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.
The source of Energy
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.
能源危机(Energy Crisis)
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.
