Article: BEIJING - Alarmed by the overreaching ambitions of many Chinese provinces to grow at all cost, China's top economic chief is calling on officials to calm down and spare a thought for the environment. Zhang Ping, who heads China's National Development and Reform Commission, the central economic planning agency, said only five or six of China's 30 provinces are targeting annual economic growth of 8 percent or 9 percent. The remaining provinces are aiming for growth rates of more than 10 percent this year, with some wanting to double economic output in the coming five years. "China has a planned energy supply of about 4 billion cubic tons of coal equivalent for the next five years, and this is not enough to meet demands for economic growth to double," he was quoted as saying on the news portal Sina. com. Beijing is increasingly concerned with the ambitions of Chinese provinces across the country to chase high growth despite the central government's urgent request for a more moderate and sustainable pace of expansion. Years of rapid economic growth have _ China's environment, with Beijing trying to remove some of the damage now. It has an annual growth target of 7 percent for the next five years, well down from last year's 10 percent. Zhang said Beijing has asked local governments to take into account the supply of "energy, environment, water and land" to set more reasonable growth target. Question: The general idea of the whole passage can be that _ . Options: A: China's economy is increasing at a fast speed. B: China's top chief lays more emphasis on the environment C: economic high growth should go hand in hand with environment concern. D: all Chinese provinces should slow down their economic growth rates

One end of the lamp wick is immersed(............) in oil and the other end is not immersed. When you light the end which is not immersed, it will burst into flame . This is because the oil is able to rise up the lamp wick thus helping it to burn. In the same way, if you immerse the end of a piece of chalk into a glass of water, the water will soon climb up the chalk making it wet. If a piece of ordinary glass tubing is heated in a gas flame until it becomes soft,it can be pull into a tube of a very small hole. Immerse the tube into water or any other liquid which wets glass, you will find that the liquid rises to a height of several centimeters. This is known as capillary action. The liquid rises because there is an attractive force between the liquid and the glass. The attractive force depends on the diameter of the tube and the type of liquid used. Question: The last sentence means that _ . Options: A: the thinner the diameter, the greater the attractive force B: the diameter of the tube and the kind of the liquid decide the greatness of the force C: the thinner the diameter, the smaller the attractive force D: oil climbs up higher than water
