保护环境英语作文 篇1
In recent years there has been a marked growth of fire accidents in big cities of our country. Almost every day we see fire engines rushing through the streets. Fires have not only resulted in heavy economic losses but also injured and killed many people.
What are the causes of fire accidents? Most of the fires are brought about by carelessness and violation of fire safety regulations. Others are due to the poor quality of home electrical appliances. By the way, some people don't know how to use them properly. Besides,there are quite a few businesses which focus so much of their attention on profits that they tend to neglect and even ignore fire precautions.
In my opinion, in order to prevent fires we should first of all foster people's sense of fire prevention. The second thing we have to do is to increase the number of professional fire fighters, to whom regular training courses should be offered. Finally, we are to improve the existing fire engines and add more fire facilities to high-rise buildings. In this way, a reliable fire prevention system will be formed.

From this cartoon, we can see that at the top end of the river,is a chemical factory and a paperrnaking factory which send out and poisonous wastes. And the river has been seriously polluted, be seen from the color of it. Along this "black" river, there area few people selling fresh water which must have been taken fromfar away places.
At the first glance, it is very strange to us how can people sell water along the river, but this is the case, because the water in this river is undrinkable. This presents a serious social problem--environmental pollution. With the development of economy, our living standards have been greatly improved. But we can' t ignore the fact the air we take in and the water we drink today are not as fresh and clean as they used tobe.
Some kinds of pollution can even be deadly to people. It is high time that we took some measures to solve the problem.I think we can first call people's attention to this problem so thatthey will be aware of the serious consequences of it. Then,we can passcertain laws to restrain the factories from sending out wastes.
Finally,we can do more resarch work to find out ways to deal with the wastes.
