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.
　　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.

　　随着我们社会的发展,能源在世界上变得越来越有限,所以对我们来说是相当重要的节约能源和保护我们的环境。作为一名学生,我们可以有很多方法来节约能源。例如,首先,我们可以关灯及其他电器当我们不使用它们。第二,回收废水、纸张和其他浪费,这样我们可以重用它们。更重要的是,建议使用公共交通而不是私家车。
　　最重要的是,每个人都能对我们的环境做出了巨大的贡献。我希望我能学习更多开发新和清晰的能源,如风能和太阳能。
