Since the 1970s, with the worsening oil crisis, the major businesses in the automotive internal combustion engine as much as possible to reduce the car's fuel consumption, while sparing no effort in the development of hybrid vehicles and new energy vehicles. There are hybrid gas-electric hybrid and mixed fuel in two forms, both in the car body design is no different with the traditional internal combustion engine vehicles, the future trend is nothing more than a continuation of current trends, efforts to reduce the drag coefficient, reducing weight while increasing strength and stiffness and so on.
Hybrid vehicle technology only in the product over, to really new energy vehicles, preparatory and experimental products, the ultimate trend or completely replace the existing traditional energy vehicles by the new energy vehicles.
What appearance is prospective car?You do not know!That le,it is like train of magnetism in suspension in sky travel.There is a guide in the car -- satellitic navigation system.The glass of the car can prevent ultraviolet ray,make the person\'s eye is not harmed.The car is to rely on to compress the reactive force that air releases to fill the car,rely on another compression again air is in a rear eduction,the car runs quickly to ahead like jet aircraft.Car rate of future is very rapid,one hour can run hundreds of kilometers,even thousands of kilometer.You let it open way of how many kilometer,want to say to the car only,the car can bade by yours go doing.Prospective car has a lot of advanced places:There is same thing in the car,can control the steering wheel of the car.

City traffic is a big problem in some cities in the world, especially in big cities. To solve the problem, someone are in favor of developing buses as means of city traffic. Others are in favor of the subway. Between them,which is the better choice?
在世界上的一些城市中城市交通是一个大问题,尤其是大城市。为了解决这个问题,有人赞成发展公交车作为城市交通的方式。另一些人则赞成地铁。在它们之间,哪个是更好的`选择?
It is easier to take buses as means of city traffic than the subway trains because buses don't need special roads. But buses have also many disadvantages, some of which are very serious. They may cause louder noise and more traffic accidents. Buses give rise to serious air pollution and traffic jam. In order to stop what buses cause, a large amount of hand must be used to widen the roads. On the contrary, the subway train is of more advantages. Except the difficulty and high cost of building the subway, it is superior to the buses in many aspects.
公共汽车作为城市交通方式要比地铁容易,因为公共汽车不需要特别的道路。但是公交车也许多缺点,有些是非常严重的。他们可能会导致噪音和更多的交通事故。公共汽车也导致了严重的空气污染和交通堵塞。为了阻止公交车带来的后果,必须用大量的人力来拓宽道路。相反,地铁列车有着更多的优势。除了建设地铁的难度和高成本外,在许多方面它都优于公共汽车。
Taking the advantages and disadvantages together into consideration,I would be in favor of developing the subway train as soon as possible.
把优点和缺点一起考虑,我会赞成尽快发展地铁。
