（钟文润 福建省福州华伦中学）
Hello, everybody! Recently I have invented an amazing product called electronic suit with my imagination. Maybe it sounds strange, but I believe
you will change your mind after listening to my introduction.
First of all, the suit is made of nano-materials, so there's no need to worry about being dirty easily.
范文赏析
开门见山，直入主题。过去分词做后置定语修饰product，表达高级
Besides, I put some tiny high-tech products into it in order to control the temperature. With the help of computers, the suit can change its temperature itself. What's more, being very hard-wearing, the suit can help you save money. Last but not least, the suit has lots of colors, so you can choose your favorite color and it will look nice on you.
There is no doubt that it will be your best choice if you want to buy a new suit. So don’t hesitate, just try it!
