Read the text . Mark the sentences 1-5 T ( True ) , F ( False ) The end of a long journey Yesterday was an important day for Thomas Burns from Portsmouth . He retired after 45 years as a bus driver in the city . Here he writes about the changes he has seen over the years . ' Over the years a lot of things have changed in Portsmouth and I think it's more difficult to be a bus driver today than before . There are more cars , more cyclists , more traffic jams and more people in a hurry ! I've seen a lot of changes in the town center too . When I started you could drive along the High Street . Now you can't . It's for people on foot ! There are lots of roads you can't drive along . Another change is that 40 years ago we had conductors . Conductors were people who worked on the bus too and they walked up and down the bus and sold the tickets . Today the driver has to sell tickets . Also , the conductors watched the passengers for any trouble . Today we have CCTV cameras instead ! But a CCTV camera can't tell a teenager to get off the bus ! The passengers haven't changed a lot. I've met some really nice people and some very rude people too. But that's life, isn't it? Are the sentences true or false?
