31-34

W: ok, last night you were supposed to read an article about human bones Are there any comments about it?

M: well, to begin with, I was surprised to find out there were so much going on in bones I always

assumed they were pretty lifeless

W: Well, that's an assumption many people make But the fact is bones are made of dynamic living tissue that requires continuous maintenance and repair

M: Right That's one of the things I found so fascinating about the article the way the bones repair themselves

W: Ok So can you tell us how the bones repair themselves

M: Sure See, there are two groups of different types of specialized cells in the bone that work together to

do it The first group goes to an area of the bone that needs repair This group of cells produce the chemical that actually breaks down the bone tissue, and leaves a hole in it After that the second group of specialized cells comes and produce the new tissue that fills in the hole that was made by the first group W: Very good This is a very complex process In fact, the scientists who study human bones don't completely understand it yet They are still trying to find out how it all actually works Specifically, because sometimes after the first group of cells leaves a hole in the bone tissue, for some reason, the second group doesn't completely fill in the hole And this can cause real problems It can actually lead to

a disease in which the bone becomes weak and is easily broken

M: ok, I get it So if the scientists can figure out what makes the specialized cells work, maybe they can find a way to make sure the second group of cells completely fills the hole in the bone tissue every time That'll prevent the disease from every occurring

M: Hi Diana, mind if I sit down?

W: Not at all, Jerry How have you been?

M: Good But I'm surprised to see you on the city bus Your car in the shop?

W: No I've just been thinking a lot about the environment lately So I decided the air will be a lot cleaner if

we call use public transportation when we could

M: I'm sure you are right The diesel bus isn't exactly pollution free

W: True They'll be running a lot cleaner soon We were just talking about that in my environmental engineering class

M: What could the city do? Install pollution filters in all their buses?

W: They could, but those filters make the engines work harder and really cut down on the fuel efficiency Instead they found a way to make their engines more efficient

M: How?

W: Well, there is a material called XXX It's a really good insulator And a think coat of it get sprayed on the certain part of the engine

M: An insulator?

W: Yeah What it does is reflect back the heat of burning fuel So the fuel will burn much hotter and burn

up more completely

M: So a lot less unburning fuel comes out to pollute the air

W: And the bus will need less fuel So with the saving on fuel cost, they say this will all pay for itself in just six months

M: Sounds like people should all go out and get some this stuff to spray their car engines

W: Well, it's not really that easy You see, normally, the materials are fine powder To melt it so you can spray a coat of it on the engine parts, you first have to heat it over 10,000 degrees and then, well, you get the idea It's not something you or I be able to do ourselves

M: What's the city gonna do? Install pollution filters of some sort on their buses?

W: They could, but those filters make the engines work harder and really cut down on fuel efficiency Instead they found a way to make their engines more efficient

M: How?

W: Well, there is a material called the coniine oxide It's a really good insulator And a thick coat of it get sprayed on the certain part of the engine

M: An insulator?

W: Well, yeah Actually, what it does is reflect back the heat of burning fuel So the fuel will burn much hotter and burn up more completely

M: So a lot less unburned fuel comes out to pollute the air, right?

so on He's played for all of the well-known conductors, not only in North America but all over the world The title of his talk is the country tour 40 years on 4 continents Please join me in welcoming Mr Daniel Robinson, one of the foremost pianists of our day

Let's turn our focus now to advertising We all know what an advertisement is, it's essentially a message that announces something for sale Now, there is an important precondition that must exist before you have advertising, and that's a large supply of consumer goods, that is, things to sell You see,

in the place with a demand for a product is greater than the supply, there's no need to advertise Now, the early form of advertising going back many hundreds of years with a simple sign there were shop doors that told you whether the shop was a bakery, a butcher shop or what have you, then was the advent of the printing crest Advertising increased substantially as for products like coffee, tea, and chocolate appeared in newspapers and another periodicals as well as on the side of the buildings In the American
