W: Today, in our studio, we are talking about child-rearing, and we have Dr. Smith here. He is a famous expert in this field, and he has been a teacher for many years. Hello, Dr. Smith, welcome.
M: Hello, I’m glad to be here to talk about this topic, and I’m ready to answer questions.
W: OK, Dr. Smith. American parents seem to give children allowance each week, for example, $10 a week. What do you think of it?
M: Well, on the one hand, children may learn to budget their money through the allowance given by parents, but on the other hand, they may not understand the idea of "No pains, no gains."
W: Do you have a better way for parents?
M: In fact, it might be a better way if children earn money for themselves than from their parents. I mean, for example, if the children clean their rooms every day, they may get one dollar from their parents. By doing this, the children will have a better understanding of the value of money.
W: Well, Dr. Smith, you know, nowadays, computers are popular among every family. What’s the influence of the Internet on children in your opinion?
M: You know, every coin has two sides. We get many conveniences from surfing the Internet, but for children, things may be different. You see, in most cases, children play computer games instead of searching for the information they need. And in the worst cases, children may be addicted to games so much that they can’t concentrate on what they should do.
W: Thank you, Dr. Smith. We take a rest first and then answer questions from our listeners.
M: OK.
