Bài làm của mình  đây ạ !

           Energy is one of the most important things in our life. We can not live withour energy, so we should save energy right now. Firstly , turn off all the electric appliances when we go out and use them economically. Secondly, we should use public transport or go to school on foot instead of going by motorbike or car. When we do that , we also keep the environment clean. Finaly , we had better take a shower to reduce the water we use. Because having a bath wastes water twice as much as using a shower. In short , energy plays an essential role in our life, when we save energy , it means we protect our life.
