(1) Until the very latest moment of his existence man has been bound to the planet on which he originated and developed. Now he had the capability to leave that planet and move out into the universe to those worlds which he has known previously only directly. Men have explored parts of the moon put spaceships in orbit around another planet and possibly within the decade will land into another planet and explore it. Can we be too bold as to suggest that we may be able to colonize other planet within the not - too - distant future ﹖ Some have advocated such a procedure as a solution to the population problem. ship the excess people off to the moon. But we must keep in head the billions of dollars we might spend in carrying out the project. To maintain the earth's population at its present level, we would have to blast off into space 7500 people every hour of every day of the year. Why are we spending so little money on space exploration﹖ Consider the great need for improving many aspects of the global environment, one is surely justified in his concern for the money and resources that they are poured into the space exploration efforts. But perhaps we should look at both sides of the coin before arriving hasty conclusions.

2 More people die of tuberculosis(结核病)than of any other disease caused by a single agent .This has probably been the case in quite a while. During the early stages of the industrial revolution, perhaps one in every seventh deaths in Europe's crowded cities were caused by the disease .From now on, though western eyes missing the global picture saw the trouble going into decline .With occasional breaks forward the rates of death and infection in the Europe and America dropped steadily trough the 19th and 20th centuries. In the 1950s, the introduction of antibiotics(抗菌素)strengthened the trend in rich countries and the antibiotics were allowed to be imported to poor countries. Medical researchers declared victory and withdrew, they are wrong .In the mid-1980s the frequency of infections and deaths started to pick up again around the world .Where tuberculosis vanished, it came back in many places where it had never been away ,it grew better. The World Health Organization estimates that 1.7 billion people a third of the earth's population suffer from tuberculosis. Even when the infection rated was falling population growth kept the number of clinical cases more or less constantly at 8 million a year .Around 3 million of those people died nearly all of them in poor countries .
