4） The Fight Against Crime

　　Today the crime rate in some of our cities seems to be rising. Many citizens complain about the thefts and robberies which take place in their street blocks. Therefore， more and more people are appealing to the authorities to take strong measures to reduce the crime rate.

　　Faced with criminals， different people have different attitudes towards them. Some become so frightened that they tend to give up fighting or to turn a blind eve to the criminals. Others， however， are brave enough to fight the criminals even at the risk of their own lives. In their eyes， responsibility is the most important of all the values that hold honest people together Without it there can be no self-respect， no trust， no law-and， ultimately， no society. There is no doubt that they set a good example for all of us to follow.

　　As far as I am concerned， my suggestions are as follow. In the first place， every one of us should receive a law education. Secondly， criminals must be punished severely. Finally， it is urgent to set up a foundation to reward those who fight criminals. In this way we can stand up to any crime and smash it.

　　5） Challenges of Environmental Issues

　　Environmental protection has aroused great concern among people. In many cities， especially in big populous cities， environmental pollution has become really serious. For example， an urban population of 12 million and 1.4 minion vehicles in Beijing puts great pressure on resources and the environment， The underground water level in Beijing has continued to decrease in recent years due to excessive use. Coal burning， exhaust emissions from vehicles and factories also intensify the city‘s environmental problems. We have to pay the historical debts we owe to the environment because of early rapid economic development.

　　However， pollution control does not have to hinder economic development. In a sense， it is a stimulation to the economy because pollution controls motivate enterprises to aim for higher industrial standards and start a material and resource efficient production. The exhaust control on vehicles can be cited as an example. Some municipal governments require that the pollutant level in vehicle emissions be controlled to reduce air pollution. Unleaded gasoline has also been promoted during the past year. As a result， automobile and chemical factories have to enhance their production technology to meet the demand.

　　Now some municipal governments have also taken such measures to stop the pollution as replacing coal with natural gas， reducing dust and deforestation to improve the lives of residents. In Beijing， 30 per cent of fuel used in urban centers will come from natural gas. Low sulfur coal is replacing high sulfur coal for factories. Many small boilers and kitchen ranges in restaurants and dining halls have been replaced by gas ovens.

　　As we can see that the measures have been effectively combating pollution. The air sulfur dioxide density has been on the decline since this year， and the density of total suspended particles and carbon monoxide bas been kept on the same level as last year. Though the density of nitrogen oxides continues to increase because of the rising of the number of automobiles， the degree of growth has been reduced.

　　Despite the progress some big cities have achieved in improving the local environment， we believe that big city planners should adopt a comprehensive environmental policy， which is more important than the detailed measures and achievement.
