　　Conversation two

　　W: Hello, Gary. How’re you?

　　M: Fine! And you?

　　W: Can’t complain. Did you have time to look at my proposal?

　　M: No, not really. Can we go over it now?

　　W: Sure. I’ve been trying to come up with some new production and advertising strategies. First of all, if we want to stay competitive, we need to modernize our factory. New equipment should’ve been installed long ago.

　　M: How much will that cost?

　　W: We have several options ranging from one hundred thousand dollars all the way up to half a million.

　　M: OK. We’ll have to discuss these costs with finance.

　　W: We should also consider human resources. I’ve been talking to personnel as well as our staff at the factory.

　　M: And what’s the picture?

　　W: We’ll probably have to hire a couple of engineers to help us modernize the factory.

　　M: What about advertising?

　　W: Marketing has some interesting ideas for television commercials.

　　M: TV? Isn’t that a bit too expensive for us? What’s wrong with advertising in the papers, as usual?

　　W: Quite frankly, it’s just not enough anymore. We need to be more aggressive in order to keep ahead of our competitors.

　　M: Will we be able to afford all this?

　　W: I’ll look into it, but I think higher costs will be justified. These investments will result in higher profits for our company.

　　M: We’ll have to look at the figures more closely. Have finance draw up a budget for these investments.

　　W: All right. I’ll see to it.

　　Passage one

　　Next time you bring your kids in for a checkup, don't be surprised if the doctor asks about their tastes in entertainment. The American Academy of Medicine suggested last week that doctors work with parents to evaluate how much TV kids watch and what they see, what video and computer games they play, which websites they visit on the Internet, whether they view R-rated videos without the company of their parents, what music they like and what books they read. Doctors are worried that kids who spend too much time in front of the tube don't get enough exercise and can become overweight. The academy is also concerned that the messages kids get from entertainment media can make them more violent and sexually active.

　　The academy recommends that children under age two not watch any TV. "Children need activities to stimulate the brain during the first two years of life," says Dr. Miriam Baron, who chairs the academy's committee on public education. "They need feedback and socialization." Older children, she says, should watch TV in a common area. Their bedrooms should be "electronic media-free" zones where they can have a quiet place to read, study, play or just relax.
