W: Ok, last night you were supposed to read an article about human bones. Are there any comments

about it?

C {@
M: well, to begin with, I was surprised to find out there were so much going on in bones. I always
s l-B!J5F v`:@
assumed they were pretty lifeless.
/` i"Hi,f
W: Well, that’s an assumption many people make. But the fact is bones are made of dynamic living r] Vi#R

tissue that requires continuous maintenance and repair.
c%MeX hf|
K
M: Right That’s one of the things I found so fascinating about the article the way the bones repair themselves.FA#D`{6d
K:lp
W: Ok. So can you tell us how the bones repair themselves.
Ur x!a"a
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 produces 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 they produce the new tissue that fills in the hole that was made by the first group. D(N,Jy&W"Y3S
W: Very good. This is a very complex process. In fact, scientists who study human bones don’t CKK1{o9J
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.T#e
V;F
uO
M: ok, I get it. So if the scientists can figure out what makes the specialized cells work, maybe they &k,T*{ _)N.r(V\
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 ever occurring.Qw:Tl.t

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 all use public transportation when we could.

M: I’m sure you are right. Through a diesel bus isn’t exactly pollution free.

W: True. But they’ll be running a lot cleaner soon. We were just talking about that in my environmental engineering class.
K no3};T uh
M: What iss the city going to do? Install pollution filters of some sort in all their buses?8u[Q"A$?{"g
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 the engines more efficient.
7Y A.KHma
M: How?

W: Well, there is a material called conium oxide. It’s a really good insulator. And a thin coat of it gets sprayed on the certain part of the engine.
A9TkUu*b \ cg
M: An insulator?
iU o,C/A2x
W: 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.
W nPsZc
S G
M: So a lot less unburned fuel comes out to pollute the air, right？.
jG^lS3C
W: Yeah, and the bus will need less fuel. So with the savings on fuel cost, they say this will all pay for itself in just six months.
P Cj W5H%Q&^
M: Sounds like people should all go out and get some this stuff to spray their car engines.:c;s!` h Z @#D;v
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.I h,F ~/]{3[ m.k

Good evenings, ladies and gentleman, my name is Ellis Brown. As you know we hold a series of events during the school year on various cultural topics, I am happy there is such a large crowd of both students and professors at this, the second of our time out pretty art presentations this year. I think almost every seat is taken. Tonight we’re lucky to have as our guest, a man of considerable fame in the world of music. He began to play the piano at age 5. By the time he was 10, he was already composing and playing his own pieces. He is a graduate of a famous art school in New York City. Our guest has spent the last 45 years of his very successful career touring the world playing concert. We are fortunate that he consented to come and share some of his experiences with us. He has had many adventures along the way. Locked instruments, missed connections, no hotel room, locked concert hall and so on. He has played for all of the most well-known conductors, not only in north America, but all over the world. The title of his talk is the concert tour- forty years on four continents. Please join me and welcome Mr. Daniel Robertson, one of the foremost pianist 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’s 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 a place where the demand for a product is greater than the supply, there’s no need to advertise. Now the earliest forms of advertising going back many hundreds of years with a simple sign over shop doors that told you whether the shop was a bakery, a butcher shop or what have you. Then with the advent of the printing, advertising increased substantially. As for product like coffee, tea and chocolate appeared in newspapers and other periodicals, as well as on the sides of building. In the American colonies, advertising and communication media like newspapers and pamphlets became a major factor in marketing goods and services. By modern standard, these early advertisements were quite small and subdued, not as splashy, whole page spread of today. Still some of them appeared on the front pages of newspapers probably because the news often consisted of less refresh reports from distant Europe while the news were current and local. Advertising really came and do it so and became an essential part of doing business during the industrial revolution. Suddenly there was a much greater supply of things to sell. And as we said earlier, that is the driving force behind advertising. People’s attention had to be drawn to the new product. Let’s take a look at some of the advertisements from that time.h d(z0t6E Bdk

We know then that in the United States it’s the job of congress to review proposed new laws which we call bills, and perhaps to modify these bills and then vote on them. But even if the bill passes in congress it still doesn’t become a law until the president had a chance to review it too. And if it’s not to the president liking, the bill can be vetoed or killed in either of two ways. One is by a veto message. The president has ten days to veto the bill by returning it to congress along with a message explaining why it’s being rejected. This keeps the bill from becoming a law unless overwhelming majorities of both houses of congress vote to override the president’s veto, something they rarely do. Often law makers simply revise the vetoed bill and pass it again. This time in a form that the president less likely to objective and thus less likely to want to veto. The other way the president can kill a bill is by pocket veto. Here is what happens. If the president doesn’t sign the bill within ten days and congress drew in during that time, then the bill will not become law. Notice that it’s only at the end of an entire session of congress that the pocket veto can be used, not just whenever congress takes the shorter break, say for a summer vacation. After a pocket veto, that particular bill is dead. If the law makers in congress want to push the matter in their next session, they will have to start all over with a brand-new version the bill.
