Energy

As we all know we need energy in our daily life. There are many kinds of energy. We can get our energy from food.
The energy in food comes from sunlight which helps plants grow. Plants store up energy from the sun, much of our food comes from plants. Some of our food comes from animals, but animals depend on plants for food too.
标题：能源
内容：我们都知道，我们需要在我们的日常生活能源。有多种能源。我们可以从食物中获取的能源。
在食物中的能量来自阳光，帮助植物生长。植物储存来自太阳的能量，我们的食品从植物中来得多。我们的食物，有一些是从动物，但动物，植物食物过于依赖。

One of the main problems the world is facing today is the energy crisis. With the development of industry and agriculture, the world has consumed a great amount of energy. But all this energy has gone forever. Therefore, energy supplies are becoming short, in other words, all forms of energy willbe exhausted in future.

However, energy is of great importance to us. We can hardly imagine how we could live in a world without energy.We wouldn't be able to drive our cars and listen to our favourite music. Moreover, the night would become dark all the time. In short, once we lose all the energy resources, we will not be able to exist in the world.

Therefore, conserving our energy is an important task.We must take active measures to protect our energy resources.On the one hand, we should use our energy reasonably;on the other hand, we should instruct our people not to waste energy so that we will be able to send a good gift——energy, to our next generation.

Life needs positive energy. A person's life is a road with lots of difficulties and various negative emotions. Everyone will have the desperate time. Positive energy can help us go through this period of time. For example, I am sad about the exam yesterday. But an optimistic classmate encourages me to think in a good way and comfort me. I can recover soon. But if she also is as pessimistic as me, I won’t have recovered so quickly. Maybe I will be sad for a long time. There are many similar things happening in our life. To live a better life, we need positive energy.

生活需要正能量。人的一生是充满困难和各种负面情绪的一条路。每个人都有郁闷的时候。正能量可以帮助我们度过这段时期。例如，我为昨天考试的事而难过。但是一个乐观的同学鼓励我往好的方面想，安慰我。我可以很快地恢复过来。但是如果她也跟我一样悲观的话，我不可能这么快恢复心情的。也许我会伤心很久。在我们的生活中有很多这种类似的事情。为了生活得更美好，我们需要正能量。

Another round of energy crisis is knocking at the door. In 2004, world oil consumption reached a new record, causing oil price in the international market to skyrocket amazingly. As for China, it was reported that many traditional mineral cities in northeastern China had run into predicament, with their economy collapsed and workers unemployed, only because coal had been mined out.

Fossil energy resources, including coal, oil and gas, are unlike sunlight, water power and wind power which are generated consistently. They're not practically reproductive during human history. Once consumed, they're gone forever. If they were to be exhausted before we could find sufficient reproductive resources to replace them with, we'd have to live in entire blackout again like our ancestors have done thousands of years ago. That's of course not what anyone would want to see.

Due to technical limitations, people still have to utilize these resources now.

As a result, we must economize them most cleverly. New techniques should be developed and applied to reduce energy cost in industry and daily life. Alternative energy should be employed wherever possible. Eradicate any practice that wastes energy. Humans have overcome so many crises in history, and we're sure to win this time also.

新一轮的能源危机在敲响警钟。 2004年，世界石油消费量达到了一个新的纪录，能源危机导致国际市场上的石油价格扶摇直上，令人惊讶。至于中国，据报道，在中国东北的许多传统矿业城市运行陷入困境，他们经济崩溃并且工人失业，不仅是因为煤炭已经被开采完了。

化石能源资源，包括煤，石油和天然气，不像阳光，水，风电不断的产生。他们在人类的历史上几乎不会再产生了。一旦消耗殆尽，这些能源将永远不会再生。如果在他们被耗尽之前，我们还没有找到能够取代它们的资源，我们将不得不生活在一片黑暗之中，就像几千年前我们的祖先。这当然是任何人都不愿意看到的。

