　　13. Brain Drain
　　Brain drain is a delicate problem with which this country is confronted. In the last ten years
　　or so, a lot of scientists and technicians have swarmed into developed countries for further studies or research work, let alone numerous promising students. And there are no indications that they will be back home before long. This country has paid the expenses of training them but lost them. How did that come about?
　　It seems that it isn't impossible to solve the problem. The scientists and the like can be
　　attracted back home so long as great importance is attached to the intellectual's deserving treatment and effective measures are taken to provide them with excellent pay and agreeable conditions.
　　注：so long as 只要; great importance is attached to... 重视
　　effective measures 有效措施
　　14. Treasure Water
　　The availability of water has been an important factor in China's growth. China is blessed
　　with large supplies of fresh water. Such mighty rivers as the Yellow, the Yangtse and the Songhua irrigate the farming land of thousands of miles along them. In addition, the development of industry and the water supply of big cities are made possible largely by vast resources.
　　注：Treasure v 珍惜.
　　15. How to Solve Energy Crisis
　　Man is faced with a big problem—the energy crisis, which is becoming more and more
　　serious. First, with the increase in the world's population, the demand for fuels is growing steadily. Second, the rapid development of industry and agriculture calls for an increasing amount of coal, oil and natural gas.
　　注：energy 能源;crisis 危机
　　1、面临
　　2、解决
　　Confronted with the energy crisis, we should take a series of effective measures to save
　　energy. For one thing, it is high time that people all over the world realized the severe fact that our natural resources have been fixed since the earth was created. For another, the governments of all countries are supposed to lay down the rules and regulations to restrict the amount of gas used by cars. Finally, scientific researches should be encouraged to work out efficient methods of saving fuels and to seek new sources of energy.
　　Personally, I believe that solar energy is a possible source of clean, inexpensive and abundant
　　energy. It does not pollute the environment and costs only as much as the installation of solar panels to absorb the sun's rays. Consequently. I'm confident that a bright future is awaiting us because solar energy will be able to help us to solve the energy crisis.
　　注：personally 就我个人而言;solar 太阳能
