的英文演讲稿4There is little doubt that the planet is warming. Over the last century, the planets temperature has rise
19、n by around 1 degree fahrenheit (0.6 of a degree celsius). The warmest since the mid 1800s was the 1990s. The hottest years recorded were 1997, 1998, 2001, 2002, 2003.The United Nations panel on climate change projects that the global temperatures will rise 3-10 degrees fahrenheit by the centurys en
20、d - enough to have the polar caps all but melted. If the ice caps melt, a vast majority of our countries borders will be under water. Monuments and great buildings, as well as homes and lives will be under water, including New York City.So now we know what some of the causes are for global warming,
21、how can we as individuals do our part to help save the planet?The answer is simpler than you may think. You dont have to go miles away from home to protest, or spend masses of money. If you try to follow the few simple steps that I shall now give you, you will have started to help us all.Firstly, pl
22、ant a tree. This could be easier than it sounds. Join or help out a local wildlife group and ask to plant a tree. Trees, when fully grown, will help keep the planet cooler. On the same point, you could protest against the demolition of the rainforests. This is the same principle, we need the trees t
23、o cool our planet and yet they are chopping them down to create roads or homes.Something as simple as walking instead of taking the car will help reduce pollution. As well as stopping pollution, you are giving yourself exercise, something important for our bodies. So the next time you get into your
24、car, or your motorbike, think - do I have to make this journey by vehicle or can I walk?When you are at home, and your getting a little cold. Put a jumper on and do not adjust the heating. The extra heat produced by our homes also affects the planet. So try wearing an extra layer in winter.If possib
25、le, buy your fruit and vegetables from local suppliers. And try to avoid imported goods. The more foreign food that we import the more pollution from aeroplanes and boats it will create.Keeping to the speed limit can also help the environment. The more you speed the more petrol you are going to use,
26、 making the pollution higher. Also, SUVs make about six times their own weight in CO2 each year. A small efficient diesel car covering the same distance not only uses much less fuel; it makes two thirds less.If possible use solar energy, after all it is free; all you need to buy is the equipment. Yo
27、u can get much of your hot water and heating from the sun and even generate electricity.Reduce, reuse and recycle. Only buy what you need; dont stock the cupboards with things you may or may not use. Reuse whatever you can, like containers and paper, and recycle what you cannot reuse. It really is a
28、s simple as that.Finally turning off unused sources of power such as televisions and heaters will help the environment, as well as save you money.If everybody stuck to these rules, we would be doing a great thing by protecting the earth. So please take into consideration what I have said, and try to
29、 do your part. After all, it will be our next generation that will feel the effects.气候变暖的英文演讲稿5With 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 gl
30、obal 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.气候变暖的英文演讲稿
