听力原文:W: Morning, Mr. Park.M: Come here, Miss Li, I have something to talk to you.W: Wh

听力原文:W: Morning, Mr. Park.

M: Come here, Miss Li, I have something to talk to you.

W: What's the problem, Mr. Park?

M: We need to define a new strategy which must be flexible enough to take account of changing market conditions.

W: I agree. Our main objective must be to gain market share, and to do this we must reduce prices.

M: So you are sure that if we reduce prices, our market share will increase?

W: Yes, I'm sure.

M: That might be true. But if we reduce our prices, our margins will be lower and that will cut our profits.

W: In short term it is right. But we can slowly increase our production and as the production is increased, we may cut unit cost.

M: That's really a log-term prospect. But I believe higher profitability is our objective. The better the products, the higher the price, and the higher price will enhance higher profits.

W: The market is already very competitive. And if we raise our prices, whatever the quality, sales will drop rapidly.

M: Then shall we look at it from the other viewpoint--manufacturing. Well, if we can reduce cost in manufacturing that must put us in a strong position to adapt to the market. The only way for us is to sub-contract more of the production.

W: That will mean job losses if we do that.

M: That's true. But the jobs that remain will be more secure.

W: It sounds reasonable. Maybe we can try this way.

M: That's the best we can do, don't you agree?

(23)

A.Market share

B.Company strategy

C.High profitability

D.Manufacturing

听力原文:M: Hello. Would you please tell me something about the stock?W: Sure. What do you

听力原文:M: Hello. Would you please tell me something about the stock?

W: Sure. What do you want me to start with?

M: Please start with the explanation of some terms like "a bull" and "a bear".

W: OK. A bull is a situation in which share prices are rising.

M: What about a bear then?

W: A bear is the situation in which share prices keep falling.

M: Oh, I see. But why the prices get rising or falling?

W: If there are more buyers, the price will rise. Otherwise, the price will be lower and lower.

M: How can we make money in the stock market?

W: If you believe the market will go up, you can buy in or hang on. If it turns out to be true, you can make your profit.

M: I heard that some people can earn money out of a bear market. How do they win in such a situation?

W: lf you believe the market will fall down, you can sell your shares and buy back at a lower price. The price difference is your profit.

M: It sounds easy to make money from stock investment.

W: Not at all. When you really invest in stock market, you'll get involved into the whole world.

M: What do you mean by that?

W: To decide which share you'll buy in is quite hard sometimes. You have to consider the market tendency, the growth of the company and you'd better know something about technical analysis.

M: So boring it is. I'd better invest in some fixed interest fields.

W: Certainly you can. You won't suffer from the risks. But your wallet will suffer.

M: What should I do?

W: If you really invest in stock, perhaps you should find a broker.

(20)

A.He is a stranger to the stock.

B.He likes the stock very much.

C.He is confident of his investment.

D.He is the student of the woman.

听力原文:W: Everybody is talking about genes today, but do genes determine everything abou
t us?

M: (23) Genes and environment work together to shape who we are. As the environment includes everything we experience and come into contact with from birth through to death, it also plays an extremely complex role.

W: What is gene, then?

M: Even scientists disagree on exactly how to define a gene. Generally, a gene is a sequence of DNA that tells us what a single protein does. Proteins do the work of the body, building structure and stimulating biochemical reactions.

W: (24)How genetically similar are we to one another?

M: Individual humans are extremely similar to each other. They share 99.9 percent of their DNA no matter which race they belong to.

W: How genetically similar are we to other species?

M: Scientists have been amazed at how genetically similar humans are to other species. Humans share 80 percent of their genes with mice, about 99 percent of DNA with chimpanzees. That means that chimpanzees are more closely related to humans than to other animals, such as monkeys, whales or cats.

W: (25)Will genes lead to a cure for cancer and other serious disease?

M: Of course! Virtually every disease has genetic cause. Some are simple misspellings that can be corrected with gene therapy, although this technology is still in its infancy. Scientists will gain more knowledge about genes, and they will develop new treatments based on that knowledge. The outlook is especially good over the next few decades for some cancers and other disease.

(20)

A.Environment and genes.

B.Cells of proteins.

C.Genes of parents.

D.A sequence of DNA

听力原文:W: It was just five years ago that the iPod first hit the market. Now wherever yo
u go, you are sure to see those white ear buzzes. Steve, did Apple understand what it was launching five years ago?

M: Not really, it was after iPod came out that they realized everyone could enjoy this. Then they decided to extend it to the Windows platform, and millions of people took off with iPods.

W: What exactly has it brought?

M: It changed Apple from a company with a small market share with millions of computers to one with a massive market share in an incredibly important new product category.

W: Then iPod has completely changed Apple's profile.

M: Right. People are now being driven from iPods to Apple's computers as opposed to vice versa. They say, "This iPod is amazing. My whole music collections are with me. It's so easy to use. I love it. "And they look at Apple's software as well.

W: How many are being sold?

M: 67 million. It's going to be 70 million pretty soon. I think next year it will hit 100 million.

W: That's incredible. Do you think it is the peak or will it keep moving?

M: Keep moving. Take a look at the first iPods, they were sort of huge. They are getting smaller, and this year we've got even smaller.

W: I guess that's the other thing about iPods. They are amazing, good in your hands, so user-friendly. They're really imaginative.

M: Yeah, the more you use it, the more you become emotionally attached to it. You know what's really changed? I don't think Apple wants to do this. The music business world. On the iTune store, you can pick any song you like and buy it anytime you like.

(23)

A.How iPod has changed Apple computers.

B.The impact iPod has had on the world.

C.The advantages of possessing an iPod.

D.The popularity of iPod among people.
