Experts now think computers can make it easier for the police to find people they want to question. At present, the system most widely used by the British police is called Photofit. Witnessesdescribe a suspect and then a picture is built up like a jigsaw, using five different sets of features.These are: hair, eyes, nose, mouth and chin. This system can be very useful itl finding criminals, but only in one case out of twenty, Quite often, almost half the time, in fact, Photofit pictures aremisleading. There are two reasons for this. Firstly, the picture may look nothing at all like the suspect. Secondly, the likeness may be so general that it is not at all helpful. And unfortunately, a bad likeness can lead to the arrest of an innocent person. Witnesses attitudes can influence their descriptions. In a recent experiment, a group of people was shown a picture of a man and told that he was a mass murderer. When asked to produce Photofit pictures of this man, they made pictures that showed a murderous-looking individual. But at the same time, a second group was shown the same picture and told that the same man was a lifeboat captain who had received a medal for bravery. When the second group produced Photofit pictures, these showed a man who was handsome and well-groomed. The police have another way of identifying criminals. Police records contain tens of thousands of photographs of people convicted of crimes. Witnesses can look through these in the hope of recognising suspects; however, it has been discovered that a witness begins to forget the culprits features after spending a long time looking through these photographs. A computer system called FRAME (Face Retrieval and Matching Equipment) combinesthe best features of both methods. All the photographs on record are put on the computer file. When a witness describes a suspect, the computer searches the file for photographs that fit the description. The witness is then presented with a small number of photographs to look through. Of course, this system, as it exists at present, will only help to identify people whose photographs are already on police files. So now, experts have to work on the problem of getting accurate descriptions from witnesses. One thing they have discovered is that witnesses give better descriptions when they are encouraged to recall the scene of the crime. They do not need to go there; just imagining the scene works just as well.Exercise A:1. Computers can make it easier for the police find people they want to question.2.

Section Two Listening ComprehensionPart 1 DialoguesDialogue 1 I Dont Believe ItA: No, I think its a load of rubbish myself. I mean, some people believe anything, dont they? Well, it doesnt make sense, does it? Things flying around in the sky, coming down from another planet and all that? No, I think when the scientists say its happened and we can explain how it happened - I mean, when we have some real proof, then Ill believe it.B: There could be some truth in it, but I tend to think its just a tourist attraction. 1 cant explain the photographs. And then there are the photographs of Bigfoot, the erm er, Abominable Snowman* in the mountains of India. Well, thats the same sort of thing. I suppose it could be true, but its the same with all these stories, youd like to see it for yourself before you believe it.C: Oh, yes. They definitely exist. Yes, I believe that some people come back to haunt* us. 1 mean, weve all had strange feelings about people who are no longer with ns, or strange feelings about certain places. I think those feelings are a kind of ghost. We dont always see something, you know, in a long white dress going whooo-ooo in the middle of the night, but we can have strong feelings about the past. Some people have very strong feelings so they actually begin to see things, something moving, a shape, a light, I dont know. Scientific facts cant explain everything in this world, you know.Exercise A:1. Probably some photographs of mysterious shapes, footprints or that sort of things.2. The first speaker.Exercise B:1. I only believe things when there is real proof or scientific explanation.2. People sometimes just duplicate old mysterious stories in a new setting to attract tourists.3. There de exist ghosts. When people have a very strong feeling about the past, they begin to see ghosts.Dialogue 2 Unidentified Flying ObjectsInterviewer: Mr Burton, you say that you have seen a UFO. Is that right?Mr Burton: Yes, absolutely right. It happened just over a year ago.Interviewer: And where was this?Mr Burton: Near my home in Aldershot, in the south of England. I live near the big military base in Aldershot.Interviewer: What time of day was it?Mr Burton: It was about one oclock in the morning. I was out fishing. The weather forecast said it was going to be a warm, clear night with no clouds, and thats perfect for fishing.Interviewer: And what happened?Mr Burton: Well, I saw a bright light coming towards me at about three hundred feet, and then it started to land. It was behind some trees, but I could see it clearly because there was a full moon. Then I saw two forms coming towards me, and when they were about five feet away, they just stopped and looked at me for a good ten or fifteen seconds.Interviewer: What did they look like?Mr Burton: They were quite small, about four feet tall, dressed in green suits from head to foot, and they had helmets of the same colour with a red visor*, so I couldnt see their faces. They both carried space guns.Interviewer: Did they speak to you?Mr Burton: Yes. The one on the right said Come this way, please.Interviewer: Werent you frightened? . I mean, werent you surprised that they spoke English?Mr Burton: They spoke in a funny accent. It sounded more like a machine talking than a person. No, I wasnt frightened. I dont know why. The one who spoke started to walk towards the light, and I followed him, with the other one behind me. We got to a wall and the first form just walked through it! I couldnt believe it! I had to climb over it, and then we got to the spaceship.Interviewer: What did that look like?Mr Burton: It was about forty-five feet across, and silver, very, very shiny, and there were round windows all round the side.Interviewer: Did you go inside?Mr Burton: Yes, I did. There were steps going up, and we went into an octagonal* room. I stood there for about ten minutes. The walls, the floor, and the ceiling were all black. I couldnt see any controls or