Текст:
It was getting worse from day to day.There were just too many cars in the centre of london.Nobody could get anywhere in time ___. When Ken Livingstone, the Mayor of london,decided to do something about this, everybody said it would never work, but it did! In 2003, london became the first city in the world to introduce a " congestion charge". Drivers now have to pay 10 a day to enter the centre of london. At first people said ot would cause lots of problems because the technology used for paying the charge would break down. It didn`t! The Prime Minister at that time,Tony Blair,was also very worried,___. People began to see that traffic jams weren`t something__. The congestion charge has to be paid from Monday to Friday from 7 am to 6.30 pm. Since the introduction of the congestion charge,the number of cars per day in the centre of london has gone down by 50,000 and traffic jams by a third.Another positive effect is that traffic in the congestion charge zone between Piccadilly and Tower Bridge has started to move faster. However,the managers of big department stores are less happy___ since the congestion charge was introduced. Many people said that it was unfair that only people with money could drive into london because the congestion charge and parking together are too expensive for most people.And there are other problems,too. The Mayor ordered hundreds of new buses for all the extra passengers___.Unfortunately, however,people used the Tube instead,___. But many people think that, generally, the congestion charge has been a big success.Now comes the 64,000 guestion: would it work in other cities,too?
