7 Trees can also help break the force of the winds. The reason that high buildings may keep windier at ground level is that as the wind goes higher and higher, it goes faster and faster. When the wind hits the building, it has to go somewhere. Some of it goes over the top and some goes around the sides of the building, forcing those high level winds down to ground level. That doesn39。 t happen when you have trees. Trees filter the wind and considerably reduce it preventing those very large strong gusts that you so often find around tall buildings. Another problem in builtup areas is the traffic noise is intensified by tall buildings. By planting a belt of trees at the side of the road, you can make things a little quieter but much of the vehicle noise still goes through the trees. Trees can also help reduce the amount of noise in the surroundings, although the effect is not as large as people would like to think. Low frequency noise, in particular, just goes through the trees as that they aren39。 t there. Although trees can significantly improve the local climate, they do, however, take up a lot of space. There39。 re route system to consider and branches blocking the windows and so on. It may therefore be difficult to fit trees into the local landscape. There39。 s not a great deal you can do if you have what we call a street canyon, a whole set of highrises enclosed in the narrow street. Trees need water to grow. They also need some sunlight to grow and you need room to put them. If you have the chance of knocking buildings down and replacing them, then suddenly you can start looking at different ways to design the streets and to introduce...(End) test2_section1 W: Oh, Peter, there you39。 re. It39。 s been ages. What catches so long? M: Sorry, I39。 m so late, Sally. Have you been waiting long? W: Half an hour. But it doesn39。 t matter. I had a coffee and I had been reading this guidebook for tourists. Sit down. M: Umm. W: You look very hot and tired. What would you like to drink? M: I39。 d love really chill mineral water or something. Would you have another coffee? W: Yes, I39。 ll. The waitress will be back in a moment. Why are you so late. Did something happen? M: Yes. You know I went to the bank to cash something traveller39。 s cheques. Well the exchange 8 rate was looking very healthy but I went to the teller they told me that the puter system was temporarily down. So they couldn39。 t do any transactions. They said the problem would be fixed in a few minutes so I waited. And then I started talking to another guy in the bank and I fot the time. W: Oh, really? Someone you met in the bank. Does he work there? M: No, he was a tourist, from NY. His name is Henry. And he39。 s been here for a week, but he39。 s moving on to Germany tomorrow. He39。 s an architect and he39。 s spending four weeks travelling along Europe. W: Just like us? M: Yes, just like us. He told me the names of some places where we should eat. Great food and not too expensive, he said. Oh, and he also gave me this map of the buses to me, he said he didn39。 t need it anymore. W: That39。 s useful. But he39。 s moving on tomorrow. Yes, here39。 s the waitress. Let39。 s order. Do you want something to eat? Or should we just have a drink? M: Well. I39。 m hungry. And we39。 ve got a lot of sightseeing to do. So let39。 s just have a snack and drink. W: It sounds good to me. M: Well. Let39。 s decide what we39。 ll see today. I guess the best place to start is the Cathedral and then the Castle. What39。 re the opening times for those two? W: Well, according to this guidebook, the Cathedral is only open from in the morning until midday. (Ah...) No, hang on. That39。 s the Cathedral Museum. (Oh!) The Cathedral itself is open morning and afternoon. The Castle is just open from 1 to 5 so we can39。 t go there until after lunch. I really want to spend some time on the Art Gallery because they39。 ve got this wonderful painting by Rembrandt（倫伯朗） that I always want to see. M: What else should we see? W: Well the guidebook says the Botanical Gardens worth spending some time in. And there39。 re open all day from 8 to 6 so we go there anytime. (En...) I39。 d like to go to the markets near the river too. But ... Oh no way, that39。 s only in the mornings too. M: As well as today and tomorrow, we can see some other places on Monday you know. But I don39。 t think the markets will be open then. They only open on Thursdays. So we miss them for this week. Maybe we can go to the Cathedral today because it39。 s Sunday tomorrow. And even though it39。 s open every day it might be difficult to get in tomorrow because the chair services. 9 W: That is true. But the Art Gallery isn39。 t open on Sundays at all. So we39。 ll have to go there today. (En) The Castle is open every day except Monday. So it39。 ll okay there. And the Gardens of course is only closed at night. M: Are all these places free? Or do we have to pay to go in? What does the guidebook say? W: I think there39。 s a charge for all of them except the Botanical Gardens. Oh and the markets. Of course you don39。 t pay to go in. M: Okay, well, let39。 s have a look at our plan at this. We39。 ll go to see the painting, you like first, that the Rembrandt, then have lunch then we go on to the Castle after that and then the Cathedral. W: Okay. It says here that the roof of the Cathedral is really beautiful. M: Is that right? But I really want to do with the Cathedral is climb the tower. The view is supposed to be spectaculous! W: Okay well that39。 ll be more than enough today. And tomorrow let39。 s go to the Botanical Gardens and have a piic. (En!) I want to sit by the river and watch the swans. The city39。 s famous for them. test2_section2 So the Counselling Services we are for dealing with any problems arising from your studies or in your life outside the university.
