Hello,everyone.it's my honor to stand here to make a speec for you guys .
Since 1976 China has changed enormously and rapidly.It has opened up to the rest of the world and has undergone a form of industrial revolution.It is now the world's fastest-growing economy with an average annual GDP growth rate above 10%.Most people live in the country but as the economy develops increasing numbers are being attracted to the towns and cities to find work and escape rural poverty.In 1950 only 12 per cent of the population lived in urban areas,now the urban population is 39%.By 2015 it is expected to be more than 50%.The opening of modern communication by road,rail,and air,and the development of mines and other sources of industrial raw materials have added to the importance of the marginal provinces of China and the outer territories of Tibet and Inner Mongolia.