由于技术的限制，人们仍然必须利用这些资源。

因此，我们必须很巧妙的去节约资源。应该尽力开发和应用新技术，在工业和日常生活中降低能源成本。要尽可能的采用替代能源。消除任何浪费资源的行为。人类已经克服了这么多历史上的危机，这个时候我们也一定会取得成功。

A summary of the physical and chemical nature of life must begin, not on the Earth, but in the Sun; in fact, at the Sun's very center. It is here that is to be found the source of the energy that the Sun constantly pours out into space as light and heat. This energy is librated at the center of the Sun as billions upon billions of nuclei of hydrogen atoms collide with each other and fuse together to form nuclei of helium, and in doing so, release some of the energy that is stored in the nuclei of atoms. The output of light and heat of the Sun requires that some 600 million tons of hydrogen be converted into helium in the Sun every second. This the Sun has been doing for several thousands of millions of year.

The nuclear energy is released at the Sun's center as high-energy gamma radiation, a form of electromagnetic radiation like light and radio waves, only of very much shorter wavelength. This gamma radiation is absorbed by atoms inside the Sun to be reemitted at slightly longer wavelengths. This radiation , in its turn is absorbed and reemitted. As the energy filters through the layers of the solar interior, it passes through the X-ray part of the spectrum eventually becoming light. At this stage, it has reached what we call the solar surface, and can escape into space without being absorbed further by solar atoms. A very small fraction of the Sun's light and heat is emitted in such directions that after passing unhindered through interplanetary space, it hits the Earth.

在现实生活或工作学习中，大家都经常看到作文的身影吧，作文可分为小学作文、中学作文、大学作文（论文）。如何写一篇有思想、有文采的作文呢？以下是小编为大家整理的关于治理雾霾的英语作文Save Energy，仅供参考，欢迎大家阅读。

Water used to be mistaken to be an unlimited and renewable resource. Actually, water resource is very limited and precious. It is fortunate that now the public is starting to pay attention. Just as is depicted in the picture, just like saving money, the lovely and smiling piggy bank is collecting every drop of water falling from the water tap。

However, water shortage is still a serious problem threatening the existence and survival of the whole human being, and yet the phenomenon of wasting water can still easily be found anywhere in our daily life. For example, water taps are frequently left on by careless users. Someone even assumes that they have the right to waste water because they pay for it so that it has nothing to do with others. In fact, so precious is water that we cannot afford to waste it. Water resource is indispensable not only in our daily life but also in the industry and

agriculture. And water is the wealth of the whole mankind, and it is hard to imagine what the world would be like when there is no more water。

Even though an increasing number of people have become aware of this emergency, further measures still need to be taken. On the macro level, the whole world should make a joint effort to fight against waste of water. On the micro level, publicizing activities, such as broadcasting wonderful ways on how to save water on TV and other media, should be conducted. To store water means to store happiness and only by saving water can we save a better life for our offspring。

水被误认为是一种无限的可再生资源。事实上,水资源是非常有限的,宝贵的。幸运的是,现在公众开始关注。正如这幅画所描绘的,就像存钱一样,笑眯眯地可爱的.小猪银行收集的每一滴水的水龙头。

然而,水资源短缺仍然是一个严重的问题威胁着整个人类的生存和生存,然而,浪费水的现象仍然可以很容易地发现在我们的日常生活中。例如,经常有粗心大意者忘记关水龙头。更有甚者认为他们有权废水因为他们付钱,与他人无关。事实上,水是如此珍贵,我们不能浪费它。水资源不仅是必不可少的在我们的日常生活,也在这个行业

农业。和水是人类的财富,和很难想象世界会是什么样子当没有更多的水。

尽管越来越多的人已经意识到这种紧急情况,仍需采取进一步措施。在宏观层面上,全世界应该共同努力打击浪费水。在微观层面,宣传活动,如广播电视上美妙的方式如何节约用水和其他媒体,应该进行。储存用水就是存储幸福,只有节约用水才能拯救一个更好的生活为我们的后代。
