【正文】 e off. Now, it39。 the exhaust pipe. We could fix things called absolute converters for exhaust pipe. It39。s not just what es out of the car exhaust that is dangerous, the brakes also cause pollution. The brakes in some cars give off asphaltum, and you know asphaltum is, is highly dangerous substance, and can kill us. And thirdly, the tyres themselves give off small rubber particle which is not very good for health.We need to find solutions to this problem. I39。 TALKOK, good afternoon, ladies and gentlemen. In the previous week we talked about different types of pollution, and this week I want to focus on air pollution, air pollution caused by the car. It39。聽力原文1996PART Ⅰ LISTENING COMPREHENSIONSECTION As well known that cars are the main cause of air pollution in a city. This can mean up to 50% of some diseases or even higher than 90 % of all air pollution are caused by the car. Obviously cars contribute a great deal to the air pollution in our cities, and this will get worse as the number of cars increases in the cities.Firstly, I would like to talk about how cars cause air pollution. How does the car cause air pollution? Well, you are all familiar with internal bustion engine, there is a mixture of petrol which explodes, and the explosion that propels the car forward. Unfortunately, in this process there are some poisonous chemicals made, and these poisonous chemicals mainly e out of the back of the car through the exhaust.Now it39。m going to talk about four possible solutions. Firstly, we could try and discourage the use of cars. We could do this by putting higher taxes on petrol, or we could make cars more expensive, we could put prices of cars up.Secondly, we might encourage alternative methods of transport. For example, recently in Shanghai, a new built supraunderground will take some of the pressure off the roads. Some people will use the subway rather than use cars.In addition we could improve public transport, make it more fortable, safer, more regular so that people will use the public transport rather than the car. Next, we could also use cleaner fuel rather than petrol. For example, we might use natural gas in the future or we might experiment battery in cars.And lastly, we could try mechanical means for reducing the amount of chemicals that are emitted, which es out of the cars39。s something, it39。s unlikely that any one of these solutions will work on its own. I39。 INTERVIEWInterviewer: So, you are an architect?Interviewee: Yes.Interviewer: Do you work for a public or private organization, or are you selfemployed, that is, working on your own?Interviewee: I39。t you try it? In fact, I have no preferences to where I work, public or private.Interviewer。m now working for a private firm. I worked for the government for about three years. It was all right. Of course, there is the bureaucracy one has to put up with, but that39。t mind bureaucratic wheels turning slowly, and things not being as efficient.Interviewer: Ahah. And what made you leave the public sector?Interviewee: Money mainly. You see, I got married, and my wife doesn39。s hard for me to be selfemployed because selfemployed work has the disadvantage that there may be time, or a period of time when you are unemployed.Interviewer: I see, so, did you join this pany straight away or ...Interviewee: No, I worked for ..., in a couple of private firms before I came to this one.Interviewer: Hmm ... hmm. Now, what qualifications does one have to have to bee an architect?Interviewee: Well, you39。 arts background too. You know, architecture is not a pure science.Interviewer: Now, if one wants to take up architecture, one has got to be able to draw? Is that really true?Interviewee: Well, it is true that the work of an architect involves a lot of drawing, and to be an architect you must be able to draw. But this doesn39。t at present draw, you won39。s drawing must be good in a sense that it gives a certain impression in the mind of the viewer, in fact, some famous artists can39。s drawing must be accurate. So, I39。s important.Interviewer。m not sure if I can generalize about that. You see architecture is a mixture of theory and practice. So I suppose a good architect should be good at both. An architect39。t collapse or can39。s dangerous. I don39。s predictable that if the building is constructed in a certain way, or with certain materials, we can say how long it will last, provided there39。 Er, for example, an earthquake or if the ground level sinks which may destroy it, so that39。s the theory side. Now, what about the practical aspect?Interviewee: Yes, the practical side concerns, I39。t think to himself. Oh, I39。d rather study in the library. My bedroom is too cold because the ceiling seems to be too high, and the windows too big. Or say, when somebody is cooking in the kitchen, the smell of the food shouldn39。s still in bed. The bathroom should be situated for everyone39。s being used, the noise shouldn39。 NEWS BROADCASTNews Item One (For Questions 11—12)A man who fired three shots into a crowded birthday party killing one man and wounding two other people has been sentenced to six years in prison. 36yearold Mark Eastwood was in court for sentencing today after a jury had found him guilty of manslaughter, but not guilty of murder.Mark Eastwood snapped after being kept awake for four successive nights by noisy parties yards away from his home.
