London, like so many big cities, has traffic problems that seem to get worse and worse every year. Tom Jonkins, a London bus driver, was asked what he would do to improve the situation if he were put in charge of London Transport. This is what he said:
"If you put me in charge of London Transport, I’ d make a num ber of changes. I’d forbid private (私人的)cars to go through central between 7:00 a.m. and 6:30 p.m. unless the owners actually live in the area. I’d build a lot of new, cheap car parks near the railway sta tions on the skirts (效区) of the city so that people could leave their cars there and travel to and from work by train. I’d fix a standard fare (统一车费) for all bus or tube (地铁) journeys in the centre, and I’d make it possible for people to buy ten or a dozen tickets at one time at a reduced price; then the buses and taxis would be able to move much more quickly and easily, and life would become more comfortable for everyone./

A. Going to and from work by car makes the Londoners’ life very comfortable.
B. People would rather take buses than take the tube because the fare for the tube journeys is expensive.
C. This plan is against the private cars because it is made by a bus driver.
D. The car parks on the skirts of the city are not enough for the cars which are used by people to go to and from work.
