阅读理解。 China is a large country and has a population of about 1. 3 billion. But most people live in the east and the living standard (水平) is much higher than in the west. Recently, the Chinese government has decided to promote (促进) development in central and western China. The part includes 11 provinces (省) and autonomous regions (自治区) with a population of 285 million and an area of 5. 4 million square-kilometers. The rich nature resources in western China is one of the advantages for development. According to the plan, the government will focus on improving transportation. Highways and railways will be built. To protect nature, farmers will turn farmland back into forest. Since the western part is developing fast, all kinds of talents are badly needed. In June, 2003, several thousand college students chose to start their career in the west. They worked as volunteers. Some people even give up the chance of working in big companies in China' coastal (沿海的) cities. For example, Wang Fei was a student from Qinghua University. Before June, he had received a job offer in Shanghai. However, he turned down the offer. Instead, he became one of the 'Go West' volunteers. Since 2003, tens of thousands of college students have gone to the west. They are trying their best to make the west become more and more beautiful. We are sure that the development will be a great success. China will be richer and stronger. 1. According to this passage, we know that ________.
