News report:


The central government decided to cut down on pollution by calling for a Car Free Day last September. Since then, in the city of Kunming, Yunnan Province, the last Saturday of every month is officially "car free", apart from public transportation, police and emergency vehicles, making Kunming the first city in China to adopt this initiative on a regular basis. Frequent vehicle restrictions have triggered debate among the public. Some questioned the legitimacy of this move. Some asked whether confining their cars at home has deprived them of their rights on free use of private possessions. Others complained of China’ s far less developed public transportation infrastructure in some areas.

Topic: The Car Free Day Initiative


Questions for Reference:
1. Do you agree with the practice of Car Free Day in major cities in China on a regular basis Why or why not
2. Shall we simply restrict the use of private cars or reduce the production of cars Give your reasons.
3. Do you have any suggestions for or even better solutions to those traffic and environmental problems
