能量-Energy
Energy
Energy makes the world go, It is indispensible to both animal life and human life. We get heat energy from the food we eat, light energy from the sun and electricity from water. In the hot summer when there ia a power outage we feel all the more the need for electric energy which powers the electric fan md air-conditioner.
There are different sources of energy. The rivers and streams are a good source for electrie energy. The san provides us with light, heat and electricity. There is also sound energy in the radio transformed from electric energy. The energy can be changed from one form to another. It can never be exhausted nor reproduced. It just goes on changing in cycles.
It is important for us to make use of energy. Solar energy is being made to generate electricity, to cook and to bathe. Atomic energy is used in industry and aviation and many other fields. We are now doing our best to inake energy serve our people in every way possible. 中小學(xué)生語(yǔ)文題庫(kù)，中小學(xué)學(xué)生語(yǔ)文試卷，就來(lái)<A http://www.zequeka.cn/yuweNtiku/>易優(yōu)語(yǔ)文題庫(kù)</a>。
能
能量使世界運(yùn)轉(zhuǎn)。動(dòng)物和植物的生命都離不開能量。我們從所吃的食物中獲取熱能，從太陽(yáng)和水力發(fā)電中獲取光能。在炎熱的夏天，當(dāng)斷電時(shí)，我們更感需要能驅(qū)動(dòng)電風(fēng)扇和空調(diào)器的電能。
有不同的能源：江河溪流是電的良好能源；大陽(yáng)可提供光能，熱能和電能。在無(wú)線電傳輸中，電能可轉(zhuǎn)換為聲能。能量可以從一種形式轉(zhuǎn)接到另一種形式，它不會(huì)耗盡也不會(huì)創(chuàng)生，而是不斷地循環(huán)往復(fù)。
對(duì)我們來(lái)說(shuō)，充分利用能量很重要。人們正在利用大陽(yáng)能發(fā)電、做飯、洗浴。原子能被用于工業(yè)、航空和其他領(lǐng)域。我們正在盡一切可能讓能源服務(wù)于人類
