【正确答案】In the past 25 years, while pressing ahead with reform and opening up, China has put initially in place a socialist market economy, an economy that is open to the outside world. China's productive forces and overall national strength have been constantly enhanced. With various social undertakings developing in full swing, the Chinese people as a whole have made the historical leap from subsistence to modest prosperity. In the course of 25 years between 1978 and 2003, China's economy grew by an average annual rate of 9.4 percent, with its GDP, foreign trade and foreign exchange reserves jumping from 147.3 billion US dollars, 20.6 billion US dollars and 167 million US dollars to over 1.4 trillion US dollars, 851.2 billion US dollars and 403.3 billion US dollars respectively. China now is the world's sixth largest economy and the fourth largest trader. The reason why China has produced such tremendous changes is we have adhered to the road of building socialism with Chinese characteristics and persevered in reform and opening-up, thus galvanizing the Chinese people's initiative, enthusiasm and creativity. Though China has achieved impressive results in its development, there are still many acute problems, such as overpopulation, weak economic foundation, underdeveloped productivity, highly uneven development, and a fairly sharp contradiction between the country's ecological environment and natural resources on the one hand and its economic and social development on the other. China's per capita GDP, though reaching the record high of 1,000 US dollars last year, still ranks behind the 100th place in the world. To make China's modernization program a success and deliver a prosperous life for all the Chinese people still requires a long and uphill battle. We have already set a clear goal for the first 20 years of this century. Namely, in building a well-off society of a higher standard in an all-round way for the benefit of well over one billion Chinese people, we will quadruple the 2000 GDP to 4 trillion US dollars with a per capita GDP of 3,000 US dollars, further develop the economy, improve democracy, advance science and education, enrich culture, foster greater social harmony and upgrade the texture of life for the people. Over the past quarter of century, a socialist market economy has taken shape and an open economy has come into being amid/thanks to/as a result of China's steadfast/ongoing commitment to reform and opening up. During this timeframe, productivity and overall national strength of China have been on the rise, social programs have progressed across the board, and the people have witnessed/experienced/embraced a historic leapfrog from a decent life to one of moderate prosperity. Over the 25 years between 1978 and 2003, China's economy recorded an average annual growth rate of 9.4%, and its GDP surged to US$1.4 trillion from US$147.3 billion. The past 25 years also saw China's total foreign trade shoot up from US$20.6 billion to US$851.2 billion and its foreign exchange reserve soar to US$403.3 billion from a mere US$167 million. China today represents the 6th largest economy and the 4th biggest foreign trader in the world. The tremendous changes that have taken place in China can be best explained by the fact that we have unleashed/ unlocked people's enthusiasm, initiative and creativity through unwavering commitment to reform and opening up and to the building of socialism with distinctive Chinese features. For all the remarkable gains in development, China remains a country with a large population, weak economic foundation, underdeveloped productivity and rather uneven development among regions/huge inter-regional disparities. China is also struggling with an acute/salient imbalance between ecological wellbeing and natural resources on the one hand and socio-economic development on the other. China's per capita GDP has exceeded/topped US$1,000, but has yet to rank among top 100 on the world's list. That means China still has a long, hard journey to go before it can achieve full modernization and prosperity for all. We have established/identified/set our goals/visions for the first two decades of the new century/before 2020. That is, we must work to build a better-off society for over one billion people in all aspects by quadrupling the GDP by 2020 to US$4 trillion or US$3,000 in per capita terms, and making a visible difference/scale new heights in economic growth, democracy-building, scientific and educational advancement, cultural progress, social harmony and people's livelihood.
