China has become one of the world’s fastest growing economies.Since 1979,China has been moving away from its communist state-controlled economy,adopting some principles of free trade,and privatizing many businesses.The country’s move toward free markets will be continued.However,the economic growth combined with many problems such as pollution and income inequality.
污染
Pollution is a major problem in many industrialised cities.Increased car ownership has led to problems of smog and worsening air quality.Pollution also occurs from China’s vast industrial sector.Often regulation of pollution is very limited with untreated sewage often been poured directly into rivers.
人均收入不平衡
China’s economic growth has benefited the south and eastern regions more than anywhere else.This has created a growing disparity between north and south.The agricultural north has,by contrast,been left behind.Many farmers struggle to make a living.Therefore,this has encouraged a migration of workers from north to south.China has struggled to deal with this regional inequality.
这里我举了2个例子,第一个是污染,第二个是南北方人的均收入不平衡.你随便选个例子就够字数,不需要2个例子都说.
