国庆”一词，本指国家喜庆之事，最早见于西晋。西晋的文学家陆机在《五等诸侯论》一文中就曾有“国庆独飨其利，主忧莫与其害”的记载、我国封建时代、国家喜庆的大事，莫大过于帝王的登基、诞辰（清朝称皇帝的生日为万岁节）等。因而我国古代把皇帝即位、诞辰称为“国庆”。今天称国家建立的纪念日为国庆。

As early as 2500 years ago, the ancient Greek philosopher 'Telles' (Thales, 640-546B.C.) knew that the amber friction will attract the hair or wood chips, this phenomenon is called static electricity (electricITy static).
In 1600, British doctor Gilbert (1544 ~ 1603) do years of experiment, found the "power", "electrical attraction", and many other phenomena, and the first to use the "power", "electric attraction" and other special terms, so many says he is the father of the study of electricity.
In the mid eighteenth Century, on the other side of the ocean of the United States, the great scientist Franklin made a number of experiments, to further reveal the nature of the electricity, and put forward the current term.
1831, Faraday made the world's first generator. He found that the first magnet through a closed circuit, the line will have a current generated, this effect is called electromagnetic inction. It is generally believed that Faraday's law of electromagnetic inction is one of his greatest contributions.
1866 German SIEMENS (Siemens) made the world's first instrial generator.
早在2500多年前，古希腊的哲学家‘泰勒斯’（Thales,640-546B.C.）就知道琥珀的摩擦会吸引绒毛或木屑，这种现象称为静电(static electricITy)。
公元1600年，英国医生吉尔伯特（1544～1603）做了多年的实验，发现了“电力”，“电吸引”等许多现象，并最先使用了“电力”、“电吸引”等专用术语，因此许多人称他是电学研究之父。
18世纪中叶，在大洋彼岸的美国，大电学家富兰克林又做了多次实验，进一步揭示了电的性质，并提出了电流这一术语。
1831年，法拉第制出了世界上最早的第一台发电机。他发现第一块磁铁穿过一个闭合线路时，线路内就会有电流产生，这个效应叫电磁感应。一般认为法拉第的电磁感应定律是他的一项最伟大的贡献。
1866年德国人西门子（Siemens）制成世界上第一台工业用发电机。

『玖』 有关地球起源的英语作文
地球形成时基本上是各种石质物的混合物，如果积聚过程持续~年，则短寿命放射性元素的衰变和固体颗粒动能的影响都不大。初始地球的平均温度估计不超过1000℃，所以全部处于固态。形成后，由于长寿命放射性物质的衰变和引力位能的释放，内部慢慢增温，以致原始地球所含的铁元素转化成液态，某些铁的氧化物也将还原。
When the earth was formed basically is a mixture of various stone, if the accumulation process continues in ~, short life of radioactive elements decay and solid particle kinetic energy are not. The average temperature of the earth's initial estimate does not exceed 1000 degrees, so all in solid state. After the formation, e to the release of long-lived radioactive substances decay and gravitational potential energy, internal slowly warming, that the primitive earth contains iron is converted to liquid form, some iron oxides will also be reced.
液态铁由于密度大而流向地心，形成地核（这个过程何时开始，现 在已否结束，意见颇有分歧）。由于重的物质向地心集中，释放的位能可使地球的温度升高约2000℃。这就促进了化学分异过程，由地幔中分出地壳。地壳岩石受到大气和水的风化和侵蚀，产生了沉积和沉积岩，后者受到地下排出的气体和溶液，以及温、压的作用发生了变质而形成了变质岩。
The liquid iron because of its high density and flow into the heart, to form the core (this process began when, now has not ended, have different opinions). Due to the heavy material to the concentration of released potential can make the earth's temperature is about 2000 DEG C. This promotes the chemical differentiation process, separated by mantle crust. Crustal rocks by weathering and erosion of air and water, the sedimentary and sedimentary rocks, the latter by the gas and solution discharged from the underground, the effect of temperature, pressure and metamorphism and the formation of metamorphic rocks.
这些岩石继续受到以上各种作用，可能经受过多次轮回的熔化和固结，先形成一个大陆的核心，以后增长成为大陆。原始地球不可能保持大气和海洋，它们都是次生的。海洋是地球内部增温和分异的结果，但大气形成的过程要更复杂。
These rocks continue to be above all, may be subjected to melting and consolidation of cycle times, to form the core of a continent, later to become the mainland growth. The original earth may not keep the atmosphere and oceans, they are secondary. The oceans are the result of a moderate increase in the earth's interior, but the process of the formation of the atmosphere is more complex.
原生的大气可能是还原性的。当绿色植物出现后，它们利用太阳辐射使水气（H2O）和CO2发生光合作用，产生了有机物和自由氧。当氧的产生多于消耗时，自由氧才慢慢积累起来，在漫长的地质年代中，便形成了主要由氮和氧所组成的大气。
The primordial atmosphere may be rective. When green plants appear, they use the sun's radiation to make water vapor (H2O) and CO2 photosynthesis, resulting in the proction of organic and free oxygen. When oxygen is proced more than consumption, the free oxygen is slowly accumulated, in the long geological time, it formed the main nitrogen and oxygen in the atmosphere.