instruments, but there was a central column going up from the floor to the ceiling, about four feel wide, right in the middle of the room.Interviewer: Were there any more of these forms?Mr Burton: No, just the two. Suddenly, one of them said Stand under the red light. I couldnt see any red light, but then I moved to the right and I could see it up on the wall, just under the ceiling. I stood there for about five minutes, and then a voice said What is your age? I said Seventy-four. Then they told me to turn around. After about five more minutes one of them said You can go. You are too old and ill for our purposes. So I left and went back, to the fiver.Interviewer: Did the spaceship take off?Mr Burton: Yes, I heard a very high-pitched noise, like a scream, and the thing took off straight into the sky and disappeared. I sat by the river and watched it go. This was about two oclock.Interviewer: Then what did you do?Mr Burton: Next morning I went to the police, and in the afternoon someone from the Ministry of Defense came to my house to interview me. He told me to keep quiet about the whole thing, and tell absolutely no one. I thought this was very strange, but I did as he told me.Interviewer: Why have you decided to tell people about it now?Mr Burton: Because I want people to know what happened to me. I didnt use to believe in UFOs, but now I know they exist. I think governments are trying to hide something, but people have a right to know,interviewer: Thank you, Mr Burton, very much. A fascinating storyExercise:A UFO ReportTime: One oclock in the morningPlace: Aldershot, in the south of EnglandDescription:A bright light was coming towards me at about three hundred feet. and it landed behind some trees. Then I saw two forms coming towards me Life form:They were quite small about four feet tall, dressed in green suits from head to foot, and they had helmets of the same colour with a red visor. They both carried space guns.Spaceship:It was about 45 feet across, and silver, very, very shiny, and there were round windows all round the side. There were steps going up. The interior of the spaceship is an octagonal room. The walls, the floor, and the ceiling were all black. There were no controls or instruments, but there was a central column going up from the floor to the ceiling, about four feet wide, right in the middle of the room.Part2 PassagePassage The Loch Ness MonsterOne of the strangest and most fascinating things about Scotland* is the Loch* Ness Monster, Some people believe in the monsters existence. Many do not! However, very important bodies of people do believe there is some truth in the famous monster story: experts from Britains Royal Air Force*, scientists from the Boston Academy of Applied Science* and computer specialists from NASA (National Aeronautics and Space Administration, U.S.A.), to mention but a few!Loch Ness is an enormous lake in Northern Scotland. It is about twenty-four miles long and one mile wide, and has an approximate depth of 1,000 feet, which makes it very difficult for anybody to find and examine the highly elusive* monster. In fact the first convincing reports of people seeing the monster date from only about six years before the beginning of the Second World War. Since then there have been other sightings, and photographs of the monster have been taken! Many of these photographs have later been recognised as fakes - silly jokes played on an unsuspecting public! However, other photographs have amazed the most searching scientific minds. In fact, it seems certain that something (and probably several of them) does exist in the deep waters of Loch Ness. The most amazing photographs show a flipper* - the flipper perhaps of a very large animal (twenty or thirty feet long, it is imagined). From these photos British specialist in animal life, Sir Peter Scott, who is also an artist, hasconstructed this picture of what he believes the monster might look like. But where did the monster come from? Did it mysteriously climb out of a prehistoric world beneath the earths crust*? Did it originally swim into the lake from the sea? Before the Ice Age, Loch Ness opened into the sea. Was the young monsters egg frozen into the ice of the Ice Age? And somehow did the monster come alive again when the ice went away? We just do not know! Can we ever find the answers to all the questions surrounding the legend* of the Loch Ness Monster, do you think?Exercise A:Loch Ness is an enormous lake in Northern Scotland.

Speaking to the BBC ahead of an Asian tour, Mrs Clinton said North Koreas nuclear plans, the economic crisis and climate change would top the agenda. Her week-long tour will take in Japan, China, South Korea and Indonesia. The stops reflect the diversity of ties the US has in this region. Going to Asia signals that the US is not just a transatlantic power but also a transpacific power. She also stressed that the US was keen to work more collaboratively with China. Mrs. Clinton said there were real opportunities to develop a good relationship with Beijing on issues such as climate change and clean energy. It is the first time in 60 years that a secretary of state has made Asia the destination of a first trip in office.A: This news item is about US intention to strengthen Asia ties.B: 参照原文News Item 2 A new round of six-nation talks on North Koreas nuclear program will be held next week in Beijing. The talks involving China, Russia, Japan, the United States, and North and South Korea have been scheduled for June 23-26. Working group talks set for June 21-22 will lay the groundwork for discussions later in the week. Beijing has already hosted two rounds of the so-called six-party talks, but both have made little headway into resolving the standoff*. China hopes all sides will deepen their discussions based on previously reached agreements, including to resolve.the crisis peacefully through dialogue and reaching the final goal of a nuclear freed Korean Peninsula. The United States and its key Asian allies, South Korea and Japan, have been pushing Pyongyang to abandon its nuclear program since the extent of the program became known in December 2002.Exercise A:This news item is about a new round of six-nation talks on North Koreas nuclear program.Exercise B:Directions: Listen to the news item and answer the following questions.1. What kind of talks will be held next week in Beijing? A new round of six-nation talks on North Koreas nuclear program will be held next week in Beijing.2.
