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. Therefore energy supplies are becoming short.

However energy is of great importance to us. We can hardly imagine how we could live in a world without energy.In short once we lose all the energy resources we will not be able to exist in the world.

Thereforewe 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.

一个主要的问题是当今世界面临的能源危机。随着工农业的发展世界已经消耗了大量的能量。因此能源供应越来越短。

然而能源对我们是非常重要的。我们几乎不能想象没有能源我们可以生活在这样一个世界。简而言之一旦我们失去所有的能源我们将无法在世界上存在。

因此我们必须采取积极的措施来保护我们的能源资源。一方面我们应该使用能源合理;另一方面我们应该教导人们不要浪费能源。
