The buildings are made of glass, steel, and concrete. They were designed by an American architect, but he used a Malaysian style. They were finished in 1998, and they were the tallest buildings in the world at that time. Each tower has 88 floors, and is 452 meters high. I really like the Petronas Towers. They show both the modern and the traditional side of my countryTrack 41OL5amp。41OL6Modern buildings: We love them, We hate them The worldfamous Louvre Museum in Paris is almost 500 years old, and it faced a very modern problem: There simply wasn’t enough space for six million visitors each year. In 1989, American architect . Pei designed a striking glass pyramid in the building’s center to be a visitor entrance and shopping arcade. But he also started an angry debate. Some people felt his glass building was a piece of art, like the ones inside the museum. Others said it was just an ugly, modern mistake. Kyoto, Japan, is the country’s ancient capital, and the heart of its culture. Its railroad station was too small for the millions of visitors. In 1997, the city pleted a new station in a huge shopping center, right in the oldest part of the city. Designed by Hiroshi Hara, the building also contains a hotel and department store. Before it was built, critics said that the high, wide, modern building would destroy the city’s traditional look. On the other hand, supporters said it would bring new life into the city center.Track 41OL7amp。41OL8The future building boom?Interviewer: What do you think is the biggest problem facing our cities?Erika: I think it39。s overcrowding. Talk to anyone living in a major metropolitan area and they will say the same thing。 There39。s no space. Even the suburbs are getting crowded.Interviewer: Well, in some places there simply isn39。t any land left for building, right?Erika: Yes, that39。s true, but you have to think creatively. You can39。t give up so easily.Interviewer: Think creatively? What do you suggest?Erika: What I39。m saying is that we can build more structures underground. We can add parking lots,malls, hotels, and even apartment 39。s plenty of space.Interviewer: Isn39。t it expensive?Erika: Yes, it can be. In the past building underground has been very expensive. However, we have new technology that will bring the cost down. It involves using robots. You don39。t have to pay robots a salary! Interviewer: Isn39。t building down more dangerous than other kind of construction?Erika: Actually, I think it39。s safer than building skyscrapers, for example. Remember, we already do it. We have subways and underground shopping malls. I39。m just suggesting we invest in a variety of bigger projects and that we dig deeper.Interviewer: What would you say to people who doubt your idea?Erika: I can understand their feelings. Whenever there39。s a new idea, it can cause controversy. But building down is not some kind of impractical idea. It makes sense. There is so much space underground: It can acmodate a lot of traffic, storage, and people. With the new technology we have, we39。d be crazy not to consider the idea it39。s the wave of the future!UNIT2Track 421amp。422Situation 1Man: Oh no!Woman: What happened?Man: I can39。t believe it!
