篇一：英语演讲(关于雾霾)
With the deteriorating of air quality in China, the number of days of fog-haze weather in some Chinese cities has soared up to now
In smog weather, many people choose to wear masks (口罩) when they go out. And just because of smog weather, many traffic accidents have happened，many flights are stopped, a lot of people have to stay at home because they think the air is dangerous, and more people with different diseases have to go to see the doctor. Smog is a big problem for our daily life.
First of all, let me introduce what is smog.is basically derived from the merging of two words; smoke and fog.
What we typically call smog today is a mixture of air pollutants. Smog which occurs mainly because of air pollution, can also be defined as a mixture of various gases with dust and water vapor. Smog also refers to hazy air that makes breathing difficult.
The the main component of fog haze is nitrogen dioxide, sulphur dioxide and pm
And obviously, pm mains particulate matter. Particulate matter-is ameasure of pollutants in the air and is commonly stated as PM2.5 or PM10.Pm2.5 is smaller than pm10. And it can reach your lungs when you don’t wear a face mask. From the picture we can see the pm2.5 with many shapes.
Next,let us know how the smog formed
The atmospheric pollutants or gases that form smog are released in the air when fuels are burnt. When sunlight and its heat react with these gases and fine particles in the atmosphere, smog is formed. It is purely caused by air pollution.
The main sources of these precursors are pollutants released directly into the air by gasoline and diesel-run vehicles, industrial plants and Straw Burning, and heating due to human activities.
For instance: The pie chart clearly shows that the automobile exhaust, burning coal, organic matter,Secondary sulphate ,nitrate and the dust are the main sources of regional air pollution in Beijing
The time that smog takes to form depends directly on the temperature. Temperature inversions are situations when warm air does not rise instead stays near the ground. During situations of temperature inversions if the wind is calm, smog may get trapped and remain over a place for days.
Smog is harmful and it is evident from the components that form it and effects that can happen from it. It is harmful to humans, animals, plants and the nature as a whole. Obviously,it may have a bad effect to
your respiratory system and cardiovascular system.And it will affect the traffic,the accident rate will increase due to the smog. In smog weather, the air is often with bacteria and viruses.so, it may spread diseases.
So how should we fight with the forceful impact of smog? It can be reduced by implementing modifications in your lifestyle.1.Search air quality index(AQI) first, reduce outdoor exercise if it is beyond 100
2.when it reach150 Wear N95/KN90 mask (while density of PM2.5)
3.Do not open window in the smog
4.Light diet and drink plenty of water
Finally I wish you good health andhappiness.
WHAT SHOULD THE GOVERNMENT DO TO REDUCE SMOG WEATHER? Develop and use new clean energy
Reduce the using of cars, developing the public transport
Increase the green area
Promote public supervision
篇二：英文 上海雾霾演讲稿
My speech
As we all know, a couple of days ago, a huge brownish haze covered Shanghai. Many people were forced to wear masks in order to protect themselves because the heavy haze can cause breathing problems as well diseases like headaches or even heart-attacks.
Due to the bad effects from the air pollution, a green and clear environment is the apple of the whole world’s eye. To avoid most of the pollution and help make our environment better, I have some advices: Firstly, we should go out as few times as possible. This is truly a way, but not a good one. Secondly, the government should bring out laws which limit the pollution of cars and factories. The air pollution will decrease sharply if the cars and factories stop letting out harmful gases. Thirdly, we should enhance the awareness of environment protection and build up the thought of have a green lifestyle. For middle school students like us, we should sort the trash and try to walk on foot or use bikes as transportation as much as possible.
Air pollution has become a serious problem here in China now. Considering health problems, some timely measures should be taken to overcome this problem.
I don’t have daydreams, wishing China will become a country with the best environment. I just hope we can breathe freely. All I want now is just a little fresh air. I think, perhaps most of you have the same thought…….
