The human race has experienced a consistent increase in population since the beginning of its history. Famine and disease have done little to offset(抵消) this steady increase. Too many people are added annually to the population of the world. So both the causes of population increase and the results of having more people are worth careful study.Culture evolution is the major factor responsible for population increase.Early in human development, people invented tools to hunt animals. Later they built shelters to protect themselves. Step by step, they made life easier. As a result, fewer died from natural forces, such as harsh climate and disease.In the past, when population grew, there was unexplored territory to inhabit. But now, almost all the habitable land has been explored.The world's population may reach 8.7 billion in 2033. It is clear that world population is a serious issue that needs careful attention. Human beings are unique to solve problems through cultural evolution.( 发展)Facing the world population explosion in the near future. We must carry out the birth control program in order to save the mankind and save the world.

Today the quality of our natural environment has become an important issue. The world population is rising so quickly that the world has become too crowded. We are using up our natural resources and at the same time polluting our environment with dangerous chemicals. If we continue to do this, life on earth cannot survive.Concerned people have made some progress in environmental protection.Governments of many countries have established laws to protect the air,forests and sea resources and to stop environmental pollution.Still more measures should be taken to solve environmental problems.People should be further educated to recognize the importance of the problems, to use modern methods of birth control, to conserve(保存) our natural resources and recycle(再循环) our products. We are sure that we can have a better and cleaner place in the future.

China, as a developing country, is determined to catch up with and even surpass the developed ones. I think that one of the best possible ways to do so is to give first priority(优先)to the development of culture, science and especially education.In modern times, when science and technology are making great progress,the education of the work force is of primary importance. Moreover, many of the success in advanced countries have demonstrated that a nation 's prosperity mainly depends on the quality of its labour force,namely those who have been well educated.In a developing country such as China, our investment in culture,education and science, and especially elementary education, must enjoy top priority. This is crucial(决定性的) for China to catch up with the developed nations in today's surging(汹涌的 ) waves of technological revolution. Otherwise, the gap between China and advanced countries will be widened rather than bridged.

Human life can not continue without science and technology. For many years, human society has developed with the advance of science and technology while the development of science and technology has in turn brought the process to mankind. So the life we are living now is more civilized than that of our fore fathers. The development of science and technology have brought about many changes in people's life. For example, the invention of television and space rocket have opened a new era for mankind. Through the use of TV people can hear the sound and learn the events happening thousands of miles away. Owing to the invention of spaceship and rocket, the dream of man's landing on the moon has now come true. Science and technology also play an important role in our socialist construction. We may say, our socialist construction is just like a skyscraper, while science and technology are its base. Without the base, the skyscraper can't be built. Therefore, we should try our best to contribute to the development of science and technology so as to provide a more solid base to build our country.

The open policy means that our country is open to investment, trade and technical and economic cooperation with other countries on the basis ofequality and mutual benefit. The purpose of open policy is to acquireadvanced technology, management skills to serve our socialistconstruction so as to promote the realization of the four modernizations.We must adhere to the open policy. Because economic relations betweenstates today have become increasingly close, and no country can possiblyadvance behind close doors. Only in this way, can we gradually close thegap between our country and the developed countries.Through the implementation of policy, we can learn advanced technologyand managerial expertise from abroad; make full use of the foreigncapitals to set up great enterprises; absorb useful and healthy ideas andnew knowledge of the modern civilization; and broaden our views and raise our level of competence.
