阅读核心词汇五A few years after World War II finished, scientists spoke with great eagerness about the use of nuclear power (核能源) as source of energy. Within twenty years, they said, nuclear would take the place of coal, gas and oil as a source of power at homes and in industry. This promise has never been carried out and there are now serious doubts that it ever will be. Nuclear power plants are used to produce energy in some wealthier countries, but the cost is high.Although safety measures have been taken, radiation leaks (辐射泄漏) have taken place and workers have been killed or affected. The problem of getting rid of the nuclear waste has proved most difficult. There is a limit to the amount of waste materials which can be buried in the ground or poured on the sea-bed. These methods may also cause more problems. Waste materials polluted by radiation may remain dangerous for 200 years or more.It is no surprise that scientists have now turned to the sun and the sea as sources of power. The sun shines day after day almost wastefully, providing us with energy far beyond all our needs.New words and expressions eagerness (n.) 渴望;热心;热切She shows great eagerness for success. eager (adj.) 渴望的，急切的He is eager for success. nuclear (adj.) 原子核的，原子能的nuclear power 核能源radiation (n.) 辐射 radiative (adj.) 辐射的能源energy矿物质能源 mineral energy太阳能solar energy风能 wind energy水能water energy电能 electric energy自然资源natural resourcesource (n.) 来源Where is the source of the Rhine? at source 在源头Is the water polluted at source? take the place of 取代，替代The new always take the place of the old. 近：replacecoal(n.) 煤The country is rich in oil and coal. 石油 petroleum / oil天然气natural gasindustry (n.) 工业agriculture (n.) 农业commerce (n.) 商业service industry 服务性行业promise (n.)/ (v.) 承诺，允诺，约定Once he made a promise, he would stick to it.
