Passage  

Most musicians agree that the best violins were first made in Gremona, 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 from Gremona are special. So age cannot be the answer.The 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. 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(漆). Varnish is what covers the wood of the violin. It makes the wood shiny. It also helps the sound of the instrument. But no one knows what the Italian makers used in their varnish.

Passage 

One day, I happened to find a wallet. I picked it up and opened it to see if I could find out the owner's name. There was nothing inside it except some change and an old photograph——a picture of a woman. I put the photograph back and took the wallet to the police station.That evening I went to have dinner with my aunt and uncle. They also invited a young woman so that there would be four people at the table. Her face was familiar. I was quite sure that we had not met before, but I could not remember where I had seen her. While talking, however, the young woman happened to mention that she had lost her wallet that afternoon. All at once I realized where I had seen her. She was the woman in the photograph, although she was now much older. She was very surprised, of course, when I was able to describe her wallet to her. Then I explained that I had recognized her from the photograph I had found in the wallet. My uncle insisted on going to the police station immediately to get the wallet. As the policeman handed it over, he said that it was amazing that I had not only found the wallet, but also the person who had lost it.

Maybe it seems like everybody else already has their friends.But remember, there's always room for more friends. Start by looking around your classroom—think about which kids you'd like to play with at break.Look for chances to say hi to them，smile，and be friendly.Offer to share something or express your appreciation(欣赏)to them.Invite someone to play with you or say 《Do you want to sit here?》 in the lunchroom.When you're at break，walk over to kids you want to play with.act friendly，and say 《Hi，can l play, too?》 or just join in. If you have trouble doing this or if you're feeling shy, ask your teacher to help you make new friends.Teachers are usually pretty good at matching up friends.The best way to make friends is to be a friend.Be kind，be friendly，share，say nice things，offer to help—and pretty soon，you'll have one，or two，or even more new friends. You might still miss that special best friend.But when you see each other, you can share something you didn't have before she left：You can introduce her to your new friends!
