You should say: What it is. How this traffic method was invented. Where you see it, and then explain why you like it. I am gona introduce this traffic tool, it is a min shuttle bus. This kind of bus is newly designed by a group of bus creative scientists. They first hit upon this idea three years ago when traditional buses output no small amount of pollutant air caused by burning petrol. So, they wondered if it would be possible to invent a new one to replace it. Then one scientist discovered that if he put electricity onto the engine, which might achieve this initial proposal, and he then started to work on developing various kinds of battery, so he went to look at how go kart run its battery. Afterwards, he lent the idea of it and enlarged the storage amount of this sort of battery. Finally, he succeeded in inventing a new battery, after several experiments in use of being on double decker bus, it turned out that it would be more than awesome to lead the engine. Then he put it into shuttle buses. Accordingly, I would say this kind of bus does save energy, because cost on making up a piece of battery is far less than using petrol as a sort of ignition power. Therefore, ideally, more people would choose to use this shuttle buses. Besides, I would say, this invention is a breakthrough in history, why? If possible, other communication tools, like trucks, lorries, cabs could be also possible by adopting this sort battery as long as we create more stations to charge for it.
