参考答案:
China is a developing country with a strong sense of responsibility.We are ready to make contribution to promote win-win cooperation for sustainable development.A sound and rapidly growing Chinese economy is helpful for the economic development of the region and that of the world at large.With an average annual growth rate of 9.4% in the past 20-old years of reform and opening-up,China has succeeded in meeting the basic needs for food,clothing and shelter of its population and providing,on the whole,a moderately comfortable livelihood for its over one billion people.China's economy right now is in good shape,though not problem-free.Thanks to our macro-economic measure,the unhealthy and unstable factors in the economy have been brought under effective control.
不仅成功解决了十几亿人的温饱问题，而且使中国人民的生活总体上达到小康水平。
分析：
句中的如“温饱”和“小康”都是极具特色的中国时政用语，英语中没有现成的对应词，翻译时只能意译。“温饱”可以理解为“满足了基本吃，穿，住，”而“小康”可以理解为“过得比较舒服”。
