Clean air is all around us. People dont have to worry about polluting the air every time they drive their cars. They no longer need to face the problem of not having enough fuel either.Although scientists have been trying for many years to develop a new kind of car that does not need gasoline(汽油), they have been unsuccessful. Recently, however, car engineers have succeeded in creating a new kind of car that runs on gasoline and electricity. This is the famous “hybrid car”. This car gets its name from the fact that it has a gasoline engine(引擎) and an electric motor inside. Hybrid cars do not pollute the environment as much as the cars that are commonly used today. They also cost drivers less money because they need less fuel than ordinary cars.Hybrid cars are becoming widely popular in the United States. They are soon expected to become widely used around the world. If scientists and engineers continue to work on car development, perhaps the world with clean air that we imagined earlier just might become real in the future.()1.The underlined word “they” in Paragraph 2 means _A. cars Bdrivers Cengines Dscientists()2.Hybrid cars _A. increase air pollution Brun only on electricityChave no engines inside Dneed less fuel than ordinary cars()3.The passage tells us that with the development of cars, we may _A. like electric cars Bdrive cars easilyClive in the world with clean air Dunderstand how hybrid cars work()4.The best title for the passage would be _A.
