New Development for Central and Western China

The Chinese government has recently decided to develop central and western China.

This part of China includes 9 provinces and autonomous regions and one municipality, covering an area of 5.4 million square kilometers with a population of 285 million.

The government will pay special attention to their transportation system. Some highways and railways will be built. To protect nature, farmers will return farmland to forest. Also, measures should be taken to prevent pollution. Western China is rich in natural resources, which can be exploited and made full use of. To meet the needs of the development, all kinds of experts and skilled workers are to be brought in.

We have every reason to believe that the efforts of the government will be a great success. As a result of the great project, the central and western regions of China will surely achieve greater and faster development in the new century. The people will have a better life and China will surely be richer and stronger.

Problems in the New Century (举例法说明文)

Write an expository essay on the problems man will be faced with in the new century.

In the new century, human beings will be filled with hope and live more advanced life. What used to be depicted in science fictions can be the reality of the near future. However, man will also have to confront with some problems that will curtail(剥夺)human beings of their existence.

First of all, pollution of all forms such as land pollution, noise pollution, air pollution and water pollution are worsening with each passing day. People complain all over the world that it is becoming harder to breathe and water is turning undrinkable. Also forests are being felled at a very fast rate. The pollutions are getting so terrible that in some countries we can’t find clean and clear rivers and white clouds in the sky! When the children draw a picture of their surroundings, they paint the green trees in gray, the red sun in gray, everything in gray, and they can’t find a pure environment except in the books.

Additionally, the explosion of population in some parts of the world is manifesting its terrible results. Human beings wil1 have outgrown the earth’s resources, and people will run a high risk of starvation and diseases resulting from overcrowding. In due course, man would be forced out of the earth if the present trend were not reversed.

What is more, in the past century we had many disastrous wars. But there is still potential that the atomic bomb will be used by some politicians in order to keep regional hegemony. If it should happen, the exp1osion could easily lead to the destruction of civilization.

More seriously, the depersonalization of human relationships and the weakening of spiritual values are aggravating due to the stress caused by the busy schedules and the extreme pursuit of money. This will further contribute to man’s isolation and loneliness.

Apparently, with all these problems facing human beings, it seems to be overwhelmingly urgent to conquer them one by one because we have only one earth and it is our home. In the new century, we must try our best to heal the world and make it a better place for you, for me and for the children who will come to this world.
