| You have plans for future study. A country also has plans. At the beginning of March, the 2006 National People's Congress (NPC, 全国人民代表大会) passed China's 11th Five-Year Plan. The plan promises higher incomes (收入), better education and less pollution by 2010. If the promises all come true, Chinese people's lives will change a lot. Let's take Cai Wenkang as an example. Roads and water The 13-year-old boy is a junior one student in Hunan. His parents are both farmers. According to the plan, Cai's family will benefit a lot. For example, the government will provide safe drinking water to 100 million countryside people by 2010. Asphalt (沥青) roads will be built to connect all towns and villages. So, Cai will soon drink running water instead of well water. Trips on the bus will be more comfortable. More money Also, Cai's parents don't need to worry about money to pay to send their son to school in two years. The plan promises that by the end of 2007, countryside students won't need to pay school fees until they finish junior high. People's lives will continue to improve. Each year, people will get 5 per cent more money, says the plan. That is to say, if an average Chinese family made about 10,000 yuan in 2005, in 2010 the family could earn 12,800 yuan a year. At that time, as the plan describes, China should see great progress in science. Chinese astronauts would land on the moon. China might build its own airliners (客机). So in 2010, if Cai goes to university by air, he probably would find the airplane is not from Boeing or Air Bus. It's made in China. |
