關於能源的問題成為了近年來大家關心的熱點問題。很多不可再生能源需要大家去保護，節約。為了幫大家理清寫這類作文的思路，我們來看一篇範文：
Ever since early this century, electricity has become an essential part of our modern life. It plays an important role in many fields such as industry, agriculture and the daily life of men. Electricity is a source of energy that makes it possible for the factories to turn out products and for people to create comfortable living conditions, for example.
If there were no electric power, things would be quite different. Machines could not run and people would have to fall back on their hands to produce what is essential for them to keep alive. Traffic would have to stop at night because there would be no lights in the street. A world in darkness would no longer be a pleasant one. In a word, things would be in a mess.
Therefore, we should realize the importance of electricity. As electricity is insufficient in our country, we should be frugal in using electricity. We should make great efforts to produce more electricity.
這篇範文講的是電。典型的三段論
1. How can we use electricity?
2. What would happen if there were no electricity?
3. We should improve the enery conservation.(節約能源)
從上文中可以看出，有很多關於能源的`詞彙是我們必須掌握的。
對於這來話題，我們要從一下幾方面入手：
1. 此能源用來幹什麼，也就是回答What can we do by using it?
2. 沒有這類能源，世界或者我們的生活會是什麼樣，也就是回答What would happen if there were no...?
3. 怎樣合理利用能源，也就是回答What should we do to improve the enery conservation?
