CET6六级级作文范文：Energy Crisis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 will be 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.
