听力原文: Web filtering is just one method or restricting access to the Internet. Here are some countries that have tried to control or track their residents' online activities, according to Reporters Without Borders.
Saudi Arabia—The government filters all traffic through a central server and recently issued regulations banning access to sites considered subversive, contrary to the State or its system or damaging to the dignity of the heads of state.
Burma—Except for some government officials and businessmen, few people in this military-controlled country have access to the Internet. A colonel was jailed after visiting an opposition political site.
China—Internet service providers must install filters that block the Web sites of many Western media outlets, Taiwan and Hong Kong newspapers, human rights groups and the Falun Gong, the banned illegal movement. The government has set up a special Internet police unit.
Britain—Last year the Regulation of Investigatory Powers Act extended police phone-tapping privileges to the Internet. If asked, companies and individuals would have to help law enforcement officials decode lawfully obtained data.
Russia—The government has instituted an Internet surveillance system that requires service providers and telephone operators to reroute data traffic to local law enforcement headquarters, allowing authorities to monitor phone calls or e-mail.
Australia—The government does not filter the Internet, but the Broadcasting Services Act defines forbidden online content, including specific representations of sexual acts and information on crime, violence and the use of certain narcotics.

听力原文:M. Mrs. Harrison, thanks very much for coming down here at the station. I, I know you've been through a terrible situation here today. Mm, I, I'd just like to go over some of the things you told Surgeon Clark at the bank.
W. All right.
M: Ah, ah. Would you like a cup of tea?
W. No, no, I'm fine.
M. All right.
W: Thanks.
M. Well, could you describe the two people who robbed the bank for this report we're filling out here? Now anything at all that you could remember would be extremely helpful to US.
W. Well, just, I tell you I remember basically what I said before.
M: That's all right.
W: The man was tall, about six feet, and he had dark hair.
M. Dark hair.
W: And he had a mustache.
M. Very good. All right. Did he have any other distinguishing marks, I mean, scars for example, anything like that?
W: Scars, no, none of that I can remember.
M. Do you remember how old he was by any chance?
W. Eh, well, I, I guess around thirty.
M. Around thirty.
W. Maybe younger, give a take of a few years.
M. All right. Do you remember anything about what he might be wearing?
W: Yes, he, he had on a dark sweater, solid color. You know, the kind of color young people fancy nowadays.
M: Anything else that strikes you at the moment?
W: I, I remember he was wearing a light shirt under the sweater, a cotton one with dark, I think, dark stripes. It looks like a good brand.
M: Ah, very good.
W: Yes, yes.
M. Mm, now, all right. Can you tell us anything about the woman robber, Mrs. Harrison?
W: Well, I remember that she did most of the talking. She had a gun pointed at us and she told us to lie down on the floor and not to move if we knew what was good for us. I, I remember I've just thought like she was pointing the gun right at me and my little daughter was sitting right next to me and she, she was just so frightened.
M. Um, Mrs. Harrison, could you describe her for us?
W: She was wearing a wool sweater.
M: Ah, very good.
W: I remember it was a dark color, navy blue or dark gray.
M: Dark gray?
W: And I guess she was in her late twenties. Her hair was short, very short and curly.
M: Do you remember how tall she was?
W: Ah, about the same as myself, around five four.
M: Five four. All right. Do you, uh, remember anything else about this woman?
W: Yes, I remember the woman was wearing a pendant or a locket around her neck. I remember it specifically because I was then near the counter next to the bank manager and my little daughter started to cry.
M: Ah.
W: And this woman came up and said: "Shut your damn kid up, lady!" So I got a good look at her and she was pulling on the chain and playing with it, a pendant.
M: Oh?
W: It was gold, well, anyway, lookes like gold. And it had a strange shape.
M: Mm, ah, now, did either of them have any other noticeable characteristics, Mrs. Harrison? Now, just take a minute.
W: Eh, no, I don't.
M: Think about this.
W: No, no, this is really all I can remember.
M: Well, did either of them wear glasses?
W: No, no, I'm sure of that.
M: All right, Mrs. Harrison. I really appreciate what you've been through today. I'm just going to ask you to look at some photographs before you leave if you don't mind. It won't take very long. Could you do that for me?
W: Ah, all right.
M. Would you like to step this way with me, please?
W. OK, sure.
M. Thank you.

Genetically-modified (GM) foodstuffs are here to stay.That’s not to say that food produced by conventional agriculture will disappear, but simply that food-buying patterns will polarize: there will be a niche market for conventional foodstuffs just as there is for organic food.It may even be that GM food will become the food of preference because consumers come to appreciate the health benefits of reduced pesticide use.
Currently there are some 20,000 chemicals in use, but the scientists only have detailed information around 1,000 of them.To see the advantages of GM food you have only to consider the recent press revelation that the average lettuce receives eleven pesticide applications before it reaches the supermarket shelf.I’m sure chemicals and their role in disease will become a big issue in the 21st century as the population of the developed world worries increasingly about its health.
The reason GM food will not go away is that we need a three-fold increase in food production by the year 2050 to keep pace with the world’s predicted population growth to ten or eleven billion.It’s not just a question of more mouths to feed either.What is often forgotten is that all these extra people will take up space, reducing the overall land available for agriculture.
The world has 800 million hungry people.Until now, food supplies have been increased by improved varieties, pesticides and artificial fertilizers: the green revolution.Now we’re on the edge of a new one: a genetic revolution.
It may well be that in the long term it is the developing world that benefits most from GM food.It is true that for the next years or so GM crops may be too expensive.
