四级英语作文民生、、和谐、环保、人性化”的素材
The Car and Pollution
Most Americans would find it hard to think what life would look like without a car.However,some have realized the serious problem of the air pollution caused by the car.The polluted air becomes poisonous and dangerous to health.
One way to get rid of the polluted air is to build a car that does not pollute.That’s what several of the large factories have been trying to do.But to build a clean car is easier said than done.Progress in this field has been slow.
Another way is to take the place of the car engine by something.Now inventors are working on steam cars as well as electric cars.Many makers believe that it will take years to develop a useful model that pleases men.
To prevent the world from being polluted by cars,we make some changes in the way many of us live.Americans,for example,have to reduce the number of their total cars.They are encouraged to travel and to work by bicycle.It is thought to help man to keep the air clean.
But this change does not come easily.A large number of workers might find themselves without jobs if a car factory closed.Thus the problem of air pollution would become less important than that of unemployment.
Although cars have led us to better life,they have also brought us new problems.
Natural Resources
Nature has provided us with many kinds of resources.Almost everything we use in our everyday life comes from Nature.The food we eat,the water we drink,the clothes we wear,the concrete and bricks to build our houses,the materials to make bikes we ride,etc.all come originally from Nature.
People have been making use of these natural supplies for thousands of years.With the development of technology and the increase of the population,the amount and range of materials taken has increased.It is estimated that this tread will continue in the years to come.
However,natural resources are not in exhaustible.Some resources are already nearly used up.For example,the end of the world’s fuel is already within sight.Such an essential daily item as water is in short supply in many parts of the world.We can no longer thoughtlessly use the many resources provided by Nature.We must learn to conserve what remains.
We Have Only One World
When industries grow,pollution also grows.Today the problem of environment has become more and more important.The world population is rising so quickly that the world has become too crowded.We are using up our natural resources too quickly and at the same time we are polluting our environment with dangerous chemicals.If we don’t take action immediately,then we will destroy our only world.
Man has made great progress in environment protection.Government of many countries has established laws to protect the forest and sea resource and to stop the environmental pollution.
Still more measures should be taken to solve the problem.First,we should start by educating the public about the hazards of pollution.The government on its part should also design stricter laws.This is not only for our own generation but also for the future generation to come.
It is necessary to protect our nature environment.We must begin now to protect our only world.
Make The Best Use of Our Land
It is the land that has been providing us with everything we need for centuries.In other words,almost everything we use daily comes from the land directly or indirectly.The food,clothes,houses,even the books and furniture are all supplied by the land.But the limited land is decreasing at a surprising speed.With the expanding of the cities,the development of the industry and over population,lots of large pieces of good farmland are being turned into residential areas with many houses and apartment buildings,or industrial areas,or warehouses.
Therefore some measures must be taken to stop the abusing of our farmland.On the other hand,we should let everyone realize the danger of being short of land.And also we should educate them how to make better use of our land.
