9. The World Population Explosion

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.

10. Opening-door Policy is the Only Way to Make China Strong. Modern Chinese history leads us to the conclusion that socialism， not capitalism is best for China. But how a socialist China should look at capitalism and more importantly， make use of the better side of capitalism for its own advantage is of vital（至关） importance to the country. As far as our country’s economic construction is concerned， taking advantage of the part of capitalism that is useful to us means we need to develop foreign trade， introduce advanced technology and better management， and make use of foreign funds. It also means we can absorb some of the economic theories， and make use of those economic policies， methods and measures that comply with（遵循） the law of mass production and a commodity economy. By opening our windows wider to the outside world， people can learn more about other peoples and learn to make sensible judgments. Absorbing the better part of the cultures of other people to enrich ourselves is the best way to safeguard our socialist culture. So taking advantage of capitalism and stepping up economic reforms is the only way to make China strong. Closing the county to international exchanges will only keep it weak.
