A kind of little cars may some day take the place of today’s cars. If everyone drives such cars in the future,there will be less pollution from the cars. There will also be more space for parking cars in cities,and the streets will be less crowded. Three such cars can park in the space now needed for one car of the usual size.
The little cars will cost much less to own and to drive. Driving will be safer,too,as these little cars can go only 65 kilometers an hour. The cars of the future will be fine for getting around a city,but they will not be useful for long trips. Little cars will go 450 kilometers before needing to stop for more gas(汽油).
If big cars are still used along with the small ones,two sets of roads will be needed in the future. Some roads will be used for the big,quick cars and other roads will be needed for the slower,smaller ones.

Antifreeze is a liquid(液体) that is added to water to keep it from freezing. When water freezes and turns to ice,it expands(膨胀).The force of water expanding is so great that it will break the hardest metal.Water is used in car engines(发动机) to keep them cool while they run,and if this water is allowed to freeze in winter it can break the iron block of the engine.That is why antifreeze is necessary.
Water freezes at 0℃;the usual kind of antifreeze will not freeze until the temperature is-40℃.A mixture(混合物) of five parts of water and four parts of antifreeze will prevent freezing at-18℃;four parts of water and five parts of antifreeze reduce this to -22℃.
Alcohol is a kind of good antifreeze,but when the air is running it becomes hot and the alcohol boils away,so it must be changed very often.Most people use antifreeze that does not boil away when the engine is running.There are several chemicals that do this.One of the most popular is called ethylene glycol.
