With the development of our society, energy in the world becomes more and more limited, so it is quite important for us to save energy and to protect our environment. As a student, there are a lot of methods we can do to save energy at home. For example, first, we can turn off the light as well as other appliances when we are not using them. Second, recycle the waste water, paper and other waste so that we can reuse them. What's more, it is suggested to use public transportation more instead of private cars.

　　随着社会的发展，在世界能源变得越来越有限，所以我们要节约能源和保护我们的环境是非常重要的。作为一个学生，有很多方法可以做在家里节省能源。例如，第一，我们可以关掉灯和其他的家用电器，当我们不使用它们。第二，回收废水，纸张和其他废物，我们可以重复使用。更重要的是，建议使用公共交通，而不是私家车。

　　Above all, everyone can make a great contribution to our environment. I hope I can learn more to develop new and clear energy, like energy from the wind and solar.

　　首先，每个人都可以使我们的环境的一大贡献。我希望我能学习更多的开发新的清洁能源，就像来自风能和太阳能。
