Old Cremona Violins
Most musicians(音乐家) agree that the best violins(小提琴) were first made in Cremona, Italy, about 200 years ago. These violins sound better than any others. They even sound better than violins made today. Violin makers and scientists try to make instruments(乐器) like the Italian violins. But they aren’t the same. Musicians still prefer the old ones.
Some people think it is the age of the violins. But not all old violins sound wonderful. Only the old violins from Cremona are special(特殊的). So age cannot be the answer.
Other people think the secret to those violins is the wood. The wood must be from certain kinds of trees.
But the kind of wood may not be so important. It may be more important to cut the wood in a special way. Wood for a violin must be cut very carefully. It has to be the right size and shape(形状). The smallest difference will change the sound of the violin. Musicians sometimes think that this was the secret of the Italians. Maybe they understood more than we do about how to cut the wood.
Size and shape may not be the answer, either. Scientists can make new ones that are exactly the same size and shape. But the new violins still do not sound as good as the old ones. Some scientists think the secret may be the varnish. Varnish is what covers the wood of the violin. It makes the wood look shiny. It also helps the sound of the instrument. But no one knows what the Italian violin makers used in their varnish.

You may have heard of the famous saying, "East or West, home is the best. "
What does the word "home" mean to you? How do you say the word in French? In Chinese? In your language? Although people usually know what the word means, it sometimes has no exact translation. It's not surprising, because the idea of home is "different from country to country, and from person to person. A home is more than a roof and four walls. It's the cooking, eating, talking, playing and sleeping that go on inside. And at home you usually feel safe and relaxed.
Homes look different in different countries. They also have different things inside. For example, in cold northern Europe, there's a fire in the living room or kitchen and all the chairs face it. In the south, where the sun shines a lot and it's more important to keep the heat out, there are small windows and cool stone floors.
