Many people write to newspapers and magazines to express their opinions. Letters to the editor must carry the writer’s full name, address and telephone number, although the information is not necessary for publication. This requirement to provide personal particulars is a clear indication that writers are responsible for what they say. When a writer wants his voice heard, he needs to claim ownership of his voice. Responsibility is the name of the game.
“People today prefer living together to putting their signatures on a marriage certificate because they refuse to accept responsibility for the relationship,” said social worker Ken Yip, “and this is what is causing a lot of family problems.” When we sign a paper, for example, a business contract or a bank document, the signature is a seal of consent, an agreement to take the matter seriously. Most governments and many organizations will not process written complaints if they do not bear the writer’s signature. The absence of a signature, they explain, tells us that the writer cannot be too serious and therefore does not deserve a reply.
There are people who wish to remain anonymous(匿名的) for various reasons. Multi-billionaire Mr. King donates generously to charity several times a year. He gives simply because he wants to help but not for the publicity his donations may bring, and he doesn’t want his good deeds to make news. In other cases, people insist on anonymity because they are afraid of the consequences of revealing their identity. Crime witnesses may be willing to assist the police, but most are unwilling to give their names when reporting a crime.
Name or no name? The answer is very personal and lies in how much we want to get involved. We all have a name. It is a matter of responsibility to use it when we make a statement, a claim or an accusation. We all want to honor our own name, and it is only by stamping our expression of an opinion with our name that we honor what we say.
【小题1】What does the writer mean by saying “Responsibility is the name of the game”?

【小题3】Some people don’t want their names known because they are_______.
【小题4】The passage is mainly about_____.

Violin prodigies (神童), I learned, have come in distinct waves from distinct regions. Most of the great performers of the late 19th and early 20th centuries were born and brought up in Russia and Eastern Europe. I asked Isaac Stern, one of the world’s greatest violinists the reason for this phenomenon. “It is very clear,” he told me. “They were all Jews and Jews at the time were severely oppressed and ill-treated in that part of the world. They were not allowed into the professional fields, but they were allowed to achieve excellence on a concert stage.” As a result, every Jewish parent’s dream was to have a child in the music school because it was a passport to the West.
Another element in the emergence of prodigies, I found, is a society that values excellence in a certain field to nurture (培育) talent. Nowadays, the most nurturing societies seem to be in the Far East. “In Japan, a most competitive society, with stronger discipline than ours,” says Isaac Stern, children are ready to test their limits every day in many fields, including music. When Western music came to Japan after World War II, that music not only became part of their daily lives, but it became a discipline as well. The Koreans and Chinese as we know, are just as highly motivated as the Japanese.
That’s a good thing, because even prodigies must work hard. Next to hard work, biological inheritance（遗传） plays an important role in the making of a prodigy. J. S. Bach, for example, was the top of several generations of musicians, and four of his sons had significant careers in music.
