Wind power is an ancient source of energy we may return in the near future.

B
Particles from car exhausts generate more persistent clouds but less rain, new research suggests. Furthermore, putting more of these particles into the atmosphere reduces the low-level winds, which could reduce the amount of wind power available in very polluted regions. The dry but populated regions may therefore suffer a triple blow as a result of vehicle pollution：less water, less hydropower and less wind energy.
Scientists studied the effects of aerosol（浮质）pollution from cars and industry. They correlated satellite data on wind speeds and the amount of aerosol particles in the atmosphere above the South Coast Basin in California and above China. Results showed that higher concentrations of aerosols were closely associated with slower ground winds. Scientists then used computer models to support the idea that there was a cause and effect relationship behind this correlation.
Particles floating in the atmosphere block energy from the Sun, preventing it from warming the surface of the Earth. Cooler surface temperatures during the day means the low—level and slow moving air does not rise up and mix with the faster winds at higher altitudes. Slower winds also induce less evaporation from oceans, rivers and lakes. And finally, once clouds have formed, they store less moisture in the form of rain. This is because raindrops form around small particles— dust, for instance, or pollution. With more particles in the atmosphere, it takes longer for enough water to condense（凝结）onto a particle to form a raindrop. And if the cloud of fine droplets（小滴）moves to a drier area before its would-be rain can rail, the moisture evaporates once more and the cloud disappears.
Scientists note their new work does not contradict previous findings that suggest global warming might lead to more tropical storms, because there is far less particulate（微粒的）pollution over the oceans.

BEIJING, March 1 (Xinhua)-China's top economic planning body has confirmed the government will take concrete actions to develop a low-carbon economy after it promised to considerably reduce carbon emission (排放) at last year's Copenhagen Climate Conference.
China would include the low-carbon targets in the 12th five-year plan for national economic development (2011-2015) to build an energy-saving, ecologically friendly society, the National Development and Reform Commission (NDRC) said in a report to the Standing Committee of the 11th National People's Congress (NPC).
The report said the government would launch a series of technological and financial support policies to promote the use of non-fossil, renewable energies including wind, solar, biomass, geothermal (地热) and nuclear power, aiming to increase its percentage of primary energy consumption to about 15 percent by 2020 from 9.9 percent at the end of last year.
China's installed wind power capacity (容量) reached 15 million kilowatts, with 10 million kilowatts under construction at the end of June 2009, while nuclear power under construction, installed hydro-electric power capacity and solar heating collection areas were the highest in the world, it said.
The commission was also planning to make a catalog (目录) of emissions of greenhouse gases in an effort to build a monitoring and checking system to cut carbon emissions.
The economic planner decided to control unnecessary construction and industries with surplus (多余的)production capacities, such as steel, cement and electrolytic aluminum, to promote the energy efficiency and environmental protection.
The government had drafted a plan on regional development to transfer industries in eastern areas to central and western regions.
The State Council announced in November that China would reduce the intensity of carbon dioxide emissions per unit of GDP in 2020 by 40 to 45 percent compared with the level of 2005.
67.Which of the following best summarizes the low-carbon economy China is to develop?
A.Energy-saving and ecologically friendly.
B.Promoting the use of clean energy.
C.Developing the industry in the wild west.
D.Reducing carbon emissions per unit of GDP by 40 to 50 percent.
68.Which of the following does NOT belong to China's low-carbon measures mentioned in the text?
A.Limiting the use of nuclear power and other primary energy.
B.Setting up a system to monitor and check carbon emission.
C.Controlling unnecessary construction and industries with extra production capacities.
D.Planning to move industries from eastern areas to central and western regions.
69.If you are planning to start your own business in line with the low-carbon economy, which is the best choice?
A. An iron and steel plant. B. A petrochemical works.
C. A solar heating company. D. A construction company.
70.The passage is mainly about .
A. China's plan of economy development in the 12th five-year plan
B. China's efforts to build up a low-carbon economy
C. NDRC's reaction to Copenhagen Climate Conference
D. NDRC's plan handed over to the Standing committee of 11th NPC
