?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? In the picture it is a grey day and hazy weather.The pedestrians on the road wear gauze masks and it�s hard for them to breath. But there are still so many personal cars on the road , people in cars may not wear gauze masks,I think .

Hazy weather has become a frequent visitor to the weather forecast, and sunny weather become less and less.So people hate this bad,annoying,dirty weather. If we often breath such bad air?it will threaten our health. Because the bad weather cause a lot of diseases, such as respiratory disease, cardiovascular disease, cancer and so on. Hazy weather not only do damage to our life, but also blurs the sight of our eyes, even has a bad effect on our daily life.And opening windows everyday become luxurious. It�s a shock.Our heart is also covered a thick layer of soil. Living here we feel depressed.

What lead to the bad weather is mostly human pollution, for example industrial exhaust gas, burning, as well as automobile exhaust in this picture.The holders of cars is surging, which bring about not only the traffic problems, but also serious pollution problems.Nature�s purifying ability is out of her range. So citizens should have such consciousness, not their own convenience, but they should advocate green travel and give preference to public transportation. Only by doing this,can they make their own efforts to build up the blue sky once more.

Dear Bill,

I�m glad to receive your letter, thank you for your caring for the weather and my health. Now I�d like to tell you something about the smog.

Since the winter last year, the smog has occurred a lot of times. it has done great harm to our daily life. many traffic accidents happened just because of the heavy smog weather, more and more people have to go to see the doctor because the serious disease caused by the smog, quite a lot of flights have to be put off, a great number of people have to stay at home for fear of the poisonous air caused by the smog.

People have realized the great harm caused by the smog and the importance of protecting the environment. people all over the country are taking measures to reduce the smog weather. the government suggests people go to work or school with the public traffic, such as the bus and the underground. Also we should plant more trees.

According to me, I will go to school by bike or on foot, and I won�t throw the waste anywhere. in addition, I will tell the people I meet to protect the environment as possible as they can. would you like to tell me some good ideas? I�m looking forward to your reply.

Yours,

Pollution Haze

Recently, the topic of air pollution has again aroused more and more attention since pollution haze, a kind of weather, has appeared increasing frequently in our cities. Just as the picture showed, when pollution haze comes, the whole city was covered with suspended particles which can breath into our body causing heavy problem to our health.

Due to the bad effect from pollution haze, a green and clear environment, rather than anything else, turns to be an important role and a urgent issue in our daily lives. Meanwhile we just live in only an earth, if we didn�t try to protect our common hometown, we would have no place to settle.

Thus, we should take effective measures to rebuild our beautiful environment of the cities from now on.

In my opinion, law and regulations should be enforced by the government and authorities to control the emission of polluting gas. To ourselves, we should enhance the awareness of environment protection and choose a green lifestyle to make contribution to our earth day from day.

Now cars are increasing very fast. Factories are continuing polluting the air. Trees are being cut down. So the hazy weather is becoming more and more serious. It�s time for us to do something to protect the environment.

First of all, we�d better not travel by car unless it�s necessary. We can take the bus or the subway, walk or ride a bike if we don�t go far away. We can also set up a volunteer club and ask more people to join it. We can plant more trees, give the government advice to stop the factories polluting the air and water.

As people are knowing more about PM2.5, they are becoming more and more concerned about their living environment. As students, what should we do?

First, we should ride bikes or take buses to school. Riding bikes is also good for our health. We should try our best to advise our parents to drive less. Try to walk or ride bikes to work. Second, we�d better use both sides of the paper. Don�t waste paper. Third, we should save power. Remember to turn off the lights when we leave the classroom. At last, we should plant more trees and flowers.

If everyone makes a little effort, the world will be more and more beautiful.
