Imagine a world where air pollution is no longer a problem. Clean air is all around us. People don't 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 , _ 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 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. The best title for the passage would be _ . A) The Car of the Future B) The Meaning of Hybrid C) The Use of Hybrid Cars D) The Invention of the Car

If you do not use your arms or your legs for some time, they will become weak, and when you start using them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that memory works in the same way. When someone says that he has a good memory, he really means that he keeps his memory in practice by using it. When someone else says that his memory is poor, he really means that he does not give it enough chance to become strong. If a friend says that his arms and legs are weak, we know that it is his own fault. But if he tells us that he has a poor memory, many of us think that his parents may be blamed, and few of us know that it is just his own fault . Have you ever found that some people can't read or write but usually they have better memories? This is because they cannot read or write and when they have to remember things, they cannot write them down in a small notebook. As a result, they have to remember days, names, songs and stories, so their memory is being exercised the whole time. So if you want to have a good memory, learn from the people: practice remembering things in a way as other people do. Which of the following statements is true? A) Your memory needs chance for practice. B) A good memory is inherited from parents. C) Your memory works in the different ways as your arms or legs. D) Don't learn to read and write if you want to have a good memory.
